Its due to PHP that has a file size restriction for uploads.

If you have terminal/shell access then the above answers @Kyotoweb will work.

one way to get it done is that you create an .htaccess/ini file file to change PHP settings to get the sql file uploaded through PHPmyAdmin.

php_value upload_max_filesize 120M //file size
php_value post_max_size 120M
php_value max_execution_time 200
php_value max_input_time 200

Note you should remove this file after upload.

I wish #pragma once (or something like it) had been in the standard. Include guards aren't a real big deal (but they do seem to be a little difficult to explain to people learning the language), but it seems like a minor annoyance that could have been avoided.

In fact, since 99.98% of the time, the #pragma once behavior is the desired behavior, it would have been nice if preventing multiple inclusion of a header was automatically handled by the compiler, with a #pragma or something to allow double including.

But we have what we have (except that you might not have #pragma once).

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

Try to execute

mvn -U clean

A cleaner way to gain higher control might be to package the retry stuff into a function and make that function retriable using a decorator and whitelist the exceptions.

I have created the same here: http://www.praddy.in/retry-decorator-whitelisted-exceptions/

Reproducing the code in that link :

def retry(exceptions, delay=0, times=2):
"""
A decorator for retrying a function call with a specified delay in case of a set of exceptions

:param exceptions:  A tuple of all exceptions that need to be caught for retry
                                    e.g. retry(exception_list = (Timeout, Readtimeout))
:param delay: Amount of delay (seconds) needed between successive retries.
:param times: no of times the function should be retried

From MSDN:

The WPF Font Cache service shares font data between WPF applications. The first WPF application you run starts this service if the service is not already running. If you are using Windows Vista, you can set the "Windows Presentation Foundation (WPF) Font Cache 3.0.0.0" service from "Manual" (the default) to "Automatic (Delayed Start)" to reduce the initial start-up time of WPF applications.

There's no harm in disabling it, but WPF apps tend to start faster and load fonts faster with it running.
It is supposed to be a performance optimization. The fact that it is not in your case makes me suspect that perhaps your font cache is corrupted. To clear it, follow these steps:

1. Stop the WPF Font Cache 4.0 service.
2. Delete all of the WPFFontCache_v0400* files. In Windows XP, you'll find them in your C:\Documents and Settings\LocalService\Local Settings\Application Data\ folder.
3. Start the service again.

This was driving me crazy, but it seems that aularon's edit was missing the colon after "Vary". So changing "Vary Accept-Encoding" to "Vary: Accept-Encoding" fixed the issue for me.

I would have commented below the post, but it doesn't seem like it will let me.

Anyhow, I hope this saves someone the same trouble I was having.

You can do this:

app-routing-modules.ts:

import { NgModule                  }    from '@angular/core';
import { RouterModule, Routes      }    from '@angular/router';
import { PowerBoosterComponent     }    from './component/power-booster.component';


export const routes: Routes = [
  { path:  'pipeexamples',component: PowerBoosterComponent, 
data:{  name:'shubham' } },
    ];
    @NgModule({
      imports: [ RouterModule.forRoot(routes) ],
      exports: [ RouterModule ]
    })
    export class AppRoutingModule {}

In this above route, I want to send data via a pipeexamples path to PowerBoosterComponent.So now I can receive this data in PowerBoosterComponent like this:

power-booster-component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';

@Component({
  selector: 'power-booster',
  template: `
    <h2>Power Booster</h2>`
})

export class PowerBoosterComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {
    //this.route.snapshot.data['name']
    console.log("Data via params: ",this.route.snapshot.data['name']);
  }
}

So you can get the data by this.route.snapshot.data['name'].

Say your model is 'Shop'

class Shop(models.Model):
    street = models.CharField(max_length=150)
    city = models.CharField(max_length=150)

    # some of your models may have explicit ordering
    class Meta:
        ordering = ('city')

Since you may have the Meta class ordering attribute set, you can use order_by() without parameters to clear any ordering when using distinct(). See the documentation under order_by()

If you don’t want any ordering to be applied to a query, not even the default ordering, call order_by() with no parameters.

and distinct() in the note where it discusses issues with using distinct() with ordering.

To query your DB, you just have to call:

models.Shop.objects.order_by().values('city').distinct()

It returns a dictionnary

or

models.Shop.objects.order_by().values_list('city').distinct()

This one returns a ValuesListQuerySet which you can cast to a list. You can also add flat=True to values_list to flatten the results.

See also: Get distinct values of Queryset by field

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

i got the same error, but with no relation to Hibernate. I got scared here from all frightening suggestions, which i guess relevant in case of Hibernate and lazy loading... However, in my case i got the error since in an inner class i had no getters/setters, so the BeanSerializer could not serialize the data...

Adding getters & setters resolved the problem.

Downgrading the iOS development Target from 12.1 to 12 fix the issue for me as I don't have a dev team configured.

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

You can do :

try : 
   string_integer = int(string)
except ValueError  :
   print("This string doesn't contain an integer")

I fixed this. When you add the migration, in the Up() method there will be a line like this:

.ForeignKey("dbo.Members", t => t.MemberId, cascadeDelete:True)

If you just delete the cascadeDelete from the end it will work.

There seems to be no way to do this in PowerShell. All of the previous answers are not correct, because they do not behave the way Write-Output behaves but more like Write-Host which doesn't have this problem anyway.

The closes solution seems to use Write-Host with the -NoNewLine parameter. You can not pipe this which is a problem generally, but there is a way to override this function as described in Write-Host => Export to a file, so you can easily make it accept the parameter for an output file. This is still far from a good solution. With Start-Transcript this is more usable, but that cmdlet has problems with native applications.

Write-Outputsimply can't do what you need in a general context.

All objects in python are implemented via references so the distinction between objects and pointers to objects does not exist in source code.

The python equivalent of NULL is called None (good info here). As all objects in python are implemented via references, you can re-write your struct to look like this:

class Node:
    def __init__(self): #object initializer to set attributes (fields)
        self.val = 0
        self.right = None
        self.left = None

And then it works pretty much like you would expect:

node = Node()
node.val = some_val #always use . as everything is a reference and -> is not used
node.left = Node()

Note that unlike in NULL in C, None is not a "pointer to nowhere": it is actually the only instance of class NoneType. Therefore, as None is a regular object, you can test for it just like any other object:

if node.left == None:
   print("The left node is None/Null.")

Although since None is a singleton instance, it is considered more idiomatic to use is and compare for reference equality:

if node.left is None:
   print("The left node is None/Null.")

If you start eclipse using oracle java, then eclipse might fail in finding native libraries like SWT or SVN libraries. The SWT-JNI libraries are located in /usr/lib/jni/ and the SVN-JNI libraries are located in /usr/lib/x86_64-linux-gnu/jni/.

Instead of starting eclipse with the command

eclipse

you can use the command

env LD_LIBRARY_PATH=/usr/lib/jni/:/usr/lib/x86_64-linux-gnu/jni/:$LD_LIBRARY_PATH eclipse

to pass the environment variable LD_LIBRARY_PATH to eclipse. Eclipse will find the native libraries and will run properly.

Swift 3 version

Swift 3 utilizes new DispatchQueue class to manage queues and threads. To run something on the background thread you would use:

let backgroundQueue = DispatchQueue(label: "com.app.queue", qos: .background)
backgroundQueue.async {
    print("Run on background thread")
}

Or if you want something in two lines of code:

DispatchQueue.global(qos: .background).async {
    print("Run on background thread")

    DispatchQueue.main.async {
        print("We finished that.")
        // only back on the main thread, may you access UI:
        label.text = "Done."
    }
}

You can also get some in-depth info about GDC in Swift 3 in this tutorial.

var model = {"Id": "xx", "Name":"Ravi"};
$.ajax({    url: 'test/set',
                        type: "POST",
                        data: model,
                        success: function (res) {
                            if (res != null) {
                                alert("done.");
                            }
                        },
                        error: function (res) {

                        }
                    });

queryForMap is appropriate if you want to get a single row. You are selecting without a where clause, so you probably want to queryForList. The error is probably indicative of the fact that queryForMap wants one row, but you query is retrieving many rows.

Check out the docs. There is a queryForList that takes just sql; the return type is a

List<Map<String,Object>>.

So once you have the results, you can do what you are doing. I would do something like

List results = template.queryForList(sql);

for (Map m : results){
   m.get('userid');
   m.get('username');
} 

I'll let you fill in the details, but I would not iterate over keys in this case. I like to explicit about what I am expecting.

If you have a User object, and you actually want to load User instances, you can use the queryForList that takes sql and a class type

queryForList(String sql, Class<T> elementType)

           FROM "Table_Name"

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

We had the same ORA-01775 error but in our case, the schema user was missing some 'grant select' on a couple of the public synonyms.

i had the same error while working with hibernate, i had added below dependency in my pom.xml that solved the problem

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

You can use --python option to npm like so:

npm install --python=python2.7

or set it to be used always:

npm config set python python2.7

Npm will in turn pass this option to node-gyp when needed.

(note: I'm the one who opened an issue on Github to have this included in the docs, as there were so many questions about it ;-) )

You need a private setter, if you want to support the following scenario (not only for this, but this should point out one good reason): You have a Property that is readonly in your class, i.e. only the class itself is allowed to change it, but it may change it after constructing the instance. For bindings you would then need to fire a PropertyChanged-event, preferrably this should be done in the (private) property setter. Actually, you could just fire the PropertyChanged-event from somewhere else in the class, but using the private setter for this is "good citizenship", because you do not distribute your property-change-triggers all over your class but keep it at the property, where it belongs.

YOU JUST CAN'T. There's no exact code to use for setting a forever cookie but an old trick will do, like current time + 10 years.

Just a note that any dates beyond January 2038 will doomed you for the cookies (32-bit int) will be deleted instantly. Wish for a miracle that that will be fixed in the near future. For 64-bit int, years around 2110 will be safe. As time goes by, software and hardware will change and may never adapt to older ones (the things we have now) so prepare the now for the future.

GitHub upstream.

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

The matrix for glOrtho is really simple, composed only of scaling and translation:

scalex, 0,      0,      translatex,
0,      scaley, 0,      translatey,
0,      0,      scalez, translatez,
0,      0,      0,      1

as mentioned in the OpenGL 2 docs.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

In short - JSON is a way of serializing in such a way, that it becomes JavaScript code. When executed (with eval or otherwise), this code creates and returns a JavaScript object which contains the data you serialized. This is available because JavaScript allows the following syntax:

var MyArray = [ 1, 2, 3, 4]; // MyArray is now an array with 4 elements
var MyObject = {
    'StringProperty' : 'Value',
    'IntProperty' : 12,
    'ArrayProperty' : [ 1, 2, 3],
    'ObjectProperty' : { 'SubObjectProperty': 'SomeValue' }
}; // MyObject is now an object with property values set.

You can use this for several purposes. For one, it's a comfortable way to pass data from your server backend to your JavaScript code. Thus, this is often used in AJAX.

You can also use it as a standalone serialization mechanism, which is simpler and takes up less space than XML. Many libraries exists that allow you to serialize and deserialize objects in JSON for various programming languages.

You can change the index as explained already using set_index. You don't need to manually swap rows with columns, there is a transpose (data.T) method in pandas that does it for you:

> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                    ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> newdf = df.set_index('Locality').T
> newdf

Locality    ABBOTSFORD  ABERFELDIE
2005        427000      534000
2006        448000      600000

then you can fetch the dataframe column values and transform them to a list:

> newdf['ABBOTSFORD'].values.tolist()

[427000, 448000]

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

Nearly all modern browsers now support the use of the maxlength attribute for textarea elements.(https://caniuse.com/#feat=maxlength)

To include the maxlength attribute on a multiline TextBox, you can simply modify the Attributes collection in the code behind like so:

txtTextBox.Attributes["maxlength"] = "100";

If you don't want to have to use the code behind to specify that, you can just create a custom control that derives from TextBox:

public class Textarea : TextBox
{
    public override TextBoxMode TextMode
    {
        get { return TextBoxMode.MultiLine; }
        set { }
    }

    protected override void OnPreRender(EventArgs e)
    {
        if (TextMode == TextBoxMode.MultiLine && MaxLength != 0)
        {
            Attributes["maxlength"] = MaxLength.ToString();
        }

        base.OnPreRender(e);
    }
}

Try this,to retrieve all files inside folder and sub-folder

public static void main(String[]args)
    {
        File curDir = new File(".");
        getAllFiles(curDir);
    }
    private static void getAllFiles(File curDir) {

        File[] filesList = curDir.listFiles();
        for(File f : filesList){
            if(f.isDirectory())
                getAllFiles(f);
            if(f.isFile()){
                System.out.println(f.getName());
            }
        }

    }

To retrieve files/folder only

public static void main(String[]args)
    {
        File curDir = new File(".");
        getAllFiles(curDir);
    }
    private static void getAllFiles(File curDir) {

        File[] filesList = curDir.listFiles();
        for(File f : filesList){
            if(f.isDirectory())
                System.out.println(f.getName());
            if(f.isFile()){
                System.out.println(f.getName());
            }
        }

    }

I know this is possible if the other application can attach itself to a win32 window handle. For example, we have a separate C# application that hosts a DirectX application inside one of its windows. I'm not familiar with the exact details of how this is implemented, but I think just passing the win32 Handle of your panel to the other application is enough for that application to attach its DirectX surface.

Here is my approach that you may try:

import numpy as np
import matplotlib.pyplot as plt

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = np.random.randint(10, size=(h,w))
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The resulting image:

Edit 1

Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-

1. access to individual axes of subplots
2. possibility to plot more features on selected axes/subplot

New code:

import numpy as np
import matplotlib.pyplot as plt

w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5

# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# ax enables access to manipulate each of subplots
ax = []

for i in range(columns*rows):
    img = np.random.randint(10, size=(h,w))
    # create subplot and append to ax
    ax.append( fig.add_subplot(rows, columns, i+1) )
    ax[-1].set_title("ax:"+str(i))  # set title
    plt.imshow(img, alpha=0.25)

# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)

plt.show()  # finally, render the plot

The resulting plot:

Edit 2

In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index], which is more suitable for manipulation of array of many sub-plots.

import matplotlib.pyplot as plt
import numpy as np

# settings
h, w = 10, 10        # for raster image
nrows, ncols = 5, 4  # array of sub-plots
figsize = [6, 8]     # figure size, inches

# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)

# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
    # i runs from 0 to (nrows*ncols-1)
    # axi is equivalent with ax[rowid][colid]
    img = np.random.randint(10, size=(h,w))
    axi.imshow(img, alpha=0.25)
    # get indices of row/column
    rowid = i // ncols
    colid = i % ncols
    # write row/col indices as axes' title for identification
    axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))

# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)

plt.tight_layout(True)
plt.show()

The resulting plot:

Although it is quite old question - one may find these useful (not written to be fast):

{
    $ret = '';
    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = (int)($seconds / $divs[$d]);
        $r = $seconds % $divs[$d];
        $ret .= sprintf("%d%s", $q, substr('dhms', $d, 1));
        $seconds = $r;
    }

    return $ret;

    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = (int)($seconds / $divs[$d]);
        $r = $seconds % $divs[$d];
        if ($q != 0) $can_print = true;
        if ($can_print) $ret .= sprintf("%d%s", $q, substr('dhms', $d, 1));
        $seconds = $r;
    }

    return $ret;
}

function d_h_m_s__array($seconds)
{
    $ret = array();

    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = $seconds / $divs[$d];
        $r = $seconds % $divs[$d];
        $ret[substr('dhms', $d, 1)] = $q;

        $seconds = $r;
    }

    return $ret;
}

echo d_h_m_s__string1(0*86400+21*3600+57*60+13) . "\n";
echo d_h_m_s__string2(0*86400+21*3600+57*60+13) . "\n";

$ret = d_h_m_s__array(9*86400+21*3600+57*60+13);
printf("%dd%dh%dm%ds\n", $ret['d'], $ret['h'], $ret['m'], $ret['s']);

result:

Notice that we don't pass score to the switch but true. The value we give to the switch is used as the basis to compare against.

The below example shows how we can add conditions in the case: without any if statements.

function getGrade(score) {
    let grade;
    // Write your code here
    switch(true) {
        case score >= 0 && score <= 5:
        grade = 'F';
        break;
        case score > 5 && score <= 10:
        grade = 'E';
        break;
        case score > 10 && score <= 15:
        grade = 'D';
        break;
        case score > 15 && score <= 20:
        grade = 'C';
        break;
        case score > 20 && score <= 25:
        grade = 'B';
        break;
        case score > 25 && score <= 30:
        grade = 'A';
        break;
    }

    return grade;
}

Its very simple if you use <MediaElement>:

<MediaElement  Height="113" HorizontalAlignment="Left" Margin="12,12,0,0" 
Name="mediaElement1" VerticalAlignment="Top" Width="198" Source="C:\Users\abc.gif"
LoadedBehavior="Play" Stretch="Fill" SpeedRatio="1" IsMuted="False" />

I had a similar issue, but it was related to Hibernate's bi-directional relationships. I wanted to show one side of the relationship and programmatically ignore the other, depending on what view I was dealing with. If you can't do that, you end up with nasty StackOverflowExceptions. For instance, if I had these objects

public class A{
  Long id;
  String name;
  List<B> children;
}

public class B{
  Long id;
  A parent;
}

I would want to programmatically ignore the parent field in B if I were looking at A, and ignore the children field in A if I were looking at B.

I started off using mixins to do this, but that very quickly becomes horrible; you have so many useless classes laying around that exist solely to format data. I ended up writing my own serializer to handle this in a cleaner way: https://github.com/monitorjbl/json-view.

It allows you programmatically specify what fields to ignore:

ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addSerializer(JsonView.class, new JsonViewSerializer());
mapper.registerModule(module);

List<A> list = getListOfA();
String json = mapper.writeValueAsString(JsonView.with(list)
    .onClass(B.class, match()
        .exclude("parent")));

It also lets you easily specify very simplified views through wildcard matchers:

String json = mapper.writeValueAsString(JsonView.with(list)
    .onClass(A.class, match()
        .exclude("*")
         .include("id", "name")));

In my original case, the need for simple views like this was to show the bare minimum about the parent/child, but it also became useful for our role-based security. Less privileged views of objects needed to return less information about the object.

All of this comes from the serializer, but I was using Spring MVC in my app. To get it to properly handle these cases, I wrote an integration that you can drop in to existing Spring controller classes:

@Controller
public class JsonController {
  private JsonResult json = JsonResult.instance();
  @Autowired
  private TestObjectService service;

  @RequestMapping(method = RequestMethod.GET, value = "/bean")
  @ResponseBody
  public List<TestObject> getTestObject() {
    List<TestObject> list = service.list();

    return json.use(JsonView.with(list)
        .onClass(TestObject.class, Match.match()
            .exclude("int1")
            .include("ignoredDirect")))
        .returnValue();
  }
}

Both are available on Maven Central. I hope it helps someone else out there, this is a particularly ugly problem with Jackson that didn't have a good solution for my case.

If you don't want to use jQuery and want to support older browsers:

function addClass(elem, clazz) {
    if (!elemHasClass(elem, clazz)) {
        elem.className += " " + clazz;
    }
}

function elemHasClass(elem, clazz) {
    return new RegExp("( |^)" + clazz + "( |$)").test(elem.className);
}

The orginal polarToCartesian function by wdebeaum is correct:

var angleInRadians = angleInDegrees * Math.PI / 180.0;

Reversing of start and end points by using:

var start = polarToCartesian(x, y, radius, endAngle);
var end = polarToCartesian(x, y, radius, startAngle);

Is confusing (to me) because this will reverse the sweep-flag. Using:

var start = polarToCartesian(x, y, radius, startAngle);
var end = polarToCartesian(x, y, radius, endAngle);

with the sweep-flag = "0" draws "normal" counter-clock-wise arcs, which I think is more straight forward. See https://developer.mozilla.org/en-US/docs/Web/SVG/Tutorial/Paths

Intent chooser = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getDownloadCacheDirectory().getPath().toString());
chooser.addCategory(Intent.CATEGORY_OPENABLE);
chooser.setDataAndType(uri, "*/*");
// startActivity(chooser);
try {
startActivityForResult(chooser, SELECT_FILE);
}
catch (android.content.ActivityNotFoundException ex)
{
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}

In code above, if setDataAndType is "*/*" a builtin file browser is opened to pick any file, if I set "text/plain" Dropbox is opened. I have Dropbox, Google Drive installed. If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).

You can use

SELECT AUTO_INCREMENT
FROM information_schema.tables
WHERE table_name = 'table_name'
AND table_schema = DATABASE( ) ;

or if you do not wish to use information_schema you can use this

SHOW TABLE STATUS LIKE 'table_name'

Since you know how many types of layout you would have - it's possible to use those methods.

getViewTypeCount() - this methods returns information how many types of rows do you have in your list

getItemViewType(int position) - returns information which layout type you should use based on position

Then you inflate layout only if it's null and determine type using getItemViewType.

Look at this tutorial for further information.

To achieve some optimizations in structure that you've described in comment I would suggest:

• Storing views in object called ViewHolder. It would increase speed because you won't have to call findViewById() every time in getView method. See List14 in API demos.
• Create one generic layout that will conform all combinations of properties and hide some elements if current position doesn't have it.

I hope that will help you. If you could provide some XML stub with your data structure and information how exactly you want to map it into row, I would be able to give you more precise advise. By pixel.

Is this what you are after? Just index the element and assign a new value.

you can use cURL library for posting data: http://www.php.net/curl

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, "http://websiteURL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent."&password=".$password."&etc=etc");
$content=curl_exec($ch);

where postfield contains XML you need to send - you will need to name the postfield the API service (Clickatell I guess) expects

This did the job (in the year 2012):

#include <stdio.h>
const unsigned long long size = 8ULL*1024ULL*1024ULL;
unsigned long long a[size];

int main()
{
    FILE* pFile;
    pFile = fopen("file.binary", "wb");
    for (unsigned long long j = 0; j < 1024; ++j){
        //Some calculations to fill a[]
        fwrite(a, 1, size*sizeof(unsigned long long), pFile);
    }
    fclose(pFile);
    return 0;
}

I just timed 8GB in 36sec, which is about 220MB/s and I think that maxes out my SSD. Also worth to note, the code in the question used one core 100%, whereas this code only uses 2-5%.

Thanks a lot to everyone.

Update: 5 years have passed it's 2017 now. Compilers, hardware, libraries and my requirements have changed. That's why I made some changes to the code and did some new measurements.

First up the code:

#include <fstream>
#include <chrono>
#include <vector>
#include <cstdint>
#include <numeric>
#include <random>
#include <algorithm>
#include <iostream>
#include <cassert>

std::vector<uint64_t> GenerateData(std::size_t bytes)
{
    assert(bytes % sizeof(uint64_t) == 0);
    std::vector<uint64_t> data(bytes / sizeof(uint64_t));
    std::iota(data.begin(), data.end(), 0);
    std::shuffle(data.begin(), data.end(), std::mt19937{ std::random_device{}() });
    return data;
}

long long option_1(std::size_t bytes)
{
    std::vector<uint64_t> data = GenerateData(bytes);

    auto startTime = std::chrono::high_resolution_clock::now();
    auto myfile = std::fstream("file.binary", std::ios::out | std::ios::binary);
    myfile.write((char*)&data[0], bytes);
    myfile.close();
    auto endTime = std::chrono::high_resolution_clock::now();

    return std::chrono::duration_cast<std::chrono::milliseconds>(endTime - startTime).count();
}

long long option_2(std::size_t bytes)
{
    std::vector<uint64_t> data = GenerateData(bytes);

    auto startTime = std::chrono::high_resolution_clock::now();
    FILE* file = fopen("file.binary", "wb");
    fwrite(&data[0], 1, bytes, file);
    fclose(file);
    auto endTime = std::chrono::high_resolution_clock::now();

    return std::chrono::duration_cast<std::chrono::milliseconds>(endTime - startTime).count();
}

long long option_3(std::size_t bytes)
{
    std::vector<uint64_t> data = GenerateData(bytes);

    std::ios_base::sync_with_stdio(false);
    auto startTime = std::chrono::high_resolution_clock::now();
    auto myfile = std::fstream("file.binary", std::ios::out | std::ios::binary);
    myfile.write((char*)&data[0], bytes);
    myfile.close();
    auto endTime = std::chrono::high_resolution_clock::now();

    return std::chrono::duration_cast<std::chrono::milliseconds>(endTime - startTime).count();
}

int main()
{
    const std::size_t kB = 1024;
    const std::size_t MB = 1024 * kB;
    const std::size_t GB = 1024 * MB;

    for (std::size_t size = 1 * MB; size <= 4 * GB; size *= 2) std::cout << "option1, " << size / MB << "MB: " << option_1(size) << "ms" << std::endl;
    for (std::size_t size = 1 * MB; size <= 4 * GB; size *= 2) std::cout << "option2, " << size / MB << "MB: " << option_2(size) << "ms" << std::endl;
    for (std::size_t size = 1 * MB; size <= 4 * GB; size *= 2) std::cout << "option3, " << size / MB << "MB: " << option_3(size) << "ms" << std::endl;

    return 0;
}

This code compiles with Visual Studio 2017 and g++ 7.2.0 (a new requirements). I ran the code with two setups:

• Laptop, Core i7, SSD, Ubuntu 16.04, g++ Version 7.2.0 with -std=c++11 -march=native -O3
• Desktop, Core i7, SSD, Windows 10, Visual Studio 2017 Version 15.3.1 with /Ox /Ob2 /Oi /Ot /GT /GL /Gy

Which gave the following measurements (after ditching the values for 1MB, because they were obvious outliers): Both times option1 and option3 max out my SSD. I didn't expect this to see, because option2 used to be the fastest code on my old machine back then.

TL;DR: My measurements indicate to use std::fstream over FILE.

Work 100% sure try this code for the get all hashmap key and value

static HashMap<String, String> map = new HashMap<>();

map.put("one"  " a " );
map.put("two"  " b " );
map.put("three"  " c " );
map.put("four"  " d " );

just call this method whenever you want to show the HashMap value

 private void ShowHashMapValue() {

        /**
         * get the Set Of keys from HashMap
         */
        Set setOfKeys = map.keySet();

/**
 * get the Iterator instance from Set
 */
        Iterator iterator = setOfKeys.iterator();

/**
 * Loop the iterator until we reach the last element of the HashMap
 */
        while (iterator.hasNext()) {
/**
 * next() method returns the next key from Iterator instance.
 * return type of next() method is Object so we need to do DownCasting to String
 */
            String key = (String) iterator.next();

/**
 * once we know the 'key', we can get the value from the HashMap
 * by calling get() method
 */
            String value = map.get(key);

            System.out.println("Key: " + key + ", Value: " + value);
        }
    } 

For me my service that I created had to be uninstalled in Control Panel > Programs and Features

I have hit this problem in the past - from the look of it if you don't actually need the clipboard at the point that you exit, so you can use the same simple solution I had. Just clear the clipboard. :)

ActiveCell.Copy

I noticed this post was old but it appears top on google and this kind of solution was never offered so I decided to post it anyway.

You can just disable cursor-events and enable them again later via css. It is supported on all major browsers and may prove useful in some situations.

$("#button_id").click(function() {

   $("#button_id").css("pointer-events", "none");
   //do something
   $("#button_id").css("pointer-events", "auto");
}

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

Use This for MAC users

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

There is a RawFormat property of Image parameter which returns the file format of the image. You might try the following:

// extension method
public static byte[] imageToByteArray(this System.Drawing.Image image)
{
    using(var ms = new MemoryStream())
    {
        image.Save(ms, image.RawFormat);
        return ms.ToArray();
    }
}

You want to use regexp_substr() for this. This should work for your example:

select regexp_substr(val, '[^/]+/[^/]+', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

Here, by the way, is the SQL Fiddle.

Oops. I missed the part of the question where it says the last delimiter. For that, we can use regex_replace() for the first part:

select regexp_replace(val, '/[^/]+$', '', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

And here is this corresponding SQL Fiddle.

I'm using json lib from http://json-lib.sourceforge.net/
json-lib-2.1-jdk15.jar

import net.sf.json.JSONObject;
...

public void send()
{
    //put attributes
    Map m = New HashMap();
    m.put("send_to","[email protected]");
    m.put("email_subject","this is a test email");
    m.put("email_content","test email content");

    //generate JSON Object
    JSONObject json = JSONObject.fromObject(content);
    String message = json.toString();
    ...
}

public void receive(String jsonMessage)
{
    //parse attributes
    JSONObject json = JSONObject.fromObject(jsonMessage);
    String to = (String) json.get("send_to");
    String title = (String) json.get("email_subject");
    String content = (String) json.get("email_content");
    ...
}

Situation for ES 6

The upcoming ECMAScript language specification, edition 6, includes Unicode-aware regular expressions. Support must be enabled with the u modifier on the regex. See Unicode-aware regular expressions in ES6.

Until ES 6 is finished and widely adopted among browser vendors you're still on your own, though. Update: There is now a transpiler named regexpu that translates ES6 Unicode regular expressions into equivalent ES5. It can be used as part of your build process. Try it out online.

Situation for ES 5 and below

Even though JavaScript operates on Unicode strings, it does not implement Unicode-aware character classes and has no concept of POSIX character classes or Unicode blocks/sub-ranges.

• Issues with Unicode in JavaScript regular expressions

• Check your expectations here: Javascript RegExp Unicode Character Class tester (Edit: the original page is down, the Internet Archive still has a copy.)

• Flagrant Badassery has an article on JavaScript, Regex, and Unicode that sheds some light on the matter.

• Also read Regex and Unicode here on SO. Probably you have to build your own "punctuation character class".

• Check out the Regular Expression: Match Unicode Block Range builder, which lets you build a JavaScript regular expression that matches characters that fall in any number of specified Unicode blocks.

  I just did it for the "General Punctuation" and "Supplemental Punctuation" sub-ranges, and the result is as simple and straight-forward as I would have expected it:

   [\u2000-\u206F\u2E00-\u2E7F]
  

• There also is XRegExp, a project that brings Unicode support to JavaScript by offering an alternative regex engine with extended capabilities.

• And of course, required reading: mathiasbynens.be - JavaScript has a Unicode problem:

Set log_statement to all:

Error Reporting and Logging - log_statement

Based on previous functions found in this post. Added recursive mode and indentation.

function dump(v, s) {
  s = s || 1;
  var t = '';
  switch (typeof v) {
    case "object":
      t += "\n";
      for (var i in v) {
        t += Array(s).join(" ")+i+": ";
        t += dump(v[i], s+3);
      }
      break;
    default: //number, string, boolean, null, undefined 
      t += v+" ("+typeof v+")\n";
      break;
  }
  return t;
}

Example

var a = {
  b: 1,
  c: {
    d:1,
    e:2,
    d:3,
    c: {
      d:1,
      e:2,
      d:3
    }
  }
};

var d = dump(a);
console.log(d);
document.getElementById("#dump").innerHTML = "<pre>" + d + "</pre>";

Result

b: 1 (number)
c: 
   d: 3 (number)
   e: 2 (number)
   c: 
      d: 3 (number)
      e: 2 (number)

The X-Frame-Options header is a security feature enforced at the browser level.

If you have control over your user base (IT dept for corp app), you could try something like a greasemonkey script (if you can a) deploy greasemonkey across everyone and b) deploy your script in a shared way)...

Alternatively, you can proxy their result. Create an endpoint on your server, and have that endpoint open a connection to the target endpoint, and simply funnel traffic backwards.

Often your value occurs at multiple indices:

>>> myseries = pd.Series([0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 1, 1])
>>> myseries.index[myseries == 1]
Int64Index([3, 4, 5, 6, 10, 11], dtype='int64')

I'm a bit late to the party, however there's an important note:

Your scripts might be in the right order but watch out for any asyncs in your script tag (like this)

<script type="text/javascript" src="js/bootstrap.js" async></script>

This might be causing the issue. Especially if you have this async set only for Production environments this can get really frustrating to reason about.

Scenario 1: You had Eclipse showing server and now after removing the particular version you want to configure at Eclipse a new local server instance. But you can not move further.

This happens due to reason Eclipse still looks for configured version of Tomcat directory, which directory is no longer there.

There is no need till LUNA to make fresh installation!

All we need is to REPLACE the new server run time environment into eclipse after removing old one, which is non-existent. Eclipse will

Try this;

Add-Content -path $logpath @"
$((get-date).tostring()) Error $keyPath $value
key $key expected: $policyValue
local value is:  $localValue

The link you gave seems to be attempting something different to the test you are trying to avoid repeating.

if (a == null || a=='')

tests if the string is an empty string or null. The article you linked to tests if the string consists entirely of whitespace (or is empty).

The test you described can be replaced by:

if (!a)

Because in javascript, an empty string, and null, both evaluate to false in a boolean context.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

You can update your provisioning certificates in XCode at:

Organizer -> Devices -> LIBRARY -> Provisioning Profiles

There is a refresh button :) So if you have created the certificate manually in iTunes connect, then you need to press this button or download the certificate manually.

alert("xxxxxxxxxxx_456".substr(-3))

caveat: according to mdc, not IE compatible

You shouldn't include other source files (*.c) in .c files. I think you want to have a header (.h) file with the DECLARATION of test function, and have it's DEFINITION in a separate .c file.

The error is caused by multiple definitions of the test function (one in test.c and other in main.c)

Not really an answer to your question but validating url's is really a serious p.i.t.a You're probably just better off validating the domainname and leave query part of the url be. That is my experience. You could also resort to pinging the url and seeing if it results in a valid response but that might be too much for such a simple task.

Regular expressions to detect url's are abundant, google it :)

Complement with an additional example, you can access all job parameters in JavaConfig class:

@Bean
@StepScope
public ItemStreamReader<GenericMessage> reader(@Value("#{jobParameters}") Map<String,Object> jobParameters){
          ....
}

I know this is an old question but still, I came across a similar problem and i realized that my "not working" css code in my bootstrapOverload.css file was written after the media queries. when I moved it above media queries it started working.

Just in case someone else is facing the same problem

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

How can I get the index of the object tha match a condition (without iterate along the array)?

You cannot, something has to iterate through the array (at least once).

If the condition changes a lot, then you'll have to loop through and look at the objects therein to see if they match the condition. However, on a system with ES5 features (or if you install a shim), that iteration can be done fairly concisely:

var index;
yourArray.some(function(entry, i) {
    if (entry.prop2 == "yutu") {
        index = i;
        return true;
    }
});

That uses the new(ish) Array#some function, which loops through the entries in the array until the function you give it returns true. The function I've given it saves the index of the matching entry, then returns true to stop the iteration.

Or of course, just use a for loop. Your various iteration options are covered in this other answer.

But if you're always going to be using the same property for this lookup, and if the property values are unique, you can loop just once and create an object to map them:

var prop2map = {};
yourArray.forEach(function(entry) {
    prop2map[entry.prop2] = entry;
});

(Or, again, you could use a for loop or any of your other options.)

Then if you need to find the entry with prop2 = "yutu", you can do this:

var entry = prop2map["yutu"];

I call this "cross-indexing" the array. Naturally, if you remove or add entries (or change their prop2 values), you need to update your mapping object as well.

This should further clarify the points:

a = int(raw_input('Enter the index'))
str1 = 'Example'
leng = len(str1)
if (a < (len-1)) and (a > (-len)):
    print str1[a]
else:
    print('Index overflow')

Input 3 Output m

Input -3 Output p

PsFile does work on remote machines. If my login account already has access to the remote share, I can just enter:

psfile \\remote-share

(replace "remote-share" with the name of your file server) and it will list every opened document on that share, along with who has it open, and the file ID if I want to force the file closed. For me, this is a really long list, but it can be narrowed down by entering part of a path:

psfile \\remote-share I:\\Human_Resources

This is kind of tricky, since in my case this remote share is mounted as Z: on my local machine, but psfile identifies paths as they are defined on the remote file server, which in my case is I: (yours will be different). I just had to comb through the results of my first psfile run to see some of the paths it returned and then run it again with a partial path to narrow down the results.

Optionally, PsFile will let you specify credentials for the remote share if you need to supply them for access.

Lastly, a little known tip: if someone clicks on a file in Windows Explorer and cuts or copies the file with the intent to paste it somewhere else, that act also places a lock on the file.

INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).

You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).

To Store "Country + area + number separately". You can try using a VARCHAR(20), this allows you the ability to store international phone numbers properly, should that need arise.

Regarding seek() there's not too much to worry about.

First of all, it is useful when operating over an open file.

It's important to note that its syntax is as follows:

fp.seek(offset, from_what)

where fp is the file pointer you're working with; offset means how many positions you will move; from_what defines your point of reference:

• 0: means your reference point is the beginning of the file
• 1: means your reference point is the current file position
• 2: means your reference point is the end of the file

if omitted, from_what defaults to 0.

Never forget that when managing files, there'll always be a position inside that file where you are currently working on. When just open, that position is the beginning of the file, but as you work with it, you may advance.
seek will be useful to you when you need to walk along that open file, just as a path you are traveling into.

You can do this using jQuery:

This method gets a list of its children then counts the length of that list, as simple as that.

$("ul").find("*").length;

The find() method traverses DOM downwards along descendants, all the way down to the last descendant.

Note: children() method traverses a single level down the DOM tree.

I just used Midhat's answer but appended CopyToDataTable() on the end.

The code below is an extension to the answer that I used to quickly enable some paging.

int pageNum = 1;
int pageSize = 25;

DataTable dtPage = dt.Rows.Cast<System.Data.DataRow>().Skip((pageNum - 1) * pageSize).Take(pageSize).CopyToDataTable();

In Java an array has a fixed size (after initialisation), meaning that you can't add or remove items from an array.

int[] i = new int[10];

The above snippet mean that the array of integers has a length of 10. It's not possible add an eleventh integer, without re-assign the reference to a new array, like the following:

int[] i = new int[11];

In Java the package java.util contains all kinds of data structures that can handle adding and removing items from array-like collections. The classic data structure Stack has methods for push and pop.

Download HAXM from SDK Manager

Open your SDK Manager from Android Studio, click the icon shown in the screen shot.

Click on "Launch Standalone SDK Manager" on the "Default Settings" Dialog.

Check node "Extras > Intel x86 Emulator Accelerator (HAXM installer)" and proceed with HAXM download.

Installing or Modifying HAXM

You can now access with installation (or modifying existing installtino) of HAXM by accessing the download location. Enter this path in "run"

%localappdata%\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager

and double click the file "intelhaxm-android.exe"

You can increase the size of memory allocated to HAXM while modifying existing HAXM install. I have a machine with 32 GB of RAM and would like to launch multiple AVDs at same time (for automated testing etc.) so I have allocated 8 GB to HAXM.

Caveat

If you are running one AVD of one 1 GB and allocated 2 GB to HAXM, you cannot run another AVD with RAM more than 1 GB. Please make sure that Android Device Monitor is not running when you are modifying or installing HAXM (just to avoid any suprises).

These steps are tested on Windows platform, but generally could be applied to other platforms too with slight modification.

A 'router' could be doing anything - particularly NAT, which might involve any amount of bug-ridden messing with traffic...

One reason a device will send a RST is in response to receiving a packet for a closed socket.

It's hard to give a firm but general answer, because every possible perversion has been visited on TCP since its inception, and all sorts of people might be inserting RSTs in an attempt to block traffic. (Some 'national firewalls' work like this, for example.)

Using combination pushd, git pull and popd, we can achieve this functionality:

pushd <path-to-git-repo> && git pull && popd

For example:

pushd "E:\Fake Directory\gitrepo" && git pull && popd

Filter: - A filter as the name suggests is a Java class executed by the servlet container for each incoming HTTP request and for each http response. This way, is possible to manage HTTP incoming requests before them reach the resource, such as a JSP page, a servlet or a simple static page; in the same way is possible to manage HTTP outbound response after resource execution.

Interceptor: - Spring Interceptors are similar to Servlet Filters but they acts in Spring Context so are many powerful to manage HTTP Request and Response but they can implement more sophisticated behavior because can access to all Spring context.

This solution demonstrates how to transform data with Spark native functions which are better than UDFs. It also demonstrates how dropDuplicates which is more suitable than distinct for certain queries.

Suppose you have this DataFrame:

+-------+-------------+
|country|    continent|
+-------+-------------+
|  china|         asia|
| brazil|south america|
| france|       europe|
|  china|         asia|
+-------+-------------+

Here's how to take all the distinct countries and run a transformation:

df
  .select("country")
  .distinct
  .withColumn("country", concat(col("country"), lit(" is fun!")))
  .show()

+--------------+
|       country|
+--------------+
|brazil is fun!|
|france is fun!|
| china is fun!|
+--------------+

You can use dropDuplicates instead of distinct if you don't want to lose the continent information:

df
  .dropDuplicates("country")
  .withColumn("description", concat(col("country"), lit(" is a country in "), col("continent")))
  .show(false)

+-------+-------------+------------------------------------+
|country|continent    |description                         |
+-------+-------------+------------------------------------+
|brazil |south america|brazil is a country in south america|
|france |europe       |france is a country in europe       |

Ultimately, you'll want to wrap your transformation logic in custom transformations that can be chained with the Dataset#transform method.

You can add this to onCreate and it will hide the keyboard every time the Activity starts.

You can also programmatically change the focus to another item.

 this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

When you want to read a file with a different configuration than the default one, feel free to use either mpu.aws.s3_read(s3path) directly or the copy-pasted code:

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

EPL2011_12$Date <- as.Date(EPL2011_12$Date, "%d-%m-%y")

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

For Swift 2.0:

emailBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left  

This can help if any one needed.

This answer assumes that you have python3.6 installed. For python3.7, replace 3.6 with 3.7. For python3.8, replace 3.6 with 3.8, but it may also first require the python3.8-distutils package.

Installation with sudo

With regard to installing pip, using curl (instead of wget) avoids writing the file to disk.

curl https://bootstrap.pypa.io/get-pip.py | sudo -H python3.6

The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter:

The directory '/home/someuser/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

The directory '/home/someuser/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Installation without sudo

curl https://bootstrap.pypa.io/get-pip.py | python3.6 - --user

This may sometimes give a warning such as:

WARNING: The script wheel is installed in '/home/ubuntu/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

Verification

After this, pip, pip3, and pip3.6 can all be expected to point to the same target:

$ (pip -V && pip3 -V && pip3.6 -V) | uniq
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Of course you can alternatively use python3.6 -m pip as well.

$ python3.6 -m pip -V
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To convert your JSON string to hashmap you can make use of this :

HashMap<String, Object> hashMap = new HashMap<>(Utility.jsonToMap(response)) ;

Use this class :) (handles even lists , nested lists and json)

public class Utility {

    public static Map<String, Object> jsonToMap(Object json) throws JSONException {

        if(json instanceof JSONObject)
            return _jsonToMap_((JSONObject)json) ;

        else if (json instanceof String)
        {
            JSONObject jsonObject = new JSONObject((String)json) ;
            return _jsonToMap_(jsonObject) ;
        }
        return null ;
    }


   private static Map<String, Object> _jsonToMap_(JSONObject json) throws JSONException {
        Map<String, Object> retMap = new HashMap<String, Object>();

        if(json != JSONObject.NULL) {
            retMap = toMap(json);
        }
        return retMap;
    }


    private static Map<String, Object> toMap(JSONObject object) throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();

        Iterator<String> keysItr = object.keys();
        while(keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = object.get(key);

            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            map.put(key, value);
        }
        return map;
    }


    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for(int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }
        return list;
    }
}

An optional parameter is just tagged with an attribute. This attribute tells the compiler to insert the default value for that parameter at the call-site.

The call obj2.TestMethod(); is replaced by obj2.TestMethod(false); when the C# code gets compiled to IL, and not at JIT-time.

So in a way it's always the caller providing the default value with optional parameters. This also has consequences on binary versioning: If you change the default value but don't recompile the calling code it will continue to use the old default value.

On the other hand, this disconnect means you can't always use the concrete class and the interface interchangeably.

You already can't do that if the interface method was implemented explicitly.

Here's a test with multiple sample sizes in milliseconds.

Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.

Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.

If you are comparing schemas on the same database then try:

select * from dba_objects 
   where schema_name = 'ASCHEMA' 
     and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects 
where schema_name = 'BSCHEMA' 
  and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )

and switch around the orders of ASCHEMA and BSCHEMA.

If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

Based on the given answers and information in the question, this is the code you should use:

public static boolean doesURLExist(URL url) throws IOException
{
    // We want to check the current URL
    HttpURLConnection.setFollowRedirects(false);

    HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

    // We don't need to get data
    httpURLConnection.setRequestMethod("HEAD");

    // Some websites don't like programmatic access so pretend to be a browser
    httpURLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
    int responseCode = httpURLConnection.getResponseCode();

    // We only accept response code 200
    return responseCode == HttpURLConnection.HTTP_OK;
}

Of course tested and working.

The sklearn.metrics.accuracy_score(y_true, y_pred) method defines y_pred as:

y_pred : 1d array-like, or label indicator array / sparse matrix. Predicted labels, as returned by a classifier.

Which means y_pred has to be an array of 1's or 0's (predicated labels). They should not be probabilities.

The predicated labels (1's and 0's) and/or predicted probabilites can be generated using the LinearRegression() model's methods predict() and predict_proba() respectively.

1. Generate predicted labels:

LR = linear_model.LinearRegression()
y_preds=LR.predict(X_test)
print(y_preds)

output:

[1 1 0 1]

y_preds can now be used for the accuracy_score() method: accuracy_score(y_true, y_pred)

2. Generate probabilities for labels:

Some metrics such as 'precision_recall_curve(y_true, probas_pred)' require probabilities, which can be generated as follows:

LR = linear_model.LinearRegression()
y_preds=LR.predict_proba(X_test)
print(y_preds)

output:

[0.87812372 0.77490434 0.30319547 0.84999743]

The best way is:

  $ docker cp CONTAINER:FILEPATH LOCALFILEPATH
  $ vi LOCALFILEPATH
  $ docker cp LOCALFILEPATH CONTAINER:FILEPATH

Limitations with $ docker exec: it can only attach to a running container.

Limitations with $ docker run: it will create a new container.

Step 1: Install XML Tools plugin
Step 2: Format ....completed

Surya, your way won't work, because of two reasons:

1. you can't close driver during evaluation of test as it will loose focus, before switching to active element, and you'll get NoSuchWindowException.
2. if test are run on ChromeDriver you`ll get not a window, but tab on click in your application. As SeleniumDriver can't act with tabs, only switchs between windows, it hangs on click where new tab is being opening, and crashes on timeout.

This will squash second commit into the first one:

A-B-C-... -> AB-C-...

git filter-branch --commit-filter '
    if [ "$GIT_COMMIT" = <sha1ofA> ];
    then
        skip_commit "$@";
    else
        git commit-tree "$@";
    fi
' HEAD

Commit message for AB will be taken from B (although I'd prefer from A).

Has the same effect as Uwe Kleine-König's answer, but works for non-initial A as well.

Read this (supplementary) answer (that is sometimes the answer) to understand where this is going and why some people in this thread complain that "it is still not working"

I wrote exactly same code as one of the answers here. But I still had an issue. I placed break point on

var mi = o.GetType().GetMethod(methodName, BindingFlags.NonPublic | BindingFlags.Instance );

It executed but mi == null

And it continued behavior like this until I did "re-build" on all projects involved. I was unit testing one assembly while the reflection method was sitting in third assembly. It was totally confusing but I used Immediate Window to discover methods and I found that a private method I tried to unit test had old name (I renamed it). This told me that old assembly or PDB is still out there even if unit test project builds - for some reason project it tests didn't built. "rebuild" worked

tl;dr

Use java.time.Instant class to parse text in standard ISO 8601 format, representing a moment in UTC.

Instant.parse( "2010-10-02T12:23:23Z" )

ISO 8601

That format is defined by the ISO 8601 standard for date-time string formats.

Both:

• java.time framework built into Java 8 and later (Tutorial)
• Joda-Time library

…use ISO 8601 formats by default for parsing and generating strings.

You should generally avoid using the old java.util.Date/.Calendar & java.text.SimpleDateFormat classes as they are notoriously troublesome, confusing, and flawed. If required for interoperating, you can convert to and fro.

java.time

Built into Java 8 and later is the new java.time framework. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

Instant instant = Instant.parse( "2010-10-02T12:23:23Z" );  // `Instant` is always in UTC.

Convert to the old class.

java.util.Date date = java.util.Date.from( instant );  // Pass an `Instant` to the `from` method.

Time Zone

If needed, you can assign a time zone.

ZoneId zoneId = ZoneId.of( "America/Montreal" ); // Define a time zone rather than rely implicitly on JVM’s current default time zone.
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );  // Assign a time zone adjustment from UTC.

Convert.

java.util.Date date = java.util.Date.from( zdt.toInstant() );  // Extract an `Instant` from the `ZonedDateTime` to pass to the `from` method.

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode. The team advises migration to the java.time classes.

Here is some example code in Joda-Time 2.8.

org.joda.time.DateTime dateTime_Utc = new DateTime( "2010-10-02T12:23:23Z" , DateTimeZone.UTC );  // Specifying a time zone to apply, rather than implicitly assigning the JVM’s current default.

Convert to old class. Note that the assigned time zone is lost in conversion, as j.u.Date cannot be assigned a time zone.

java.util.Date date = dateTime_Utc.toDate(); // The `toDate` method converts to old class.

Time Zone

If needed, you can assign a time zone.

DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime dateTime_Montreal = dateTime_Utc.withZone ( zone );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

In angular 1.4 +, in addition to adding the dependency

angular.module('myApp', ['ngRoute'])

,we also need to reference the separate angular-route.js file

<script src="angular.js">
<script src="angular-route.js">

see https://docs.angularjs.org/api/ngRoute

The explanation that none of the other answers supplies is that the original arguments are still available, but not in the original position in the arguments object.

The arguments object contains one element for each actual parameter provided to the function. When you call a you supply three arguments: the numbers 1, 2, and, 3. So, arguments contains [1, 2, 3].

function a(args){
    console.log(arguments) // [1, 2, 3]
    b(arguments);
}

When you call b, however, you pass exactly one argument: a's arguments object. So arguments contains [[1, 2, 3]] (i.e. one element, which is a's arguments object, which has properties containing the original arguments to a).

function b(args){
    // arguments are lost?
    console.log(arguments) // [[1, 2, 3]]
}

a(1,2,3);

As @Nick demonstrated, you can use apply to provide a set arguments object in the call.

The following achieves the same result:

function a(args){
    b(arguments[0], arguments[1], arguments[2]); // three arguments
}

But apply is the correct solution in the general case.

Here's my overview about built-in zi/unzip (compress/decompress) capabilities in windows - How can I compress (/ zip ) and uncompress (/ unzip ) files and folders with batch file without using any external tools?

To unzip file you can use this script :

zipjs.bat unzip -source C:\myDir\myZip.zip -destination C:\MyDir -keep yes -force no

What about inv?

e.g.: my_inverse_array = inv(my_array)

You must first check whether response[0] is undefined, and only if it's not, check for the rest. That means that in your case, response[0] is undefined.

Keep it simple :

/**
 * This function will take an URL as input and return the file name.
 * <p>Examples :</p>
 * <ul>
 * <li>http://example.com/a/b/c/test.txt -> test.txt</li>
 * <li>http://example.com/ -> an empty string </li>
 * <li>http://example.com/test.txt?param=value -> test.txt</li>
 * <li>http://example.com/test.txt#anchor -> test.txt</li>
 * </ul>
 * 
 * @param url The input URL
 * @return The URL file name
 */
public static String getFileNameFromUrl(URL url) {

    String urlString = url.getFile();

    return urlString.substring(urlString.lastIndexOf('/') + 1).split("\\?")[0].split("#")[0];
}

Always mention max-width and min-width in some unit like px or rem. This figured it out for me. If I write it without the unit and only the number value, browser can't read the media queries. example: this is wrong @media only screen and (max-width:950) and this is right @media only screen and (max-width:950px)

Tested and Working over Chrome, Firefox, Opera and Edge by 2016/10. Should work on any browser and should always look as expected.

v-flex does not have a display flex! Inspect v-flex in your browser and you will find out it is just a simple block div.

So, you should override it with display: flex in your HTML or CSS to make it work with justify-content.

<ul>
    @foreach (int aPromotion in @Enum.GetValues(typeof(UserPromotion)))
    {
        var currentPromotion = (int)Model.JobSeeker.Promotion;
        if ((currentPromotion & aPromotion) == aPromotion)
        {
        <li>@Html.DisplayFor(e => currentPromotion)</li>
        }
    }
</ul>

You can use the collate clause in a query (I can't find my example right now, so my syntax is probably wrong - I hope it points you in the right direction)

select sone_field collate SQL_Latin1_General_CP850_CI_AI
  from table_1
    inner join table_2
      on (table_1.field collate SQL_Latin1_General_CP850_CI_AI = table_2.field)
  where whatever

Note that find . -type f | xargs grep whatever sorts of solutions will run into "Argument list to long" errors when there are too many files matched by find.

The best bet is grep -r but if that isn't available, use find . -type f -exec grep -H whatever {} \; instead.

Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.

Try using this command to allow a port

sudo ufw allow 1701

To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:

nc -l 1701

Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.

It looks like the files npm uses to edit its config files are not created on a clean install, as npm has a default option for each one. This is why you can still get options with npm config get <option>: having those files only overrides the defaults, it doesn't create the options from scratch.

I had never touched my npm config stuff before today, even though I had had it for months now. None of the files were there yet, such as ~/.npmrc (on a Windows 8.1 machine with Git Bash), yet I could run npm config get <something> and, if it was a correct npm option, it returned a value. When I ran npm config set <option> <value>, the file ~/.npmrc seemed to be created automatically, with the option & its value as the only non-commented-out line.

As for deleting options, it looks like this just sets the value back to the default value, or does nothing if that option was never set or was unset & never reset. Additionally, if that option is the only explicitly set option, it looks like ~/.npmrc is deleted, too, and recreated if you set anything else later.

In your case (assuming it is still the same over a year later), it looks like you never set the proxy option in npm. Therefore, as npm's config help page says, it is set to whatever your http_proxy (case-insensitive) environment variable is. This means there is nothing to delete, unless you want to "delete" your HTTP proxy, although you could set the option or environment variable to something else and hope neither breaks your set-up somehow.

This is an old post, but thanks to this post I have found this:

\! echo 'some text';

Tested with MySQL 8 and working correctly. Cool right? :)

Try this code for to trim a String

Public Function AllTrim(ByVal GeVar As String) As String
    Dim i As Integer
    Dim e As Integer
    Dim NewStr As String = ""
    e = Len(GeVar)
    For i = 1 To e
        If Mid(GeVar, i, 1) <> " " Then
            NewStr = NewStr + Mid(GeVar, i, 1)
        End If
    Next i
    AllTrim = NewStr
    ' MsgBox("alltrim = " & NewStr)
End Function

Try this out...

$('select option:first-child').attr("selected", "selected");

Another option would be this, but it will only work for one drop down list at a time as coded below:

var myDDL = $('myID');
myDDL[0].selectedIndex = 0;

Take a look at this post on how to set based on value, its interesting but won't help you for this specific issue:

Design patterns are just tools--kind of like library functions. If you know that they are there and their approximate function, you can go dig them out of a book when needed.

There is nothing magic about design patterns, and any good programmer figured 90% of them out for themselves before any books came out. For the most part I consider the books to be most useful at simply defining names for the various patterns so we can discuss them more easily.

To return only one row use LIMIT 1:

SELECT *
FROM tbl_foo
WHERE name = 'sarmen'
LIMIT 1

It doesn't make sense to say 'first row' or 'last row' unless you have an ORDER BY clause. Assuming you add an ORDER BY clause then you can use LIMIT in the following ways:

• To get the first row use LIMIT 1.
• To get the 2nd row you can use limit with an offset: LIMIT 1, 1.
• To get the last row invert the order (change ASC to DESC or vice versa) then use LIMIT 1.

First you have to clone the repository to you local machine

git clone github_url local_directory

Then you can create local folders and files inside your local_directory, and add them to the repository using:

git add file_path

You can also add everything using:

git add .

Note that Git does not track empty folders. A workaround is to create a file inside the empty folder you want to track. I usually name that file empty, but it can be whatever name you choose.

Finally, you commit and push back to GitHub:

git commit
git push

For more information on Git, check out the Pro Git book.

The simple answer is not in Javascript the simplest way to get the placeholder is through the place holder attribute

<input type="text" name="text_box_1" placeholder="My Default Value" />

I was facing this issue only while importing my own created components/services For those of you like me, for whom the accepted solution did not work, can try this:

Add

"baseUrl": "src"

in your tsconfig.json. The reason is that visual code IDE is unable to resolve the base url so is unable to resolve path to imported components and gives error/warning.

Whereas angular compiler takes src as baseurl by default so it is able to compile.

NOTE:

You need to restart VS Code IDE to make this change come into effect.

EDIT:

As mentioned in one of the comments, in some cases changing workspace version might also work. More details here: https://github.com/Microsoft/vscode/issues/34681#issuecomment-331306869

Are you sure that floated block-level elements are the best solution to this problem?

Often with CSS difficulties in my experience it turns out that the reason I can't see a way of doing the thing I want is that I have got caught in a tunnel-vision with regard to my markup ( thinking "how can I make these elements do this?" ) rather than going back and looking at what exactly it is I need to achieve and maybe reworking my html slightly to facilitate that.

the default text size of the textview

if you not used any of the below

TextAppearance.Small

TextAppearance.Medium

TextAppearance.Large

then the default size is 14sp

Yes it is Possible Will Den. we can run PHP code in tomcat server using it's own port number localhost:8080

here I'm writing some step which is so much useful for you.

How to install or run PHP on Tomcat 6 in windows

1. download and unzip PHP 5 to a directory, c:\php-5.2.6-Win32 - php-5.2.9-2-Win32.zip Download

2. download PECL 5.2.5 Win32 binaries - PECL 5.2.5 Win32 Download

3. rename php.ini-dist to php.ini in c:\php-5.2.6-Win32

4. Uncomment or add the line (remove semi-colon at the beginning) in php.ini: ;extension=php_java.dll

5. copy php5servlet.dll from PECL 5.2.5 to c:\php-5.2.6-Win32

6. copy php_java.dll from PECL 5.2.5 to c:\php-5.2.6-Win32\ext

7. copy php_java.jar from PECL 5.2.5 to tomcat\lib

8. create a directory named "php" (or what ever u like) in tomcat\webapps directory

9. copy phpsrvlt.jar from PECL 5.2.5 to tomcat\webapps\php\WEB-INF\lib

10. Unjar or unzip phpsrvlt.jar for unzip use winrar or winzip for unjar use : jar xfv phpsrvlt.jar

11. change both net\php\reflect.properties and net\php\servlet.properties to library=php5servlet

12. Recreate the jar file -> jar cvf php5srvlt.jar net/php/. PS: if the jar file doesnt run you have to add the Path to system variables for me I added C:\Program Files\Java\jdk1.6.0\bin; to System variables/Path

13. create web.xml in tomcat\webapps\php\WEB-INF with this content:

    <web-app version="2.4" 
      xmlns="http://java.sun.com/xml/ns/j2ee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "
      xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd ">
      <servlet>
        <servlet-name>php</servlet-name>
        <servlet-class>net.php.servlet</servlet-class>
      </servlet>
      <servlet>
        <servlet-name>php-formatter</servlet-name>
        <servlet-class>net.php.formatter</servlet-class>
      </servlet>
      <servlet-mapping>
        <servlet-name>php</servlet-name>
        <url-pattern>*.php</url-pattern>
      </servlet-mapping>
      <servlet-mapping>
        <servlet-name>php-formatter</servlet-name>
        <url-pattern>*.phps</url-pattern>
      </servlet-mapping>
    </web-app>
    

14. Add PHP path( c:\php-5.2.6-Win32) to your System or User Path in Windows enironment (Hint: Right-click and select Properties from My Computer

15. create test.php for testing under tomcat\webapps\php like

16. Restart tomcat

17. browse localhost:8080/php/test.php

I think you can use the overload of Regex.Replace to specify the maximum number of times to replace...

var regex = new Regex(Regex.Escape("o"));
var newText = regex.Replace("Hello World", "Foo", 1);

Try this ...

public class Solution {

  public static void main(String[] args) {
    long t = 1000;
    long sum = 0;

    for(int i = 1; i<t; i++){
            if(i%3 == 0 || i%5 == 0){
                sum = sum + i;
            }
        }
        System.out.println(sum);    
  }
}

No need to use these commands .. you can directly use the nexus web Interface in order to upload your JAR using GAV parameters.

So it is very simple.

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

In Eclipse, go to Window → Preferences → General → Network Connections. In the Active Provider combo box, choose "Manual". In the proxy entries table, for each entry click "Edit..." and supply your proxy host, port, username and password details.

You can avoid the OnItemSelectedListener() being called with a simple check: Store the current selection index in an integer variable and check within the onItemSelected(..) before doing anything.

E.g:

Spinner spnLocale;

spnLocale = (Spinner)findViewById(R.id.spnLocale);

int iCurrentSelection = spnLocale.getSelectedItemPosition();

spnLocale.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { 
    if (iCurrentSelection != i){
            // Your code here
    }
    iCurrentSelection = i;
    } 

    public void onNothingSelected(AdapterView<?> adapterView) {
        return;
    } 
}); 

Of cause the iCurrentSelection should be in object scope for this to work!

The code you're using is also going to include a fadeout effect. Is this what you want to achieve? If not, it might make more sense to just add the following INSIDE "Small.php".

<meta http-equiv="refresh" content="15" >

This adds a refresh every 15seconds to the small.php page which should mean if called by PHP into another page, only that "frame" will reload.

Let us know if it worked/solved your problem!?

If you are using Spark, use the following to get the Spark version:

spark-submit --version

or

Login to the Cloudera Manager and goto Hosts page then run inspect hosts in cluster

Here's the calling order:

1. app.config()
2. app.run()
3. directive's compile functions (if they are found in the dom)
4. app.controller()
5. directive's link functions (again, if found)

Here's a simple demo where you can watch each one executing (and experiment if you'd like).

From Angular's module docs:

Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.

Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.

One situation where run blocks are used is during authentications.

I modified @kolbyjack code to make it work for

http://website1/service/

with parameters

location ~ ^/service/?(.*) {
    return 301 http://service_url/$1$is_args$args;
}

I vote for:

await Promise.all([someCall(), anotherCall()]);

Be aware of the moment you call functions, it may cause unexpected result:

// Supposing anotherCall() will trigger a request to create a new User

if (callFirst) {
  await someCall();
} else {
  await Promise.all([someCall(), anotherCall()]); // --> create new User here
}

But following always triggers request to create new User

// Supposing anotherCall() will trigger a request to create a new User

const someResult = someCall();
const anotherResult = anotherCall(); // ->> This always creates new User

if (callFirst) {
  await someCall();
} else {
  const finalResult = [await someResult, await anotherResult]
}

Remove "SSLv2ClientHello" from the enabled protocols on the client SSLSocket or HttpsURLConnection.

The webserver is returning an http 500 error code. These errors generally happen when an exception in thrown on the webserver and there's no logic to catch it so it spits out an http 500 error. You can usually resolve the problem by placing try-catch blocks in your code.

Based on Xavier's answer, I wrote a Google chrome extension NuTake to add links to the Nuget.org package pages.

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

If you're using WPF and the previous answers don't help, you can retrieve the result using:

var result = MessageBox.Show("Message", "caption", MessageBoxButton.YesNo, MessageBoxImage.Question);

if (result == MessageBoxResult.Yes)
{
    // Do something
}

So here's the thing, Entity Framework is an implementation so despite the fact that it abstracts the complexity of database interaction, interacting directly is still tight coupling and that's why it's confusing to test.

Unit testing is about testing the logic of a function and each of its potential outcomes in isolation from any external dependencies, which in this case is the data store. In order to do that, you need to be able to control the behavior of the data store. For example, if you want to assert that your function returns false if the fetched user doesn't meet some set of criteria, then your [mocked] data store should be configured to always return a user that fails to meet the criteria, and vice versa for the opposite assertion.

With that said, and accepting the fact that EF is an implementation, I would likely favor the idea of abstracting a repository. Seem a bit redundant? It's not, because you are solving a problem which is isolating your code from the data implementation.

In DDD, the repositories only ever return aggregate roots, not DAO. That way, the consumer of the repository never has to know about the data implementation (as it shouldn't) and we can use that as an example of how to solve this problem. In this case, the object that is generated by EF is a DAO and as such, should be hidden from your application. This another benefit of the repository that you define. You can define a business object as its return type instead of the EF object. Now what the repo does is hide the calls to EF and maps the EF response to that business object defined in the repos signature. Now you can use that repo in place of the DbContext dependency that you inject into your classes and consequently, now you can mock that interface to give you the control that you need in order to test your code in isolation.

It's a bit more work and many thumb their nose at it, but it solves a real problem. There's an in-memory provider that was mentioned in a different answer that could be an option (I have not tried it), and its very existence is evidence of the need for the practice.

I completely disagree with the top answer because it sidesteps the real issue which is isolating your code and then goes on a tangent about testing your mapping. By all means test your mapping if you want to, but address the actual issue here and get some real code coverage.

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

You can execute parallel jobs in Powershell 2 using Background Jobs. Check out Start-Job and the other job cmdlets.

# Loop through the server list
Get-Content "ServerList.txt" | %{

  # Define what each job does
  $ScriptBlock = {
    param($pipelinePassIn) 
    Test-Path "\\$pipelinePassIn\c`$\Something"
    Start-Sleep 60
  }

  # Execute the jobs in parallel
  Start-Job $ScriptBlock -ArgumentList $_
}

Get-Job

# Wait for it all to complete
While (Get-Job -State "Running")
{
  Start-Sleep 10
}

# Getting the information back from the jobs
Get-Job | Receive-Job

Thanks @rofly, the full conversion from string to string is as follows:

time.strftime("%Y-%m-%d %H:%M:%S", 
              time.gmtime(time.mktime(time.strptime("2008-09-17 14:04:00", 
                                                    "%Y-%m-%d %H:%M:%S"))))

My summary of the time/calendar functions:

time.strptime
string --> tuple (no timezone applied, so matches string)

time.mktime
local time tuple --> seconds since epoch (always local time)

time.gmtime
seconds since epoch --> tuple in UTC

and

calendar.timegm
tuple in UTC --> seconds since epoch

time.localtime
seconds since epoch --> tuple in local timezone

With urlsearchparams:

const params = new URLSearchParams()
params.append('imageurl', http://www.image.com/?username=unknown&password=unknown)
return `http://www.foobar.com/foo?${params.toString()}`

You can use the lsvirtualenv, in which you have two options "long" or "brief":

"long" option is the default one, it searches for any hook you may have around this command and executes it, which takes more time.

"brief" just take the virtualenvs names and prints it.

brief usage:

$ lsvirtualenv -b

long usage:

$ lsvirtualenv -l

if you don't have any hooks, or don't even know what i'm talking about, just use "brief".

I had a similar issue, I was sending a POST request (using RESTClient plugin for Firefox) with data in the request body and was receiving the same message.

In my case this happened because I was trying to use HTTPS protocol in a local tomcat instance where HTTPS was not configured.

Use System.Windows.Forms.Timer.

private Timer timer1; 
public void InitTimer()
{
    timer1 = new Timer();
    timer1.Tick += new EventHandler(timer1_Tick);
    timer1.Interval = 2000; // in miliseconds
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    isonline();
}

You can call InitTimer() in Form1_Load().

try this to get the current date.You can also get current hour, minutes and seconds by using getters :

new Date(System.currentTimeMillis()).get....()

In the scikit-learn 'metrics' library there is a confusion_matrix method which gives you the desired output.

You can use any classifier that you want. Here I used the KNeighbors as example.

from sklearn import metrics, neighbors

clf = neighbors.KNeighborsClassifier()

X_test = ...
y_test = ...

expected = y_test
predicted = clf.predict(X_test)

conf_matrix = metrics.confusion_matrix(expected, predicted)

>>> print conf_matrix
>>>  [[1403   87]
     [  56 3159]]

The docs: http://scikit-learn.org/stable/modules/generated/sklearn.metrics.confusion_matrix.html#sklearn.metrics.confusion_matrix

I know its quite late but for anyone looking to do it from now on, I hope this answer proves of some help. If you have CodeRush Express (free version, and a 'must have') installed, it offers a simple way to change a project wide namespace. You just place your cursor on the namespace that you want to change and it shall display a smart tag (a little blue box) underneath namespace string. You can either click that box or press Ctrl + keys to see the Rename option. Select it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-)

You don't seem to have the stopwords corpus on your computer.

You need to start the NLTK Downloader and download all the data you need.

Open a Python console and do the following:

>>> import nltk
>>> nltk.download()
showing info http://nltk.github.com/nltk_data/

In the GUI window that opens simply press the 'Download' button to download all corpora or go to the 'Corpora' tab and only download the ones you need/want.

Application.Exit
    End

will work like a charm The "END" immediately terminates further execution while "Application.Exit" closes all forms and calls.

Best regrads,

Had the same problem. I was passing a non-const reference of custom class and the constructor complained (some tuple template errors). Replaced the reference with pointer and it worked.

This is a common way to do it:

long l = Long.parseLong(str);

There is also this method: Long.valueOf(str); Difference is that parseLong returns a primitive long while valueOf returns a new Long() object.

My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type.

You are sort of correct. You are allowed to initialize static const integrals in the class declaration but that is not a definition.

http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlcpp8a.doc/language/ref/cplr038.htm

Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line).

Any idea as to what's going on?

std::min takes its parameters by const reference. If it took them by value you'd not have this problem but since you need a reference you also need a definition.

Here's chapter/verse:

9.4.2/4 - If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

See Chu's answer for a possible workaround.

Well I think firstly keep whole main into try catch(or you can use as public static void main(String arg[]) throws IOException ) and then also use full path of file in which you are writing as

PrintWriter printWriter = new PrintWriter ("C:/Users/Me/Desktop/directory/file.txt");

all those directies like users,Me,Desktop,directory should be user made. java wont make directories own its own. it should be as

import java.io.*;
public class PrintWriterClass {

public static void main(String arg[]) throws IOException{
    PrintWriter pw = new PrintWriter("C:/Users/Me/Desktop/directory/file.txt");
    pw.println("hiiiiiii");
    pw.close();
}   

}

Add to this class in the .css file:

.row {
    margin-left: -20px;
    *zoom: 1;
    margin-top: 50px;
}

or make a new class and add it to the element

.rowSpecificFormName td {
    margin-top: 50px;
}

FirstOrDefault ?

Elem e = enumerable.FirstOrDefault();
//do something with e

Using plain javascript:

element.parentNode

In jQuery:

element.parent()

Your sort logic is wrong. This is the pseudo-code for bubble sort:

for i = 1:n,
    swapped = false
    for j = n:i+1, 
        if a[j] < a[j-1], 
            swap a[j,j-1]
            swapped = true
    ? invariant: a[1..i] in final position
    break if not swapped
end

See this sorting web site for good tutorial on all the various sorting methods.

Try this code:
HTML

<button type='button' id = 'rbutton_'+i onclick="disable(i)">Click me</button>

function

function disable(i){
    $("#rbutton_"+i).attr("disabled","disabled");
}

Other solution with jquery

$('button').click(function(){ 
    $(this).attr("disabled","disabled");
});

DEMO

Other solution with pure javascript

<button type='button' id = 'rbutton_1' onclick="disable(1)">Click me</button>

<script>
function disable(i){
 document.getElementById("rbutton_"+i).setAttribute("disabled","disabled");
}
</script>

Users user = bd.Users.Where(u=> u.UserAge > 21).Max(u => u.UserID); 

will not work because MAX returns the same type of variable that the field is so in this case is an INT not an User object.

This can be done by using a pointer, and allocating memory on the heap using malloc. Note that there is no way to later ask how big that memory block is. You have to keep track of the array size yourself.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char** argv)
{
  /* declare a pointer do an integer */
  int *data; 
  /* we also have to keep track of how big our array is - I use 50 as an example*/
  const int datacount = 50;
  data = malloc(sizeof(int) * datacount); /* allocate memory for 50 int's */
  if (!data) { /* If data == 0 after the call to malloc, allocation failed for some reason */
    perror("Error allocating memory");
    abort();
  }
  /* at this point, we know that data points to a valid block of memory.
     Remember, however, that this memory is not initialized in any way -- it contains garbage.
     Let's start by clearing it. */
  memset(data, 0, sizeof(int)*datacount);
  /* now our array contains all zeroes. */
  data[0] = 1;
  data[2] = 15;
  data[49] = 66; /* the last element in our array, since we start counting from 0 */
  /* Loop through the array, printing out the values (mostly zeroes, but even so) */
  for(int i = 0; i < datacount; ++i) {
    printf("Element %d: %d\n", i, data[i]);
  }
}

That's it. What follows is a more involved explanation of why this works :)

I don't know how well you know C pointers, but array access in C (like array[2]) is actually a shorthand for accessing memory via a pointer. To access the memory pointed to by data, you write *data. This is known as dereferencing the pointer. Since data is of type int *, then *data is of type int. Now to an important piece of information: (data + 2) means "add the byte size of 2 ints to the adress pointed to by data".

An array in C is just a sequence of values in adjacent memory. array[1] is just next to array[0]. So when we allocate a big block of memory and want to use it as an array, we need an easy way of getting the direct adress to every element inside. Luckily, C lets us use the array notation on pointers as well. data[0] means the same thing as *(data+0), namely "access the memory pointed to by data". data[2] means *(data+2), and accesses the third int in the memory block.
