I found that using cast() was the best solution for me:

cast(Format(amount, "Standard") AS CHAR CHARACTER SET utf8) AS Amount

There is also a convert() function. More details on it here

Using "Store as a Global Variable" works, but it only gets the final instance of the object, and not the moment the object is being logged (since you're likely wanting to compare changes to the object as they happen). To get the object at its exact point in time of being modified, I use this...

function logObject(object) {
    console.info(JSON.stringify(object).replace(/,/g, ",\n"));
}

Call it like so...

logObject(puzzle);

You may want to remove the .replace(/./g, ",\n") regex if your data happens to have comma's in it.

I made a comparison between a ReadAllText and StreamBuffer for a 2Mb csv and it seemed that the difference was quite small but ReadAllText seemed to take the upper hand from the times taken to complete functions.

Using Stream

private static void copyFileUsingStream(File source, File dest) throws IOException {
    InputStream is = null;
    OutputStream os = null;
    try {
        is = new FileInputStream(source);
        os = new FileOutputStream(dest);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = is.read(buffer)) > 0) {
            os.write(buffer, 0, length);
        }
    } finally {
        is.close();
        os.close();
    }
}

Using Channel

private static void copyFileUsingChannel(File source, File dest) throws IOException {
    FileChannel sourceChannel = null;
    FileChannel destChannel = null;
    try {
        sourceChannel = new FileInputStream(source).getChannel();
        destChannel = new FileOutputStream(dest).getChannel();
        destChannel.transferFrom(sourceChannel, 0, sourceChannel.size());
       }finally{
           sourceChannel.close();
           destChannel.close();
       }
}

Using Apache Commons IO lib:

private static void copyFileUsingApacheCommonsIO(File source, File dest) throws IOException {
    FileUtils.copyFile(source, dest);
}

Using Java SE 7 Files class:

private static void copyFileUsingJava7Files(File source, File dest) throws IOException {
    Files.copy(source.toPath(), dest.toPath());
}

Or try Googles Guava :

Compare time:

    File source = new File("/Users/sidikov/tmp/source.avi");
    File dest = new File("/Users/sidikov/tmp/dest.avi");


    //copy file conventional way using Stream
    long start = System.nanoTime();
    copyFileUsingStream(source, dest);
    System.out.println("Time taken by Stream Copy = "+(System.nanoTime()-start));
     
    //copy files using java.nio FileChannel
    source = new File("/Users/sidikov/tmp/sourceChannel.avi");
    dest = new File("/Users/sidikov/tmp/destChannel.avi");
    start = System.nanoTime();
    copyFileUsingChannel(source, dest);
    System.out.println("Time taken by Channel Copy = "+(System.nanoTime()-start));
     
    //copy files using apache commons io
    source = new File("/Users/sidikov/tmp/sourceApache.avi");
    dest = new File("/Users/sidikov/tmp/destApache.avi");
    start = System.nanoTime();
    copyFileUsingApacheCommonsIO(source, dest);
    System.out.println("Time taken by Apache Commons IO Copy = "+(System.nanoTime()-start));
     
    //using Java 7 Files class
    source = new File("/Users/sidikov/tmp/sourceJava7.avi");
    dest = new File("/Users/sidikov/tmp/destJava7.avi");
    start = System.nanoTime();
    copyFileUsingJava7Files(source, dest);
    System.out.println("Time taken by Java7 Files Copy = "+(System.nanoTime()-start));

You could also check out the PLINQO set of code generation templates, based on CodeSmith, which allow you to do a lot of neat things for and with Linq-to-SQL:

• generate one file per class (instead of a single, huge file)
• update your model as needed
• many more features

Check out the PLINQO site at http://www.plinqo.com and have a look at the intro videos.

The second tool I know of are the Huagati DBML/EDMX tools, which allow update of DBML (Linq-to-SQL) and EDMX (Entity Framework) mapping files, and more (like naming conventions etc.).

I found out that you need to add the pointer eg:

div{
    cursor: url('cursorurl.png'), pointer;
}

function checkAll(class_name) {
    $("." + class_name).each(function () { 
        if (this.checked == true) 
            this.checked = false; 
        else 
            this.checked = true; 
    }); 
}

Try:

james.*jack

If you want both at the same time, then or them:

james.*jack|jack.*james

Have a look at GitHub - gspread.

I found it to be very easy to use and since you can retrieve a whole column by

first_col = worksheet.col_values(1)

and a whole row by

second_row = worksheet.row_values(2)

you can more or less build some basic select ... where ... = ... easily.

I generally agree with solutions given above. Namely with:

1. Using underscore in for-loop (2 and more lines)
2. Defining a normal while counter (3 and more lines)
3. Declaring a custom class with __nonzero__ implementation (many more lines)

If one is to define an object as in #3 I would recommend implementing protocol for with keyword or apply contextlib.

Further I propose yet another solution. It is a 3 liner and is not of supreme elegance, but it uses itertools package and thus might be of an interest.

from itertools import (chain, repeat)

times = chain(repeat(True, 2), repeat(False))
while next(times):
    print 'do stuff!'

In these example 2 is the number of times to iterate the loop. chain is wrapping two repeat iterators, the first being limited but the second is infinite. Remember that these are true iterator objects, hence they do not require infinite memory. Obviously this is much slower then solution #1. Unless written as a part of a function it might require a clean up for times variable.

I added this code

<input class="form-control input-small hasDatepicker" id="datepicker6" name="expire_date" type="text" value="2018-03-17 00:00:00">

<script src="/assets/js/datepicker/bootstrap-datepicker.js"></script>
<script>
        $(document).ready(function() {
            $("#datepicker6").datepicker({
                isRTL: true,
                dateFormat: "yy/mm/dd 23:59:59",
                changeMonth: true,
                changeYear: true

            });
        });
</script>

How are you calling split? It works like this:

def values = '1182-2'.split('-')
assert values[0] == '1182'
assert values[1] == '2'

If you have password for your dB then

mysql -u <username> -p <DBName> < yourfile.sql

If your address1 = '123 Center St' and address2 = 'Apt 3B' then even if you combine and do a LIKE, you cannot search on searchstring as 'Center St 3B'. However, if your searchstring was 'Center St Apt', then you can do it using -

WHERE (address1 + ' ' + address2) LIKE '%searchstring%'

Short answer: You can't. rm removes files blindly, with no concept of 'trash'.

Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i by default, but not all do.

Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete.

In the future, use rm with caution. Either create a del alias that provides interactivity, or use a file manager.

To go twice as fast by using multiple processor cores HPCsharp nuget package provides:

list.ToArrayPar();

DP size of any device is (actual resolution / density conversion factor).

Density conversion factor for density buckets are as follows:

ldpi: 0.75
mdpi: 1.0 (base density)
hdpi: 1.5
xhdpi: 2.0
xxhdpi: 3.0
xxxhdpi: 4.0

Examples of resolution/density conversion to DP:

• ldpi device of 240 X 320 px will be of 320 X 426.66 DP. 240 / 0.75 = 320 dp 320 / 0.75 = 426.66 dp

• xxhdpi device of 1080 x 1920 pixels (Samsung S4, S5) will be of 360 X 640 dp. 1080 / 3 = 360 dp 1920 / 3 = 640 dp

You can use any FTP client. I use winscp and it works just fine. In all these clients; you can specify the ssh secure key.

I think you could just do:

let array = [];
array.length = 2;
Object.defineProperty(array, 'length', {writable:false});


array[0] = 1 // [1, undefined]

array[1] = 2 // [1, 2]

array[2] = 3 // [1, 2] -> doesn't add anything and fails silently

array.push("something"); //but this throws an Uncaught TypeError

I had the same issue. I found that I forgot to add selenium-2.53.0/selenium-java-2.53.0-srcs.jar file to my project's Reference library.

new Buffer(number)            // Old
Buffer.alloc(number)          // New

new Buffer(string)            // Old
Buffer.from(string)           // New

new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New

new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New

Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

This code works for me:

class ViewController: UIViewController {

    var audioFilePathURL : NSURL!
    var soundSystemServicesId : SystemSoundID = 0

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        audioFilePathURL = NSBundle.mainBundle().URLForResource("MetalBell", withExtension: "wav")

        AudioServicesCreateSystemSoundID( audioFilePathURL, &soundSystemServicesId)


    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.


    }


    @IBAction func PlayAlertSound(sender: UIButton) {

         AudioServicesPlayAlertSound(soundSystemServicesId)
    }
}

You could use arraycopy but it depends on whether you can predefine the source array, - do you need a different character fill each time, or are you filling arrays repeatedly with the same char?

Clearly the length of the fill matters - either you need a source that is bigger than all possible destinations, or you need a loop to repeatedly arraycopy a chunk of data until the destination is full.

    char f = '+';
    char[] c = new char[50];
    for (int i = 0; i < c.length; i++)
    {
        c[i] = f;
    }

    char[] d = new char[50];
    System.arraycopy(c, 0, d, 0, d.length);

I had a nice time creating an Custom Attribute for this:

[AttributeUsage(AttributeTargets.Property, Inherited = false, AllowMultiple = false)]
public sealed class DecimalPrecisionAttribute : Attribute
{
    public DecimalPrecisionAttribute(byte precision, byte scale)
    {
        Precision = precision;
        Scale = scale;

    }

    public byte Precision { get; set; }
    public byte Scale { get; set; }

}

using it like this

[DecimalPrecision(20,10)]
public Nullable<decimal> DeliveryPrice { get; set; }

and the magic happens at model creation with some reflection

protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder)
{
    foreach (Type classType in from t in Assembly.GetAssembly(typeof(DecimalPrecisionAttribute)).GetTypes()
                                   where t.IsClass && t.Namespace == "YOURMODELNAMESPACE"
                                   select t)
     {
         foreach (var propAttr in classType.GetProperties(BindingFlags.Public | BindingFlags.Instance).Where(p => p.GetCustomAttribute<DecimalPrecisionAttribute>() != null).Select(
                p => new { prop = p, attr = p.GetCustomAttribute<DecimalPrecisionAttribute>(true) }))
         {

             var entityConfig = modelBuilder.GetType().GetMethod("Entity").MakeGenericMethod(classType).Invoke(modelBuilder, null);
             ParameterExpression param = ParameterExpression.Parameter(classType, "c");
             Expression property = Expression.Property(param, propAttr.prop.Name);
             LambdaExpression lambdaExpression = Expression.Lambda(property, true,
                                                                      new ParameterExpression[]
                                                                          {param});
             DecimalPropertyConfiguration decimalConfig;
             if (propAttr.prop.PropertyType.IsGenericType && propAttr.prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>))
             {
                 MethodInfo methodInfo = entityConfig.GetType().GetMethods().Where(p => p.Name == "Property").ToList()[7];
                 decimalConfig = methodInfo.Invoke(entityConfig, new[] { lambdaExpression }) as DecimalPropertyConfiguration;
             }
             else
             {
                 MethodInfo methodInfo = entityConfig.GetType().GetMethods().Where(p => p.Name == "Property").ToList()[6];
                 decimalConfig = methodInfo.Invoke(entityConfig, new[] { lambdaExpression }) as DecimalPropertyConfiguration;
             }

             decimalConfig.HasPrecision(propAttr.attr.Precision, propAttr.attr.Scale);
        }
    }
}

the first part is to get all classes in the model (my custom attribute is defined in that assembly so i used that to get the assembly with the model)

the second foreach gets all properties in that class with the custom attribute, and the attribute itself so i can get the precision and scale data

after that i have to call

modelBuilder.Entity<MODEL_CLASS>().Property(c=> c.PROPERTY_NAME).HasPrecision(PRECISION,SCALE);

so i call the modelBuilder.Entity() by reflection and store it in the entityConfig variable then i build the "c => c.PROPERTY_NAME" lambda expression

After that, if the decimal is nullable i call the

Property(Expression<Func<TStructuralType, decimal?>> propertyExpression) 

method (i call this by the position in the array, it's not ideal i know, any help will be much appreciated)

and if it's not nullable i call the

Property(Expression<Func<TStructuralType, decimal>> propertyExpression)

method.

Having the DecimalPropertyConfiguration i call the HasPrecision method.

You can use fs.promises available natively since Node v11.0.0

import fs from 'fs';

const readFile = async filePath => {
  try {
    const data = await fs.promises.readFile(filePath, 'utf8')
    return data
  }
  catch(err) {
    console.log(err)
  }
}

This will help exactly what you want

You can use initial which is explained here

You have two options either populate the value when calling form constructor:

form = JournalForm(initial={'tank': 123})

or set the value in the form definition:

tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123) 

Properties in your object are value types and you can use the shallow copy in such situation like that:

obj myobj2 = (obj)myobj.MemberwiseClone();

But in other situations, like if any members are reference types, then you need Deep Copy. You can get a deep copy of an object using Serialization and Deserialization techniques with the help of BinaryFormatter class:

public static T DeepCopy<T>(T other)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Context = new StreamingContext(StreamingContextStates.Clone);
        formatter.Serialize(ms, other);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

The purpose of setting StreamingContext: We can introduce special serialization and deserialization logic to our code with the help of either implementing ISerializable interface or using built-in attributes like OnDeserialized, OnDeserializing, OnSerializing, OnSerialized. In all cases StreamingContext will be passed as an argument to the methods(and to the special constructor in case of ISerializable interface). With setting ContextState to Clone, we are just giving hint to that method about the purpose of the serialization.

Additional Info: (you can also read this article from MSDN)

Shallow copying is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed; for a reference type, the reference is copied but the referred object is not; therefore the original object and its clone refer to the same object.

Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed. If a field is a reference type, a new copy of the referred object is performed.

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):

VARCHAR(65535)

However, note that the limit is lower if you use a multi-byte character set:

VARCHAR(21844) CHARACTER SET utf8

Here are some examples:

The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.

mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

But if we try decreasing lengths, we find the greatest length that works:

mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)

Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.

mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead

In spite of what the last error told us, InnoDB still doesn't like a length of 21845.

mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.

mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)

If you already know your remote branch like so...

git remote
=> One
=> Two

and you know the branch name you wish to checkout, for example, br1.2.3.4, then do

git fetch One
=> returns all meta data of remote, that is, the branch name in question.

All that is left is to checkout the branch

git checkout br.1.2.3.4

Then make any new branches off of it.

Use int function with second parameter 16, to convert a hex string to an integer. Finally, use hex function to convert it back to a hexadecimal number.

print hex(int("0xAD4", 16) + int("0x200", 16)) # 0xcd4

Instead you could directly do

print hex(int("0xAD4", 16) + 0x200) # 0xcd4

When you use a decorator, you're replacing one function with another. In other words, if you have a decorator

def logged(func):
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

then when you say

@logged
def f(x):
   """does some math"""
   return x + x * x

it's exactly the same as saying

def f(x):
    """does some math"""
    return x + x * x
f = logged(f)

and your function f is replaced with the function with_logging. Unfortunately, this means that if you then say

print(f.__name__)

it will print with_logging because that's the name of your new function. In fact, if you look at the docstring for f, it will be blank because with_logging has no docstring, and so the docstring you wrote won't be there anymore. Also, if you look at the pydoc result for that function, it won't be listed as taking one argument x; instead it'll be listed as taking *args and **kwargs because that's what with_logging takes.

If using a decorator always meant losing this information about a function, it would be a serious problem. That's why we have functools.wraps. This takes a function used in a decorator and adds the functionality of copying over the function name, docstring, arguments list, etc. And since wraps is itself a decorator, the following code does the correct thing:

from functools import wraps
def logged(func):
    @wraps(func)
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

@logged
def f(x):
   """does some math"""
   return x + x * x

print(f.__name__)  # prints 'f'
print(f.__doc__)   # prints 'does some math'

Had the same problem with base64. For anyone in the future with the same problem:

url = "data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAYAAAAUYybjAAAgAElE...";

This would work executed from console, but not from within a script:

$img.css("background-image", "url('" + url + "')");

But after playing with it a bit, I came up with this:

var img = new Image();
img.src = url;
$img.css("background-image", "url('" + img.src + "')");

No idea why it works with a proxy image, but it does. Tested on Firefox Dev 37 and Chrome 40.

Hope it helps someone.

EDIT

Investigated a little bit further. It appears that sometimes base64 encoding (at least in my case) breaks with CSS because of line breaks present in the encoded value (in my case value was generated dynamically by ActionScript).

Simply using e.g.:

$img.css("background-image", "url('" + url.replace(/(\r\n|\n|\r)/gm, "") + "')");

works too, and even seems to be faster by a few ms than using a proxy image.

This will do it regex: "^((19|20)\\d\\d)-(0?[1-9]|1[012])-(0?[1-9]|[12][0-9]|3[01])$" This will take care of valid formats and valid dates. It will not validate the correct days of the month i.e. leap year.

String regex = "^((19|20)\\d\\d)-(0?[1-9]|1[012])-(0?[1-9]|[12][0-9]|3[01])$";

Assert.assertTrue("Date: matched.", Pattern.matches(regex, "2011-1-1"));
Assert.assertFalse("Date (month): not matched.", Pattern.matches(regex, "2011-13-1"));

Good luck!

Replace implementation 'com.android.support:appcompat-v7:28.0.0-beta01' with

Have you tried doing a full "clean" and then rebuild in Eclipse (Project->Clean...)?

Are you able to compile and run with "javac" and "java" straight from the command line? Does that work properly?

If you right click on your project, go to "Properties" and then go to "Java Build Path", are there any suspicious entries under any of the tabs? This is essentially your CLASSPATH.

In the Eclipse preferences, you may also want to double check the "Installed JREs" section in the "Java" section and make sure it matches what you think it should.

You definitely have either a stale .class file laying around somewhere or you're getting a compile-time/run-time mismatch in the versions of Java you're using.

For UWP, I tried a different approach. I extended the ComboBox class, and processed the SelectionChanged and OnKeyUp events on the ComboBox as well as the Tapped event on the ComboBoxItems. In cases where I get a Tapped event or an Enter or Space key without first getting a SelectionChanged then I know the current item has been re-selected and I respond accordingly.

class ExtendedComboBox : ComboBox
{
    public ExtendedComboBox()
    {
        SelectionChanged += OnSelectionChanged;
    }

    protected override void PrepareContainerForItemOverride(Windows.UI.Xaml.DependencyObject element, object item)
    {
        ComboBoxItem cItem = element as ComboBoxItem;
        if (cItem != null)
        {
            cItem.Tapped += OnItemTapped;
        }

        base.PrepareContainerForItemOverride(element, item);
    }

    protected override void OnKeyUp(KeyRoutedEventArgs e)
    {
        // if the user hits the Enter or Space to select an item, then consider this a "reselect" operation
        if ((e.Key == Windows.System.VirtualKey.Space || e.Key == Windows.System.VirtualKey.Enter) && !isSelectionChanged)
        {
            // handle re-select logic here
        }

        isSelectionChanged = false;

        base.OnKeyUp(e);
    }

    // track whether or not the ComboBox has received a SelectionChanged notification
    // in cases where it has not yet we get a Tapped or KeyUp notification we will want to consider that a "re-select"
    bool isSelectionChanged = false;
    private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        isSelectionChanged = true;
    }

    private void OnItemTapped(object sender, TappedRoutedEventArgs e)
    {
        if (!isSelectionChanged)
        {
            // indicates that an item was re-selected  - handle logic here
        }

        isSelectionChanged = false;
    }
}

A faster way to

would be

If you have opened multiple files you may need to do a

:xa

As an addendum to this, I've strings of the form: Some words 303

where I'd like to split off the numerical part from the tail of the string. This seems to point to a possible solution:

http://lists.mysql.com/mysql/222421

The problem however, is that you only get the answer "yes, it matches", and not the start index of the regexp match.

Try using below:

SELECT 
    (RTRIM(LTRIM(col_1))) + (RTRIM(LTRIM(col_2))) AS Col_newname,
    col_1,
    col_2 
FROM 
    s_cols 
WHERE
    col_any_condition = ''
;

For brevity, here's an ES2015 sample that doesn't rely on global variables

// controllers/example-controller.js

export const ExampleControllerName = "ExampleController"
export const ExampleController = ($scope) => {
  // something... 
}

// controllers/another-controller.js

export const AnotherControllerName = "AnotherController"
export const AnotherController = ($scope) => {
  // functionality... 
}

// app.js

import angular from "angular";

import {
  ExampleControllerName,
  ExampleController
} = "./controllers/example-controller";

import {
  AnotherControllerName,
  AnotherController
} = "./controllers/another-controller";

angular.module("myApp", [/* deps */])
  .controller(ExampleControllerName, ExampleController)
  .controller(AnotherControllerName, AnotherController)

I solved this using jQuery. Until new CSS rules allow for this type of behavior natively I find it is the best way to do it.

Setup your divs

Below you have your div that you want the background to appear on ("hero") and then the inner content/text you want to overlay on top of your background image ("inner"). You can (and should) move the inline styles to your hero class. I left them here so it's quick and easy to see what styles are applied to it.

<div class="hero" style="background-image: url('your-image.png'); background-size: 100%; background-repeat: no-repeat; width: 100%;">
    <div class="inner">overlay content</div>
</div>

Calculate image aspect ratio

Next calculate your aspect ratio for your image by dividing the height of your image by the width. For example, if your image height is 660 and your width is 1280 your aspect ratio is 0.5156.

Setup a jQuery window resize event to adjust height

Finally, add a jQuery event listener for window resize and then calculate your hero div's height based off of the aspect ratio and update it. This solution typically leaves an extra pixel at the bottom due to imperfect calculations using the aspect ratio so we add a -1 to the resulting size.

$(window).on("resize", function ()
{
    var aspect_ratio = .5156; /* or whatever yours is */
    var new_hero_height = ($(window).width()*aspect_ratio) - 1;
    $(".hero").height(new_hero_height);
}

Ensure it works on page load

You should perform the resize call above when the page loads to have the image sizes calculated at the outset. If you don't, then the hero div won't adjust until you resize the window. I setup a separate function to do the resize adjustments. Here's the full code I use.

function updateHeroDiv()
{
    var aspect_ratio = .5156; /* or whatever yours is */
    var new_hero_height = ($(window).width()*aspect_ratio) - 1;
    $(".hero").height(new_hero_height);
}

$(document).ready(function() 
{       
    // calls the function on page load
    updateHeroDiv(); 

    // calls the function on window resize
    $(window).on("resize", function ()
    {
        updateHeroDiv();        
    }
});

I would use regex for this purpose:

myString = '  this Is my sTring.  ';
myString.trim().toLowerCase().replace(/\w\S*/g, (w) => (w.replace(/^\w/, (c) => c.toUpperCase())));

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

As "me1" has mentioned you can do this assuming that your version of Windows 7 is either Professional or Ultimate, the PC is on the domain and you have preinstall the Remote Server Administration Tools (Windows6.1-KB958830-x64-RefreshPkg.msu or newer) then you'll be able to do the following:

Step 1. Select "Start", select "Control Panel", select "Programs" and click on "Turn Windows features on or off".

Step 2. Check the following 5 features:

"remote server administration tools>feature administration tools>group policy management tools"

"remote server administration tools>feature administration tools>smtp server tools"

"remote server administration tools>role administration tools>ad ds and ad lds tools>active directory module for windows powershell"

"remote server administration tools>role administration tools>ad ds and ad lds tools>ad ds tools>active directory administrative center"

"remote server administration tools>role administration tools>ad ds and ad lds tools>ad ds tools>ad ds snap-ins and command-line tools"

Step 3. Click "OK".

// Set up the Select2 control
$('#mySelect2').select2({
    ajax: {
        url: '/api/students'
    }
});

// Fetch the preselected item, and add to the control
var studentSelect = $('#mySelect2');
$.ajax({
    type: 'GET',
    url: '/api/students/s/' + studentId
}).then(function (data) {
    // create the option and append to Select2
    var option = new Option(data.full_name, data.id, true, true);
    studentSelect.append(option).trigger('change');

    // manually trigger the `select2:select` event
    studentSelect.trigger({
        type: 'select2:select',
        params: {
            data: data
        }
    });
});

As far as I know, it's not possible to change the content of the buttons, at least not easily. It's fairly easy to have your own custom alert box using JQuery UI though

Also don't forget the obvious, does the data in the tables need to have case? You could only insert rows already in lower case (or convert the existing DB rows to lower case) and be done with it right from the start.

Just use the following command

git show a2c25061

or (the exact equivalent):

git log -p -1 a2c25061

I am using ubuntu 14.04. I have genymotion installed on virtualbox. Every time I start genymotion I had no problem, but suddenly one time it said unable to load virtualbox engine and it didn't open. I went through the log file and found out it could not create a new host only network because it has already created all possible host only networks. And the problem is that it cannot allocate memory for a new network.

Fix: go to your virtual box File --> Preferences --> Network

Click the host-only tab and just delete some of the host-only networks so that you will get some memory freed and next time, a new network can be created easily.

Deletion fixed my problem.

One shouldn't use set_yticklabels to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter), which is usually undesired. The easiest is to set the respective tick_params:

ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)

or

ax.tick_params(labelsize=8)

in case both axes shall have the same size.

Of course using the rcParams as in @tmdavison's answer is possible as well.

How about:

if (stream.markSupported() == false) {

        // lets replace the stream object
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        IOUtils.copy(stream, baos);
        stream.close();
        stream = new ByteArrayInputStream(baos.toByteArray());
        // now the stream should support 'mark' and 'reset'

    }

I was seeing this error on Chrome while I was testing my code locally. I switched to Firefox and I am not seeing the error any more. Maybe switching to another browser is a quick fix.

If you are using the solution given in first answer, then make sure you add img.crossOrigin = "Anonymous"; just after you declare the img variable (for eg. var img = new Image();).

Post the string with raw JSON, and do not forget the double quotation marks!

I had to do this on CentOS 5.8. Running bundle install kept causing issues since I couldn't force it to use a particular PG version.

I can't yum erase postgresql postgresql-devel either, because of dependency issues (it would remove php, http etc)

The solution? Mess $PATH temporarily to give preference to the update pgsql instead of the default one:

export PATH=/usr/pgsql-9.2/bin:$PATH
bundle install

Basically, with the above commands, it will look at /usr/pgsql-9.2/bin/pg_config before the one in /usr/bin/pg_config

Arduino specifically provides absolutely no way to exit their loop function, as exhibited by the code that actually runs it:

setup();

for (;;) {
    loop();
    if (serialEventRun) serialEventRun();
}

Besides, on a microcontroller there isn't anything to exit to in the first place.

The closest you can do is to just halt the processor. That will stop processing until it's reset.

The solution that worked for me is weird

1. Simply remove the all the break points
2. Restart tomcat in debug mode (using catalina.sh jpda start)
3. Now try to connect and it worked!!!!

First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function

function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
    $databaseConnectionQuery =  mysqli_connect($serverName, $userName, $password, $databaseName);
    if($databaseConnectionQuery === false)
    {
        die("ERROR: Could not connect. " . mysqli_connect_error());
        return false;
    }

    $resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
    $fetchFields = mysqli_fetch_fields($resultQuery);
    $fetchValues = mysqli_fetch_fields($resultQuery);

    if (mysqli_num_rows($resultQuery) > 0) 
    {           

        echo "<table class='table'>";
        echo "<tr>";
        foreach ($fetchFields as $fetchedField)
         {          
            echo "<td>";
            echo "<b>" . $fetchedField->name . "<b></a>";
            echo "</td>";
        }       
        echo "</tr>";
        while($totalRows = mysqli_fetch_array($resultQuery)) 
        {           
            echo "<tr>";                                
            for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
            {           
                echo "<td>";
                echo $totalRows[$eachRecord];
                echo "</td>";               
            }
            echo "<td><a href=''><button>Edit</button></a></td>";
            echo "<td><a href=''><button>Delete</button></a></td>";
            echo "</tr>";           
        } 
        echo "</table>";        

    } 
    else
    {
      echo "No Records Found in";
    }
}

All set now Pass the arguments as For Example

$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;

Here

localhost indicates Name of the host,

root indicates the username for database

root@123 indicates the password for the database

$queryStatment for generating Query

hope it helps

use StringBuilder and iterate over your String[], and append each String into it:

public static String convert(String[] name) { 
    StringBuilder sb = new StringBuilder();
    for (String st : name) { 
        sb.append('\'').append(st).append('\'').append(',');
    }
    if (name.length != 0) sb.deleteCharAt(sb.length()-1);
    return sb.toString();
}

If you know the key which you unset then put directly by comma separated

unset($attr['placeholder'], $attr['autocomplete']);

You can also work with a so called boolean vector, aka logical:

row_to_keep = c(TRUE, FALSE, TRUE, FALSE, TRUE, FALSE, TRUE)
myData = myData[row_to_keep,]

Note that the ! operator acts as a NOT, i.e. !TRUE == FALSE:

myData = myData[!row_to_keep,]

This seems a bit cumbersome in comparison to @mrwab's answer (+1 btw :)), but a logical vector can be generated on the fly, e.g. where a column value exceeds a certain value:

myData = myData[myData$A > 4,]
myData = myData[!myData$A > 4,] # equal to myData[myData$A <= 4,]

You can transform a boolean vector to a vector of indices:

row_to_keep = which(myData$A > 4)

Finally, a very neat trick is that you can use this kind of subsetting not only for extraction, but also for assignment:

myData$A[myData$A > 4,] <- NA

where column A is assigned NA (not a number) where A exceeds 4.

Yes. Thanks

For UTF-8 textual information, you should use utf8_general_ci because...

• utf8_bin: compare strings by the binary value of each character in the string

• utf8_general_ci: compare strings using general language rules and using case-insensitive comparisons

a.k.a. it will should making searching and indexing the data faster/more efficient/more useful.

Just use ng-repeat="(sectionIndex, section) in sections"

and that will be useable on the next level ng-repeat down.

<ul ng-repeat="(sectionIndex, section) in sections">
    <li  class="section_title {{section.active}}" >
        {{section.name}}
    </li>
    <ul>
        <li ng-repeat="tutorial in section.tutorials">
            {{tutorial.name}}, Your section index is {{sectionIndex}}
        </li>
    </ul>
</ul>

To sum up all of the options for VS 2017, WebHelpers was installed by installing MVC in previous versions of Visual Studio. If you're getting this error, you probably don't have the older versions of VS installed anymore.

So, installing the Microsoft.AspNet.MVC NuGet package will require Microsoft.AspNet.WebPages and Microsoft.AspNet.Razor, and the Microsoft.AspNet.WebPages includes System.Web.Helpers.dll.

If you've got direct references to System.Web.Mvc.dll and you don't want to use NuGet for MVC, you can get the Microsoft.AspNet.WebPages NuGet, or there are some other NuGet packages that only contain System.Web.Helpers.dll, like the microsoft-web-helpers or System-Web-Helpers.dllpackages.

There appear to be 2 versions of System.Web.Helpers.dll, one for .Net 4.0 and one for 4.5. Choosing the correct version of MVC or AspNet.WebPages will ensure you get the right one.

I made it work with this:

.element {
   transition: height 3s ease-out, width 5s ease-in;
}

you can probably do it like this:

String k = null;
String v = null;
options.put(k,v);

enums are classes in Java. They have an implicit ordinal value, starting at 0. If you want to store an additional field, then you do it like for any other class:

public enum MyEnum {

    ONE(1),
    TWO(2);

    private final int value;

    private MyEnum(int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }
}

When you create an object myObj as you have, think of it more like a dictionary. In this case, it has two keys, name, and age.

You can access these dictionaries in two ways:

• Like an array (e.g. myObj[name]); or
• Like a property (e.g. myObj.name); do note that some properties are reserved, so the first method is preferred.

You should be able to access it as a property without any problems. However, to access it as an array, you'll need to treat the key like a string.

myObj["name"]

Otherwise, javascript will assume that name is a variable, and since you haven't created a variable called name, it won't be able to access the key you're expecting.

For CSS, I found that max height of 180 is better for mobile phones landscape 320 when showing browser chrome.

.scrollable-menu {
    height: auto;
    max-height: 180px;
    overflow-x: hidden;
}

Also, to add visible scrollbars, this CSS should do the trick:

.scrollable-menu::-webkit-scrollbar {
    -webkit-appearance: none;
    width: 4px;        
}    
.scrollable-menu::-webkit-scrollbar-thumb {
    border-radius: 3px;
    background-color: lightgray;
    -webkit-box-shadow: 0 0 1px rgba(255,255,255,.75);        
}

This answer from another forum solved the problem.

(substitute your own range for the "I:I" shown here)

Re: CountA not working in VBA

Should be:

Nonblank = Application.WorksheetFunction.CountA(Range("I:I"))

You have to refer to ranges in the vba format, not the in-excel format.

*X*YZ* = string contains X and contains YZ

@".*X.*YZ"

X*YZ*P = string starts with X, contains YZ and ends with P.

@"^X.*YZ.*P$"

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

References are "hidden pointers" (non-null) to things which can change (lvalues). You cannot define them to a constant. It should be a "variable" thing.

EDIT::

I am thinking of

int &x = y;

as almost equivalent of

int* __px = &y;
#define x (*__px)

where __px is a fresh name, and the #define x works only inside the block containing the declaration of x reference.

This also works in Java 8 :

Might help some else - I came here because I missed putting two // after http:. This is what I had:

I also stumbled over this problem recently. Here is my solution. I wanted to avoid recursion, so I used a while loop.

Because of the adds and removes in arbitrary places on the list, I went with the LinkedList implementation.

/* traverses tree starting with given node */
  private static List<Node> traverse(Node n)
  {
    return traverse(Arrays.asList(n));
  }

  /* traverses tree starting with given nodes */
  private static List<Node> traverse(List<Node> nodes)
  {
    List<Node> open = new LinkedList<Node>(nodes);
    List<Node> visited = new LinkedList<Node>();

    ListIterator<Node> it = open.listIterator();
    while (it.hasNext() || it.hasPrevious())
    {
      Node unvisited;
      if (it.hasNext())
        unvisited = it.next();
      else
        unvisited = it.previous();

      it.remove();

      List<Node> children = getChildren(unvisited);
      for (Node child : children)
        it.add(child);

      visited.add(unvisited);
    }

    return visited;
  }

  private static List<Node> getChildren(Node n)
  {
    List<Node> children = asList(n.getChildNodes());
    Iterator<Node> it = children.iterator();
    while (it.hasNext())
      if (it.next().getNodeType() != Node.ELEMENT_NODE)
        it.remove();
    return children;
  }

  private static List<Node> asList(NodeList nodes)
  {
    List<Node> list = new ArrayList<Node>(nodes.getLength());
    for (int i = 0, l = nodes.getLength(); i < l; i++)
      list.add(nodes.item(i));
    return list;
  }

Event.preventDefault- stops browser default behaviour. Now comes what is browser default behaviour. Assume you have a anchor tag and it has got a href attribute and this anchor tag is nested inside a div tag which has got a click event. Default behaviour of anchor tag is when clicked on the anchor tag it should navigate, but what event.preventDefault does is it stops the navigation in this case. But it never stops the bubbling of event or escalation of event i.e

<div class="container">
 <a href="#" class="element">Click Me!</a>
</div>

$('.container').on('click', function(e) {
 console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  console.log('element was clicked');
});

The result will be

"element was clicked"

"container was clicked"

Now event.StopPropation it stops bubbling of event or escalation of event. Now with above example

$('.container').on('click', function(e) {
  console.log('container was clicked');
});

$('.element').on('click', function(e) {
  e.preventDefault(); // Now link won't go anywhere
  e.stopPropagation(); // Now the event won't bubble up
 console.log('element was clicked');
});

Result will be

"element was clicked"

I just improve the groovy script from above to write the property in the root parent properties file:

import java.io.*;
String p = project.properties['env-properties-file']
File f = new File(p)
if (f.exists()) {
try{
FileWriter fstream = new FileWriter(f.getAbsolutePath())
BufferedWriter out = new BufferedWriter(fstream)
String propToSet = f.getAbsolutePath().substring(0, f.getAbsolutePath().lastIndexOf(File.separator))
if (File.separator != "/") {
propToSet = propToSet.replace(File.separator,File.separator+File.separator+File.separator)
}
out.write("jacoco.agent = " + propToSet + "/lib/jacocoagent.jar")
out.close()
}catch (Exception e){
}
}
String ret = "../"
while (!f.exists()) {
f = new File(ret + p)
ret+= "../"
}
project.properties['env-properties-file-by-groovy'] = f.getAbsolutePath()

Its easy go to File - Data Modeler - Import - Data Dictionary - DB connection - OK

here is an example

 <a class="facultySelecter" data-faculty="ahs" href="#">Arts and Human Sciences</a></li>

    $('.facultySelecter').click(function() {        
    var unhide = $(this).data("faculty");
    });

this would set var unhide as ahs, so use .data("foo") to get the "foo" value of the data-* attribute you're looking to get

Using only virtualenv (without virtualenvwrapper), setting environment variables is easy through the activate script you sourcing in order to activate the virtualenv.

Run:

nano YOUR_ENV/bin/activate

Add the environment variables to the end of the file like this:

export KEY=VALUE

You can also set a similar hook to unset the environment variable as suggested by Danilo Bargen in his great answer above if you need.

Function xrand() As Long
        Dim r1 As Long = Now.Day & Now.Month & Now.Year & Now.Hour & Now.Minute & Now.Second & Now.Millisecond
        Dim RAND As Long = Math.Max(r1, r1 * 2)
        Return RAND
End Function

.Range(.Cells(RangeStartRow, RangeStartColumn), .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does (and similarly in some other cases).

Solution #2: Activate Worksheets("Cable Cards") prior to using its cells.

Explanation: Cells(RangeStartRow, RangeStartColumn) (e.g.) gives you a Range, that would be ok, and that is why you often see Cells used in this way. But since it is not applied to a specific object, it applies to the ActiveSheet. Thus, your code attempts using .Range(rng1, rng2), where .Range is a method of one Worksheet object and rng1 and rng2 are in a different Worksheet.

There are two checks that you can do to make this quite evident:

1. Activate your Worksheets("Cable Cards") prior to executing your Sub and it will start working (now you have well-formed references to Ranges). For the code you posted, adding .Activate right after With... would indeed be a solution, although you might have a similar problem somewhere else in your code when referring to a Range in another Worksheet.

2. With a sheet other than Worksheets("Cable Cards") active, set a breakpoint at the line throwing the error, start your Sub, and when execution breaks, write at the immediate window

   Debug.Print Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   Debug.Print .Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   and see the different outcomes.

Conclusion: Using Cells or Range without a specified object (e.g., Worksheet, or Range) might be dangerous, especially when working with more than one Sheet, unless one is quite sure about what Sheet is active.

There's no casting in javascript, so you cannot throw if "casting fails".
Typescript supports casting but that's only for compilation time, and you can do it like this:

const toDo = <IToDoDto> req.body;
// or
const toDo = req.body as IToDoDto;

You can check at runtime if the value is valid and if not throw an error, i.e.:

function isToDoDto(obj: any): obj is IToDoDto {
    return typeof obj.description === "string" && typeof obj.status === "boolean";
}

@Post()
addToDo(@Response() res, @Request() req) {
    if (!isToDoDto(req.body)) {
        throw new Error("invalid request");
    }

    const toDo = req.body as IToDoDto;
    this.toDoService.addToDo(toDo);
    return res.status(HttpStatus.CREATED).end();
}

Edit

As @huyz pointed out, there's no need for the type assertion because isToDoDto is a type guard, so this should be enough:

if (!isToDoDto(req.body)) {
    throw new Error("invalid request");
}

this.toDoService.addToDo(req.body);

Passing Props to Nested Children

With the update to React 16.6 you can now use React.createContext and contextType.

import * as React from 'react';

// React.createContext accepts a defaultValue as the first param
const MyContext = React.createContext(); 

class Parent extends React.Component {
  doSomething = (value) => {
    // Do something here with value
  };

  render() {
    return (
       <MyContext.Provider value={{ doSomething: this.doSomething }}>
         {this.props.children}
       </MyContext.Provider>
    );
  }
}

class Child extends React.Component {
  static contextType = MyContext;

  onClick = () => {
    this.context.doSomething(this.props.value);
  };      

  render() {
    return (
      <div onClick={this.onClick}>{this.props.value}</div>
    );
  }
}


// Example of using Parent and Child

import * as React from 'react';

class SomeComponent extends React.Component {

  render() {
    return (
      <Parent>
        <Child value={1} />
        <Child value={2} />
      </Parent>
    );
  }
}

React.createContext shines where React.cloneElement case couldn't handle nested components

class SomeComponent extends React.Component {

  render() {
    return (
      <Parent>
        <Child value={1} />
        <SomeOtherComp><Child value={2} /></SomeOtherComp>
      </Parent>
    );
  }
}

But, now you can go for NURLCredential instead of keychain wrapper. It does what we need to do.

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.

Option #1 (Markdown code-blocks)

Discord supports Markdown and uses highlight.js to highlight code-blocks. Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.

To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).

```language
message
```

Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).

Option #2 (Embeds)

Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

(Embed Cheat-sheet)

Here is another way with leading '0' for all of them.

$secCount = 10000;
$hours = str_pad(floor($secCount / (60*60)), 2, '0', STR_PAD_LEFT);
$minutes = str_pad(floor(($secCount - $hours*60*60)/60), 2, '0', STR_PAD_LEFT);
$seconds = str_pad(floor($secCount - ($hours*60*60 + $minutes*60)), 2, '0', STR_PAD_LEFT);

It is an adaptation from the answer of Flaxious.

I had the same problem and I created a new listener for it and used in my fragments.

1 - Your activity should have a listener interface and a list of listeners in it

2 - You should implement methods for adding and removing the listeners

3 - You should override the onBackPressed method to check that any of the listeners use the back press or not

public class MainActivity ... {

    /**
     * Back press listener list. Used for notifying fragments when onBackPressed called
     */
    private Stack<BackPressListener> backPressListeners = new Stack<BackPressListener>();


    ...

    /**
     * Adding new listener to back press listener stack
     * @param backPressListener
     */
    public void addBackPressListener(BackPressListener backPressListener) {
        backPressListeners.add(backPressListener);
    }

    /**
     * Removing the listener from back press listener stack
     * @param backPressListener
     */
    public void removeBackPressListener(BackPressListener backPressListener) {
        backPressListeners.remove(backPressListener);
    }


    // Overriding onBackPressed to check that is there any listener using this back press
    @Override
    public void onBackPressed() {

        // checks if is there any back press listeners use this press
        for(BackPressListener backPressListener : backPressListeners) {
            if(backPressListener.onBackPressed()) return;
        }

        // if not returns in the loop, calls super onBackPressed
        super.onBackPressed();
    }

}

4 - Your fragment must implement the interface for back press

5 - You need to add the fragment as a listener for back press

6 - You should return true from onBackPressed if the fragment uses this back press

7 - IMPORTANT - You must remove the fragment from the list onDestroy

public class MyFragment extends Fragment implements MainActivity.BackPressListener {


    ...

    @Override
    public void onAttach(Activity activity) {
        super.onCreate(savedInstanceState);

        // adding the fragment to listener list
        ((MainActivity) activity).addBackPressListener(this);
    }

    ...

    @Override
    public void onDestroy() {
        super.onDestroy();

        // removing the fragment from the listener list
        ((MainActivity) getActivity()).removeBackPressListener(this);
    }

    ...

    @Override
    public boolean onBackPressed() {

        // you should check that if this fragment is the currently used fragment or not
        // if this fragment is not used at the moment you should return false
        if(!isThisFragmentVisibleAtTheMoment) return false;

        if (isThisFragmentUsingBackPress) {
            // do what you need to do
            return true;
        }
        return false;
    }
}

There is a Stack used instead of the ArrayList to be able to start from the latest fragment. There may be a problem also while adding fragments to the back stack. So you need to check that the fragment is visible or not while using back press. Otherwise one of the fragments will use the event and latest fragment will not be closed on back press.

I hope this solves the problem for everyone.

I've used min-height: 100vh; with great success on some of my projects. See example.

By mid-2016 the Chromium engine (v53) supports just 3 emphasis styles:

Plain text, bold, and super-bold...

 <div style="font:normal 400 14px Arial;">Testing</div>

 <div style="font:normal 700 14px Arial;">Testing</div>

 <div style="font:normal 800 14px Arial;">Testing</div>

try doing this

<div style="position: absolute;top: 32px; left: 430px;" id="outerFilterDiv">
<input name="filterTextField" type="text" id="filterTextField" tabindex="2"  style="width: 140px;
    position: absolute; top: 1px; left: 1px; z-index: 2;border:none;" />
        <div style="position: absolute;" id="filterDropdownDiv">
<select name="filterDropDown" id="filterDropDown" tabindex="1000"
    onchange="DropDownTextToBox(this,'filterTextField');" style="position: absolute;
    top: 0px; left: 0px; z-index: 1; width: 165px;">
    <option value="-1" selected="selected" disabled="disabled">-- Select Column Name --</option>
</select>

please look at following example fiddle

I have used wxWidgets for small project and I loved it. Qt is another good choice but for commercial use you would probably need to buy a licence. If you write in C++ don't use Win32 API as you will end up making it object oriented. This is not easy and time consuming. Also Win32 API has too many macros and feels over complicated for what it offers.

You can use general compound drawable implementation, but if you need to define a size of drawable use this library:

https://github.com/a-tolstykh/textview-rich-drawable

Here is a small example of usage:

<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Some text"
        app:compoundDrawableHeight="24dp"
        app:compoundDrawableWidth="24dp" />

I think your problem is that the match method is returning an array. The 0th item in the array is the original string, the 1st thru nth items correspond to the 1st through nth matched parenthesised items. Your "alert()" call is showing the entire array.

The modern way is to use the CSS flexbox, see support tables.

.container {_x000D_
  display: flex;_x000D_
}_x000D_
.container > div {_x000D_
  flex: 1; /*grow*/_x000D_
}

<div class="container">_x000D_
  <div>Left div</div>_x000D_
  <div>Middle div</div>  _x000D_
  <div>Right div</div>_x000D_
</div>

You can also use CSS grid, see support tables.

.container {_x000D_
  display: grid;_x000D_
  grid-template-columns: 1fr 1fr 1fr; /* fraction*/_x000D_
}

<div class="container">_x000D_
  <div>Left div</div>_x000D_
  <div>Middle div</div>  _x000D_
  <div>Right div</div>_x000D_
</div>

You can use a case in this case, to separate versions one example is using FACT os (which returns the version etc of your system... the command facter will return the details:

root@sytem# facter -p os
{"name"=>"CentOS", "family"=>"RedHat", "release"=>{"major"=>"7", "minor"=>"0", "full"=>"7.0.1406"}}

#we capture release hash
$curr_os = $os['release']

case $curr_os['major'] {
  '7': { .... something }
  *: {something}
}

That is an fast example, Might have typos, or not exactly working. But using system facts you can see what happens.

The OS fact provides you 3 main variables: name, family, release... Under release you have a small dictionary with more information about your os! combining these you can create cases to meet your targets.

from bower help, save option has a capital S

-S, --save  Save installed packages into the project's bower.json dependencies

If you only need the bool result, just use the return value and ignore the out parameter.

bool successfullyParsed = int.TryParse(str, out ignoreMe);
if (successfullyParsed){
    // ...
}

Edit: Meanwhile you can also have a look at the original source code:

System.Int32.TryParse

If i want to know how something is actually implemented, i'm using ILSpy to decompile the .NET-code.

This is the result:

// int
/// <summary>Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the operation succeeded.</summary>
/// <returns>true if s was converted successfully; otherwise, false.</returns>
/// <param name="s">A string containing a number to convert. </param>
/// <param name="result">When this method returns, contains the 32-bit signed integer value equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null, is not of the correct format, or represents a number less than <see cref="F:System.Int32.MinValue"></see> or greater than <see cref="F:System.Int32.MaxValue"></see>. This parameter is passed uninitialized. </param>
/// <filterpriority>1</filterpriority>
public static bool TryParse(string s, out int result)
{
    return Number.TryParseInt32(s, NumberStyles.Integer, NumberFormatInfo.CurrentInfo, out result);
}


// System.Number
internal unsafe static bool TryParseInt32(string s, NumberStyles style, NumberFormatInfo info, out int result)
{
    byte* stackBuffer = stackalloc byte[1 * 114 / 1];
    Number.NumberBuffer numberBuffer = new Number.NumberBuffer(stackBuffer);
    result = 0;
    if (!Number.TryStringToNumber(s, style, ref numberBuffer, info, false))
    {
        return false;
    }
    if ((style & NumberStyles.AllowHexSpecifier) != NumberStyles.None)
    {
        if (!Number.HexNumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    else
    {
        if (!Number.NumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    return true;
}

And no, i cannot see any Try-Catchs on the road:

    str = ptr;

Yes, but you'll need to run it at the database level.

Right-click the database in SSMS, select "Tasks", "Generate Scripts...". As you work through, you'll get to a "Scripting Options" section. Click on "Advanced", and in the list that pops up, where it says "Types of data to script", you've got the option to select Data and/or Schema.

To roll back all migrations up to a particular version (e.g. 20181002222222), use:

rake db:migrate VERSION=20181002222222

(Note that this uses db:migrate -- not db:migrate:down as in other answers to this question.)

Assuming the specified migration version is older than the current version, this will roll back all migrations up to, but not including, the specified version.

For example, if rake db:migrate:status initially displays:

  (... some older migrations ...)
  up      20181001002039  Some migration description
  up      20181002222222  Some migration description
  up      20181003171932  Some migration description
  up      20181004211151  Some migration description
  up      20181005151403  Some migration description

Running:

rake db:migrate VERSION=20181002222222

Will result in:

  (... some older migrations ...)
  up      20181001002039  Some migration description
  up      20181002222222  Some migration description
  down    20181003171932  Some migration description
  down    20181004211151  Some migration description
  down    20181005151403  Some migration description

Queue in Java is defined as an interface and many ready-to-use implementation is present as part of JDK release. Here are some: LinkedList, Priority Queue, ArrayBlockingQueue, ConcurrentLinkedQueue, Linked Transfer Queue, Synchronous Queue etc.

SO You can create any of these class and hold it as Queue reference. for example

import java.util.LinkedList;
import java.util.Queue;

public class QueueExample {

 public static void main (String[] args) {
  Queue que = new LinkedList();
  que.add("first");
  que.offer("second");
  que.offer("third");
  System.out.println("Queue Print:: " + que);
  
  String head = que.element();
  System.out.println("Head element:: " + head);
  
  String element1 = que.poll();
  System.out.println("Removed Element:: " + element1);
  
  System.out.println("Queue Print after poll:: " + que);
  String element2 = que.remove();
  System.out.println("Removed Element:: " + element2);
  
  System.out.println("Queue Print after remove:: " + que);  
 }
}

You can also implement your own custom Queue implementing Queue interface.

I would simply do this, which literally follows what your desired logic was:

df.groupby(['org']).mean().groupby(['cluster']).mean()

My Thought,

Implicit Wait : If wait is set, it will wait for specified amount of time for each findElement/findElements call. It will throw an exception if action is not complete.

Explicit Wait : If wait is set, it will wait and move on to next step when the provided condition becomes true else it will throw an exception after waiting for specified time. Explicit wait is applicable only once wherever specified.

When you alter column datatype you need to change constraint key for every database

  alter table CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];

I just had the same problem and found this setting in config/environments/production.rb:

# Rails 4:
config.serve_static_assets = false

# Or for Rails 5:
config.public_file_server.enabled = false

Changing it to true got it working. It seems by default Rails expects you to have configured your front-end webserver to handle requests for files out of the public folder instead of proxying them to the Rails app. Perhaps you've done this for your javascript files but not your CSS stylesheets?

(See Rails 5 documentation). As noted in comments, with Rails 5 you may just set the RAILS_SERVE_STATIC_FILES environment variable, since the default setting is config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?.

Adding to ben.bourdin answer, you can at least in any HTML based application, check if the browser supports HLS in its video element:

Let´s assume that your video element ID is "myVideo", then through javascript you can use the "canPlayType" function (http://www.w3schools.com/tags/av_met_canplaytype.asp)

var videoElement = document.getElementById("myVideo");
if(videoElement.canPlayType('application/vnd.apple.mpegurl') === "probably" || videoElement.canPlayType('application/vnd.apple.mpegurl') === "maybe"){
    //Actions like playing the .m3u8 content
}
else{
    //Actions like playing another video type
}

The canPlayType function, returns:

"" when there is no support for the specified audio/video type

"maybe" when the browser might support the specified audio/video type

"probably" when it most likely supports the specified audio/video type (you can use just this value in the validation to be more sure that your browser supports the specified type)

Hope this help :)

Best regards!

You can try the some thing like the below LINQ snippet.

string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");

    var query = from line in allLines
                let data = line.Split(',')
                select new
                {
                    Device = data[0],
                    SignalStrength = data[1],
                    Location = data[2], 
                    Time = data[3],
                    Age = Convert.ToInt16(data[4])
                };

UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx

As far as I know List<T> implements IEnumerable<T>. It means that you do not have to convert or cast anything.

Convert.ToInt32() takes uint as a value.

You can use a node.js extension to provide bindings for your C++ code. Here is one tutorial that covers that:

http://syskall.com/how-to-write-your-own-native-nodejs-extension

Just used the Nathan's solution and it works fine. I needed to convert ISO-8859-1 to Unicode:

string isocontent = Encoding.GetEncoding("ISO-8859-1").GetString(fileContent, 0, fileContent.Length);
byte[] isobytes = Encoding.GetEncoding("ISO-8859-1").GetBytes(isocontent);
byte[] ubytes = Encoding.Convert(Encoding.GetEncoding("ISO-8859-1"), Encoding.Unicode, isobytes);
return Encoding.Unicode.GetString(ubytes, 0, ubytes.Length);

You forgot to seek:

str.CopyTo(data);
data.Seek(0, SeekOrigin.Begin); // <-- missing line
byte[] buf = new byte[data.Length];
data.Read(buf, 0, buf.Length);

This looks like a more promising solution: IntelliJ Android UI Designer.

http://blogs.jetbrains.com/idea/2012/06/android-ui-designer-coming-in-intellij-idea-12/

The underlying type of a variadic method function(Object... args) is function(Object[] args). Sun added varargs in this manner to preserve backwards compatibility.

So you should just be able to prepend extraVar to args and call String.format(format, args).

You need to provide a way of accessing the member variables so you can pass in a mock (the most common ways would be a setter method or a constructor which takes a parameter).

If your code doesn't provide a way of doing this, it's incorrectly factored for TDD (Test Driven Development).

I had the same problem. For me the solution is to delete the remote file and let rsync create again.

Cross-Origin Read Blocking (CORB), an algorithm by which dubious cross-origin resource loads may be identified and blocked by web browsers before they reach the web page..It is designed to prevent the browser from delivering certain cross-origin network responses to a web page.

First Make sure these resources are served with a correct "Content-Type", i.e, for JSON MIME type - "text/json", "application/json", HTML MIME type - "text/html".

Second: set mode to cors i.e, mode:cors

The fetch would look something like this

 fetch("https://example.com/api/request", {
            method: 'POST',
            body: JSON.stringify(data),
            mode: 'cors',
            headers: {
                'Content-Type': 'application/json',
                "Accept": 'application/json',
            }
        })
    .then((data) => data.json())
    .then((resp) => console.log(resp))
    .catch((err) => console.log(err))

As a checkbox click = a checkbox change the following will also work:

<CheckBox Click="CheckBox_Click" />

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
    // ... do some stuff
}

It has the additional advantage of working when IsThreeState="True" whereas just handling Checked and Unchecked does not.

The convention for out of range in JavaScript is using RangeError. To check the type use if / else + instanceof starting at the most specific to the most generic

try {
    throw new RangeError();
}
catch (e){
    if (e instanceof RangeError){
        console.log('out of range');
    } else { 
        throw; 
    }
}

Primitives can be converted to objects with @() expression. So the shortest way is to transform int to NSNumber and pick up string representation with stringValue method:

NSString *strValue = [@(myInt) stringValue];

or

NSString *strValue = @(myInt).stringValue;

One simple approach you could take is to compare the length of the original string with that of the string to have whitespaces replaced with nothing. For example:

function hasWhiteSpaces(string) {
    if (string.length == string.replace(" ", "").length) {return false}
    return true
}

No, sadly:

The Excel 2010 client application does not support co-authoring workbooks in SharePoint Server 2010. However, the Excel client application does support non-real-time co-authoring workbooks stored locally or on network (UNC) paths by using the Shared Workbook feature. Co-authoring workbooks in SharePoint is supported by using the Microsoft Excel Web App, included with Office Web Apps

From Co-authoring overview (SharePoint Server 2010)

...and not for SharePoint 2013 either. Though it works for pretty much all other Office documents. Go figure.

Simply go here: https://dev.twitter.com/apps/new Make sure you have logged in with your Twitter account - then create - even if your just entering random (Test) Content - create your app - afterwards you will receive all the data you require :)

you can make a function like this

function translateTo($language, $word) {  
   define('defaultLang','english');  
   if (isset($lang[$language][$word]) == FALSE)  
      return $lang[$language][$word];  
   else  
      return $lang[defaultLang][$word];  
}

First, the problem of the missing prefix.

If you consume something in your layout file that comes from a third party, you may need to consume its prefix as well, something like "droidfu:" which occurs in several places in the XML construct below:

<com.github.droidfu.widgets.WebImageView android:id="@+id/webimage"
          android:layout_width="75dip"
          android:layout_height="75dip"
          android:background="#CCC"
          droidfu:autoLoad="true"
          droidfu:imageUrl="http://www.android.com/images/opensourceprojec.gif"
          droidfu:progressDrawable="..."
          />

This comes out of the JAR, but you'll also need to add the new "xmlns:droidfu"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:droidfu="http://github.com/droidfu/schema"
      ...>

or you get the unbound prefix error. For me, this was a failure to copy and paste all of the supplied example from the third-party library's pages.

It is simpler just to run an exact copy like below to put the copy in as the last sheet

Sub Test()
Dim ws1 As Worksheet
Set ws1 = ThisWorkbook.Worksheets("Master")
ws1.Copy ThisWorkbook.Sheets(Sheets.Count)
End Sub

Here is another apporach.

You can accomplish it in this way too:

.parent{
  display: flex;
  flex-wrap: wrap;
}

.child{
  width: 25%;
  box-sizing: border-box;
}

<input type="radio" name="user-radio" id="" value="Guest" /> 

I think there is a simpler way to make excel wait till the refresh is done, without having to set the Background Query property to False. Why mess with people's preferences right?

Excel 2010 (and later) has this method called CalculateUntilAsyncQueriesDone and all you have to do it call it after you have called the RefreshAll method. Excel will wait till the calculation is complete.

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone

I usually put these things together to do a master full calculate without interruption, before sending my models to others. Something like this:

ThisWorkbook.RefreshAll
Application.CalculateUntilAsyncQueriesDone
Application.CalculateFullRebuild
Application.CalculateUntilAsyncQueriesDone

If you look at the line which is causing the error, you'll see this:

from numpy._distributor_init import NUMPY_MKL  # requires numpy+mkl

This line comment states the dependency as numpy+mkl (numpy with Intel Math Kernel Library). This means that you've installed the numpy by pip, but the scipy was installed by precompiled archive, which expects numpy+mkl.

This problem can be easy solved by installation for numpy+mkl from whl file from here.

My problem was solved by creating a Windows user without an accent or special characters and reinstalling android studio on that user. Another change is to change the environment variables:

Left Click in My Computer > Advanced System Settings> Advanced > Environment Variables

ANDROID_HOME = c:\my_sdk_path

ANDROID_SDK_ROOT = c:\my_sdk_path

JAVA_HOME = c:\program files\Java\yourJavaPath

• the default path of SDK is c:\users\youruser\AppData\LocalAndroid\sdk

Add in Path Variable the values:

1. %ANDROID_HOME%\platform-tools

2. %ANDROID_HOME%\tools

After changes, restart windows and try again!

Assuming MySQL (EDIT: posted before the SQL variant was supplied):

ALTER TABLE myTable ADD myNewColumn VARCHAR(255) AFTER myOtherColumn

The AFTER keyword tells MySQL where to place the new column. You can also use FIRST to flag the new column as the first column in the table.

I believe that all the previously proposed solutions (apart from those that require specific implementations) result in the comments being included in the output HTML, even if they are not displayed.

If you want a comment that is strictly for yourself (readers of the converted document should not be able to see it, even with "view source") you could (ab)use the link labels (for use with reference style links) that are available in the core Markdown specification:

http://daringfireball.net/projects/markdown/syntax#link

That is:

[comment]: <> (This is a comment, it will not be included)
[comment]: <> (in  the output file unless you use it in)
[comment]: <> (a reference style link.)

Or you could go further:

[//]: <> (This is also a comment.)

To improve platform compatibility (and to save one keystroke) it is also possible to use # (which is a legitimate hyperlink target) instead of <>:

[//]: # (This may be the most platform independent comment)

For maximum portability it is important to insert a blank line before and after this type of comments, because some Markdown parsers do not work correctly when definitions brush up against regular text. The most recent research with Babelmark shows that blank lines before and after are both important. Some parsers will output the comment if there is no blank line before, and some parsers will exclude the following line if there is no blank line after.

In general, this approach should work with most Markdown parsers, since it's part of the core specification. (even if the behavior when multiple links are defined, or when a link is defined but never used, is not strictly specified).

x//1

The // operator returns the floor of the division. Since dividing by 1 doesn't change your number, this is equivalent to floor but no import is needed. Notes:

1. This returns a float
2. This rounds towards -8

Crazy. I know.

Tried all options here. Restarting, cleaning, manually checking in generated DLLs (this is invaluable to understanding if it's actually yourself that messed up).

I got it to work by setting the Verbosity of MSBuild to "Detailed" in Options.

This is just how Response.Redirect(url, true) works. It throws the ThreadAbortException to abort the thread. Just ignore that exception. (I presume it is some global error handler/logger where you see it?)

There is a limitation in SQL Server (up till 2008 R2) that varchar(MAX) and nvarchar(MAX) (and several other types like text, ntext ) cannot be used in indices. You have 2 options:
1. Set a limited size on the key field ex. nvarchar(100)
2. Create a check constraint that compares the value with all the keys in the table. The condition is:

([dbo].[CheckKey]([key])=(1))

and [dbo].[CheckKey] is a scalar function defined as:

CREATE FUNCTION [dbo].[CheckKey]
(
    @key nvarchar(max)
)
RETURNS bit
AS
BEGIN
    declare @res bit
    if exists(select * from key_value where [key] = @key)
        set @res = 0
    else
        set @res = 1

    return @res
END

But note that a native index is more performant than a check constraint so unless you really can't specify a length, don't use the check constraint.

The pattern below, when used with java.util.regex.Matcher, will match any string between double quotes without affecting occurrences of double quotes inside the string:

Use button.layer.cornerRadius, button.layer.borderColor and button.layer.borderWidth. Note that borderColor requires a CGColor, so you could say (Swift 3/4):

button.backgroundColor = .clear
button.layer.cornerRadius = 5
button.layer.borderWidth = 1
button.layer.borderColor = UIColor.black.cgColor

Add your own class, ex: <div class="sidebar right"></div>, with the CSS as

.sidebar.right { 
    float:right
} 

I'm not sure exactly what you want, but I think it's along the lines of:

SELECT `Item`, `qty`-`BAL_QTY` as `qty` FROM ((SELECT Item, SUM(`QTY`) as qty FROM `master_table` GROUP BY `ITEM`) as A NATURAL JOIN `stock_table`) as B

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

In TortoiseSVN, you can also Shift + right-click to get a menu that includes "Delete (keep local)".

Here is a function generalizing previous approaches, creating a grid of images in PIL:

from PIL import Image
import numpy as np

def pil_grid(images, max_horiz=np.iinfo(int).max):
    n_images = len(images)
    n_horiz = min(n_images, max_horiz)
    h_sizes, v_sizes = [0] * n_horiz, [0] * (n_images // n_horiz)
    for i, im in enumerate(images):
        h, v = i % n_horiz, i // n_horiz
        h_sizes[h] = max(h_sizes[h], im.size[0])
        v_sizes[v] = max(v_sizes[v], im.size[1])
    h_sizes, v_sizes = np.cumsum([0] + h_sizes), np.cumsum([0] + v_sizes)
    im_grid = Image.new('RGB', (h_sizes[-1], v_sizes[-1]), color='white')
    for i, im in enumerate(images):
        im_grid.paste(im, (h_sizes[i % n_horiz], v_sizes[i // n_horiz]))
    return im_grid

It will shrink each row and columns of the grid to the minimum. You can have only a row by using pil_grid(images), or only a column by using pil_grid(images, 1).

One benefit of using PIL over numpy-array based solutions is that you can deal with images structured differently (like grayscale or palette-based images).

Example outputs

def dummy(w, h):
    "Produces a dummy PIL image of given dimensions"
    from PIL import ImageDraw
    im = Image.new('RGB', (w, h), color=tuple((np.random.rand(3) * 255).astype(np.uint8)))
    draw = ImageDraw.Draw(im)
    points = [(i, j) for i in (0, im.size[0]) for j in (0, im.size[1])]
    for i in range(len(points) - 1):
        for j in range(i+1, len(points)):
            draw.line(points[i] + points[j], fill='black', width=2)
    return im

dummy_images = [dummy(20 + np.random.randint(30), 20 + np.random.randint(30)) for _ in range(10)]

pil_grid(dummy_images):

pil_grid(dummy_images, 3):

pil_grid(dummy_images, 1):

I tried the example here of the Mvc Controls Toolkit grid. It appears a quite powerful and easy to use grid. The tutorial not only explain how to use the grid but also how to do paging, organize a view model and data annotations. It is worth to read it.

Add the below to the build.gradle project module:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Maybe a bit late, but hope it hellps:

@echo off 

if %ERRORLEVEL% == 0 (

If you want to change the permissions of an existing file, use chmod (change mode):

$itWorked = chmod ("/yourdir/yourfile", 0777);

If you want all new files to have certain permissions, you need to look into setting your umode. This is a process setting that applies a default modification to standard modes.

It is a subtractive one. By that, I mean a umode of 022 will give you a default permission of 755 (777 - 022 = 755).

But you should think very carefully about both these options. Files created with that mode will be totally unprotected from changes.

If you're dealing with files above 2 GB, you'll find that the above methods fail.

It's much easier just to hand the stream off to MD5 and allow that to chunk your file for you:

private byte[] computeFileHash(string filename)
{
    MD5 md5 = MD5.Create();
    using (FileStream fs = new FileStream(filename, FileMode.Open))
    {
        byte[] hash = md5.ComputeHash(fs);
        return hash;
    }
}

Small +1 to kshark27's answer to make it dynamic:

#include <QTime>

void delay( int millisecondsToWait )
{
    QTime dieTime = QTime::currentTime().addMSecs( millisecondsToWait );
    while( QTime::currentTime() < dieTime )
    {
        QCoreApplication::processEvents( QEventLoop::AllEvents, 100 );
    }
}

In theory like so:

# BOLD
$ echo -e "\033[1mThis is a BOLD line\033[0m"
This is a BOLD line

# Using tput
tput bold 
echo "This" #BOLD
tput sgr0 #Reset text attributes to normal without clear.
echo "This" #NORMAL

# UNDERLINE
$ echo -e "\033[4mThis is a underlined line.\033[0m"
This is a underlined line. 

But in practice it may be interpreted as "high intensity" color instead.

There are multiple ways

return \Response::json(['hello' => $value], STATUS_CODE);

return response()->json(['hello' => $value], STATUS_CODE);

where STATUS_CODE is your HTTP status code you want to send. Both are identical.

if you are using Eloquent model, then simple return will also be auto converted in JSON by default like,

return User::all();

There is no support for MapFragment, Android team says is working on it since Android 3.0. Here more information about the issue But what you can do it by creating a Fragment that returns a MapActivity. Here is a code example. Thanks to inazaruk:

How it works :

• MainFragmentActivity is the activity that extends FragmentActivity and hosts two MapFragments.
• MyMapActivity extends MapActivity and has MapView.
• LocalActivityManagerFragment hosts LocalActivityManager.
• MyMapFragment extends LocalActivityManagerFragment and with help of TabHost creates internal instance of MyMapActivity.

If you have any doubt please let me know

OR you could just use javac file1.java and then also use javac file2.java afterwards.

You have to add the row explicitly to the table

table.Rows.Add(row);

They are viewport meta tags, and is most applicable on mobile browsers.

width=device-width

This means, we are telling to the browser “my website adapts to your device width”.

initial-scale

This defines the scale of the website, This parameter sets the initial zoom level, which means 1 CSS pixel is equal to 1 viewport pixel. This parameter help when you're changing orientation, or preventing default zooming. Without this parameter, responsive site won't work.

maximum-scale

Maximum-scale defines the maximum zoom. When you access the website, top priority is maximum-scale=1, and it won’t allow the user to zoom.

minimum-scale

Minimum-scale defines the minimum zoom. This works the same as above, but it defines the minimum scale. This is useful, when maximum-scale is large, and you want to set minimum-scale.

user-scalable

User-scalable assigned to 1.0 means the website is allowing the user to zoom in or zoom out.

But if you assign it to user-scalable=no, it means the website is not allowing the user to zoom in or zoom out.

Use simple ssh-keyscan hostname to find if key(s) exists on both sites:

ssh-keyscan rc1.localdomain
[or@rc2 ~]$ ssh-keyscan rc1
# rc1 SSH-2.0-OpenSSH_5.3
rc1 ssh-rsa AAAAB3NzaC1yc2EAAAABI.......==

ssh-keyscan rc2.localdomain
[or@rc2 ~]$ ssh-keyscan rc2
# rac2 SSH-2.0-OpenSSH_5.3
rac2 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAys7kG6pNiC.......==

You can get the column value in VB.net

Dim row As DataRow = fooTable.Rows(0)
Dim temp = Convert.ToString(row("ColumnName"))

And in C# you can use Jimmy's Answer, just be careful while converting it to ToString(). It can throw null exception if the data is null instead Use Convert.ToString(your_expression) to avoid null exception reference

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

atob -- > converts ascii to binary

btoa -- > converts binary to ascii

Ext.application({
    name: 'Fiddle',

    launch: function () {
        var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));

        Ext.create("Ext.panel.Panel", {
            title: "Test",
            renderTo: Ext.getBody(),
            height: 400,
            items: [{
                xtype: 'image',
                width: 100,
                height: 100,
                src: srcBase64
            }]
        })
    }
});

Interestingly, it seems that in Windows Embedded Compact 7, you cannot specify a title string. The first parameter has to be the command or program.

I've been using matlab for many years in my research. It's great for linear algebra and has a large set of well-written toolboxes. The most recent versions are starting to push it into being closer to a general-purpose language (better optimizers, a much better object model, richer scoping rules, etc.).

This past summer, I had a job where I used Python + numpy instead of Matlab. I enjoyed the change of pace. It's a "real" language (and all that entails), and it has some great numeric features like broadcasting arrays. I also really like the ipython environment.

Here are some things that I prefer about Matlab:

• consistency: MathWorks has spent a lot of effort making the toolboxes look and work like each other. They haven't done a perfect job, but it's one of the best I've seen for a codebase that's decades old.
• documentation: I find it very frustrating to figure out some things in numpy and/or python because the documentation quality is spotty: some things are documented very well, some not at all. It's often most frustrating when I see things that appear to mimic Matlab, but don't quite work the same. Being able to grab the source is invaluable (to be fair, most of the Matlab toolboxes ship with source too)
• compactness: for what I do, Matlab's syntax is often more compact (but not always)
• momentum: I have too much Matlab code to change now

If I didn't have such a large existing codebase, I'd seriously consider switching to Python + numpy.

After a lot of trial and error, followed by a stagnant period while I waited for an opportunity to speak with our server guys, I finally had a chance to discuss the problem with them and asked them if they wouldn't mind switching our Sharepoint authentication over to Kerberos.

To my surprise, they said this wouldn't be a problem and was in fact easy to do. They enabled Kerberos and I modified my app.config as follows:

<security mode="Transport">
    <transport clientCredentialType="Windows" />
</security>

For reference, my full serviceModel entry in my app.config looks like this:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="TestServerReference" closeTimeout="00:01:00" openTimeout="00:01:00"
             receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
             bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
             maxBufferSize="2000000" maxBufferPoolSize="2000000" maxReceivedMessageSize="2000000"
             messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                 maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                <security mode="Transport">
                    <transport clientCredentialType="Windows" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="https://path/to/site/_vti_bin/Lists.asmx"
         binding="basicHttpBinding" bindingConfiguration="TestServerReference"
         contract="TestServerReference.ListsSoap" name="TestServerReference" />
    </client>
</system.serviceModel>

After this, everything worked like a charm. I can now (finally!) utilize Sharepoint Web Services. So, if anyone else out there can't get their Sharepoint Web Services to work with NTLM, see if you can convince the sysadmins to switch over to Kerberos.

This is the solution i found.

https://github.com/aspnet/EntityFramework.Docs/blob/master/entity-framework/core/miscellaneous/configuring-dbcontext.md

Configure DBContext via AddDbContext

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext<BloggingContext>(options => options.UseSqlite("Data Source=blog.db"));
}

Add new constructor to your DBContext class

public class BloggingContext : DbContext
{
    public BloggingContext(DbContextOptions<BloggingContext> options)
      :base(options)
    { }

    public DbSet<Blog> Blogs { get; set; }
}

Inject context to your controllers

public class MyController
{
    private readonly BloggingContext _context;

    public MyController(BloggingContext context)
    {
      _context = context;
    }

    ...
}

To elaborate on Pascal: Do you understand how a HashMap works? You have some number of slots in your hash table. The hash value for each key is found, and then mapped to an entry in the table. If two hash values map to the same entry -- a "hash collision" -- HashMap builds a linked list.

Hash collisions can kill the performance of a hash map. In the extreme case, if all your keys have the same hash code, or if they have different hash codes but they all map to the same slot, then your hash map turns into a linked list.

So if you're seeing performance problems, the first thing I'd check is: Am I getting a random-looking distribution of hash codes? If not, you need a better hash function. Well, "better" in this case may mean "better for my particular set of data". Like, suppose you were working with strings, and you took the length of the string for the hash value. (Not how Java's String.hashCode works, but I'm just making up a simple example.) If your strings have widely varying lengths, from 1 to 10,000, and are fairly evenly distributed across that range, that this could be a very good hash function. But if your strings are all 1 or 2 characters, this would be a very bad hash function.

Edit: I should add: Every time you add a new entry, HashMap checks if this is a duplicate. When there's a hash collision, it has to compare the incoming key against every key that mapped to that slot. So in the worst case where everything hashes to a single slot, the second key is compared to the first key, the third key is compared to #1 and #2, the fourth key is compared to #1, #2, and #3, etc. By the time you get to key #1 million, you've done over a trillion compares.

@Oscar: Umm, I don't see how that's a "not really". It's more like a "let me clarify". But yes, it's true that if you make a new entry with the same key as an existing entry, that this overwrites the first entry. That's what I meant when I talked about looking for duplicates in the last paragraph: Whenever a key hashes to the same slot, HashMap must check if it's a duplicate of an existing key, or if they are just in the same slot by coincidence of the hash function. I don't know that that's the "whole point" of a HashMap: I would say that the "whole point" is that you can retrieve elements by key quickly.

But anyway, that doesn't affect the "whole point" that I was trying to make: When you have two keys -- yes, different keys, not the same key showing up again -- that map to the same slot in the table, HashMap builds a linked list. Then, because it has to check each new key to see if it is in fact a duplicate of an existing key, each attempt to add a new entry that maps to this same slot must chase the linked list examining each existing entry to see if this is a duplicate of a previously-seen key, or if it is a new key.

Update long after the original post

I just got an up-vote on this answer 6 years after posting which led me to re-read the question.

The hash function given in the question is not a good hash for 26 million entries.

It adds together a[0]+a[1] and b[0]+b[1]+b[2]. He says values of each byte range from 0 to 51, so that gives only (51*2+1)*(51*3+1)=15,862 possible hash values. With 26 million entries, this means an average of about 1639 entries per hash value. That is lots and lots of collisions, requiring lots and lots of sequential searches through linked lists.

The OP says that different orders within array a and array b should be considered equal, i.e. [[1,2],[3,4,5]].equals([[2,1],[5,3,4]]), and so to fulfill the contract they must have equal hash codes. Okay. Still, there are a lot more than 15,000 possible values. His second proposed hash function is much better, giving a broader range.

Though as someone else commented, it seems inappropriate for a hash function to change other data. It would make more sense to "normalize" the object when it is created, or to have the hash function work from copies of the arrays. Also, using a loop to calculate constants every time through the function is inefficient. As there are only four values here, I would have either written

return a[0]+a[1]*52+b[0]*52*52+b[1]*52*52*52+b[2]*52*52*52*52;

which would cause the compiler to perform the calculation once at compile time; or have 4 static constants defined in the class.

Also, the first draft at a hash function has several calculations that do nothing to add to the range of outputs. Note he first sets hash =503 than multiplies by 5381 before even considering values from the class. So ... in effect he adds 503*5381 to every value. What does this accomplish? Adding a constant to every hash value just burns cpu cycles without accomplishing anything useful. Lesson here: Adding complexity to a hash function is not the goal. The goal is to get a broad range of different values, not just to add complexity for the sake of complexity.

OK so I think i know the issue you're having.

Basically, because Composer can't see the migration files you are creating, you are having to run the dump-autoload command which won't download anything new, but looks for all of the classes it needs to include again. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php), and this is why your migration is working after you run that command.

How to fix it (possibly) You need to add some extra information to your composer.json file.

"autoload": {
    "classmap": [
        "PATH TO YOUR MIGRATIONS FOLDER"
    ],
}

You need to add the path to your migrations folder to the classmap array. Then run the following three commands...

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

This will clear the current compiled files, update the classes it needs and then write them back out so you don't have to do it again.

Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticable).

Hope you can manage to get this sorted, as its very annoying indeed :(

A very easy kind of event you can wait for is the ManualResetEvent, and even better, the ManualResetEventSlim.

They have a WaitOne() method that does exactly that. You can wait forever, or set a timeout, or a "cancellation token" which is a way for you to decide to stop waiting for the event (if you want to cancel your work, or your app is asked to exit).

You fire them calling Set().

Here is the doc.

You can also perform Implicit Type Conversions with template literals. Example:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

Use java.beans.XMLDecoder, part of core Java SE since 1.4.

XMLDecoder input = new XMLDecoder(new FileInputStream("some/path.xml"));
MyConfig config = (MyConfig) input.readObject();
input.close();

It's easy to write the configuration files by hand, or use the corresponding XMLEncoder with some setup to write new objects at run-time.

In this case you want to "calculate" a pixel value depending of an object property.

I would define a function in the controller that calculates the pixel values.

In the controller:

$scope.GetHeight = function(aspect) {
   if(bla bla bla) return 270;
   return 360;
}

Then in your template you just write:

element height="{{ GetHeight(aspect) }}px "

Use System.Net.WebClient.DownloadFile:

string remoteUri = "http://www.contoso.com/library/homepage/images/";
string fileName = "ms-banner.gif", myStringWebResource = null;

// Create a new WebClient instance.
using (WebClient myWebClient = new WebClient())
{
    myStringWebResource = remoteUri + fileName;
    // Download the Web resource and save it into the current filesystem folder.
    myWebClient.DownloadFile(myStringWebResource, fileName);        
}

The problem is in the line,

int([x[age1]])

What you want is

x = int(age1)

You also need to convert the int to a string for the output...

print "Hi, " + name1+ " you will be 21 in: " + str(twentyone) + " years."

The complete script looks like,

name1 = raw_input("What's your name? ")
age1 = raw_input ("how old are you? ")
x = 0
x = int(age1)
twentyone = 21 - x
print "Hi, " + name1+ " you will be 21 in: " + str(twentyone) + " years."

• Make sure we are not editing any of the default sshd_config properties to skip the error

• Host Verification Failed - Definitely a missing entry of hostname in known_hosts file

• Login to the server where the process is failing and do the following:

  1. Sudo to the user running the process

  2. ssh-copy-id destinationuser@destinationhostname

  3. It will prompt like this for the first time, say yes and it will also ask password for the first time:

     The authenticity of host 'sample.org (205.214.640.91)' can't be established.
     RSA key fingerprint is 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40.
     Are you sure you want to continue connecting (yes/no)? *yes*
     

     Password prompt ? give password

  4. Now from the server where process is running, do ssh destinationuser@destinationhostname. It should login without a password.

     Note: Do not change the default permissions of files in the user's .ssh directory, you will end up with different issues

I... don't think so. You can redirect the subdomain (such as blah.something.com) to point to something.com:25566, but I don't think you can actually set up the subdomain to be on a different port like that. I could be wrong, but it'd probably be easier to use a simple .htaccess or something to check %{HTTP_HOST} and redirect according to the subdomain.

Check here DEMO http://jsfiddle.net/yeyene/Uhm2J/

function getData() {
    $.getJSON('Get/GetData?no=1', function (responseText) {
        //Load some data from the server
    })
};

$(window).scroll(function() {
   if($(window).scrollTop() + $(window).height() == $(document).height()) {
       alert("bottom!");
       // getData();
   }
});

Casting is necessary to tell that you are calling a child and not a parent method. So it's ever downward. However if the method is already defined in the parent class and overriden in the child class, you don't any cast. Here an example:

class Parent{
   void method(){ System.out.print("this is the parent"); }
}

class Child extends Parent{
   @override
   void method(){ System.out.print("this is the child"); }
}
...
Parent o = new Child();
o.method();
((Child)o).method();  

The two method call will both print : "this is the child".

stringstream.str() returns a temporary string object that's destroyed at the end of the full expression. If you get a pointer to a C string from that (stringstream.str().c_str()), it will point to a string which is deleted where the statement ends. That's why your code prints garbage.

You could copy that temporary string object to some other string object and take the C string from that one:

const std::string tmp = stringstream.str();
const char* cstr = tmp.c_str();

Note that I made the temporary string const, because any changes to it might cause it to re-allocate and thus render cstr invalid. It is therefor safer to not to store the result of the call to str() at all and use cstr only until the end of the full expression:

use_c_str( stringstream.str().c_str() );

Of course, the latter might not be easy and copying might be too expensive. What you can do instead is to bind the temporary to a const reference. This will extend its lifetime to the lifetime of the reference:

{
  const std::string& tmp = stringstream.str();   
  const char* cstr = tmp.c_str();
}

IMO that's the best solution. Unfortunately it's not very well known.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

As stated in the Laravel manual, you may roll back specific number of migrations using the --step option

php artisan migrate:rollback --step=5

Bundle extras = getIntent().getExtras();
Set<String> ks = extras.keySet();
Iterator<String> iterator = ks.iterator();
while (iterator.hasNext()) {
    Log.d("KEY", iterator.next());
}

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

Even though you've got your answer, for those that find this question, it is also possible to open an Excel spreadsheet as a JET data store. Borrowing the connection string from a project I've used it on, it will look kinda like this:

strExcelConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & objFile.Path & ";Extended Properties=""Excel 8.0;HDR=Yes"""
strSQL = "SELECT * FROM [RegistrationList$] ORDER BY DateToRegister DESC"

Note that "RegistrationList" is the name of the tab in the workbook. There are a few tutorials floating around on the web with the particulars of what you can and can't do accessing a sheet this way.

Just thought I'd add. :)
