You are looking for a web crawler. You can use JSoup to do this, here is basic example

As of today, there is no support on this function. However, I found a little hack on this one.

 imageView.setImageResource(R.drawable.ic_star_black_48dp);
 imageView.setTag(R.drawable.ic_star_black_48dp);

So if you want to get the ID of the view, just get it's tag.

if (imageView.getTag() != null) {
   int resourceID = (int) imageView.getTag();

   //
   // drawable id.
   //   
}

I use the following code with a form that has 2 buttons, one for exit and the other to start. A folder browser dialog and a save file dialog. Code is listed below and works on my system Windows10 (64):

using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Directory_List
{

    public partial class Form1 : Form
    {
        public string MyPath = "";
        public string MyFileName = "";
        public string str = "";

        public Form1()
        {
            InitializeComponent();
        }    
        private void cmdQuit_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }    
        private void cmdGetDirectory_Click(object sender, EventArgs e)
        {
            folderBrowserDialog1.ShowDialog();
            MyPath = folderBrowserDialog1.SelectedPath;    
            saveFileDialog1.ShowDialog();
            MyFileName = saveFileDialog1.FileName;    
            str = "Folder = " + MyPath + "\r\n\r\n\r\n";    
            DirectorySearch(MyPath);    
            var result = MessageBox.Show("Directory saved to Disk!", "", MessageBoxButtons.OK);
                Application.Exit();    
        }    
        public void DirectorySearch(string dir)
        {
                try
            {
                foreach (string f in Directory.GetFiles(dir))
                {
                    str = str + dir + "\\" + (Path.GetFileName(f)) + "\r\n";
                }    
                foreach (string d in Directory.GetDirectories(dir, "*"))
                {

                    DirectorySearch(d);
                }
                        System.IO.File.WriteAllText(MyFileName, str);

            }
            catch (System.Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
}

This code will help you out:-

- (NSString *)getFileName:(UIImageView *)imgView{
    NSString *imgName = [imgView image].accessibilityIdentifier;
    NSLog(@"%@",imgName);
    return imgName;
}

Use this as:-

NSString *currentImageName = [self getFileName:MyIImageView];

For modern browsers you should use:

document.getElementById("myspan").textContent="newtext";

While older browsers may not know textContent, it is not recommended to use innerHTML as it introduces an XSS vulnerability when the new text is user input (see other answers below for a more detailed discussion):

//POSSIBLY INSECURE IF NEWTEXT BECOMES A VARIABLE!!
document.getElementById("myspan").innerHTML="newtext";

You can use setdiff.

Given

a <- sample(1:10)
remove <- c(2, 3, 5)

Then

> a
 [1] 10  8  9  1  3  4  6  7  2  5
> setdiff(a, remove)
[1] 10  8  9  1  4  6  7

The above query returns the list of Object[]. So if you want to get the u.name and s.something from the list then you need to iterate and cast that values for the corresponding classes.

Building on jor's answer (which doesn't work for me):

substring=$(expr "$filename" : '.*_\([^_]*\)_.*')

In case of image stacks, I find it easier to use scikit-image to read, and matplotlib to show or save. I have handled 16-bit TIFF image stacks with the following code.

from skimage import io
import matplotlib.pyplot as plt

# read the image stack
img = io.imread('a_image.tif')
# show the image
plt.imshow(mol,cmap='gray')
plt.axis('off')
# save the image
plt.savefig('output.tif', transparent=True, dpi=300, bbox_inches="tight", pad_inches=0.0)

You can resize images using CSS just fine if you're modifying an image tag:

<img src="example.png" style="width:2em; height:3em;" />

You cannot scale a background-image property using CSS2, although you can try the CSS3 property background-size.

What you can do, on the other hand, is to nest an image inside a span. See the answer to this question: Stretch and scale CSS background

Edit: Whoops, didn't check your question tags before answering.

Check that you can actually connect to DB (have the driver placed? tested the conn when creating it?).

If so, try runnung those queries with F5

I know I'm am very late on this, but here some usefull samples:

'select the used cells in column 3 of worksheet wks

or

'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
    .value = .value
end with

To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like

 lngLast = cells(rows.count,3).end(xlUp).row

Deploy the app as exploded (project.war folder), add in your web.xml:

<web-app>

Update the web.xml time every-time you deploy (append blank line):

set PRJ_HOME=C:\Temp2\MyProject\src\main\webapp
set PRJ_CLSS_HOME=%PRJ_HOME%\WEB-INF\classes\com\myProject

You need to group on the grade field. This query should give you what your looking for in pretty much any database.

    Select Grade, CountofGrade / sum(CountofGrade) *100 
    from
    (
    Select Grade, Count(*) as CountofGrade
    From Grades
    Group By Grade) as sub
    Group by Grade

You should specify the system you're using.

You should be able to do something like this:

int radioButtonID = radioButtonGroup.getCheckedRadioButtonId();
View radioButton = radioButtonGroup.findViewById(radioButtonID);
int idx = radioButtonGroup.indexOfChild(radioButton);

If the RadioGroup contains other Views (like a TextView) then the indexOfChild() method will return wrong index.

To get the selected RadioButton text on the RadioGroup:

 RadioButton r = (RadioButton) radioButtonGroup.getChildAt(idx);
 String selectedtext = r.getText().toString();

I agree with Tom. In addition, to check the processes while performing Thread.Sleep, check the running processes. Something like:

bool found = 0;
while (!found)
{
    foreach (Process clsProcess in Process.GetProcesses())
        if (clsProcess.Name == Name)
            found = true;

    Thread.CurrentThread.Sleep(1000);
}

There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.

They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.

More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.

The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.

TCP never drops data so no, there is no way to indicate a server should forget about some segment.

Well I had the same problem that only seemed to happen for Firefox, and I couldn't use another JQuery command except for .load() since I was modifying the front-end on exisitng PHP files...

Anyways, after using the .load() command, I embedded my JQuery script within the external HTML that was getting loaded in, and it seemed to work. I don't understand why the JS that I loaded at the top of the main document didn't work for the new content however...

For anything with requests to URLs you might want to check out requests. For JSON in particular:

>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...

To change DatePicker colors (calendar mode) at application level define below properties.

<style name="MyAppTheme" parent="Theme.AppCompat.Light">
    <item name="colorAccent">#ff6d00</item>
    <item name="colorControlActivated">#33691e</item>
    <item name="android:selectableItemBackgroundBorderless">@color/colorPrimaryDark</item>
    <item name="colorControlHighlight">#d50000</item>
</style>

See http://www.zoftino.com/android-datepicker-example for other DatePicker custom styles

If you've tried everything mentioned here and it didn't work, make sure you also have added angular material to your project. If not, just run the following command in the terminal to add it:

ng add @angular/material

After it successfully gets added, wait for the project to get refreshed, and the error will be automatically gone.

Please remove . from your target it should be a id

<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>

Also you have to give your modal id like below

<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">

Here is the solution in a fiddle.

Set style= "display:none;". By setting visible=false, it will not render button in the browser. Thus,client side script wont execute.

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />

html markup should be

<button id="btnsave" onclick="fncsave()">Save</button>

Change javascript to

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.ClientID %>').click();
     }
</script>

You may use this -

(data_type)log10(variable_name)+1

ex:

len = (int)log10(number)+1;

If the double is a Double with capital D (a boxed primitive value):

Double d = 4.97542;
int i = (int) d.doubleValue();

// or directly:
int i2 = d.intValue();

If the double is already a primitive double, then you simply cast it:

double d = 4.97542;
int i = (int) d;

Additional to the answer of Akshit Soota: it is importand to explicitly set the height of each parent element, also of the table and column if any:

<body style="margin: 0px; padding:0px; height: 100%; overflow:hidden; ">
<form id="form1" runat="server" style=" height: 100%">
<div style=" height: 100%">


    <table style="width: 100%; height: 100%" cellspacing="0"  cellpadding="0">
        <tr>
            <td valign="top" align="left" height="100%">
                <iframe style="overflow:hidden;height:100%;width:100%;margin: 0px; padding:0px;" 
                        width="100%" height="100%" frameborder="0" scrolling="no"
                        src="http://www.youraddress.com" ></iframe> 
            </td>

I would always use sp_executesql these days, all it really is is a wrapper for EXEC which handles parameters & variables.

However do not forget about OPTION RECOMPILE when tuning queries on very large databases, especially where you have data spanned over more than one database and are using a CONSTRAINT to limit index scans.

Unless you use OPTION RECOMPILE, SQL server will attempt to create a "one size fits all" execution plan for your query, and will run a full index scan each time it is run.

This is much less efficient than a seek, and means it is potentially scanning entire indexes which are constrained to ranges which you are not even querying :@

The reason why Python base environment is unable to import Tensorflow is that Anaconda does not store the tensorflow package in the base environment.

create a new separate environment in Anaconda dedicated to TensorFlow as follows:

conda create -n newenvt anaconda python=python_version

replace python_version by your python version

activate the new environment as follows:

activate newenvt

Then install tensorflow into the new environment (newenvt) as follows:

conda install tensorflow

Now you can check it by issuing the following python code and it will work fine.

import tensorflow

if (charCode > 47 && charCode < 58) {
    document.getElementById("error").innerHTML = "*Please Enter Your Name Only";
    document.getElementById("fullname").focus();
    document.getElementById("fullname").style.borderColor = 'red';
    return false;
} else {
    document.getElementById("error").innerHTML = "";
    document.getElementById("fullname").style.borderColor = '';
    return true;
}

Two ways to position a tag in the middle of screen or its parent tag:

Using positions:

Set the parent tag position to relative (if the target tag has a parent tag) and then set the target tag style like this:

#center {
  ...  
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

Using flex:

The parent tag style should looks like this:

#parent-tag {
  display: flex;
  align-items: center;
  justify-content: center;
}

One idea would be to winsorize the data in a two-pass procedure:

1. run a first pass, learn what the bounds are, e.g. cut of at given percentile, or N standard deviation above the mean, or ...

2. in a second pass, set the values beyond the given bound to the value of that bound

I should stress that this is an old-fashioned method which ought to be dominated by more modern robust techniques but you still come across it a lot.

Press Alt to make the menu visible and then in the View menu choose Appearance -> Show Menu Bar.

macOS: If you are in Full-Screen mode you can either move the cursor to the top of the screen to see the menu, or you can exit Full-Screen using Ctrl+Cmd+F, or ^?F in alien's script.

This link will help you in understanding pass by reference in C#. Basically,when an object of reference type is passed by value to an method, only methods which are available on that object can modify the contents of object.

For example List.sort() method changes List contents but if you assign some other object to same variable, that assignment is local to that method. That is why myList remains unchanged.

If we pass object of reference type by using ref keyword then we can assign some other object to same variable and that changes entire object itself.

(Edit: this is the updated version of the documentation linked above.)

Use ProcessBuilder to separate commands and arguments instead of spaces. This should work regardless of shell used:

        commands.add("/bin/cat");
        //Add arguments
        commands.add("/home/narek/pk.txt");
        System.out.println(commands);

        //Run macro on target
        ProcessBuilder pb = new ProcessBuilder(commands);
        pb.directory(new File("/home/narek"));
        pb.redirectErrorStream(true);
        Process process = pb.start();

        //Read output
        StringBuilder out = new StringBuilder();
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null, previous = null;
        while ((line = br.readLine()) != null)
            if (!line.equals(previous)) {
                previous = line;
                out.append(line).append('\n');
                System.out.println(line);
            }

        //Check result
        if (process.waitFor() == 0) {
            System.out.println("Success!");
            System.exit(0);
        }

        //Abnormal termination: Log command parameters and output and throw ExecutionException
        System.err.println(commands);
        System.err.println(out.toString());
        System.exit(1);
    }
}

I originally used @Aliceljm's answer for a file upload project I was working on, but recently ran into an issue where a file was 0.98kb but being read as 1.02mb. Here's the updated code I'm now using.

function formatBytes(bytes){
  var kb = 1024;
  var ndx = Math.floor( Math.log(bytes) / Math.log(kb) );
  var fileSizeTypes = ["bytes", "kb", "mb", "gb", "tb", "pb", "eb", "zb", "yb"];

  return {
    size: +(bytes / kb / kb).toFixed(2),
    type: fileSizeTypes[ndx]
  };
}

The above would then be called after a file was added like so

// In this case `file.size` equals `26060275` 
formatBytes(file.size);
// returns `{ size: 24.85, type: "mb" }`

Granted, Windows reads the file as being 24.8mb but I'm fine with the extra precision.

See C# specification. There are three types of division operators

• Integer division
• Floating-point division
• Decimal division

In your case we have Integer division, with following rules applied:

The division rounds the result towards zero, and the absolute value of the result is the largest possible integer that is less than the absolute value of the quotient of the two operands. The result is zero or positive when the two operands have the same sign and zero or negative when the two operands have opposite signs.

I think the reason why C# use this type of division for integers (some languages return floating result) is hardware - integers division is faster and simpler.

In 2019, having this works for me on Chrome, Firefox and Opera (after many other unsuccessful attempts):

.content {
    margin: 0;
    -webkit-column-break-inside: avoid;
    break-inside: avoid;
    break-inside: avoid-column;
}

li {
    -webkit-column-break-inside:avoid;
       -moz-column-break-inside:avoid;
            column-break-inside:avoid;
           break-inside: avoid-column;
             page-break-inside: avoid;
}

os.path works in a funny way. It looks like os should be a package with a submodule path, but in reality os is a normal module that does magic with sys.modules to inject os.path. Here's what happens:

• When Python starts up, it loads a bunch of modules into sys.modules. They aren't bound to any names in your script, but you can access the already-created modules when you import them in some way.

  • sys.modules is a dict in which modules are cached. When you import a module, if it already has been imported somewhere, it gets the instance stored in sys.modules.

• os is among the modules that are loaded when Python starts up. It assigns its path attribute to an os-specific path module.

• It injects sys.modules['os.path'] = path so that you're able to do "import os.path" as though it was a submodule.

I tend to think of os.path as a module I want to use rather than a thing in the os module, so even though it's not really a submodule of a package called os, I import it sort of like it is one and I always do import os.path. This is consistent with how os.path is documented.

Incidentally, this sort of structure leads to a lot of Python programmers' early confusion about modules and packages and code organization, I think. This is really for two reasons

1. If you think of os as a package and know that you can do import os and have access to the submodule os.path, you may be surprised later when you can't do import twisted and automatically access twisted.spread without importing it.

2. It is confusing that os.name is a normal thing, a string, and os.path is a module. I always structure my packages with empty __init__.py files so that at the same level I always have one type of thing: a module/package or other stuff. Several big Python projects take this approach, which tends to make more structured code.

If you want a solution that also works in /bin/sh try

first_arg="$1"
shift
echo First argument: "$first_arg"
echo Remaining arguments: "$@"

shift [n] shifts the positional parameters n times. A shift sets the value of $1 to the value of $2, the value of $2 to the value of $3, and so on, decreasing the value of $# by one.

This can be done elegantly with Ray, a system that allows you to easily parallelize and distribute your Python code.

To parallelize your example, you'd need to define your functions with the @ray.remote decorator, and then invoke them with .remote.

import ray

ray.init()

# Define functions you want to execute in parallel using 
# the ray.remote decorator.
@ray.remote
def func1():
    print("Working")

@ray.remote
def func2():
    print("Working")

# Execute func1 and func2 in parallel.
ray.get([func1.remote(), func2.remote()])

If func1() and func2() return results, you need to rewrite the above code a bit, by replacing ray.get([func1.remote(), func2.remote()]) with:

ret_id1 = func1.remote()
ret_id2 = func1.remote()
ret1, ret2 = ray.get([ret_id1, ret_id2])

There are a number of advantages of using Ray over the multiprocessing module or using multithreading. In particular, the same code will run on a single machine as well as on a cluster of machines.

For more advantages of Ray see this related post.

SELECT group, COUNT(*) FROM table GROUP BY group ORDER BY group

or to order by the count

SELECT group, COUNT(*) AS count FROM table GROUP BY group ORDER BY count DESC

As far as I know, if an exception is not caught by your script, it will be interrupted.

        link: function(scope, element, attrs, screenCtrl) {
            scope.screenCtrl = screenCtrl
        }
    }
})

.directive('widget', function() {
    return {
        scope: true,
        require: "^component",
        link: function(scope, element, attrs, componentCtrl) {
            scope.widgetIt = function() {
                componentCtrl.componentFunction();
            };
        }
    }
})


//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});

function MyCtrl($scope) {
    $scope.name = 'Superhero';
}

Other alternative: Pure

I use it and it has helped me a lot. An example shown on their website:

HTML

<div class="who">
</div>

JSON

{
  "who": "Hello Wrrrld"
}

Result

<div class="who">
  Hello Wrrrld
</div>

>>> "{:.1f}".format(45.34531)
'45.3'

Or use the builtin round:

>>> round(45.34531, 1)
45.299999999999997

This works for me, and in this case was a remote connection: Note: The port was IMPORTANT for me

$dsn = "sqlsrv:Server=server.dyndns.biz,1433;Database=DBNAME";
$conn = new PDO($dsn, "root", "P4sw0rd");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$sql = "SELECT * FROM Table";

foreach ($conn->query($sql) as $row) {
    print_r($row);
} 

To count number of tables just do this:

USE your_db_name;    -- set database
SHOW TABLES;         -- tables lists
SELECT FOUND_ROWS(); -- number of tables

Sometimes easy things will do the work.

I will provide a detailed differences between Visual Studio and Visual Studio Code below.

If you really look at it the most obvious difference is that .NET has been split into two:

• .NET Core (Mac, Linux, and Windows)
• .NET Framework (Windows only)

All native user interface technologies (Windows Presentation Foundation, Windows Forms, etc.) are part of the framework, not the core.

The "Visual" in Visual Studio (from Visual Basic) was largely synonymous with visual UI (drag & drop WYSIWYG) design, so in that sense, Visual Studio Code is Visual Studio without the Visual!

The second most obvious difference is that Visual Studio tends to be oriented around projects & solutions.

Visual Studio Code:

• It's a lightweight source code editor which can be used to view, edit, run, and debug source code for applications.
• Simply it is Visual Studio without the Visual UI, majorly a superman’s text-editor.
• It is mainly oriented around files, not projects.
• It does not have any scaffolding support.
• It is a competitor of Sublime Text or Atom on Electron.
• It is based on the Electron framework, which is used to build cross platform desktop application using web technologies.
• It does not have support for Microsoft's version control system; Team Foundation Server.
• It has limited IntelliSense for Microsoft file types and similar features.
• It is mainly used by developers on a Mac who deal with client-side technologies (HTML, JavaScript, and CSS).

Visual Studio:

• As the name indicates, it is an IDE, and it contains all the features required for project development. Like code auto completion, debugger, database integration, server setup, configurations, and so on.
• It is a complete solution mostly used by and for .NET related developers. It includes everything from source control to bug tracker to deployment tools, etc. It has everything required to develop.
• It is widely used on .NET related projects (though you can use it for other things). The community version is free, but if you want to make most of it then it is not free.

• Visual Studio is aimed to be the world’s best IDE (integrated development environment), which provide full stack develop toolsets, including a powerful code completion component called IntelliSense, a debugger which can debug both source code and machine code, everything about ASP.NET development, and something about SQL development.

• In the latest version of Visual Studio, you can develop cross-platform application without leaving the IDE. And Visual Studio takes more than 8 GB disk space (according to the components you select).

• In brief, Visual Studio is an ultimate development environment, and it’s quite heavy.

UPDATE "TABLE"

You want a config.site file. Try:

$ mkdir -p ~/local/share
$ cat << EOF > ~/local/share/config.site
CPPFLAGS=-I$HOME/local/include
LDFLAGS=-L$HOME/local/lib
...
EOF

Whenever you invoke an autoconf generated configure script with --prefix=$HOME/local, the config.site will be read and all the assignments will be made for you. CPPFLAGS and LDFLAGS should be all you need, but you can make any other desired assignments as well (hence the ... in the sample above). Note that -I flags belong in CPPFLAGS and not in CFLAGS, as -I is intended for the pre-processor and not the compiler.

Use the subprocess module as mentioned above.

I use it like this:

subprocess.call(["notepad"])

I find the adding <br> does what is wanted.

All the answers are good. The java8+ have these patterns for parsing and formatting timezone: V, z, O, X, x, Z.

Here's they are, for parsing, according to rules from the documentation :

   Symbol  Meaning                     Presentation      Examples
   ------  -------                     ------------      -------
   V       time-zone ID                zone-id           America/Los_Angeles; Z; -08:30
   z       time-zone name              zone-name         Pacific Standard Time; PST
   O       localized zone-offset       offset-O          GMT+8; GMT+08:00; UTC-08:00;
   X       zone-offset 'Z' for zero    offset-X          Z; -08; -0830; -08:30; -083015; -08:30:15;
   x       zone-offset                 offset-x          +0000; -08; -0830; -08:30; -083015; -08:30:15;
   Z       zone-offset                 offset-Z          +0000; -0800; -08:00;

But how about formatting? Here's a sample for a date (assuming ZonedDateTime) that show these patters behavior for different formatting patters:

// The helper function:
static void printInPattern(ZonedDateTime dt, String pattern) {
    System.out.println(pattern + ": " + dt.format(DateTimeFormatter.ofPattern(pattern)));
}        

// The date:
String strDate = "2020-11-03 16:40:44 America/Los_Angeles";
DateTimeFormatter format = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss zzzz");
ZonedDateTime dt = ZonedDateTime.parse(strDate, format);
// 2020-11-03T16:40:44-08:00[America/Los_Angeles]

// Rules:
// printInPattern(dt, "V");     // exception!
printInPattern(dt, "VV");       // America/Los_Angeles
// printInPattern(dt, "VVV");   // exception!
// printInPattern(dt, "VVVV");  // exception!
printInPattern(dt, "z");        // PST
printInPattern(dt, "zz");       // PST
printInPattern(dt, "zzz");      // PST
printInPattern(dt, "zzzz");     // Pacific Standard Time
printInPattern(dt, "O");        // GMT-8
// printInPattern(dt, "OO");    // exception!
// printInPattern(dt, "OO0");   // exception!
printInPattern(dt, "OOOO");     // GMT-08:00
printInPattern(dt, "X");        // -08
printInPattern(dt, "XX");       // -0800
printInPattern(dt, "XXX");      // -08:00
printInPattern(dt, "XXXX");     // -0800
printInPattern(dt, "XXXXX");    // -08:00
printInPattern(dt, "x");        // -08
printInPattern(dt, "xx");       // -0800
printInPattern(dt, "xxx");      // -08:00
printInPattern(dt, "xxxx");     // -0800
printInPattern(dt, "xxxxx");    // -08:00
printInPattern(dt, "Z");        // -0800
printInPattern(dt, "ZZ");       // -0800
printInPattern(dt, "ZZZ");      // -0800
printInPattern(dt, "ZZZZ");     // GMT-08:00
printInPattern(dt, "ZZZZZ");    // -08:00

In the case of positive offset the + sign character is used everywhere(where there is - now) and never omitted.

This well works for new java.time types. If you're about to use these for java.util.Date or java.util.Calendar - not all going to work as those types are broken(and so marked as deprecated, please don't use them)

That is not possible, but you can add an anonymous initializer like this:

final int anInt = ...;
Object a = new Class1()
{
  {
    System.out.println(anInt);
  }

  void someNewMethod() {
  }
};

Don't forget final on declarations of local variables or parameters used by the anonymous class, as i did it for anInt.

The classpath is the place(s) where the java compiler (command: javac) and the JVM (command:java) look in order to find classes which your application reference. What does it mean for an application to reference another class ? In simple words it means to use that class somewhere in its code:

Example:

public class MyClass{
    private AnotherClass referenceToAnotherClass;
    .....
}

When you try to compile this (javac) the compiler will need the AnotherClass class. The same when you try to run your application: the JVM will need the AnotherClass class. In order to to find this class the javac and the JVM look in a particular (set of) place(s). Those places are specified by the classpath which on linux is a colon separated list of directories (directories where the javac/JVM should look in order to locate the AnotherClass when they need it).

So in order to compile your class and then to run it, you should make sure that the classpath contains the directory containing the AnotherClass class. Then you invoke it like this:

javac -classpath "dir1;dir2;path/to/AnotherClass;...;dirN" MyClass.java //to compile it
java -classpath "dir1;dir2;path/to/AnotherClass;...;dirN" MyClass //to run it

Usually classes come in the form of "bundles" called jar files/libraries. In this case you have to make sure that the jar containing the AnotherClass class is on your classpaht:

javac -classpath "dir1;dir2;path/to/jar/containing/AnotherClass;...;dirN" MyClass.java //to compile it
java -classpath ".;dir1;dir2;path/to/jar/containing/AnotherClass;...;dirN" MyClass //to run it

In the examples above you can see how to compile a class (MyClass.java) located in the working directory and then run the compiled class (Note the "." at the begining of the classpath which stands for current directory). This directory has to be added to the classpath too. Otherwise, the JVM won't be able to find it.

If you have your class in a jar file, as you specified in the question, then you have to make sure that jar is in the classpath too , together with the rest of the needed directories.

Example:

java -classpath ".;dir1;dir2;path/to/jar/containing/AnotherClass;path/to/MyClass/jar...;dirN" MyClass //to run it

or more general (assuming some package hierarchy):

java -classpath ".;dir1;dir2;path/to/jar/containing/AnotherClass;path/to/MyClass/jar...;dirN" package.subpackage.MyClass //to run it

In order to avoid setting the classpath everytime you want to run an application you can define an environment variable called CLASSPATH.

In linux, in command prompt:

export CLASSPATH="dir1;dir2;path/to/jar/containing/AnotherClass;...;dirN" 

or edit the ~/.bashrc and add this line somewhere at the end;

However, the class path is subject to frequent changes so, you might want to have the classpath set to a core set of dirs, which you need frequently and then extends the classpath each time you need for that session only. Like this:

export CLASSPATH=$CLASSPATH:"new directories according to your current needs" 

Split a string delimited by characters and return all non-empty elements.

var names = ",Brian,Joe,Chris,,,";
var charSeparator = ",";
var result = names.Split(charSeparator, StringSplitOptions.RemoveEmptyEntries);

https://docs.microsoft.com/en-us/dotnet/api/system.string.split?view=netframework-4.8

I suggest taking a look at Lodash; it has a lot of great utility functions.

For example pick() would be exactly what you seek:

var subset = _.pick(elmo, ['color', 'height']);

fiddle

Razz's solution would work for the .hide() and .show() methods but would not work for the .toggle() method.

Depending upon the scenario, having a css class .inline_block { display: inline-block; } and calling $(element).toggleClass('inline_block') solves the problem for me.

jwilner's response is spot on. I was exploring to see if there's a faster option, since in my experience, summing flat arrays is (strangely) faster than counting. This code seems faster:

df.isnull().values.any()

import numpy as np
import pandas as pd
import perfplot


def setup(n):
    df = pd.DataFrame(np.random.randn(n))
    df[df > 0.9] = np.nan
    return df


def isnull_any(df):
    return df.isnull().any()


def isnull_values_sum(df):
    return df.isnull().values.sum() > 0


def isnull_sum(df):
    return df.isnull().sum() > 0


def isnull_values_any(df):
    return df.isnull().values.any()


perfplot.save(
    "out.png",
    setup=setup,
    kernels=[isnull_any, isnull_values_sum, isnull_sum, isnull_values_any],
    n_range=[2 ** k for k in range(25)],
)

df.isnull().sum().sum() is a bit slower, but of course, has additional information -- the number of NaNs.

SQLAlchemy is more full-featured and powerful (uses the DataMapper pattern). Django ORM has a cleaner syntax and is easier to write for (ActiveRecord pattern). I don't know about performance differences.

SQLAlchemy also has a declarative layer that hides some complexity and gives it a ActiveRecord-style syntax more similar to the Django ORM.

I wouldn't worry about Django being "too heavy." It's decoupled enough that you can use the ORM if you want without having to import the rest.

That said, if I were already using CherryPy for the web layer and just needed an ORM, I'd probably opt for SQLAlchemy.

i am using NetBeans IDE 7.2.1 as my developer environmental and there you have an option to configure the JForm properties.

in the JForm Properties go to the 'Code' tab and configure the 'Generate Center'. you will need first to set the Form Size Policy to 'Generate Resize Code'.

Actually there is a simpler way to do this, just:

if ($("#input").is(':empty')) {
console.log('empty');
} else {
console.log('not empty');
}

I had some columns that had multiple default constraints created, so I create the following stored procedure:

CREATE PROCEDURE [dbo].[RemoveDefaultConstraints] @table_name nvarchar(256), @column_name nvarchar(256)
AS
BEGIN

    DECLARE @ObjectName NVARCHAR(100)

    START: --Start of loop
    SELECT 
        @ObjectName = OBJECT_NAME([default_object_id]) 
    FROM 
        SYS.COLUMNS
    WHERE 
        [object_id] = OBJECT_ID(@table_name) 
        AND [name] = @column_name;

    -- Don't drop the constraint unless it exists
    IF @ObjectName IS NOT NULL
    BEGIN
        EXEC ('ALTER TABLE '+@table_name+' DROP CONSTRAINT ' + @ObjectName)
        GOTO START; --Used to loop in case of multiple default constraints
    END
END
GO

-- How to run the stored proc.  This removes the default constraint(s) for the enabled column on the User table.
EXEC [dbo].[RemoveDefaultConstraints] N'[dbo].[User]', N'enabled'
GO

-- If you hate the proc, just get rid of it
DROP PROCEDURE [dbo].[RemoveDefaultConstraints]
GO

See if your .exe file is in your antivirus quarantine

Solutions:

1. Download the adt-bundle again from https://developer.android.com/tools/sdk.
2. Open the Zip File.
3. Copy the missing .exe Files From the Folder \sdk\tools.
4. Past the Copied Files in Your Android\sdk\tools Directory.

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

Shutdown(1) , forces the socket no to send any more data

This is usefull in

1- Buffer flushing

2- Strange error detection

3- Safe guarding

Let me explain more , when you send a data from A to B , it's not guaranteed to be sent to B , it's only guaranteed to be sent to the A os buffer , which in turn sends it to the B os buffer

So by calling shutdown(1) on A , you flush A's buffer and an error is raised if the buffer is not empty ie: data has not been sent to the peer yet

Howoever this is irrevesable , so you can do that after you completely sent all your data and you want to be sure that it's atleast at the peer os buffer

Here is an example. You enter a number (or whatever) in the textbox and press "add" to put it in the array. Then you press "show" to show the array items as elements.

<script type="text/javascript">

var arr = [];

function add() {
   var inp = document.getElementById('num');
   arr.push(inp.value);
   inp.value = '';
}

function show() {
   var html = '';
   for (var i=0; i<arr.length; i++) {
      html += '<div>' + arr[i] + '</div>';
   }
   var con = document.getElementById('container');
   con.innerHTML = html;
}

</script>

<input type="text" id="num" />
<input type="button" onclick="add();" value="add" />
<br />
<input type="button" onclick="show();" value="show" />
<div id="container"></div>

The root cause of this issue can be in the regional settings - DB waiting for YYYY-MM-DD while an app sents, for example, DD-MM-YYYY (Russian locale format) as it was in my case. All I did - change locale format from Russian to English (United States) and voilà.

With support for C++11 initializer lists it is very easy:

#include <iostream>
#include <vector>
#include <string>
using namespace std;

using Strings = vector<string>;

void foo( Strings const& strings )
{
    for( string const& s : strings ) { cout << s << endl; }
}

auto main() -> int
{
    foo( Strings{ "hi", "there" } ); 
}

Lacking that (e.g. for Visual C++ 10.0) you can do things like this:

#include <iostream>
#include <vector>
#include <string>
using namespace std;

typedef vector<string> Strings;

void foo( Strings const& strings )
{
    for( auto it = begin( strings );  it != end( strings );  ++it )
    {
        cout << *it << endl;
    }
}

template< class Elem >
vector<Elem>& r( vector<Elem>&& o ) { return o; }

template< class Elem, class Arg >
vector<Elem>& operator<<( vector<Elem>& v, Arg const& a )
{
    v.push_back( a );
    return v;
}

int main()
{
    foo( r( Strings() ) << "hi" << "there" ); 
}

HTML

Since <input> element displays only value of value attribute, we have to manipulate only it:

<input type="submit" class="btn fa-input" value="&#xf043; Input">

I'm using  entity here, which corresponds to the U+F043, the Font Awesome's 'tint' symbol.

CSS

Then we have to style it to use the font:

.fa-input {
  font-family: FontAwesome, 'Helvetica Neue', Helvetica, Arial, sans-serif;
}

Which will give us the tint symbol in Font Awesome and the other text in the appropriate font.

However, this control will not be pixel-perfect, so you might have to tweak it by yourself.

This is a preprocessor directive that can be used to turn on or off certain features.

It is of two types #pragma startup, #pragma exit and #pragma warn.

#pragma startup allows us to specify functions called upon program startup.

#pragma exit allows us to specify functions called upon program exit.

#pragma warn tells the computer to suppress any warning or not.

Many other #pragma styles can be used to control the compiler.

you can use this CSS

p {
  width: min-content;
  min-width: 100%;
}

Updating NPM to the latest version worked for me:

npm install npm@latest -g

You could also provide a link to the page after login and have it auto redirect using javascript after 10 seconds.

Service

• Invoke by startService()
• Triggered from any Thread
• Runs on Main Thread
• May block main (UI) thread. Always use thread within service for long task
• Once task has done, it is our responsibility to stop service by calling stopSelf() or stopService()

IntentService

• It performs long task usually no communication with main thread if communication is needed then it is done by Handler or BroadcastReceiver
• Invoke via Intent
• Triggered from Main Thread
• Runs on the separate thread
• Can't run the task in parallel and multiple intents are Queued on the same worker thread.

In that case, we can do the following

$('selected').unbind('click').bind('click', function (e) {
  do_something();
});

I had the event firing two times initially, when the page get refreshed it fires four times. It was after many fruitless hours before I figured out with a google search.

I must also say that the code initially was working until I started using the JQueryUI accordion widget.

I know this question is quite old, but here's a library that encapsulates the ProcessBuilder api.

Regshot deserves a mention here. It scans and takes a snapshot of all registry settings, then you run it again at a later time to compare with the original snapshot, and it shows you all the keys and values that have changed.

Best answer is just removeAttribute

element.removeAttribute("disabled");

The really quick and dirty way is to point to a local file:

<dependency>
      <groupId>sampleGroupId</groupId>  
       <artifactId>sampleArtifactId</artifactId>  
       <version>1.0</version> 
      <scope>system</scope>
      <systemPath>C:\DEV\myfunnylib\yourJar.jar</systemPath>
</dependency>

However this will only live on your machine (obviously), for sharing it usually makes sense to use a proper m2 archive (nexus/artifactory) or if you do not have any of these or don't want to set one up a local maven structured archive and configure a "repository" in your pom:

local:

<repositories>
    <repository>
        <id>my-local-repo</id>
        <url>file://C:/DEV//mymvnrepo</url>
    </repository>
</repositories>

remote:

<repositories>
    <repository>
        <id>my-remote-repo</id>
        <url>http://192.168.0.1/whatever/mavenserver/youwant/repo</url>
    </repository>
</repositories>

1. Performance:

Assume your where clause is like this:

WHERE NAME='JON'

If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.

2. Character set:

If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.

I just had a similar issue. Running Process Explorer showed that another program (Notepad++) had a file handle to a folder that SVN had tried to delete. When I closed Notepad++, "Clean Up" was able to run successfully.

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

For the mocks initialization, using the runner or the MockitoAnnotations.initMocks are strictly equivalent solutions. From the javadoc of the MockitoJUnitRunner :

JUnit 4.5 runner initializes mocks annotated with Mock, so that explicit usage of MockitoAnnotations.initMocks(Object) is not necessary. Mocks are initialized before each test method.

The first solution (with the MockitoAnnotations.initMocks) could be used when you have already configured a specific runner (SpringJUnit4ClassRunner for example) on your test case.

The second solution (with the MockitoJUnitRunner) is the more classic and my favorite. The code is simpler. Using a runner provides the great advantage of automatic validation of framework usage (described by @David Wallace in this answer).

Both solutions allows to share the mocks (and spies) between the test methods. Coupled with the @InjectMocks, they allow to write unit tests very quickly. The boilerplate mocking code is reduced, the tests are easier to read. For example:

@RunWith(MockitoJUnitRunner.class)
public class ArticleManagerTest {

    @Mock private ArticleCalculator calculator;
    @Mock(name = "database") private ArticleDatabase dbMock;
    @Spy private UserProvider userProvider = new ConsumerUserProvider();

    @InjectMocks private ArticleManager manager;

    @Test public void shouldDoSomething() {
        manager.initiateArticle();
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        manager.finishArticle();
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: The code is minimal

Cons: Black magic. IMO it is mainly due to the @InjectMocks annotation. With this annotation "you loose the pain of code" (see the great comments of @Brice)

The third solution is to create your mock on each test method. It allow as explained by @mlk in its answer to have "self contained test".

public class ArticleManagerTest {

    @Test public void shouldDoSomething() {
        // given
        ArticleCalculator calculator = mock(ArticleCalculator.class);
        ArticleDatabase database = mock(ArticleDatabase.class);
        UserProvider userProvider = spy(new ConsumerUserProvider());
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.initiateArticle();

        // then 
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        // given
        ArticleCalculator calculator = mock(ArticleCalculator.class);
        ArticleDatabase database = mock(ArticleDatabase.class);
        UserProvider userProvider = spy(new ConsumerUserProvider());
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.finishArticle();

        // then
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: You clearly demonstrate how your api works (BDD...)

Cons: there is more boilerplate code. (The mocks creation)

My recommandation is a compromise. Use the @Mock annotation with the @RunWith(MockitoJUnitRunner.class), but do not use the @InjectMocks :

@RunWith(MockitoJUnitRunner.class)
public class ArticleManagerTest {

    @Mock private ArticleCalculator calculator;
    @Mock private ArticleDatabase database;
    @Spy private UserProvider userProvider = new ConsumerUserProvider();

    @Test public void shouldDoSomething() {
        // given
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.initiateArticle();

        // then 
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        // given
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.finishArticle();

        // then 
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: You clearly demonstrate how your api works (How my ArticleManager is instantiated). No boilerplate code.

Cons: The test is not self contained, less pain of code

There are two steps you need to take.

First, you need to put the PDF in an iframe.

  <iframe id="pdf" name="pdf" src="document.pdf"></iframe>

To print the iframe you can look at the answers here:

Javascript Print iframe contents only

If you want to print the iframe automatically after the PDF has loaded, you can add an onload handler to the <iframe>:

  <iframe onload="isLoaded()" id="pdf" name="pdf" src="document.pdf"></iframe>

the loader can look like this:

function isLoaded()
{
  var pdfFrame = window.frames["pdf"];
  pdfFrame.focus();
  pdfFrame.print();
}

This will display the browser's print dialog, and then print just the PDF document itself. (I personally use the onload handler to enable a "print" button so the user can decide to print the document, or not).

I'm using this code pretty much verbatim in Safari and Chrome, but am yet to try it on IE or Firefox.

You can use the default traceroute command for this purpose, then there will be nothing to install.

traceroute -T -p 9100 <IP address/hostname>

The -T argument is required so that the TCP protocol is used instead of UDP.

In the rare case when traceroute isn't available, you can also use ncat.

nc -Czvw 5 <IP address/hostname> 9100

Integrated application pool mode

When an application pool is in Integrated mode, you can take advantage of the integrated request-processing architecture of IIS and ASP.NET. When a worker process in an application pool receives a request, the request passes through an ordered list of events. Each event calls the necessary native and managed modules to process portions of the request and to generate the response.

There are several benefits to running application pools in Integrated mode. First the request-processing models of IIS and ASP.NET are integrated into a unified process model. This model eliminates steps that were previously duplicated in IIS and ASP.NET, such as authentication. Additionally, Integrated mode enables the availability of managed features to all content types.

Classic application pool mode

When an application pool is in Classic mode, IIS 7.0 handles requests as in IIS 6.0 worker process isolation mode. ASP.NET requests first go through native processing steps in IIS and are then routed to Aspnet_isapi.dll for processing of managed code in the managed runtime. Finally, the request is routed back through IIS to send the response.

This separation of the IIS and ASP.NET request-processing models results in duplication of some processing steps, such as authentication and authorization. Additionally, managed code features, such as forms authentication, are only available to ASP.NET applications or applications for which you have script mapped all requests to be handled by aspnet_isapi.dll.

Be sure to test your existing applications for compatibility in Integrated mode before upgrading a production environment to IIS 7.0 and assigning applications to application pools in Integrated mode. You should only add an application to an application pool in Classic mode if the application fails to work in Integrated mode. For example, your application might rely on an authentication token passed from IIS to the managed runtime, and, due to the new architecture in IIS 7.0, the process breaks your application.

Taken from: What is the difference between DefaultAppPool and Classic .NET AppPool in IIS7?

You can use the set() function to convert an iterable into a set, and then use standard set update operator (|=) to add the unique values from your new set into the existing one.

>>> a = { 1, 2, 3 }
>>> b = ( 3, 4, 5 )
>>> a |= set(b)
>>> a
set([1, 2, 3, 4, 5])

When divided by zero

1. If you divide double by 0, JVM will show Infinity.

   public static void main(String [] args){ double a=10.00; System.out.println(a/0); }
   

   Console: Infinity

2. If you divide int by 0, then JVM will throw Arithmetic Exception.

   public static void main(String [] args){
       int a=10;
       System.out.println(a/0);
   }
   

   Console: Exception in thread "main" java.lang.ArithmeticException: / by zero

Heh, I just taught this class.

There are several options.
Simple: Pick the first or last element of the range. (bad on partially sorted input) Better: Pick the item in the middle of the range. (better on partially sorted input)

However, picking any arbitrary element runs the risk of poorly partitioning the array of size n into two arrays of size 1 and n-1. If you do that often enough, your quicksort runs the risk of becoming O(n^2).

One improvement I've seen is pick median(first, last, mid); In the worst case, it can still go to O(n^2), but probabilistically, this is a rare case.

For most data, picking the first or last is sufficient. But, if you find that you're running into worst case scenarios often (partially sorted input), the first option would be to pick the central value( Which is a statistically good pivot for partially sorted data).

If you're still running into problems, then go the median route.

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

I've done it with two annotations for test class: @RunWith(SpringRunner.class) and @SpringBootTest. Example:

@RunWith(SpringRunner.class )
@SpringBootTest
public class ProtocolTransactionServiceTest {

    @Autowired
    private ProtocolTransactionService protocolTransactionService;
}

@SpringBootTest loads the whole context, which was OK in my case.

Rand() does generate a uniform distribution of random numbers between 0 and 1, but the norminv (or norm.inv) function is taking the uniform distributed Rand() as an input to generate the normally distributed sample set.

I wasn't able to use Model::truncate() as it would error:

SQLSTATE[42000]: Syntax error or access violation: 1701 Cannot truncate a table referenced in a foreign key constraint

And unfortunately Model::delete() doesn't work (at least in Laravel 5.0):

Non-static method Illuminate\Database\Eloquent\Model::delete() should not be called statically, assuming $this from incompatible context

But this does work:

(new Model)->newQuery()->delete()

That will soft-delete all rows, if you have soft-delete set up. To fully delete all rows including soft-deleted ones you can change to this:

(new Model)->newQueryWithoutScopes()->forceDelete()

Change the content type to 'application/x-www-form-urlencoded'

    public static void Serialize(string path, T type)
    {
        var serializer = new XmlSerializer(type.GetType());
        using (var writer = new FileStream(path, FileMode.Create))
        {
            serializer.Serialize(writer, type);
        }
    }

    public static T DeSerialize(string path)
    {
        T type;
        var serializer = new XmlSerializer(typeof(T));
        using (var reader = XmlReader.Create(path))
        {
            type = serializer.Deserialize(reader) as T;
        }
        return type;
    }
}

Seems like this question is kind of duplicate with another one, where I've collect some marshal/unmarshal solutions into one post. You may check it here: Dynamic tag names with JAXB.

In short:

1. A container class for @xmlAnyElement should be created
2. An XmlAdapter can be used in pair with @XmlJavaTypeAdapter to convert between the container class and Map<>;

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2:Win32_Process")
objWMIService.Create "notepad.exe", null, null, intProcessID
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colMonitoredProcesses = objWMIService.ExecNotificationQuery _
    ("Select * From __InstanceDeletionEvent Within 1 Where TargetInstance ISA 'Win32_Process'")
Do Until i = 1
    Set objLatestProcess = colMonitoredProcesses.NextEvent
    If objLatestProcess.TargetInstance.ProcessID = intProcessID Then
        i = 1
    End If
Loop
Wscript.Echo "Notepad has been terminated."

The easiest way I found to set Facebook Open Graph to every Joomla article, was to place in com_content/article/default.php override, next code:

$app    = JFactory::getApplication();
$path   = JURI::root();

$document = JFactory::getDocument();
$document->addCustomTag('<meta property="og:title" content="YOUR SITE TITLE" />');
$document->addCustomTag('<meta property="og:name" content="YOUR SITE NAME" />');
$document->addCustomTag('<meta property="og:description" content="YOUR SITE DESCRIPTION" />');
$document->addCustomTag('<meta property="og:site_name" content="YOUR SITE NAME" />');
if (isset($images->image_fulltext) and !empty($images->image_fulltext)) : 
    $document->addCustomTag('<meta property="og:image" content="'.$path.'<?php echo htmlspecialchars($images->image_fulltext); ?>" />');
else :
    $document->addCustomTag('<meta property="og:image" content="'.$path.'images/logo.png" />');
 endif;

This will place meta og tags in the head with details from current article.

IF they are both UTC date-time values you can do TimeSpan diff = dateTime1 - dateTime2;

Otherwise your chance of getting the correct answer in every single possible case is zero.

Just try this in razor

@{
    var selectList = new SelectList(
        new List<SelectListItem>
        {
            new SelectListItem {Text = "Google", Value = "Google"},
            new SelectListItem {Text = "Other", Value = "Other"},
        }, "Value", "Text");
}

and then

@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })

or

@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })

Use printf command to have 0 padding:

printf "%02d\n" $num

Your for loop will be like this:

for (( num=1; num<=5; num++ )); do printf "%02d\n" $num; done
01
02
03
04
05

There's the trusty strip_tags function. It's not pretty though. It'll only sanitize. You could combine it with a string replace to get your fancy underscores.

<?php
// to strip all tags and wrap italics with underscore
strip_tags(str_replace(array("<i>", "</i>"), array("_", "_"), $text));

// to preserve anchors...
str_replace("|a", "<a", strip_tags(str_replace("<a", "|a", $text)));

?>

WE had this problem on one machine and not another...the solution is to look in control panel at the VERSION of the Access Database Engine 2007 component. If it is version 12.0.45, you need to run the service pack 3 http://www.microsoft.com/en-us/download/confirmation.aspx?id=27835

The above link will install version 12.0.66...and this fixes the problem...thought I would post it since I haven't seen this solution on any other forum.

I just realized that the hist documentation is explicit about what to do when you already have an np.histogram

counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)

The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore

in your css :

 #txtComputer {
      font-size: 24px;
 }

You can style an input entirely (background, color, etc.) and even use the hover event.

Update: As Roko C.Bulijan pointed out.. you need to use .insertAfter to insert it after the selected div. Also see updated code if you want it appended to the end instead of beginning when cloned multiple times. DEMO

Code:

   var cloneCount = 1;;
   $("button").click(function(){
      $('#id')
          .clone()
          .attr('id', 'id'+ cloneCount++)
          .insertAfter('[id^=id]:last') 
           //            ^-- Use '#id' if you want to insert the cloned 
           //                element in the beginning
          .text('Cloned ' + (cloneCount-1)); //<--For DEMO
   }); 

Try,

$("#id").clone().attr('id', 'id1').after("#id");

If you want a automatic counter, then see below,

   var cloneCount = 1;
   $("button").click(function(){
      $("#id").clone().attr('id', 'id'+ cloneCount++).insertAfter("#id");
   }); 

It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:

[bits 32]
.
.
and  [ebp-4], 0

When you get in this state, try performing a Rebuild-All. If this fixes the problem, you may have the same issue I had.

Some background (my understanding):

• SQLite has 1 managed assembly (System.Data.SQLite.dll) and several platform specific assemblies (SQLite.Interop.dll). When installing SQLite with Nuget, Nuget will add the platform specific assemblies to your project (within several folders: \x86, \x64), and configures these dlls to "Copy Always".

• Upon load, the managed assembly will search for platform specific assemblies inside the \x86 and \x64 folders. You can see more on that here. The exception is this managed assembly attempting to find the relevant (SQLite.Interop.dll) inside these folders (and failing).

My Scenario:

I have 2 projects in my solution; a WPF app, and a class library. The WPF app references the class library, and the class library references SQLite (installed via Nuget).

The issue for me was when I modify only the WPF app, VS attempts to do a partial rebuild (realizing that the dependent dll hasn't changed). Somewhere in this process, VS cleans the content of the \x86 and \x64 folders (blowing away SQLite.Interop.dll). When I do a full Rebuild-All, VS copies the folders and their contents correctly.

My Solution:

To fix this, I ended up adding a Post-Build process using xcopy to force copying the \x86 and \x64 folders from the class library to my WPF project \bin directory.

Alternatively, you could do fancier things with the build configuration / output directories.

It's very simple. Right click inside the internal browser and click "refresh".

strToLower should return a char * instead of a char. Something like this would do.

char *strToLower(char *cString)

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

Write with a javascript function

document.getElementById("myTable").insertRow(-1).innerHTML = '<tr>...</tr><tr>...</tr>';

For Single column sorting disable try this example :

<script type="text/javascript">                         
    $(document).ready(function() 
    {
        $("#example").dataTable({
           "aoColumnDefs": [
              { 'bSortable': false, 'aTargets': [ 0 ] }
           ]
        });
    });                                         
</script>

For Multiple columns try this example: you just need to add column number. By default it's starting from 0

<script type="text/javascript">                         
    $(document).ready(function() 
    {
        $("#example").dataTable({
           "aoColumnDefs": [
              { 'bSortable': false, 'aTargets': [ 0,1,2,4,5,6] }
           ]
        });
    });                                         
</script>  

Here only Column 3 works

Given the R data.frame:

> df1
  a b c
1 1 1 0
2 1 0 0
3 0 1 0
4 0 0 0

Shuffle row-wise:

> df2 <- df1[sample(nrow(df1)),]
> df2
  a b c
3 0 1 0
4 0 0 0
2 1 0 0
1 1 1 0

By default sample() randomly reorders the elements passed as the first argument. This means that the default size is the size of the passed array. Passing parameter replace=FALSE (the default) to sample(...) ensures that sampling is done without replacement which accomplishes a row wise shuffle.

Shuffle column-wise:

> df3 <- df1[,sample(ncol(df1))]
> df3
  c a b
1 0 1 1
2 0 1 0
3 0 0 1
4 0 0 0

but on the other hand it creates a completely useless list of integers just to loop over them. Isn't it a waste of memory, especially as far as big numbers of iterations are concerned?

That is what xrange(n) is for. It avoids creating a list of numbers, and instead just provides an iterator object.

In Python 3, xrange() was renamed to range() - if you want a list, you have to specifically request it via list(range(n)).

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

In my case I was using jackson-databind-2.8.8.jar that is not compatible with JDK 1.6 I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.

**Filter by name, age ** also, you can use the map function

difference between map and filter

1. map - The map() method creates a new array with the results of calling a function for every array element. The map method allows items in an array to be manipulated to the user’s preference, returning the conclusion of the chosen manipulation in an entirely new array. For example, consider the following array:

2. filter - The filter() method creates an array filled with all array elements that pass a test implemented by the provided function. The filter method is well suited for particular instances where the user must identify certain items in an array that share a common characteristic. For example, consider the following array:

const users = [
    { name: "john", age: 23 },
    { name: "john", age:43 },
    { name: "jim", age: 101 },
    { name: "bob", age: 67 }
];

const user = _.filter(users, {name: 'jim', age: 101});
console.log(user);

Or you could do:

var myDouble = Double((mySwiftString.text as NSString).doubleValue)

Redirecting stdout to a file might also be useful for this purpose:

from contextlib import redirect_stdout
with open('test.txt', 'w') as f:
  with redirect_stdout(f):
     for i in range(mylst.size):
        print(mylst[i])

get matched string back or false

function preg_match (regex, str) {
  if (new RegExp(regex).test(str)){
    return regex.exec(str);
  }
  return false;
}

Simplest ever solution for TextBox Validation in VB.NET

First, add new VB code file in your project.

1. Go To Solution Explorer
2. Right Click to your project
3. Select Add > New item...
4. Add new VB code file (i.e. example.vb)

or press Ctrl+Shift+A

COPY & PASTE following code into this file and give it a suitable name. (i.e. KeyValidation.vb)

Imports System.Text.RegularExpressions
Module Module1
    Public Enum ValidationType
        Only_Numbers = 1
        Only_Characters = 2
        Not_Null = 3
        Only_Email = 4
        Phone_Number = 5
    End Enum
    Public Sub AssignValidation(ByRef CTRL As Windows.Forms.TextBox, ByVal Validation_Type As ValidationType)
        Dim txt As Windows.Forms.TextBox = CTRL
        Select Case Validation_Type
            Case ValidationType.Only_Numbers
                AddHandler txt.KeyPress, AddressOf number_Leave
            Case ValidationType.Only_Characters
                AddHandler txt.KeyPress, AddressOf OCHAR_Leave
            Case ValidationType.Not_Null
                AddHandler txt.Leave, AddressOf NotNull_Leave
            Case ValidationType.Only_Email
                AddHandler txt.Leave, AddressOf Email_Leave
            Case ValidationType.Phone_Number
                AddHandler txt.KeyPress, AddressOf Phonenumber_Leave
        End Select
    End Sub
    Public Sub number_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        Dim numbers As Windows.Forms.TextBox = sender
        If InStr("1234567890.", e.KeyChar) = 0 And Asc(e.KeyChar) <> 8 Or (e.KeyChar = "." And InStr(numbers.Text, ".") > 0) Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub Phonenumber_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        Dim numbers As Windows.Forms.TextBox = sender
        If InStr("1234567890.()-+ ", e.KeyChar) = 0 And Asc(e.KeyChar) <> 8 Or (e.KeyChar = "." And InStr(numbers.Text, ".") > 0) Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub OCHAR_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        If InStr("1234567890!@#$%^&*()_+=-", e.KeyChar) > 0 Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub NotNull_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim No As Windows.Forms.TextBox = sender
        If No.Text.Trim = "" Then
            MsgBox("This field Must be filled!")
            No.Focus()
        End If
    End Sub
    Public Sub Email_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim Email As Windows.Forms.TextBox = sender
        If Email.Text <> "" Then
            Dim rex As Match = Regex.Match(Trim(Email.Text), "^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,3})$", RegexOptions.IgnoreCase)
            If rex.Success = False Then
                MessageBox.Show("Please Enter a valid Email Address", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information)
                Email.BackColor = Color.Red
                Email.Focus()
                Exit Sub
            Else
                Email.BackColor = Color.White
            End If
        End If
    End Sub
End Module

Now use following code to Form Load Event like below.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        AssignValidation(Me.TextBox1, ValidationType.Only_Digits)
        AssignValidation(Me.TextBox2, ValidationType.Only_Characters)
        AssignValidation(Me.TextBox3, ValidationType.No_Blank)
        AssignValidation(Me.TextBox4, ValidationType.Only_Email)
End Sub

Done..!

In C# it doesn't matter. The two code samples you give are utterly equivalent. In the first example the C# compiler (or is it the CLR?) will construct an empty constructor and initialise the variables as if they were in the constructor (there's a slight nuance to this that Jon Skeet explains in the comments below). If there is already a constructor then any initialisation "above" will be moved into the top of it.

In terms of best practice the former is less error prone than the latter as someone could easily add another constructor and forget to chain it.

example how i made it , After i fill a Maximum length it will blur from my Field (and the Keyboard will disappear ) , if you have more than one field , you can just add the line that i add '//'

var MaxLength = 8;
    $(document).ready(function () {
        $('#MyTB').keyup(function () {
            if ($(this).val().length >= MaxLength) {
               $('#MyTB').blur();
             //  $('#MyTB2').focus();
         }
          }); });

This happens when libraries added to the project doesn't have the correct path.

1. Right click on your project (from package explorer)
2. Got build path -> configure build path
3. Select the libraries tab
4. Fix the path error (give the correct path) by editing jars or classes at fault

To continue using the iframe YouTube, you should only have to change ?autoplay=1 to ?autoplay=0.

Another way to accomplish this would be by using the YouTube JavaScript Player API. (https://developers.google.com/youtube/js_api_reference)

Edit: the YouTube JavaScript Player API is no longer supported.

<div id="howToVideo"></div>

<script type="application/javascript">

    var ga = document.createElement('script');
    ga.type = 'text/javascript';
    ga.async = false;
    ga.src = 'http://www.youtube.com/player_api';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(ga, s);

    var done = false;
    var player;

    function onYouTubePlayerAPIReady() {
        player = new YT.Player('howToVideo', {
            height: '390',
            width: '640',
            videoId: 'qUJYqhKZrwA',
        playerVars: {
            controls: 0,
            disablekb: 1
        },
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
    }
    function onPlayerReady(evt) {
        console.log('onPlayerReady', evt);
    }
    function onPlayerStateChange(evt) {
        console.log('onPlayerStateChange', evt);
        if (evt.data == YT.PlayerState.PLAYING && !done) {
            setTimeout(stopVideo, 6000);
            done = true;
        }
    }

    function stopVideo() {
        console.log('stopVideo');
        player.stopVideo();
    }

</script>

Here is a jsfiddle for the example: http://jsfiddle.net/fgkrj/

Note that player controls are disabled in the "playerVars" part of the player. The one sacrifice you make is that users are still able to pause the video by clicking on it. I would suggest writing a simple javascript function that subscribes to a stop event and calls player.playVideo().

Or use JodaTime:

DateTime lastWeek = new DateTime().minusDays(7);

Advanced Conventional Formatting [Update]

XMLSpectrum is an open source syntax-highlighter. Supporting XML - but with special features for XSLT 2.0, XSD 1.1 and XPath 2.0. I'm mentioning this here because it also has special formatting capabilities for XML: it vertically aligns attributes and their contents as well as elements - to enhance XML readability.

The output HTML is suitable for reviewing in a browser or if the XML needs further editing it can be copied and pasted into an XML editor of your choice

Because xmlspectrum.xsl uses its own XML text parser, all content such as entity references and CDATA sections are preserved - as in an editor.

Note on usage: this is just an XSLT 2.0 stylesheet so you would need to enclose the required command-line (samples provided) in a small script so you could automatically transform the XML source.

Virtual Formatting

XMLQuire is a free XML editor that has special formatting capabilities - it formats XML properly, including multi-line attributes, attribute-values, word-wrap indentation and even XML comments.

All XML indentation is done without inserting tabs or spaces, ensuring the integrity of the XML is maintained. For versions of Windows later than XP, no installation is needed, its just a 3MB .exe file.

If you need to print out the formatted XML there are special options within the print-preview, such as line-numbering that follows the indentation. If you need to copy the formatted XML to a word processor as rich text, that's available too.

[Disclosure: I maintain both XMLQuire and XMLSpectrum as 'home projects']

Buttons can be added to frozen rows as images. Assigning a function within the attached script to the button makes it possible to run the function. The comment which says you can not is of course a very old comment, possibly things have changed now.

For those wondering why ipairs doesn't print all the values of the table all the time, here's why (I would comment this, but I don't have enough good boy points).

The function ipairs only works on tables which have an element with the key 1. If there is an element with the key 1, ipairs will try to go as far as it can in a sequential order, 1 -> 2 -> 3 -> 4 etc until it cant find an element with a key that is the next in the sequence. The order of the elements does not matter.

Tables that do not meet those requirements will not work with ipairs, use pairs instead.

Examples:

ipairsCompatable = {"AAA", "BBB", "CCC"}
ipairsCompatable2 = {[1] = "DDD", [2] = "EEE", [3] = "FFF"}
ipairsCompatable3 = {[3] = "work", [2] = "does", [1] = "this"}

notIpairsCompatable = {[2] = "this", [3] = "does", [4] = "not"}
notIpairsCompatable2 = {[2] = "this", [5] = "doesn't", [24] = "either"}

ipairs will go as far as it can with it's iterations but won't iterate over any other element in the table.

kindofIpairsCompatable = {[2] = 2, ["cool"] = "bro", [1] = 1, [3] = 3, [5] = 5 }

When printing these tables, these are the outputs. I've also included pairs outputs for comparison.

ipairs + ipairsCompatable
1       AAA
2       BBB
3       CCC

ipairs + ipairsCompatable2
1       DDD
2       EEE
3       FFF

ipairs + ipairsCompatable3
1       this
2       does
3       work

ipairs + notIpairsCompatable

pairs + notIpairsCompatable
2       this
3       does
4       not

ipairs + notIpairsCompatable2

pairs + notIpairsCompatable2
2       this
5       doesnt
24      either

ipairs + kindofIpairsCompatable
1       1
2       2
3       3

pairs + kindofIpairsCompatable
1       1
2       2
3       3
5       5
cool    bro

Unlike SOAP, REST isn't a standardized protocol so it's a bit difficult to have a "REST Client". However, since most RESTful services use HTTP as their underlying protocol, you should be able to use any HTTP library. In addition to cURL, PHP has these via PEAR:

HTTP_Request2

which replaced

HTTP_Request

A sample of how they do HTTP Basic Auth

// This will set credentials for basic auth
$request = new HTTP_Request2('http://user:[email protected]/secret/');

The also support Digest Auth

// This will set credentials for Digest auth
$request->setAuth('user', 'password', HTTP_Request2::AUTH_DIGEST);

If compiling from source with --disable-all then DOMDocument support can be enabled with
--enable-dom

Example:

./configure --disable-all --enable-dom

JSON does not know anything about dates. What .NET does is a non-standard hack/extension.

I would use a format that can be easily converted to a Date object in JavaScript, i.e. one that can be passed to new Date(...). The easiest and probably most portable format is the timestamp containing milliseconds since 1970.

Ended up creating array specific methods to do this. Much like the encoding/binary package with specific methods for each int type. For example binary.BigEndian.PutUint16([]byte, uint16).

func byte16PutString(s string) [16]byte {
    var a [16]byte
    if len(s) > 16 {
        copy(a[:], s)
    } else {
        copy(a[16-len(s):], s)
    }
    return a
}

var b [16]byte
b = byte16PutString("abc")
fmt.Printf("%v\n", b)

Output:

[0 0 0 0 0 0 0 0 0 0 0 0 0 97 98 99]

Notice how I wanted padding on the left, not the right.

This is a duplicate answer **Reconnect to a driver in python selenium ** This is applicable on all drivers and for java api.

1. open a driver

driver = webdriver.Firefox()  #python

2. extract to session_id and _url from driver object.

url = driver.command_executor._url       #"http://127.0.0.1:60622/hub"
session_id = driver.session_id            #'4e167f26-dc1d-4f51-a207-f761eaf73c31'

3. Use these two parameter to connect to your driver.

driver = webdriver.Remote(command_executor=url,desired_capabilities={})
driver.close()   # this prevents the dummy browser
driver.session_id = session_id

And you are connected to your driver again.

driver.get("http://www.mrsmart.in")

With the latest version of Xcode (3.2.2), you can drag and drop any crash reports into the Device Logs section of the Xcode Organiser and they will automatically by symbolicated for you. I think this works best if you built that version of the App using Build & Archive (also part of Xcode 3.2.2)

The -s option of read is not defined in the POSIX standard. See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html. I wanted something that would work for any POSIX shell, so I wrote a little function that uses stty to disable echo.

#!/bin/sh

# Read secret string
read_secret()
{
    # Disable echo.
    stty -echo

    # Set up trap to ensure echo is enabled before exiting if the script
    # is terminated while echo is disabled.
    trap 'stty echo' EXIT

    # Read secret.
    read "$@"

    # Enable echo.
    stty echo
    trap - EXIT

    # Print a newline because the newline entered by the user after
    # entering the passcode is not echoed. This ensures that the
    # next line of output begins at a new line.
    echo
}

This function behaves quite similar to the read command. Here is a simple usage of read followed by similar usage of read_secret. The input to read_secret appears empty because it was not echoed to the terminal.

[susam@cube ~]$ read a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c

Here is another that uses the -r option to preserve the backslashes in the input. This works because the read_secret function defined above passes all arguments it receives to the read command.

[susam@cube ~]$ read -r a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret -r a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c

Finally, here is an example that shows how to use the read_secret function to read a password in a POSIX compliant manner.

printf "Password: "
read_secret password
# Do something with $password here ...

Sorry I know this is old but why not style all tr elements the way you want all except the first and the use the psuedo class :first-child where you revoke what you specified for all tr elements.

ubar jar is also known as fat jar i.e. jar with dependencies.
There are three common methods for constructing an uber jar:

1. Unshaded: Unpack all JAR files, then repack them into a single JAR. Works with Java's default class loader. Tools maven-assembly-plugin
2. Shaded: Same as unshaded, but rename (i.e., "shade") all packages of all dependencies. Works with Java's default class loader. Avoids some (not all) dependency version clashes. Tools maven-shade-plugin
3. JAR of JARs: The final JAR file contains the other JAR files embedded within. Avoids dependency version clashes. All resource files are preserved. Tools: Eclipse JAR File Exporter

I don't know of Google voice, but using the javaScript speech SpeechSynthesisUtterance, you can add a click event to the element you are reference to. eg:

const listenBtn = document.getElementById('myvoice');

listenBtn.addEventListener('click', (e) => {
  e.preventDefault();

  const msg = new SpeechSynthesisUtterance(
    "Hello, hope my code is helpful"
  );
  window.speechSynthesis.speak(msg);

});

<button type="button" id='myvoice'>Listen to me</button>

If you are still finding that the default wrong Java version (1.7) is being used instead of your Java home directory, then all you need to do is simply change the order of your PATH variable to set JAVA_HOME\bin before your Windows directory in your PATH variable, save it and restart cygwin. Test it out to make sure everything will work fine. It should not have any adverse effect because you want your own Java version to override the default which comes with Windows. Good luck!

Most answers are using iloc which is good for selection by position.

If you need selection-by-label loc would be more convenient.

For getting a value explicitly (equiv to deprecated df.get_value('a','A'))

# this is also equivalent to df1.at['a','A']
In [55]: df1.loc['a', 'A'] 
Out[55]: 0.13200317033032932

While on the upper line in normal mode, hit Shift+j.

You can prepend a count too, so 3J on the top line would join all those lines together.

I'm the maintainer of Mongoose. findById() is a built-in method on Mongoose models. findById(id) is equivalent to findOne({ _id: id }), with one caveat: findById() with 0 params is equivalent to findOne({ _id: null }).

You can read more about findById() on the Mongoose docs and this findById() tutorial.

For Xcode 7, you have a much simpler solution. The only extra work is that you have to create a configuration plist file for exporting archive.

(Compared to Xcode 6, in the results of xcrun xcodebuild -help, -exportFormat and -exportProvisioningProfile options are not mentioned any more; the former is deleted, and the latter is superseded by -exportOptionsPlist.)

Step 1, change directory to the folder including .xcodeproject or .xcworkspace file.

cd MyProjectFolder

Step 2, use Xcode or /usr/libexec/PlistBuddy exportOptions.plist to create export options plist file. By the way, xcrun xcodebuild -help will tell you what keys you have to insert to the plist file.

Step 3, create .xcarchive file (folder, in fact) as follows(build/ directory will be automatically created by Xcode right now),

xcrun xcodebuild -scheme MyApp -configuration Release archive -archivePath build/MyApp.xcarchive

Step 4, export as .ipa file like this, which differs from Xcode6

xcrun xcodebuild -exportArchive -exportPath build/ -archivePath build/MyApp.xcarchive/ -exportOptionsPlist exportOptions.plist

Now, you get an ipa file in build/ directory. Just send it to apple App Store.

By the way, the ipa file created by Xcode 7 is much larger than by Xcode 6.

it "should call 'bar' with appropriate arguments" do
  expect(subject).to receive(:bar).with("an argument I want")

Real nested classes with public/protected/private accessibility were proposed in 2013 for PHP 5.6 as an RFC but did not make it (No voting yet, no update since 2013 - as of 2021/02/03):

https://wiki.php.net/rfc/nested_classes

class foo {
    public class bar {
 
    }
}

At least, anonymous classes made it into PHP 7

https://wiki.php.net/rfc/anonymous_classes

From this RFC page:

Future Scope

The changes made by this patch mean named nested classes are easier to implement (by a tiny bit).

So, we might get nested classes in some future version, but it's not decided yet.

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

JavaScript's forEach works a bit different from how one might be used to from other languages for each loops. If reading on the MDN, it says that a function is executed for each of the elements in the array, in ascending order. To continue to the next element, that is, run the next function, you can simply return the current function without having it do any computation.

Adding a return and it will go to the next run of the loop:

var myArr = [1,2,3,4];_x000D_
_x000D_
myArr.forEach(function(elem){_x000D_
  if (elem === 3) {_x000D_
    return;_x000D_
  }_x000D_
_x000D_
  console.log(elem);_x000D_
});

Output: 1, 2, 4

In Bash (and ksh, zsh, dash, etc.), you can use parameter expansion with % which will remove characters from the end of the string or # which will remove characters from the beginning of the string. If you use a single one of those characters, the smallest matching string will be removed. If you double the character, the longest will be removed.

$ a='hello:world'

$ b=${a%:*}
$ echo "$b"
hello

$ a='hello:world:of:tomorrow'

$ echo "${a%:*}"
hello:world:of

$ echo "${a%%:*}"
hello

$ echo "${a#*:}"
world:of:tomorrow

$ echo "${a##*:}"
tomorrow

A functor is pretty much just a class which defines the operator(). That lets you create objects which "look like" a function:

// this is a functor
struct add_x {
  add_x(int val) : x(val) {}  // Constructor
  int operator()(int y) const { return x + y; }

private:
  int x;
};

// Now you can use it like this:
add_x add42(42); // create an instance of the functor class
int i = add42(8); // and "call" it
assert(i == 50); // and it added 42 to its argument

std::vector<int> in; // assume this contains a bunch of values)
std::vector<int> out(in.size());
// Pass a functor to std::transform, which calls the functor on every element 
// in the input sequence, and stores the result to the output sequence
std::transform(in.begin(), in.end(), out.begin(), add_x(1)); 
assert(out[i] == in[i] + 1); // for all i

There are a couple of nice things about functors. One is that unlike regular functions, they can contain state. The above example creates a function which adds 42 to whatever you give it. But that value 42 is not hardcoded, it was specified as a constructor argument when we created our functor instance. I could create another adder, which added 27, just by calling the constructor with a different value. This makes them nicely customizable.

As the last lines show, you often pass functors as arguments to other functions such as std::transform or the other standard library algorithms. You could do the same with a regular function pointer except, as I said above, functors can be "customized" because they contain state, making them more flexible (If I wanted to use a function pointer, I'd have to write a function which added exactly 1 to its argument. The functor is general, and adds whatever you initialized it with), and they are also potentially more efficient. In the above example, the compiler knows exactly which function std::transform should call. It should call add_x::operator(). That means it can inline that function call. And that makes it just as efficient as if I had manually called the function on each value of the vector.

If I had passed a function pointer instead, the compiler couldn't immediately see which function it points to, so unless it performs some fairly complex global optimizations, it'd have to dereference the pointer at runtime, and then make the call.

I wrote rather good function that can generate vertical and horizontal tables:

function generateTable(rowsData, titles, type, _class) {
    var $table = $("<table>").addClass(_class);
    var $tbody = $("<tbody>").appendTo($table);


    if (type == 2) {//vertical table
        if (rowsData.length !== titles.length) {
            console.error('rows and data rows count doesent match');
            return false;
        }
        titles.forEach(function (title, index) {
            var $tr = $("<tr>");
            $("<th>").html(title).appendTo($tr);
            var rows = rowsData[index];
            rows.forEach(function (html) {
                $("<td>").html(html).appendTo($tr);
            });
            $tr.appendTo($tbody);
        });

    } else if (type == 1) {//horsantal table 
        var valid = true;
        rowsData.forEach(function (row) {
            if (!row) {
                valid = false;
                return;
            }

            if (row.length !== titles.length) {
                valid = false;
                return;
            }
        });

        if (!valid) {
            console.error('rows and data rows count doesent match');
            return false;
        }

        var $tr = $("<tr>");
        titles.forEach(function (title, index) {
            $("<th>").html(title).appendTo($tr);
        });
        $tr.appendTo($tbody);

        rowsData.forEach(function (row, index) {
            var $tr = $("<tr>");
            row.forEach(function (html) {
                $("<td>").html(html).appendTo($tr);
            });
            $tr.appendTo($tbody);
        });
    }

    return $table;
}

usage example:

var title = [
    '????? ?????',
    '????? ?????????',
    '????? ?? ???'
];

var rows = [
    [number_format(data.source.area,2)],
    [number_format(data.intersection.area,2)],
    [number_format(data.deference.area,2)]
];

var $ft = generateTable(rows, title, 2,"table table-striped table-hover table-bordered");

$ft.appendTo( GroupAnalyse.$results );

var title = [
    '???',
    '?????? ????',
    '?????? ????',
    '?????',
    '????? ??? ?????',
];

var rows = data.edgesData.map(function (r) {
    return [
        r.directionText,
        r.lineLength,
        r.newLineLength,
        r.stateText,
        r.lineLengthDifference
    ];
});


var $et = generateTable(rows, title, 1,"table table-striped table-hover table-bordered");

$et.appendTo( GroupAnalyse.$results );

$('<hr/>').appendTo( GroupAnalyse.$results );

example result:

Since jQuery 3.3.0, it is possible to pass arrays to .addClass(), .removeClass() and toggleClass(), which makes it easier if there is any logic which determines which classes should be added or removed, as you don't need to mess around with the space-delimited strings.

$("div").removeClass(["class1", "class2"]); 

My ajax never gets fired until I wrapped the whole thing in

setTimeout(function(){ .... }, 3000);

I was using it in mounted section of Vue. it needs more time.

If you're using Spring 3.1 or greater (yikes, was hoping that support went back further), you can use the UriComponents and UriComponentsBuilder:

UriComponents components = UriComponentsBuilder.fromUri(uri).build();
List<String> myParam = components.getQueryParams().get("myParam");

components.getQueryParams() returns a MultiValueMap<String, String>

Here's some more documentation.

None of the solutions work if you are using Jenkins build!! When pom is run inside Jenkins build server.. these solutions will fail, as Jenkins run pom will try to download these files from enterprise repository.

Copy jars under src/main/resources/lib (create lib folder). These will be part of your project and go all the way to deployment server. In deployment server, make sure your startup scripts contain src/main/resources/lib/* in classpath. Viola.

It is 2019, and here is what is working - despite advice here and there, what I found on the internet halfway documented is using setuptools_scm, passed as options to setuptools.setup. This will include any data files that are versioned on your VCS, be it git or any other, to the wheel package, and will make "pip install" from the git repository to bring those files along.

So, I just added these two lines to the setup call on "setup.py". No extra installs or import required:

    setup_requires=['setuptools_scm'],
    include_package_data=True,

No need to manually list package_data, or in a MANIFEST.in file - if it is versioned, it is included in the package. The docs on "setuptools_scm" put emphasis on creating a version number from the commit position, and disregard the really important part of adding the data files. (I can't care less if my intermediate wheel file is named "*0.2.2.dev45+g3495a1f" or will use the hardcoded version number "0.3.0dev0" I've typed in - but leaving crucial files for the program to work behind is somewhat important)

I don't see the need for Indirect, especially for conditional formatting.

The simplest way to self-reference a cell, row or column is to refer to it normally, e.g., "=A1" in cell A1, and make the reference partly or completely relative. For example, in a conditional formatting formula for checking whether there's a value in the first column of various cells' rows, enter the following with A1 highlighted and copy as necessary. The conditional formatting will always refer to column A for the row of each cell:

= $A1 <> ""

You're getting None because list.sort() it operates in-place, meaning that it doesn't return anything, but modifies the list itself. You only need to call a.sort() without assigning it to a again.

There is a built in function sorted(), which returns a sorted version of the list - a = sorted(a) will do what you want as well.

Only when you multiply integer with a string, you will get repetitive string..

You can use int() factory method to create integer out of string form of integer..

>>> int('1') * int('9')
9
>>> 
>>> '1' * 9
'111111111'
>>>
>>> 1 * 9
9
>>> 
>>> 1 * '9'
'9'

• If both operand is int, you will get multiplication of them as int.
• If first operand is string, and second is int.. Your string will be repeated that many times, as the value in your integer 2nd operand.
• If first operand is integer, and second is string, then you will get multiplication of both numbers in string form..

The accepted answer to how to replace multiple strings together in Oracle suggests using nested REPLACE statements, and I don't think there is a better way.

If you are going to make heavy use of this, you could consider writing your own function:

CREATE TYPE t_text IS TABLE OF VARCHAR2(256);

CREATE FUNCTION multiple_replace(
  in_text IN VARCHAR2, in_old IN t_text, in_new IN t_text
)
  RETURN VARCHAR2
AS
  v_result VARCHAR2(32767);
BEGIN
  IF( in_old.COUNT <> in_new.COUNT ) THEN
    RETURN in_text;
  END IF;
  v_result := in_text;
  FOR i IN 1 .. in_old.COUNT LOOP
    v_result := REPLACE( v_result, in_old(i), in_new(i) );
  END LOOP;
  RETURN v_result;
END;

and then use it like this:

SELECT multiple_replace( 'This is #VAL1# with some #VAL2# to #VAL3#',
                         NEW t_text( '#VAL1#', '#VAL2#', '#VAL3#' ),
                         NEW t_text( 'text', 'tokens', 'replace' )
                       )
FROM dual

This is text with some tokens to replace

If all of your tokens have the same format ('#VAL' || i || '#'), you could omit parameter in_old and use your loop-counter instead.

There are available Extension methods to parse them into other primitive types.

• "10".toInt()
• "10".toLong()
• "true".toBoolean()
• "10.0".toFloat()
• "10.0".toDouble()
• "10".toByte()
• "10".toShort()

String num = "10";
Integer.parseInt(num );

I was debugging a menu hover state with Chrome and did this to be able to see the hover state code:

In the Elements panel click over Toggle Element state button and select :hover.

In the Scripts panel go to Event Listeners Breakpoints in the right bottom section and select Mouse -> mouseup.

Now inspect the Menu and select the box you want. When you release the mouse button it should stop and show you the selected element hover state in the Elements panel (look at the Styles section).

I strongly recommend this video, in order to pick the proper tool at the moment to debug our code.

https://www.youtube.com/watch?v=GwgF8GcynV0

Personally, I'd highlight two big topics in this video.

• Pry is awesome for debug data, "pry is a data explorer" (sic)
• Debugger seems to be better to debug step by step.

That's my two cents!

<script type="text/javascript">
        function returnwasset(){
            alert('return sent');
            $.ajax({
                type: "POST",
                url: "process.php",
                data: somedata;
                dataType:'text'; //or HTML, JSON, etc.
                success: function(response){
                    alert(response);
                    //echo what the server sent back...
                }
            });
        }
    </script>

You shouldn't use ForEach in that way. Read Lippert's “foreach” vs “ForEach”

If you want to be cruel with yourself (and the world), at least don't create useless List

employees.All(p => {
    collection.AddRange(p.Departments);
    p.Departments.All(u => { u.SomeProperty = null; return true; } );
    return true;
});

Note that the result of the All expression is a bool value that we are discarding (we are using it only because it "cycles" all the elements)

I'll repeat. You shouldn't use ForEach to change objects. LINQ should be used in a "functional" way (you can create new objects but you can't change old objects nor you can create side-effects). And what you are writing is creating so many useless List only to gain two lines of code...

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

Vartec's answer doesn't read all lines, so I made a version that did:

def run_command(command):
    p = subprocess.Popen(command,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.STDOUT)
    return iter(p.stdout.readline, b'')

Usage is the same as the accepted answer:

command = 'mysqladmin create test -uroot -pmysqladmin12'.split()
for line in run_command(command):
    print(line)

It's a horrible thing to do, as everybody else has said, but if you really are intent on doing it, use this code, and put a load of returns at the top of the page's source:

<html>
  <head>
    <script>
      function disableClick(){
        document.onclick=function(event){
          if (event.button == 2) {
            alert('Right Click Message');
            return false;
          }
        }
      }
    </script>
  </head>
  <body onLoad="disableClick()">
  </body>
</html>

By far the best tool I have used for reverse engineering, and round tripping java -> UML is Borland's Together. It is based on Eclipse (not just a single plugin) and really works well.

One way to get around this is to use implicit casting:

bool DoesEntityExist<T>(T entity, Guid guid, ITransaction transaction) where T : IGloballyIdentifiable;

calling it like so:

DoesEntityExist(entity, entityGuid, transaction);

Going a step further, you can turn it into an extension method (it will need to be declared in a static class):

static bool DoesEntityExist<T>(this T entity, Guid guid, ITransaction transaction) where T : IGloballyIdentifiable;

calling as so:

entity.DoesEntityExist(entityGuid, transaction);

You should use the $location service

Angular docs:

• Guide to using $location
• $location API

That number indicates Date and Time Styles

You need to look at CAST and CONVERT (Transact-SQL). Here you can find the meaning of all these Date and Time Styles.

Styles with century (e.g. 100, 101 etc) means year will come in yyyy format. While styles without century (e.g. 1,7,10) means year will come in yy format.

You can also refer to SQL Server Date Formats. Here you can find all date formats with examples.

There is no static Equals method in the Array class, so what you are using is actually Object.Equals, which determines if the two object references point to the same object.

If you want to check if the arrays contains the same items in the same order, you can use the SequenceEquals extension method:

childe1.SequenceEqual(grandFatherNode)

Edit:

To use SequenceEquals with multidimensional arrays, you can use an extension to enumerate them. Here is an extension to enumerate a two dimensional array:

public static IEnumerable<T> Flatten<T>(this T[,] items) {
  for (int i = 0; i < items.GetLength(0); i++)
    for (int j = 0; j < items.GetLength(1); j++)
      yield return items[i, j];
}

Usage:

childe1.Flatten().SequenceEqual(grandFatherNode.Flatten())

If your array has more dimensions than two, you would need an extension that supports that number of dimensions. If the number of dimensions varies, you would need a bit more complex code to loop a variable number of dimensions.

You would of course first make sure that the number of dimensions and the size of the dimensions of the arrays match, before comparing the contents of the arrays.

Edit 2:

Turns out that you can use the OfType<T> method to flatten an array, as RobertS pointed out. Naturally that only works if all the items can actually be cast to the same type, but that is usually the case if you can compare them anyway. Example:

childe1.OfType<Person>().SequenceEqual(grandFatherNode.OfType<Person>())

You are getting error for HttpClient so, you are missing HttpClientModule for that.

You should import it in app.module.ts file like this -

import { HttpClientModule } from '@angular/common/http';

and mention it in the NgModule Decorator like this -

@NgModule({
...
imports:[ HttpClientModule ]
...
})

If this even doesn't work try clearing cookies of the browser and try restarting your server. Hopefully it may work, I was getting the same error.

SQL> STARTUP FRORCE

You can also use,

parent.jQuery("#testdiv").attr("style", content from form);

Possible alternatives:

• Rename the table SystemUser
• Use brackets
• Keep the plural table names.

IMO using brackets is technically the safest approach, though it is a bit cumbersome. IMO it's 6 of one, half-a-dozen of the other, and your solution really just boils down to personal/team preference.
