Check here: http://www.allapplabs.com/java_design_patterns/abstract_factory_pattern.htm it seems that Factory method uses a particular class(not abstract) as a base class while Abstract factory uses an abstract class for this. Also if using an interface instead of abstract class the result will be a different implementation of Abstract Factory pattern.

:D

Consider this example for easy understanding.

What does telecommunication companies provide? Broadband, phone line and mobile for instance and you're asked to create an application to offer their products to their customers.

Generally what you'd do here is, creating the products i.e broadband, phone line and mobile are through your Factory Method where you know what properties you have for those products and it's pretty straightforward.

Now, the company wants to offer their customer a bundle of their products i.e broadband, phone line, and mobile altogether, and here comes the Abstract Factory to play.

Abstract Factory is, in other words, are the composition of other factories who are responsible for creating their own products and Abstract Factory knows how to place these products in more meaningful in respect of its own responsibilities.

In this case, the BundleFactory is the Abstract Factory, BroadbandFactory, PhonelineFactory and MobileFactory are the Factory. To simplify more, these Factories will have Factory Method to initialise the individual products.

Se the code sample below:

public class BroadbandFactory : IFactory {
    public static Broadband CreateStandardInstance() {
        // broadband product creation logic goes here
    }
}

public class PhonelineFactory : IFactory {
    public static Phoneline CreateStandardInstance() {
        // phoneline product creation logic goes here
    }
}

public class MobileFactory : IFactory {
    public static Mobile CreateStandardInstance() {
        // mobile product creation logic goes here
    }
}

public class BundleFactory : IAbstractFactory {

    public static Bundle CreateBundle() {
        broadband = BroadbandFactory.CreateStandardInstance();
        phoneline = PhonelineFactory.CreateStandardInstance();
        mobile = MobileFactory.CreateStandardInstance();

        applySomeDiscountOrWhatever(broadband, phoneline, mobile);
    }

    private static void applySomeDiscountOrWhatever(Broadband bb, Phoneline pl, Mobile m) {
        // some logic here
        // maybe manange some variables and invoke some other methods/services/etc.
    }
}

Hope this helps.

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

There are good answers already, but I just want to share this one.

First of all: Provider is the way/recipe to create a service (singleton object) that suppose to be injected by $injector (how AngulaJS goes about IoC pattern).

And Value, Factory, Service and Constant (4 ways) - the syntactic sugar over Provider way/recepie.

There is Service vs Factory part has been covered: https://www.youtube.com/watch?v=BLzNCkPn3ao

Service is all about new keyword actually which as we know does 4 things:

1. creates brand new object
2. links it to its prototype object
3. connects context to this
4. and returns this

And Factory is all about Factory Pattern - contains functions that return Objects like that Service.

1. ability to use other services (have dependencies)
2. service initialization
3. delayed/lazy initialization

And this simple/short video: covers also Provider: https://www.youtube.com/watch?v=HvTZbQ_hUZY (there you see can see how they go from factory to provider)

Provider recipe is used mostly in the app config, before the app has fully started/initialized.

If you use ==, php treats an empty string or array as null. To make the distinction between null and empty, either use === or is_null. So:

if($a === NULL) or if(is_null($a))

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

edit 2015.07.29

Today I'd advise against using + operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number call:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
  return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);

edit 2017.03.09

ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);

For those like me who wonder how legacy apps are treated, I did a bit of testing and computation on the subject.

Thanks to @hannes-sverrisson hint, I started on the assumption that a legacy app is treated with a 320x568 view in iPhone 6 and iPhone 6 plus.

The test was made with a simple black background [email protected] with a white border. The background has a size of 640x1136 pixels, and it is black with an inner white border of 1 pixel.

Below are the screenshots provided by the simulator:

• iPhone 5 simulator : http://i.stack.imgur.com/b2E5K.png
• iPhone 6 simulator : http://i.stack.imgur.com/4Qz8N.png
• iPhone 6 plus simulator : http://i.stack.imgur.com/hQisc.png

On the iPhone 6 screenshot, we can see a 1 pixel margin on top and bottom of the white border, and a 2 pixel margin on the iPhone 6 plus screenshot. This gives us a used space of 1242x2204 on iPhone 6 plus, instead of 1242x2208, and 750x1332 on the iPhone 6, instead of 750x1334.

We can assume that those dead pixels are meant to respect the iPhone 5 aspect ratio:

iPhone 5               640 / 1136 = 0.5634
iPhone 6 (used)        750 / 1332 = 0.5631
iPhone 6 (real)        750 / 1334 = 0.5622
iPhone 6 plus (used)  1242 / 2204 = 0.5635
iPhone 6 plus (real)  1242 / 2208 = 0.5625

Second, it is important to know that @2x resources will be scaled not only on iPhone 6 plus (which expects @3x assets), but also on iPhone 6. This is probably because not scaling the resources would have led to unexpected layouts, due to the enlargement of the view.

However, that scaling is not equivalent in width and height. I tried it with a 264x264 @2x resource. Given the results, I have to assume that the scaling is directly proportional to the pixels / points ratio.

Device         Width scale             Computed width   Screenshot width
iPhone 5        640 /  640 = 1.0                        264 px
iPhone 6        750 /  640 = 1.171875  309.375          309 px
iPhone 6 plus  1242 /  640 = 1.940625  512.325          512 px

Device         Height scale            Computed height  Screenshot height
iPhone 5       1136 / 1136 = 1.0                        264 px
iPhone 6       1332 / 1136 = 1.172535  309.549          310 px
iPhone 6 plus  2204 / 1136 = 1.940141  512.197          512 px

It's important to note the iPhone 6 scaling is not the same in width and height (309x310). This tends to confirm the above theory that scaling is not proportional in width and height, but uses the pixels / points ratio.

I hope this helps.

I would have thought this would have been answered already - but surely what you want is this: box-shadow: 0 0 3px #CC0000;

Example: http://jsfiddle.net/vmzLW/

All answers are great, but they are talking about adding extension method to a specific type of enum.

What if you want to add a method to all enums like returning an int of current value instead of explicit casting?

public static class EnumExtensions
{
    public static int ToInt<T>(this T soure) where T : IConvertible//enum
    {
        if (!typeof(T).IsEnum)
            throw new ArgumentException("T must be an enumerated type");

        return (int) (IConvertible) soure;
    }

    //ShawnFeatherly funtion (above answer) but as extention method
    public static int Count<T>(this T soure) where T : IConvertible//enum
    {
        if (!typeof(T).IsEnum)
            throw new ArgumentException("T must be an enumerated type");

        return Enum.GetNames(typeof(T)).Length;
    }
}

The trick behind IConvertible is its Inheritance Hierarchy see MDSN

Thanks to ShawnFeatherly for his answer

Usually, you do not want to add anything to a Request object, it's better to use collection and put() helper:

function store(Request $request) 
{
    // some additional logic or checking
    User::create(array_merge($request->all(), ['index' => 'value']));
}

Or you could union arrays:

User::create($request->all() + ['index' => 'value']);

But, if you really want to add something to a Request object, do this:

$request->request->add(['variable' => 'value']); //add request

Angular 4 in combination with feature modules (if you are for instance using a shared-module) requires you to also export the ReactiveFormsModule to work.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
  imports:      [
    CommonModule,
    ReactiveFormsModule
  ],
  declarations: [],
  exports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ]
})
export class SharedModule { } 

$.extend($.expr[':'], {
        unchecked: function (obj) {
            return ((obj.type == 'checkbox' || obj.type == 'radio') && !$(obj).is(':checked'));
        }
    });

$("input:checked")
$("input:unchecked")

If you want everything in your post to be as $Variables you can use something like this:

foreach($_POST as $key => $value) { eval("$" . $key . " = " . $value"); }

Note also that vertical-align:top; is often necessary for correct table cell appearance.

css table-cell, contents have unnecessary top margin

There doesn't appear to be an external way to hack the behaviour of the executables.

You could modify the Chrome(ium) executables as this information is obviously compiled in. That approach brings a lot of problems with support and automatic upgrades so you probably want to avoid doing that. You also need to understand how to make the changes to the binaries which is not something most people can pick up in a few days.

If you compile your own browser you are creating a support issue for yourself as you are stuck with a specific revision. If you want to get new features and bug fixes you will have to recompile. All of this involves tracking Chrome development for bugs and build breakages - not something that a web developer should have to do.

I'd follow @BenSwayne's advice for now, but it might be worth thinking about doing some of the work outside of the client (the web browser) and putting it in a background process running on the same or different machines. This process can handle many more connections and you are just responsible for getting the data back from it. Since it is local(ish) you'll get results back quickly even with minimal connections.

project.group is a predefined property. With -P, you can only set project properties that are not predefined. Alternatively, you can set Java system properties (-D).

Concatenate the attribute selectors:

input[name="Sex"][value="M"]

Let me try to explain this with an example.

Consider the following text:

http://stackoverflow.com/
https://stackoverflow.com/questions/tagged/regex

Now, if I apply the regex below over it...

(https?|ftp)://([^/\r\n]+)(/[^\r\n]*)?

... I would get the following result:

Match "http://stackoverflow.com/"
     Group 1: "http"
     Group 2: "stackoverflow.com"
     Group 3: "/"

Match "https://stackoverflow.com/questions/tagged/regex"
     Group 1: "https"
     Group 2: "stackoverflow.com"
     Group 3: "/questions/tagged/regex"

But I don't care about the protocol -- I just want the host and path of the URL. So, I change the regex to include the non-capturing group (?:).

(?:https?|ftp)://([^/\r\n]+)(/[^\r\n]*)?

Now, my result looks like this:

Match "http://stackoverflow.com/"
     Group 1: "stackoverflow.com"
     Group 2: "/"

Match "https://stackoverflow.com/questions/tagged/regex"
     Group 1: "stackoverflow.com"
     Group 2: "/questions/tagged/regex"

See? The first group has not been captured. The parser uses it to match the text, but ignores it later, in the final result.

EDIT:

As requested, let me try to explain groups too.

Well, groups serve many purposes. They can help you to extract exact information from a bigger match (which can also be named), they let you rematch a previous matched group, and can be used for substitutions. Let's try some examples, shall we?

Imagine you have some kind of XML or HTML (be aware that regex may not be the best tool for the job, but it is nice as an example). You want to parse the tags, so you could do something like this (I have added spaces to make it easier to understand):

   \<(?<TAG>.+?)\> [^<]*? \</\k<TAG>\>
or
   \<(.+?)\> [^<]*? \</\1\>

The first regex has a named group (TAG), while the second one uses a common group. Both regexes do the same thing: they use the value from the first group (the name of the tag) to match the closing tag. The difference is that the first one uses the name to match the value, and the second one uses the group index (which starts at 1).

Let's try some substitutions now. Consider the following text:

Lorem ipsum dolor sit amet consectetuer feugiat fames malesuada pretium egestas.

Now, let's use this dumb regex over it:

\b(\S)(\S)(\S)(\S*)\b

This regex matches words with at least 3 characters, and uses groups to separate the first three letters. The result is this:

Match "Lorem"
     Group 1: "L"
     Group 2: "o"
     Group 3: "r"
     Group 4: "em"
Match "ipsum"
     Group 1: "i"
     Group 2: "p"
     Group 3: "s"
     Group 4: "um"
...

Match "consectetuer"
     Group 1: "c"
     Group 2: "o"
     Group 3: "n"
     Group 4: "sectetuer"
...

So, if we apply the substitution string:

$1_$3$2_$4

... over it, we are trying to use the first group, add an underscore, use the third group, then the second group, add another underscore, and then the fourth group. The resulting string would be like the one below.

L_ro_em i_sp_um d_lo_or s_ti_ a_em_t c_no_sectetuer f_ue_giat f_ma_es m_la_esuada p_er_tium e_eg_stas.

You can use named groups for substitutions too, using ${name}.

To play around with regexes, I recommend http://regex101.com/, which offers a good amount of details on how the regex works; it also offers a few regex engines to choose from.

@mplungjan, @eduard-luca

function isDate(str) {    
    var parms = str.split(/[\.\-\/]/);
    var yyyy = parseInt(parms[2],10);
    var mm   = parseInt(parms[1],10);
    var dd   = parseInt(parms[0],10);
    var date = new Date(yyyy,mm-1,dd,12,0,0,0);
    return mm === (date.getMonth()+1) && 
        dd === date.getDate() && 
        yyyy === date.getFullYear();
}

new Date() uses local time, hour 00:00:00 will show the last day when we have "Summer Time" or "DST (Daylight Saving Time)" events.

Example:

new Date(2010,9,17)
Sat Oct 16 2010 23:00:00 GMT-0300 (BRT)

Another alternative is to use getUTCDate().

for(Path p : Files.walk(directoryToDelete).
        sorted((a, b) -> b.compareTo(a)). // reverse; files before dirs
        toArray(Path[]::new))
{
    Files.delete(p);
}

Or if you want to handle the IOException:

Files.walk(directoryToDelete).
    sorted((a, b) -> b.compareTo(a)). // reverse; files before dirs
    forEach(p -> {
        try { Files.delete(p); }
        catch(IOException e) { /* ... */ }
      });

To convert a string to json and the sting is like json. {"phonetype":"N95","cat":"WP"}

String Data=response.getEntity().getText().toString(); // reading the string value 
JSONObject json = (JSONObject) new JSONParser().parse(Data);
String x=(String) json.get("phonetype");
System.out.println("Check Data"+x);
String y=(String) json.get("cat");
System.out.println("Check Data"+y);

The LTrim function to remove leading spaces and the RTrim function to remove trailing spaces from a string variable. It uses the Trim function to remove both types of spaces and means before and after spaces of string.

SELECT LTRIM(RTRIM(REVERSE(' NEXT LEVEL EMPLOYEE ')))

Raise each base in `x1` to the positionally-corresponding power in
`x2`.  `x1` and `x2` must be broadcastable to the same shape.

Parameters
----------
x1 : array_like
    The bases.
x2 : array_like
    The exponents.

Returns
-------

    The bases in `x1` raised to the exponents in `x2`.

Examples
--------
Cube each element in a list.

>>> x1 = range(6)
>>> x1

Below code works for me:

// wait for the window to appear
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.alertIsPresent());

// switch to the file upload window
Alert alert = driver.switchTo().alert();

// enter the filename
alert.sendKeys(fileName);

// hit enter
Robot r = new Robot();
r.keyPress(KeyEvent.VK_ENTER);
r.keyRelease(KeyEvent.VK_ENTER);

// switch back
driver.switchTo().activeElement();

You can combine @Pax and my answers to also get the duration that the mouse has been down for:

var mousedownTimeout,
    mousedown = 0;

document.body.onmousedown = function() {
  mousedown = 0; 
  window.clearInterval(mousedownTimeout);
  mousedownTimeout = window.setInterval(function() { mousedown += 200 }, 200);
}

document.body.onmouseup = function() {
  mousedown = 0;
  window.clearInterval(mousedownTimeout);
}

Then later:

if (mousedown >= 2000) {
  // do something if the mousebutton has been down for at least 2 seconds
}

Transaction can be defined as a collection of task that are considered as minimum processing unit. Each minimum processing unit can not be divided further.

All transaction must contain four properties that commonly known as ACID properties. i.e ACID are the group of properties of any transaction.

• Atomicity :
• Consistency
• Isolation
• Durability

In laymen language we can say:

• Clone: Get a working copy of the remote repository.
• Pull: I am working on this, please get me the new changes that may be updated by others.

Let me quote the manuals first:

perldoc exec():

The exec function executes a system command and never returns-- use system instead of exec if you want it to return

perldoc system():

Does exactly the same thing as exec LIST , except that a fork is done first, and the parent process waits for the child process to complete.

In contrast to exec and system, backticks don't give you the return value but the collected STDOUT.

perldoc `String`:

A string which is (possibly) interpolated and then executed as a system command with /bin/sh or its equivalent. Shell wildcards, pipes, and redirections will be honored. The collected standard output of the command is returned; standard error is unaffected.

Alternatives:

In more complex scenarios, where you want to fetch STDOUT, STDERR or the return code, you can use well known standard modules like IPC::Open2 and IPC::Open3.

Example:

use IPC::Open2;
my $pid = open2(\*CHLD_OUT, \*CHLD_IN, 'some', 'cmd', 'and', 'args');
waitpid( $pid, 0 );
my $child_exit_status = $? >> 8;

Finally, IPC::Run from the CPAN is also worth looking at…

Try this, just an example:

u.UserTypeOptions = new SelectList(new[]
    {
        new { ID="1", Name="name1" },
        new { ID="2", Name="name2" },
        new { ID="3", Name="name3" },
    }, "ID", "Name", 1);

Or

u.UserTypeOptions = new SelectList(new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
        new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
    },"Value","Text");

This worked for me

In JSP, to view the image

<img src="${pageContext.request.contextPath}/resources/images/slide-are.jpg">

In dispatcher-servlet.xml

<mvc:annotation-driven />
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources/" />

As Blazemonger said, #parent, .panel and .collapse have to be direct descendants. However, if You can't change Your html, You can do workaround using bootstrap events and methods with the following code:

$('#your-parent .collapse').on('show.bs.collapse', function (e) {
    var actives = $('#your-parent').find('.in, .collapsing');
    actives.each( function (index, element) {
        $(element).collapse('hide');
    })
})

Render function should be pure, it's mean that it only uses state and props to render, never try to modify the state in render, this usually causes ugly bugs and decreases performance significantly. It's also a good point if you separate data-fetching and render concerns in your React App. I recommend you read this article which explains this idea very well. https://medium.com/@learnreact/container-components-c0e67432e005#.sfydn87nm

This works if the dll is .net or Win32. Reflection methods only work if the dll is .net. Also, if you use reflection, you have the overhead of loading the whole dll into memory. The below method does not load the assembly into memory.

// Get the file version.
FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(@"C:\MyAssembly.dll");

// Print the file name and version number.
Console.WriteLine("File: " + myFileVersionInfo.FileDescription + '\n' +
                  "Version number: " + myFileVersionInfo.FileVersion);

original source

Python documentation for sys.exit([arg])says:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0-127, and produce undefined results otherwise.

Moreover to retrieve the return value of the last executed program you could use the $? bash predefined variable.

Anyway if you put a string as arg in sys.exit() it should be printed at the end of your program output in a separate line, so that you can retrieve it just with a little bit of parsing. As an example consider this:

outputString=`python myPythonScript arg1 arg2 arg3 | tail -0`

Picked this up in the php docs:

<?php
  // split the phrase by any number of commas or space characters,
  // which include " ", \r, \t, \n and \f

  $keywords = preg_split("/[\s,]+/", "hypertext language, programming");
  print_r($keywords);
?>

dgg

will delete everything from your current line to the top of the file.

d is the deletion command, and gg is a movement command that says go to the top of the file, so when used together, it means delete from my current position to the top of the file.

Also

dG

will delete all lines at or below the current one

can't you just subset the columns in either df first?

[i for i in df.columns if i not in df2.columns]

dfNew = merge(df **[i for i in df.columns if i not in df2.columns]**, df2, left_index=True, right_index=True, how='outer')

As mentioned in the other answers, you don't need jQuery to do this; you can just use the standard properties.

However, it seems you don't seem to know the difference between window.location.replace(url) and window.location = url.

1. window.location.replace(url) replaces the current location in the address bar by a new one. The page that was calling the function, won't be included in the browser history. Therefore, on the new location, clicking the back button in your browser would make you go back to the page you were viewing before you visited the document containing the redirecting JavaScript.
2. window.location = url redirects to the new location. On this new page, the back button in your browser would point to the original page containing the redirecting JavaScript.

Of course, both have their use cases, but it seems to me like in this case you should stick with the latter.

P.S.: You probably forgot two slashes after http: on line 2 of your JavaScript:

url = "http://abc.com/" + temp;

I am late for the party. Try replacing as below, mine worked perfectly- "DOMDocument" to "MSXML2.DOMDocument60" "XMLHTTP" to "MSXML2.XMLHTTP60"

use this

for num in range(1,100):
    print("\n")

to be secured, you should execute 3 commands :

cmdkey /generic:"server-address" /user:"username" /pass:"password"
mstsc /v:server-address
cmdkey /delete:server-address

first command to save the credential

second command to open remote desktop

and the third command to delete the credential

all of these commands can be saved in a batch file(bat).

In response to jt. You are correct, the HTML with just the password is susceptible to the Man in the middle attack. However, you can seed it with a GUID from the server ...

$.post(
  'includes/login.php', 
  { user: username, pass: $.md5(password + GUID) },
   onLogin, 
  'json' );

This would defeat the Man-In-The middle ... in that the server would generate a new GUID for each attempt.

Place HiddenField Control in your Form.

<asp:HiddenField ID="hidden" runat="server" />

Create a Property in the Form

protected String LabelProperty
{
    get
    {
        return hidden.Value;
    }
    set
    {
        hidden.Value = value;
    }
}

Update the Hidden Field value from JavaScript

<script>
   function UpdateControl() {
            document.getElementById('<%=hidden.ClientID %>').value = '12';
   }
</script>

Now you can access the Property directly across the Postback. The Label Control updated value will be Lost across PostBack in case it is being used directly in code behind .

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

First, if you branch was created within gc.reflogexpire days (default 90 days, i.e. around 3 months), you can use git log -g <branch> or git reflog show <branch> to find first entry in reflog, which would be creation event, and looks something like below (for git log -g):

Reflog: <branch>@{<nn>} (C R Eator <[email protected]>)
Reflog message: branch: Created from <some other branch>

You would get who created a branch, how many operations ago, and from which branch (well, it might be just "Created from HEAD", which doesn't help much).

That is what MikeSep said in his answer.

Second, if you have branch for longer than gc.reflogexpire and you have run git gc (or it was run automatically), you would have to find common ancestor with the branch it was created from. Take a look at config file, perhaps there is branch.<branchname>.merge entry, which would tell you what branch this one is based on.

If you know that the branch in question was created off master branch (forking from master branch), for example, you can use the following command to see common ancestor:

git show $(git merge-base <branch> master)

You can also try git show-branch <branch> master, as an alternative.

This is what gbacon said in his response.

The answer by @sbk is the way we should do it in spring-boot environment (apart from @Value("${classpath*:})), in my opinion. But in my scenario it was not working if the execute from standalone jar..may be I did something wrong.

But this can be another way of doing this,

InputStream is = this.getClass().getClassLoader().getResourceAsStream(<relative path of the resource from resource directory>);

You separate the values you want to return by commas:

def get_name():
   # you code
   return first_name, last_name

The commas indicate it's a tuple, so you could wrap your values by parentheses:

return (first_name, last_name)

Then when you call the function you a) save all values to one variable as a tuple, or b) separate your variable names by commas

name = get_name() # this is a tuple
first_name, last_name = get_name()
(first_name, last_name) = get_name() # You can put parentheses, but I find it ugly

This works for me:

seekbarPlayer.setMax(mp.getDuration());
getActivity().runOnUiThread(new Runnable() {

    @Override
    public void run() {
        if(mp != null){
            seekbarPlayer.setProgress(mp.getCurrentPosition());
        }
        mHandler.postDelayed(this, 1000);
    }
});

Let's get pedantic, because there are differences that can actually affect your code's behavior. Much of the following is taken from comments made to an "Old New Thing" article.

Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor.

• In C++1998 there are 2 types of initialization: zero and default
• In C++2003 a 3rd type of initialization, value initialization was added.

Assume:

struct A { int m; }; // POD
struct B { ~B(); int m; }; // non-POD, compiler generated default ctor
struct C { C() : m() {}; ~C(); int m; }; // non-POD, default-initialising m

In a C++98 compiler, the following should occur:

• new A - indeterminate value

• new A() - zero-initialize

• new B - default construct (B::m is uninitialized)

• new B() - default construct (B::m is uninitialized)

• new C - default construct (C::m is zero-initialized)

• new C() - default construct (C::m is zero-initialized)

In a C++03 conformant compiler, things should work like so:

• new A - indeterminate value

• new A() - value-initialize A, which is zero-initialization since it's a POD.

• new B - default-initializes (leaves B::m uninitialized)

• new B() - value-initializes B which zero-initializes all fields since its default ctor is compiler generated as opposed to user-defined.

• new C - default-initializes C, which calls the default ctor.

• new C() - value-initializes C, which calls the default ctor.

So in all versions of C++ there's a difference between new A and new A() because A is a POD.

And there's a difference in behavior between C++98 and C++03 for the case new B().

This is one of the dusty corners of C++ that can drive you crazy. When constructing an object, sometimes you want/need the parens, sometimes you absolutely cannot have them, and sometimes it doesn't matter.

1) Requires .NET framework 4 updated to at least 4.0.2. If you have 4.0.2, then you should have

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2

If you have installed latest VS 2012 chances are that you already have 4.0.2. Just verify first.

2) Next you need to have an instance of LocalDb. By default you have an instance whose name is a single v character followed by the LocalDB release version number in the format xx.x. For example, v11.0 represents SQL Server 2012. Automatic instances are public by default. You can also have named instances which are private. Named instances provide isolation from other instances and can improve performance by reducing resource contention with other database users. You can check the status of instances using the SqlLocalDb.exe utility (run it from command line).

3) Next your connection string should look like:

"Server=(localdb)\\v11.0;Integrated Security=true;"

or

"Data Source=(localdb)\\test;Integrated Security=true;"

from your code. They both are the same. Notice the two \\ required because \v and \t means special characters. Also note that what appears after (localdb)\\ is the name of your LocalDb instance. v11.0 is the default public instance, test is something I have created manually which is private.

1. If you have a database (.mdf file) already:

   "Server=(localdb)\\Test;Integrated Security=true;AttachDbFileName= myDbFile;"
   

2. If you don't have a Sql Server database:

   "Server=(localdb)\\v11.0;Integrated Security=true;"
   

And you can create your own database programmatically:

a) to save it in the default location with default setting:

var query = "CREATE DATABASE myDbName;";

b) To save it in a specific location with your own custom settings:

// your db name
string dbName = "myDbName";

// path to your db files:
// ensure that the directory exists and you have read write permission.
string[] files = { Path.Combine(Application.StartupPath, dbName + ".mdf"), 
                   Path.Combine(Application.StartupPath, dbName + ".ldf") };

// db creation query:
// note that the data file and log file have different logical names
var query = "CREATE DATABASE " + dbName +
    " ON PRIMARY" +
    " (NAME = " + dbName + "_data," +
    " FILENAME = '" + files[0] + "'," +
    " SIZE = 3MB," +
    " MAXSIZE = 10MB," +
    " FILEGROWTH = 10%)" +

    " LOG ON" +
    " (NAME = " + dbName + "_log," +
    " FILENAME = '" + files[1] + "'," +
    " SIZE = 1MB," +
    " MAXSIZE = 5MB," +
    " FILEGROWTH = 10%)" +
    ";";

And execute!

A sample table can be loaded into the database with something like:

 @"CREATE TABLE supportContacts 
    (
        id int identity primary key, 
        type varchar(20), 
        details varchar(30)
    );
   INSERT INTO supportContacts
   (type, details)
   VALUES
   ('Email', '[email protected]'),
   ('Twitter', '@sqlfiddle');";

Note that SqlLocalDb.exe utility doesnt give you access to databases, you separately need sqlcmd utility which is sad..

EDIT: moved position of semicolon otherwise error would occur if code was copy/pasted

Based on my experience, even with python 3.3+, an empty __init__.py is still needed sometimes. One situation is when you want to refer a subfolder as a package. For example, when I ran python -m test.foo, it didn't work until I created an empty __init__.py under the test folder. And I'm talking about 3.6.6 version here which is pretty recent.

Apart from that, even for reasons of compatibility with existing source code or project guidelines, its nice to have an empty __init__.py in your package folder.

An alternative that worked for me is to tell Maven to use http: instead of https: when using Maven Central by adding the following to settings.xml:

<settings>
   .
   .
   .
  <mirrors>
    <mirror>
        <id>central-no-ssl</id>
        <name>Central without ssl</name>
        <url>http://repo.maven.apache.org/maven2</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
   .
   .
   .
</settings>

Your mileage may vary of course.

I often use this snippet for simple scripts:

#!/bin/bash

if [ -z "$1" ]; then
    echo -e "\nPlease call '$0 <argument>' to run this command!\n"
    exit 1
fi

Open Terminal and execute commands given below.

cd /etc
subl bashrc

subl denotes Sublime editor. You can replace subl with vi to open bashrc file in default editor. This will workout only if you have bashrc file, created earlier.

I had permissions issue, after given the right permissions i was able to push the contents. I was pushing a existing project into a new git repo.

awk -F '\t' '{ a[$1]++ } END { for (n in a) print n, a[n] } ' test.csv

Using the hyperref package, you could also declare a new command by using \newcommand{\secref}[1]{\autoref{#1}. \nameref{#1}} in the pre-amble. Placing \secref{section:my} in the text generates: 1. My section.

As an addition to Barry's answer. The sp_help can also be used by itself to iterate all of the objects in a particular database. You also have sp_helptext for your arsenal, which scripts out programmatic elements, like stored procedures.

Gary Hole answer is very relevant to solve the problem if the code is written in such way

obj.prop("style","border:1px red solid;")

Since the prop function return CSSStyleDeclaration object, above code will not working properly in some browser(tested with IE8 with Chrome Frame Plugin in my case).

Thus changing it into following code

obj.prop("style").cssText = "border:1px red solid;"

solved the problem.

This will definitely work for you...

ArrayList<String> list = new ArrayList<String>();

list.add(textview.getText().toString());
list.add("B");
list.add("C");

Try

sdiff file1 file2

It ususally works much better in most cases for me. You may want to sort files prior, if order of lines is not important (e.g. some text config files).

For example,

sdiff -w 185 file1.cfg file2.cfg

<html:form name="Form" type="abc" action="abc.do" method="get" onsubmit="return false;">

method="get" - resolves the problem.

if method="post" then only warning comes.

Reason:You are pushing to a Non-Bare Repository

There are two types of repositories: bare and non-bare

Bare repositories do not have a working copy and you can push to them. Those are the types of repositories you get in Github! If you want to create a bare repository, you can use

git init --bare

So, in short, you can't push to a non-bare repository (Edit: Well, you can't push to the currently checked out branch of a repository. With a bare repository, you can push to any branch since none are checked out. Although possible, pushing to non-bare repositories is not common). What you can do, is to fetch and merge from the other repository. This is how the pull request that you can see in Github works. You ask them to pull from you, and you don't force-push into them.

Update: Thanks to VonC for pointing this out, in the latest git versions (currently 2.3.0), pushing to the checked out branch of a non-bare repository is possible. Nevertheless, you still cannot push to a dirty working tree, which is not a safe operation anyway.

In my case, when using IntelliJ, I had multiple modules in the project. The main module was dependent on another module which had the maven dependencies on Spring.

The main module had Entitys and so did the second module. But when I ran the main module, only the Entitys from the second module got recognized as managed classes.

I then added Spring dependencies on the main module as well, and guess what? It recognized all the Entitys.

I was working on a nice defect last time and was wondering more about how to use properly hover property for A tag link and for IE browser. A strange thing for me was that IE was not able to capture A tag link element based on a simple A selector. So, I found out how to even force capturing A tag element and I spotted that we must use more specifc CSS selector. Here is an example below - It works perfect:

li a[href]:hover {...}

You need to use LogLevel rewrite:trace3 to your httpd.conf in newer version http://httpd.apache.org/docs/2.4/mod/mod_rewrite.html#logging

For those of you using Centos (and perhaps other linux distibutions), you need to make sure that its FW (iptables) allows for port 80 or any other port you want.

See here on how to completely disable it (for testing purposes only!). And here for specific rules

to truncate a decimal I've used the follow code:

<th><%#= sprintf("%0.01f",prom/total) %><!--1dec,aprox-->
    <% if prom == 0 or total == 0 %>
        N.E.
    <% else %>
        <%= Integer((prom/total).to_d*10)*0.1 %><!--1decimal,truncado-->
    <% end %>
        <%#= prom/total %>
</th>

If you want to truncate to 2 decimals, you should use Integr(a*100)*0.01

Use Array list http://developer.android.com/reference/java/util/ArrayList.html

There should also be <category android:name="android.intent.category.BROWSABLE"/> added to the intent filter to make the activity recognized properly from the link.

HTML

<input [(ngModel)] = "searchTerm" (ngModelChange) = "search()"/>
<div *ngFor = "let item of items">{{item.name}}</div>

Component

search(): void {
    let term = this.searchTerm;
    this.items = this.itemsCopy.filter(function(tag) {
        return tag.name.indexOf(term) >= 0;
    }); 
}

Note that this.itemsCopy is equal to this.items and should be set before doing the search.

This error means that the value indexed by the key "l_messages" is not of type hash, but rather something else. You've probably set it to that other value earlier in your code. Try various other value-getter commands, starting with GET, to see which one works and you'll know what type is actually here.

If you are designing your Javafx application using SceneBuilder then use -fx-text-fill(if not available as option then write it in style input box) as style and give the color you want,it will change the text color of your Textfield.

I came here for the same problem and solved it in this way.

before PHP 5.3

session_register("name");

since PHP 5.3

$_SESSION['name'] = $name;

Try this

 <div id="app">
  <p>
    <label for='terms'>
      <input id='terms' type='checkbox' v-model='terms' /> Click me to enable
    </label>
  </p>
  <input :disabled='isDisabled'></input>
</div>

vue js

new Vue({
  el: '#app',
  data: {
    terms: false
  },
  computed: {
    isDisabled: function(){
        return !this.terms;
    }
  }
})

1st Reason could be the ending tag of your application's web.xml file which could not have been closed properly.

web.xml might be ending with <web-app>, but must end with </web-app>

2nd Reason which worked in my case could be the lib folder of your tomcat must contain the supporting jar file of your database.

ojdbc on case of Oracle or sqljdbc in case of SqlServer

Besides the mentioned fact that JSX tags are not standard javascript, the reason I use .jsx extension is because with it Emmet still works in the editor - you know, that useful plugin that expands html code, for example ul>li into

<ul>
  <li></li>
</ul>

cv::Mat m;
m.create(10, 10, CV_32FC3);

float *array = (float *)malloc( 3*sizeof(float)*10*10 );
cv::MatConstIterator_<cv::Vec3f> it = m.begin<cv::Vec3f>();
for (unsigned i = 0; it != m.end<cv::Vec3f>(); it++ ) {
    for ( unsigned j = 0; j < 3; j++ ) {
        *(array + i ) = (*it)[j];
        i++;
    }
}

Now you have a float array. In case of 8 bit, simply change float to uchar, Vec3f to Vec3b and CV_32FC3 to CV_8UC3.

Predicate<Client> hasSameNameAsOneUser = 
    c -> users.stream().anyMatch(u -> u.getName().equals(c.getName()));

return clients.stream()
              .filter(hasSameNameAsOneUser)
              .collect(Collectors.toList());

But this is quite inefficient, because it's O(m * n). You'd better create a Set of acceptable names:

Set<String> acceptableNames = 
    users.stream()
         .map(User::getName)
         .collect(Collectors.toSet());

return clients.stream()
              .filter(c -> acceptableNames.contains(c.getName()))
              .collect(Collectors.toList());

Also note that it's not strictly equivalent to the code you have (if it compiled), which adds the same client twice to the list if several users have the same name as the client.

You don't have jdk1.7.0_17 in your PATH - check again. There is only JRE which may not contain 'javac' compiler.

Besides it is best to set JAVA_HOME variable, and then include it in PATH.

A valid domain is for me something I'm able to register or at least something that looks like I could register it. This is the reason why I like to separate this from "localhost"-names.

And finally I was interested in the main question if avoiding Regex would be faster and this is my result:

<?php
function filter_hostname($name, $domain_only=false) {
    // entire hostname has a maximum of 253 ASCII characters
    if (!($len = strlen($name)) || $len > 253
    // .example.org and localhost- are not allowed
    || $name[0] == '.' || $name[0] == '-' || $name[ $len - 1 ] == '.' || $name[ $len - 1 ] == '-'
    // a.de is the shortest possible domain name and needs one dot
    || ($domain_only && ($len < 4 || strpos($name, '.') === false))
    // several combinations are not allowed
    || strpos($name, '..') !== false
    || strpos($name, '.-') !== false
    || strpos($name, '-.') !== false
    // only letters, numbers, dot and hypen are allowed
/*
    // a little bit slower
    || !ctype_alnum(str_replace(array('-', '.'), '', $name))
*/
    || preg_match('/[^a-z\d.-]/i', $name)
    ) {
        return false;
    }
    // each label may contain up to 63 characters
    $offset = 0;
    while (($pos = strpos($name, '.', $offset)) !== false) {
        if ($pos - $offset > 63) {
            return false;
        }
        $offset = $pos + 1;
    }
    return $name;
}
?>

Benchmark results compared with velcrow 's function and 10000 iterations (complete results contains many code variants. It was interesting to find the fastest.):

filter_hostname($domain);// $domains: 0.43556308746338 $real_world: 0.33749794960022
is_valid_domain_name($domain);// $domains: 0.81832790374756 $real_world: 0.32248711585999

$real_world did not contain extreme long domain names to produce better results. And now I can answer your question: With the usage of ctype_alnum() it would be possible to realize it without regex, but as preg_match() was faster I would prefer that.

If you don't like the fact that "local.host" is a valid domain name use this function instead that valids against a public tld list. Maybe someone finds the time to combine both.

For what its worth, I couldn't get it working on IE7/8/9 and the multiple declaration option didn't make any difference.

The fix for me was as a result of the instructions on the Technical Considerations Page where it highlights...

For best display in IE, make the stylesheet 'link' tag the first element in the HTML 'head' section.

Works across IE7/8/9 for me now.

Your choices are simple:

1. Write the code to do the conversion (ie, divide by milliSecondsPerDay to get days and use the modulus to divide by milliSecondsPerHour to get hours and use the modulus to divide by milliSecondsPerMinute and divide by 1000 for seconds. milliSecondsPerMinute = 60000, milliSecondsPerHour = 60 * milliSecondsPerMinute, milliSecondsPerDay = 24 * milliSecondsPerHour.
2. Use an operating routine of some kind. UNIX and Windows both have structures that you can get from a Ticks or seconds type value.

Just use this website: http://ticons.fokkezb.nl :)

It makes it easier for you, and generates the correct sizes directly

You could do it like this :

bool areFieldEmpty = YES;
//Label to leave the loops
outer_loop;

//For each input (except of submit) in your form

    public static class XShortCut

        /// Creates a shortcut in the startup folder from a exe as found in the current directory.
        /// </summary>

        /// <param name="startIn">The shortcut's "Start In" folder</param>
        /// <param name="description">The shortcut's description</param>
        /// <returns>The folder path where created</returns>
        public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description)
        {
            var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath();
            var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk";
            var targetPath = Environment.CurrentDirectory + @"\" + exeName;
            XFile.Delete(linkPath);
            Create(linkPath, targetPath, startIn, description);
            return startupFolderPath;
        }

        /// <summary>
        /// Create a shortcut
        /// </summary>
        /// <param name="fullPathToLink">the full path to the shortcut to be created</param>
        /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param>
        /// <param name="startIn">Start in this folder</param>
        /// <param name="description">Description for the link</param>
        public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description)
        {
            var shell = new WshShell();
            var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink);
            link.IconLocation = fullPathToTargetExe;
            link.TargetPath = fullPathToTargetExe;
            link.Description = description;
            link.WorkingDirectory = startIn;
            link.Save();
        }
    }
}

And an example of use:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory,
    "Starts some executable in the current directory of application");

1st parm sets the exe name (found in the current directory) 2nd parm is the "Start In" folder and 3rd parm is the shortcut description.

The naming convention of the link leaves no ambiguity as to what it will do. To test the link just double click it.

Final Note: the application itself (target) must have an ICON image associated with it. The link is easily able to locate the ICON within the exe. If the target application has more than one icon, you may open the link's properties and change the icon to any other found in the exe.

Scala

Scala evolved out of a pure functional language known as Funnel and represents a clean-room implementation of almost all Java's syntax, differing only where a clear improvement could be made or where it would compromise the functional nature of the language. Such differences include singleton objects instead of static methods, and type inference.

Much of this was based on Martin Odersky's prior work with the Pizza language. The OO/FP integration goes far beyond mere closures and has led to the language being described as post-functional.

Despite this, it's the closest to Java in many ways. Mainly due to a combination of OO support and static typing, but also due to a explicit goal in the language design that it should integrate very tightly with Java.

Groovy

Groovy explicitly tackles two of Java's biggest criticisms by

• being dynamically typed, which removes a lot of boilerplate and
• adding closures to the language.

It's perhaps syntactically closest to Java, not offering some of the richer functional constructs that Clojure and Scala provide, but still offering a definite evolutionary improvement - especially for writing script-syle programs.

Groovy has the strongest commercial backing of the three languages, mostly via springsource.

Clojure

Clojure is a functional language in the LISP family, it's also dynamically typed.

Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this.

Syntactically, it's also the furthest of the three languages from typical Java code.

I also have to disclose that I'm most acquainted with Scala :)

  //create activity object to get activity from Activity class for use to content resolver
    private final Activity ActivityObj;

  //create constructor with ActivityObj to get activity from Activity class
    public RecyclerViewAdapterClass(Activity activityObj) {
        this.ActivityObj = activityObj;
    }


     ActivityObj.getContentResolver(),.....,.....,null);

After reading this and troubleshooting the same issues, I agree that it is related to headings (h1 for sure, havent played with any others), also browser styles adding margins and paddings with clever rules that are hard to find and over-ride.

I have adapted a technique used to apply the box-sizing property properly to margins and paddings. the original article for box-sizing is located at CSS-Tricks :

html {
margin: 0;
padding: 0;
}
*, *:before, *:after {
margin: inherit;
padding: inherit;
}

So far it is exactly the trick for not using complex resets and makes applying a design much easier for myself anyways. Hope it helps.

Since SVG is basically code, you need just contents. I used PHP to obtain content, but you can use whatever you want.

<?php
$content    = file_get_contents($pathToSVG);
?>

Then, I've printed content "as is" inside a div container

<div class="fill-class"><?php echo $content;?></div>

To finnaly set rule to container's SVG childs on CSS

.fill-class > svg { 
    fill: orange;
}

I got this results with a material icon SVG:

1. Mozilla Firefox 59.0.2 (64-bit) Linux

2. Google Chrome66.0.3359.181 (Build oficial) (64 bits) Linux

3. Opera 53.0.2907.37 Linux

I found this implementation very easy to use. Also has a generous BSD-style license:

jsSHA: https://github.com/Caligatio/jsSHA

I needed a quick way to get the hex-string representation of a SHA-256 hash. It only took 3 lines:

var sha256 = new jsSHA('SHA-256', 'TEXT');
sha256.update(some_string_variable_to_hash);
var hash = sha256.getHash("HEX");

A small addition to the answers already posted, here's a Venn's diagram to sum up the theory (from Prateek Joshi's beautiful explanation):

And an example (also from Prateek's website):

Just put a line break into your text.

You don't add lines as a method. Multiline just supports the use of line breaks.

Here's another library:

https://github.com/eltos/SimpleDialogFragments

Features color wheel and pallet picker dialogs

To complement the previous stated solution, use:

str = str.replace("%", "%%");

You can get a list of all matching elements with a list comprehension:

[x for x in myList if x.n == 30]  # list of all elements with .n==30

If you simply want to determine if the list contains any element that matches and do it (relatively) efficiently, you can do

def contains(list, filter):
    for x in list:
        if filter(x):
            return True
    return False

if contains(myList, lambda x: x.n == 3)  # True if any element has .n==3
    # do stuff

you may also do

git pull -r origin master

fix merge conflicts if any

git rebase --continue

-r is for rebase. This will make you branch structure from

        v  master       
o-o-o-o-o
     \o-o-o
          ^ other branch

to

        v  master       
o-o-o-o-o-o-o-o
              ^ other branch

This will lead to a cleaner history. Note: In case you have already pushed your other-branch to origin( or any other remote), you may have to force push your branch after rebase.

git push -f origin other-branch

You can use.`

        Model.update({
            'type': "newuser"
        }, {
            $set: {
                email: "[email protected]",
                phoneNumber:"0123456789"
            }
        }, {
            multi: true
        },
        function(err, result) {
            console.log(result);
            console.log(err);
        })  `

Since you are using Access to compose the query, you have to stick to Access's version of SQL.

To choose between several different return values, use the switch() function. So to translate and extend your example a bit:

select switch(
  age > 40, 4,
  age > 25, 3,
  age > 20, 2,
  age > 10, 1,
  true, 0
) from demo

The 'true' case is the default one. If you don't have it and none of the other cases match, the function will return null.

The Office website has documentation on this but their example syntax is VBA and it's also wrong. I've given them feedback on this but you should be fine following the above example.

There are a few ways to do this, as mentioned above, but in my experience the best way to manipulate an XHR request and resend is to use chrome dev tools to copy the request as cURL request (right click on the request in the network tab) and to simply import into the Postman app (giant import button in the top left).

I couldn't use any of the other answers in my case. I used the native java Timer instead.

new Timer().schedule(new TimerTask() {          
    @Override
    public void run() {
        // this code will be executed after 2 seconds       
    }
}, 2000);

Yes you can upload your git repo from vs code. You have to get in the projects working directory and type git init in the terminal. Then add the files to your repository like you do with regular git commits.

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

I had a "fatal : bad revision" with Idea / Webstorm because I had a git directory inside another, without using properly submodules or subtrees.

I checked for .git dirs with :

find ./ -name '.git' -print

How about HKEY_CLASSES_ROOT\Word.Application\CurVer?

Per Martin Konicek's comment, to fully disable the selection of the items in the simplest manner:

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="Focusable" Value="false"/>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

However if you still require the functionality of the ListView, like being able to select an item, then you can visually disable the styling of the selected item like so:

You can do this a number of ways, from changing the ListViewItem's ControlTemplate to just setting a style (much easier). You can create a style for the ListViewItems using the ItemContainerStyle and 'turn off' the background and border brush when it is selected.

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsSelected"
                         Value="True">
                    <Setter Property="Background"
                            Value="{x:Null}" />
                    <Setter Property="BorderBrush"
                            Value="{x:Null}" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

Also, unless you have some other way of notifying the user when the item is selected (or just for testing) you can add a column to represent the value:

<GridViewColumn Header="IsSelected"
                DisplayMemberBinding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem}}, Path=IsSelected}" />

For 2020 ..

easy as pie, tap preferences (eg, apple-comma on a Mac),

they added it right there:

Turn "off" for normal behavior. (IE, to avoid the "automatic closing" behavior.)

awk 'NF' filename

awk 'NF > 0' filename

sed -i '/^$/d' filename

awk '!/^$/' filename

awk '/./' filename

The NF also removes lines containing only blanks or tabs, the regex /^$/ does not.

You do not have permissions to access the file. Please be sure whether you can access the file in that drive.

string route= @"E:\Sample.text";
FileStream fs = new FileStream(route, FileMode.Create);

You have to provide the file name to create. Please try this, now you can create.

The Address property of a cell can get this for you:

MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)

returns A1.

The other way around can be done with the Row and Column property of Range:

MsgBox Range("A1").Row & ", " & Range("A1").Column

returns 1,1.

You need to define an AbstractBinder and register it in your JAX-RS application. The binder specifies how the dependency injection should create your classes.

public class MyApplicationBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(MyService.class).to(MyService.class);
    }
}

When @Inject is detected on a parameter or field of type MyService.class it is instantiated using the class MyService. To use this binder, it need to be registered with the JAX-RS application. In your web.xml, define a JAX-RS application like this:

<servlet>
  <servlet-name>MyApplication</servlet-name>
  <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>com.mypackage.MyApplication</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>MyApplication</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

Implement the MyApplication class (specified above in the init-param).

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        register(new MyApplicationBinder());
        packages(true, "com.mypackage.rest");
    }
}

The binder specifying dependency injection is registered in the constructor of the class, and we also tell the application where to find the REST resources (in your case, MyResource) using the packages() method call.

In [6]: x = -2
In [7]: x
Out[7]: -2

In [8]: abs(x)
Out[8]: 2

Actually abs will return the absolute value of any number. Absolute value is always a non-negative number.

This might work...

from p in db.products
    select new
    {
        Owner = (p.price > 0 ?
            from q in db.Users select q.Name :
            from r in db.ExternalUsers select r.Name)
    }

Using the .not() method with selecting an entire element is also an option.

This way could be usefull if you want to do another action with that element directly.

$(".thisClass").not($("#thisId")[0].doAnotherAction()).doAction();

use test1

insert into employee(deptid) select deptid from test2.dbo.employee

DataFrame.sort is deprecated; use DataFrame.sort_values.

Changing mvn clean to mvn clean --file *.pom fixed this issue for me.

In order to make a pull request you need to do the following steps:

1. Fork a repository (to which you want to make a pull request). Just click the fork button the the repository page and you will have a separate github repository preceded with your github username.
2. Clone the repository to your local machine. The Github software that you installed on your local machine can do this for you. Click the clone button beside the repository name.
3. Make local changes/commits to the files
4. sync the changes
5. go to your github forked repository and click the "Compare & Review" green button besides the branch button. (The button has icon - no text)
6. A new page will open showing your changes and then click the pull request link, that will send the request to the original owner of the repository you forked.

It took me a while to figure this, hope this will help someone.

You must add an id that auto-increment for each row, after that you can delet the row by its id. so your table will have an unique id for each row and the id_user, id_product ecc...

Use this with WPF:

Cursor = Cursors.Wait;

// Your Heavy work here

Cursor = Cursors.Arrow;

C++14 brings generic lambdas. Meaning we can use std::for_each very easily:

std::map<int, int> myMap{{1, 2}, {3, 4}, {5, 6}, {7, 8}};

std::for_each(myMap.begin(), myMap.end(), [](const auto &myMapPair) {
    std::cout << "first " << myMapPair.first << " second "
              << myMapPair.second << std::endl;
});

I think std::for_each is sometimes better suited than a simple range based for loop. For example when you only want to loop through a subset of a map.

In regards to your error and what's missing in your code. m is a name which is not defined for getmd5() function.

No offence, I know you are a beginner, but your code is all over the place. Let's look at your issues one by one :)

First, you are not using hashlib.md5.hexdigest() method correctly. Please refer explanation on hashlib functions in Python Doc Library. The correct way to return MD5 for provided string is to do something like this:

>>> import hashlib
>>> hashlib.md5("filename.exe").hexdigest()
'2a53375ff139d9837e93a38a279d63e5'

However, you have a bigger problem here. You are calculating MD5 on a file name string, where in reality MD5 is calculated based on file contents. You will need to basically read file contents and pipe it though MD5. My next example is not very efficient, but something like this:

>>> import hashlib
>>> hashlib.md5(open('filename.exe','rb').read()).hexdigest()
'd41d8cd98f00b204e9800998ecf8427e'

As you can clearly see second MD5 hash is totally different from the first one. The reason for that is that we are pushing contents of the file through, not just file name.

A simple solution could be something like that:

# Import hashlib library (md5 method is part of it)
import hashlib

# File to check
file_name = 'filename.exe'

# Correct original md5 goes here
original_md5 = '5d41402abc4b2a76b9719d911017c592'  

# Open,close, read file and calculate MD5 on its contents 
with open(file_name) as file_to_check:
    # read contents of the file
    data = file_to_check.read()    
    # pipe contents of the file through
    md5_returned = hashlib.md5(data).hexdigest()

# Finally compare original MD5 with freshly calculated
if original_md5 == md5_returned:
    print "MD5 verified."
else:
    print "MD5 verification failed!."

Please look at the post Python: Generating a MD5 checksum of a file. It explains in detail a couple of ways how it can be achieved efficiently.

Best of luck.

How to include the jars of your project into your runnable jar:

I'm using Eclipse Version: 3.7.2 running on Ubuntu 12.10. I'll also show you how to make the build.xml so you can do the ant jar from command line and create your jar with other imported jars extracted into it.

Basically you ask Eclipse to construct the build.xml that imports your libraries into your jar for you.

1. Fire up Eclipse and make a new Java project, make a new package 'mypackage', add your main class: Runner Put this code in there.

   

2. Now include the mysql-connector-java-5.1.28-bin.jar from Oracle which enables us to write Java to connect to the MySQL database. Do this by right clicking the project -> properties -> java build path -> Add External Jar -> pick mysql-connector-java-5.1.28-bin.jar.

3. Run the program within eclipse, it should run, and tell you that the username/password is invalid which means Eclipse is properly configured with the jar.

4. In Eclipse go to File -> Export -> Java -> Runnable Jar File. You will see this dialog:

   

   Make sure to set up the 'save as ant script' checkbox. That is what makes it so you can use the commandline to do an ant jar later.

5. Then go to the terminal and look at the ant script:

   

So you see, I ran the jar and it didn't error out because it found the included mysql-connector-java-5.1.28-bin.jar embedded inside Hello.jar.

Look inside Hello.jar: vi Hello.jar and you will see many references to com/mysql/jdbc/stuff.class

To do ant jar on the commandline to do all this automatically: Rename buildant.xml to build.xml, and change the target name from create_run_jar to jar.

Then, from within MyProject you type ant jar and boom. You've got your jar inside MyProject. And you can invoke it using java -jar Hello.jar and it all works.

A simple answer:

To expand on the POSIX variables answer, note that you can do more interesting patterns. So for the case detailed here, you could simply do this:

tar -zxvf $1
cd ${1%.tar.*}

That will cut off the last occurrence of .tar.<something>.

More generally, if you wanted to remove the last occurrence of .<something>.<something-else> then

${1.*.*}

should work fine.

The link the above answer appears to be dead. Here's a great explanation of a bunch of the string manipulation you can do directly in Bash, from TLDP.

When you don't have a PC on hand, you could use Eruda, which is devtools for mobile browsers https://github.com/liriliri/eruda
It is provided as embeddable javascript and also a bookmarklet (pasting bookmarklet in chrome removes the javascript: prefix, so you have to type it yourself)

genrsa has been replaced by genpkey & when run manually in a terminal it will prompt for a password:

openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096

However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell script:

get_passwd() {
    local passwd=
    echo -ne "Enter passwd for private key: ? "; read -s passwd
    openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}

I had faced the similar error when supporting one application. It was about the generated classes for a SOAP Webservice.

The issue was caused due to the missing classes. When javax.xml.bind.Marshaller was trying to marshal the jaxb object it was not finding all dependent classes which were generated by using wsdl and xsd. after adding the jar with all the classes at the class path the issue was resolved.

Under Jenkins it complains like :

/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/ doesn’t look like a JDK directory

Reason : Unable to found any Dev Kit for JDK.

Solution:

Please make sure to install openjdk-devel package as well along with your JDK-1.8* version and reexport with : # source ~/.bash_profile

I've been playing around with another option that uses blobs. I've managed to get it to download text documents, and I've downloaded PDF's (However they are corrupted).

Using the blob API you will be able to do the following:

$.post(/*...*/,function (result)
{
    var blob=new Blob([result]);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="myFileName.txt";
    link.click();

});

This is IE 10+, Chrome 8+, FF 4+. See https://developer.mozilla.org/en-US/docs/Web/API/URL.createObjectURL

It will only download the file in Chrome, Firefox and Opera. This uses a download attribute on the anchor tag to force the browser to download it.

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

Basically, a webservice is a method of communication between two machines while an API is an exposed layer allowing you to program against something.

You could very well have an API and the main method of interacting with that API is via a webservice.

The technical definitions (courtesy of Wikipedia) are:

API

An application programming interface (API) is a set of routines, data structures, object classes and/or protocols provided by libraries and/or operating system services in order to support the building of applications.

Webservice

A Web service (also Web Service) is defined by the W3C as "a software system designed to support interoperable machine-to-machine interaction over a network"

Try this:

public void paint (Graphics g) {    
    Rectangle r = new Rectangle(xPos,yPos,width,height);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());  
}

[edit]

// With explicit casting
public void paint (Graphics g) {    
        Rectangle r = new Rectangle(xPos, yPos, width, height);
        g.fillRect(
           (int)r.getX(),
           (int)r.getY(),
           (int)r.getWidth(),
           (int)r.getHeight()
        );  
    }

You can install apps in simulator from Xcode 8.2

From Xcode 8.2,You can install an app (*.app) by dragging any previously built app bundle into the simulator window.

Note: You cannot install apps from the App Store in simulation environments.

Here is my solution to a modal that can be rendered on any screen and initialized in App.tsx

ModalComponent.tsx

import React, { Component } from 'react';
import { Modal, Text, TouchableHighlight, View, StyleSheet, Platform } from 'react-native';
import EventEmitter from 'events';
// I keep localization files for strings and device metrics like height and width which are used for styling 
import strings from '../../config/strings';
import metrics from '../../config/metrics';

const emitter = new EventEmitter();
export const _modalEmitter = emitter

export class ModalView extends Component {
    state: {
        modalVisible: boolean,
        text: string, 
        callbackSubmit: any, 
        callbackCancel: any,
        animation: any
    }

    constructor(props) {
        super(props)
        this.state = {
            modalVisible: false,
            text: "", 
            callbackSubmit: (() => {}), 
            callbackCancel: (() => {}),
            animation: new Animated.Value(0)
        } 
    }

    componentDidMount() {
        _modalEmitter.addListener(strings.modalOpen, (event) => {

    closeModal = () => {

closeModal() {

}

Hope I was able to help some of you, I used a very similar structure for in-app notifications

Happy coding

If you just want to check string equality, use the == operator. Determining whether two strings are equal is simpler than finding an ordering (which is what compare() gives,) so it might be better performance-wise in your case to use the equality operator.

Longer answer: The API provides a method to check for string equality and a method to check string ordering. You want string equality, so use the equality operator (so that your expectations and those of the library implementors align.) If performance is important then you might like to test both methods and find the fastest.

The placeholder attribute

You're looking for the placeholder attribute. Use it like any other attribute inside your ASP.net control:

<asp:textbox id="txtWithHint" placeholder="hint" runat="server"/>

Don't bother about your IDE (i.e. Visual Studio) maybe not knowing the attribute. Attributes which are not registered with ASP.net are passed through and rendered as is. So the above code (basically) renders to:

<input type="text" placeholder="hint"/>

Using placeholder in resources

A fine way of applying the hint to the control is using resources. This way you may have localized hints. Let's say you have an index.aspx file, your App_LocalResources/index.aspx.resx file contains

<data name="WithHint.placeholder">
    <value>hint</value>
</data>

and your control looks like

<asp:textbox id="txtWithHint" meta:resourcekey="WithHint" runat="server"/>

the rendered result will look the same as the one in the chapter above.

Add attribute in code behind

Like any other attribute you can add the placeholder to the AttributeCollection:

txtWithHint.Attributes.Add("placeholder", "hint");

I am not sure what the last line means. Does it mean, I read the file, create multiple Movie objects. Then make a vector of pointers where each element (pointer) points to one of those Movie objects?

I would guess this is what is intended. The intent is probably that you read the data for one movie, allocate an object with new, fill the object in with the data, and then push the address of the data onto the vector (probably not the best design, but most likely what's intended anyway).

I tried in the following way

aws s3 ls s3://Bucket1/folder1/2019/ --recursive |grep filename.csv

This outputs the actual path where the file exists

2019-04-05 01:18:35     111111 folder1/2019/03/20/filename.csv

Let's say you have input data x and you want to classify the data into labels y. A generative model learns the joint probability distribution p(x,y) and a discriminative model learns the conditional probability distribution p(y|x) - which you should read as "the probability of y given x".

Here's a really simple example. Suppose you have the following data in the form (x,y):

(1,0), (1,0), (2,0), (2, 1)

p(x,y) is

      y=0   y=1
     -----------
x=1 | 1/2   0
x=2 | 1/4   1/4

p(y|x) is

      y=0   y=1
     -----------
x=1 | 1     0
x=2 | 1/2   1/2

If you take a few minutes to stare at those two matrices, you will understand the difference between the two probability distributions.

The distribution p(y|x) is the natural distribution for classifying a given example x into a class y, which is why algorithms that model this directly are called discriminative algorithms. Generative algorithms model p(x,y), which can be transformed into p(y|x) by applying Bayes rule and then used for classification. However, the distribution p(x,y) can also be used for other purposes. For example, you could use p(x,y) to generate likely (x,y) pairs.

From the description above, you might be thinking that generative models are more generally useful and therefore better, but it's not as simple as that. This paper is a very popular reference on the subject of discriminative vs. generative classifiers, but it's pretty heavy going. The overall gist is that discriminative models generally outperform generative models in classification tasks.

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

For EXAMPLE

Your Path = /home/serverID_name/www/your_route_Dir/

THIS_is_the_DIR_I_Want

A Soultion that WORKS:

$url = dirname(\__FILE__);
$array = explode('\\\',$url);
$count = count($array);
echo $array[$count-1];

You can just use []:

var valueAtIndex1 = myValues[1];

I figured out a simplest way. You don't need to install package ThenInclude.EF or you don't need to use ThenInclude for all nested navigation properties. Just do like as shown below, EF will take care rest for you. example:

var thenInclude = context.One.Include(x => x.Twoes.Threes.Fours.Fives.Sixes)
.Include(x=> x.Other)
.ToList();

Not exactly the most robust password protection here, so please don't use this to protect credit card numbers or something very important.

Simply drop all of the following code into a file called (secure.php), change the user and pass from "admin" to whatever you want. Then right under those lines where it says include("secure.html"), simply replace that with the filename you want them to be able to see.

They will access this page at [YouDomain.com/secure.php] and then the PHP script will internally include the file you want password protected so they won't know the name of that file, and can't later just access it directly bypassing the password prompt.

If you would like to add a further level of protection, I would recommend you take your (secure.html) file outside of your site's root folder [/public_html], and place it on the same level as that directory, so that it is not inside the directory. Then in the PHP script where you are including the file simply use ("../secure.html"). That (../) means go back a directory to find the file. Doing it this way, the only way someone can access the content that's on the (secure.html) page is through the (secure.php) script.

<?php
$user = $_POST['user'];
$pass = $_POST['pass'];

if($user == "admin"
&& $pass == "admin")
{
        include("secure.html");
}
else
{
    if(isset($_POST))
    {?>

            <form method="POST" action="secure.php">
            User <input type="text" name="user"></input><br/>
            Pass <input type="password" name="pass"></input><br/>
            <input type="submit" name="submit" value="Go"></input>
            </form>
    <?}
}
?>

Also, you could try triggering a mouseover.

$("#btn").click(function() {
   $("#link").trigger("mouseover");
});

Not sure if this will work for your specific scenario, but I've had success triggering mouseover instead of hover for various cases.

There can be many things:
First attempt, make a select of this field in its source table;
Check the instance of the sql script window, you may be in a different instance;
Check if your join is correct;
Verify query ambiguity, maybe you are making a wrong table reference
Of these checks, run the T-sql script again

Use the .IndexOf() method of the list. Specs for the method can be found on MSDN.

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

To Install

adb install -r exampleApp.apk

(The -r makes it replace the existing copy, add an -s if installing on an emulator)

Make sure the app is signed the same and is the same debug/release variant

Bonus

I set up an alias in my ~/.bash_profile, to make it a 2char command.

alias bi="gradlew && adb install -r exampleApp.apk"

(Short for Build and Install)

You can also do like this-

 std::map<char, int>::iterator it = m.find('c'); 
 if (it != m.end())
 (*it).second = 42;

try this

<script type="text/javascript">
window.onload = function(){


var auto_refresh = setInterval(
function ()
{
$('.View').html('');
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds

}
</script>

I write a code to read file line by line to meet my demand which different line have different data type follow articles: read-line-by-line-of-a-file-in-r and determining-number-of-linesrecords. And it should be a better solution for big file, I think. My R version (3.3.2).

con = file("pathtotargetfile", "r")
readsizeof<-2    # read size for one step to caculate number of lines in file
nooflines<-0     # number of lines
while((linesread<-length(readLines(con,readsizeof)))>0)    # calculate number of lines. Also a better solution for big file
  nooflines<-nooflines+linesread

con = file("pathtotargetfile", "r")    # open file again to variable con, since the cursor have went to the end of the file after caculating number of lines
typelist = list(0,'c',0,'c',0,0,'c',0)    # a list to specific the lines data type, which means the first line has same type with 0 (e.g. numeric)and second line has same type with 'c' (e.g. character). This meet my demand.
for(i in 1:nooflines) {
  tmp <- scan(file=con, nlines=1, what=typelist[[i]], quiet=TRUE)
  print(is.vector(tmp))
  print(tmp)
}
close(con)

I used an inner enum in an interface describing a strategy to keep instance control (each strategy is a Singleton) from there.

public interface VectorizeStrategy {

    /**
     * Keep instance control from here.
     * 
     * Concrete classes constructors should be package private.
     */
    enum ConcreteStrategy implements VectorizeStrategy {
        DEFAULT (new VectorizeImpl());

        private final VectorizeStrategy INSTANCE;

        ConcreteStrategy(VectorizeStrategy concreteStrategy) {
            INSTANCE = concreteStrategy;
        }

        @Override
        public VectorImageGridIntersections processImage(MarvinImage img) {
            return INSTANCE.processImage(img);
        }
    }

    /**
     * Should perform edge Detection in order to have lines, that can be vectorized.
     * 
     * @param img An Image suitable for edge detection.
     * 
     * @return the VectorImageGridIntersections representing img's vectors 
     * intersections with the grids.
     */
    VectorImageGridIntersections processImage(MarvinImage img);
}

The fact that the enum implements the strategy is convenient to allow the enum class to act as proxy for its enclosed Instance. which also implements the interface.

it's a sort of strategyEnumProxy :P the clent code looks like this:

VectorizeStrategy.ConcreteStrategy.DEFAULT.processImage(img);

If it didn't implement the interface it'd had been:

VectorizeStrategy.ConcreteStrategy.DEFAULT.getInstance().processImage(img);

It's important to note that the order of parameters is actually important to spring. The BindingResult needs to come right after the Form that is being validated. Likewise, the [optional] Model parameter needs to come after the BindingResult. Example:

Valid:

@RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  final BindingResult bindingResult,
                                  @RequestParam("pk") final long pk,
                                  final Model model) {
}

Not Valid:

RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  @RequestParam("pk") final long pk,
                                  final BindingResult bindingResult,
                                  final Model model) {
}

Django does not support free group by queries. I learned it in the very bad way. ORM is not designed to support stuff like what you want to do, without using custom SQL. You are limited to:

• RAW sql (i.e. MyModel.objects.raw())
• cr.execute sentences (and a hand-made parsing of the result).
• .annotate() (the group by sentences are performed in the child model for .annotate(), in examples like aggregating lines_count=Count('lines'))).

Over a queryset qs you can call qs.query.group_by = ['field1', 'field2', ...] but it is risky if you don't know what query are you editing and have no guarantee that it will work and not break internals of the QuerySet object. Besides, it is an internal (undocumented) API you should not access directly without risking the code not being anymore compatible with future Django versions.

An alias will expand to the string it represents. Anything after the alias will appear after its expansion without needing to be or able to be passed as explicit arguments (e.g. $1).

$ alias foo='/path/to/bar'
$ foo some args

will get expanded to

$ /path/to/bar some args

If you want to use explicit arguments, you'll need to use a function

$ foo () { /path/to/bar "$@" fixed args; }
$ foo abc 123

will be executed as if you had done

$ /path/to/bar abc 123 fixed args

To undefine an alias:

unalias foo

To undefine a function:

unset -f foo

To see the type and definition (for each defined alias, keyword, function, builtin or executable file):

type -a foo

Or type only (for the highest precedence occurrence):

type -t foo

Of course. That is normal and sane behaviour. Instead of closing and re-opening, you could rewind the file.

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

for who one in laravel 5 or greater in blade:

{{ $table->appends(['id' => $something ])->links() }}

you can get the passed item with

$passed_item=$request->id;

test it with

dd($passed_item);

you must get $something value

We can use following code

textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);

Where

• "Text" – the property of textbox
• model – the model object enter code here
• "Name" – the value of model which to bind the textbox.

The jQuery documentation has a link to this article 'Basic usage of the jQuery UI dialog' that explains this situation and how to resolve it.

The inplace parameter:

df.dropna(axis='index', how='all', inplace=True)

in Pandas and in general means:

1. Pandas creates a copy of the original data

2. ... does some computation on it

3. ... assigns the results to the original data.

4. ... deletes the copy.

As you can read in the rest of my answer's further below, we still can have good reason to use this parameter i.e. the inplace operations, but we should avoid it if we can, as it generate more issues, as:

1. Your code will be harder to debug (Actually SettingwithCopyWarning stands for warning you to this possible problem)

2. Conflict with method chaining

So there is even case when we should use it yet?

Definitely yes. If we use pandas or any tool for handeling huge dataset, we can easily face the situation, where some big data can consume our entire memory. To avoid this unwanted effect we can use some technics like method chaining:

(
    wine.rename(columns={"color_intensity": "ci"})
    .assign(color_filter=lambda x: np.where((x.hue > 1) & (x.ci > 7), 1, 0))
    .query("alcohol > 14 and color_filter == 1")
    .sort_values("alcohol", ascending=False)
    .reset_index(drop=True)
    .loc[:, ["alcohol", "ci", "hue"]]
)

which make our code more compact (though harder to interpret and debug too) and consumes less memory as the chained methods works with the other method's returned values, thus resulting in only one copy of the input data. We can see clearly, that we will have 2 x original data memory consumption after this operations.

Or we can use inplace parameter (though harder to interpret and debug too) our memory consumption will be 2 x original data, but our memory consumption after this operation remains 1 x original data, which if somebody whenever worked with huge datasets exactly knows can be a big benefit.

Final conclusion:

Avoid using inplace parameter unless you don't work with huge data and be aware of its possible issues in case of still using of it.

string tail = test.Substring(test.LastIndexOf('-') + 1);

This code works for me:

Sub test()
    Dim myRange As Range
    Dim NumRows As Integer

    Set myRange = Range("A:A")
    NumRows = Application.WorksheetFunction.CountA(myRange)

    MsgBox NumRows
End Sub

you can simply use this:

Map<String, String[]> parameters = request.getParameterMap();

That should work fine

I found this, and it works for me:

/(\^|\~?)(\d|x|\*)+\.(\d|x|\*)+\.(\d|x|\*)+

Go to System Properties > Advanced > Enviroment Variables and look under System variables

First, create/set your JAVA_HOME variable

Even though Eclipse doesn't consult the JAVA_HOME variable, it's still a good idea to set it. See How do I run Eclipse? for more information.

If you have not created and/or do not see JAVA_HOME under the list of System variables, do the following:

1. Click New... at the very bottom
2. For Variable name, type JAVA_HOME exactly
3. For Variable value, this could be different depending on what bits your computer and java are.
   • If both your computer and java are 64-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, type C:\Program Files (x86)\Java\jdk1.8.0_60

If you have created and/or do see JAVA_HOME, do the following:

1. Click on the row under System variables that you see JAVA_HOME in
2. Click Edit... at the very bottom
3. For Variable value, change it to what was stated in #3 above based on java's and your computer's bits. To repeat:
   • If both your computer and java are 64-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, change it to C:\Program Files (x86)\Java\jdk1.8.0_60

Next, add to your PATH variable

1. Click on the row under System variables with PATH in it
2. Click Edit... at the very bottom
3. If you have a newer version of windows:
   • Click New
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60 depending on the bits of your computer and java (see above ^).
   • Press Enter and Click New again.
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre depending on the bits of your computer and java (see above again ^).
   • Press Enter and press OK on all of the related windows
4. If you have an older version of windows
   • In the Variable value textbox (or something similar) drag the cursor all the way to the very end
   • Add a semicolon (;) if there isn't one already
   • C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60
   • Add another semicolon (;)
   • C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre

Changing eclipse.ini

1. Find your eclipse.ini file and copy-paste it in the same directory (should be named eclipse(1).ini)
2. Rename eclipse.ini to eclipse.ini.old just in case something goes wrong
3. Rename eclipse(1).ini to eclipse.ini

4. Open your newly-renamed eclipse.ini and replace all of it with this:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
   -product
   org.eclipse.epp.package.java.product
   --launcher.defaultAction
   openFile
   --launcher.XXMaxPermSize
   256M
   -showsplash
   org.eclipse.platform
   --launcher.XXMaxPermSize
   256m
   --launcher.defaultAction
   openFile
   -vm
   C:\Program Files\Java\jdk1.8.0_60\bin\javaw.exe
   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms40m
   -Xmx1024m
   

XXMaxPermSize may be deprecated, so it might not work. If eclipse still does not launch, do the following:

1. Delete the newer eclipse.ini
2. Rename eclipse.ini.old to eclipse.ini
3. Open command prompt
4. type in eclipse -vm C:\Program Files (x86)\Java\jdk1.8.0_60\bin\javaw.exe

If the problem remains

Try updating your eclipse and java to the latest version. 8u60 (1.8.0_60) is not the latest version of java. Sometimes, the latest version of java doesn't work with older versions of eclipse and vice versa. Otherwise, leave a comment if you're still having problems. You could also try a fresh reinstallation of Java.

HTML

  <div class="fileUpload btn btn-primary">
    <label class="upload">
      <input name='Image' type="file"/>
    Upload Image
    </label>
  </div>

CSS

input[type="file"]
{
  display: none;
}
.fileUpload input.upload 
{
    display: inline-block;
}

Note: Btn btn-primary is a class of bootstrap button. However the button may look weired in position. Hope you can fix it by inline css.

1. Select the <html> tag in Elements.
2. Do CTRL-C.
3. Check if there is only lefting <!DOCTYPE html> before the <html>.

For those with a C++ background, you may be interested in a comparison with the C++ equivalent:

class S
{
private: // this is not quite true, in Ruby you can still access these
  static int    k = 23;
  int           s = 15;

public:
  int get_s() { return s; }
  static int get_k() { return k; }

};

std::cerr << S::k() << "\n";

S instance;
std::cerr << instance.s() << "\n";
std::cerr << instance.k() << "\n";

As we can see, k is a static like variable. This is 100% like a global variable, except that it's owned by the class (scoped to be correct). This makes it easier to avoid clashes between similarly named variables. Like any global variable, there is just one instance of that variable and modifying it is always visible by all.

On the other hand, s is an object specific value. Each object has its own instance of the value. In C++, you must create an instance to have access to that variable. In Ruby, the class definition is itself an instance of the class (in JavaScript, this is called a prototype), therefore you can access s from the class without additional instantiation. The class instance can be modified, but modification of s is going to be specific to each instance (each object of type S). So modifying one will not change the value in another.

I know it's an old thread I worked with above answer and had to add:

header('Access-Control-Allow-Methods: GET, POST, PUT');

So my header looks like:

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');

And the problem was fixed.

if don't work above port id then change it.like 8082,8080 Restart xammp,Start apache server,Check it.It's now working.

I think COALESCE function partially similar to the isnull, but try it.

Why don't you go for null handling functions through application programs, it is better alternative.

Try set-executionpolicy "Policyname" -force switch and the warnings pop-up should not come.

Although @ruakh gave a good answer, I will add some alternatives for completeness:

You could in fact use even var Omega = 'Ω' in JavaScript, but only if your JavaScript code is:

• inside an event attribute, as in onclick="var Omega = '&#937'; alert(Omega)" or
• in a script element inside an XHTML (or XHTML + XML) document served with an XML content type.

In these cases, the code will be first (before getting passed to the JavaScript interpreter) be parsed by an HTML parser so that character references like Ω are recognized. The restrictions make this an impractical approach in most cases.

You can also enter the O character as such, as in var Omega = 'O', but then the character encoding must allow that, the encoding must be properly declared, and you need software that let you enter such characters. This is a clean solution and quite feasible if you use UTF-8 encoding for everything and are prepared to deal with the issues created by it. Source code will be readable, and reading it, you immediately see the character itself, instead of code notations. On the other hand, it may cause surprises if other people start working with your code.

Using the \u notation, as in var Omega = '\u03A9', works independently of character encoding, and it is in practice almost universal. It can however be as such used only up to U+FFFF, i.e. up to \uffff, but most characters that most people ever heard of fall into that area. (If you need “higher” characters, you need to use either surrogate pairs or one of the two approaches above.)

You can also construct a character using the String.fromCharCode() method, passing as a parameter the Unicode number, in decimal as in var Omega = String.fromCharCode(937) or in hexadecimal as in var Omega = String.fromCharCode(0x3A9). This works up to U+FFFF. This approach can be used even when you have the Unicode number in a variable.

As of .net3.5+ instead of using a Dictionary<IKey, List<IValue>> you can use a Lookup from the Linq namespace:

// lookup Order by payment status (1:m) 
// would need something like Dictionary<Boolean, IEnumerable<Order>> orderIdByIsPayed
ILookup<Boolean, Order> byPayment = orderList.ToLookup(o => o.IsPayed);
IEnumerable<Order> payedOrders = byPayment[false];

From msdn:

A Lookup resembles a Dictionary. The difference is that a Dictionary maps keys to single values, whereas a Lookup maps keys to collections of values.

You can create an instance of a Lookup by calling ToLookup on an object that implements IEnumerable.

You may also want to read this answer to a related question. For more info, consult msdn.

Full example:

using System;
using System.Collections.Generic;
using System.Linq;

namespace LinqLookupSpike
{
    class Program
    {
        static void Main(String[] args)
        {
            // init 
            var orderList = new List<Order>();
            orderList.Add(new Order(1, 1, 2010, true));//(orderId, customerId, year, isPayed)
            orderList.Add(new Order(2, 2, 2010, true));
            orderList.Add(new Order(3, 1, 2010, true));
            orderList.Add(new Order(4, 2, 2011, true));
            orderList.Add(new Order(5, 2, 2011, false));
            orderList.Add(new Order(6, 1, 2011, true));
            orderList.Add(new Order(7, 3, 2012, false));

            // lookup Order by its id (1:1, so usual dictionary is ok)
            Dictionary<Int32, Order> orders = orderList.ToDictionary(o => o.OrderId, o => o);

            // lookup Order by customer (1:n) 
            // would need something like Dictionary<Int32, IEnumerable<Order>> orderIdByCustomer
            ILookup<Int32, Order> byCustomerId = orderList.ToLookup(o => o.CustomerId);
            foreach (var customerOrders in byCustomerId)
            {
                Console.WriteLine("Customer {0} ordered:", customerOrders.Key);
                foreach (var order in customerOrders)
                {
                    Console.WriteLine("    Order {0} is payed: {1}", order.OrderId, order.IsPayed);
                }
            }

            // the same using old fashioned Dictionary
            Dictionary<Int32, List<Order>> orderIdByCustomer;
            orderIdByCustomer = byCustomerId.ToDictionary(g => g.Key, g => g.ToList());
            foreach (var customerOrders in orderIdByCustomer)
            {
                Console.WriteLine("Customer {0} ordered:", customerOrders.Key);
                foreach (var order in customerOrders.Value)
                {
                    Console.WriteLine("    Order {0} is payed: {1}", order.OrderId, order.IsPayed);
                }
            }

            // lookup Order by payment status (1:m) 
            // would need something like Dictionary<Boolean, IEnumerable<Order>> orderIdByIsPayed
            ILookup<Boolean, Order> byPayment = orderList.ToLookup(o => o.IsPayed);
            IEnumerable<Order> payedOrders = byPayment[false];
            foreach (var payedOrder in payedOrders)
            {
                Console.WriteLine("Order {0} from Customer {1} is not payed.", payedOrder.OrderId, payedOrder.CustomerId);
            }
        }

        class Order
        {
            // key properties
            public Int32 OrderId { get; private set; }
            public Int32 CustomerId { get; private set; }
            public Int32 Year { get; private set; }
            public Boolean IsPayed { get; private set; }

            // additional properties
            // private List<OrderItem> _items;

            public Order(Int32 orderId, Int32 customerId, Int32 year, Boolean isPayed)
            {
                OrderId = orderId;
                CustomerId = customerId;
                Year = year;
                IsPayed = isPayed;
            }
        }
    }
}

Remark on Immutability

By default, Lookups are kind of immutable and accessing the internals would involve reflection. If you need mutability and don't want to write your own wrapper, you could use MultiValueDictionary (formerly known as MultiDictionary) from corefxlab (formerly part ofMicrosoft.Experimental.Collections which isn't updated anymore).

You could also type 'conda list' in a command line. This will print out the installed modules with the version numbers. The path within your file structure will be printed at the top of this list.

There is a solution provided to this problem in some of the OTN forums (https://kr.forums.oracle.com/forums/thread.jspa?messageID=3699989). But, the root cause of the problem is not explained. Following is my attempt to explain the root cause of the problem.

The Oracle JDBC drivers communicate with the Oracle server in a secure way. The drivers use the java.security.SecureRandom class to gather entropy for securing the communication. This class relies on the native platform support for gathering the entropy.

Entropy is the randomness collected/generated by an operating system or application for use in cryptography or other uses that require random data. This randomness is often collected from hardware sources, either from the hardware noises, audio data, mouse movements or specially provided randomness generators. The kernel gathers the entropy and stores it is an entropy pool and makes the random character data available to the operating system processes or applications through the special files /dev/random and /dev/urandom.

Reading from /dev/random drains the entropy pool with requested amount of bits/bytes, providing a high degree of randomness often desired in cryptographic operations. In case, if the entropy pool is completely drained and sufficient entropy is not available, the read operation on /dev/random blocks until additional entropy is gathered. Due to this, applications reading from /dev/random may block for some random period of time.

In contrast to the above, reading from the /dev/urandom does not block. Reading from /dev/urandom, too, drains the entropy pool but when short of sufficient entropy, it does not block but reuses the bits from the partially read random data. This is said to be susceptible to cryptanalytical attacks. This is a theorotical possibility and hence it is discouraged to read from /dev/urandom to gather randomness in cryptographic operations.

The java.security.SecureRandom class, by default, reads from the /dev/random file and hence sometimes blocks for random period of time. Now, if the read operation does not return for a required amount of time, the Oracle server times out the client (the jdbc drivers, in this case) and drops the communication by closing the socket from its end. The client when tries to resume the communication after returning from the blocking call encounters the IO exception. This problem may occur randomly on any platform, especially, where the entropy is gathered from hardware noises.

As suggested in the OTN forum, the solution to this problem is to override the default behaviour of java.security.SecureRandom class to use the non-blocking read from /dev/urandom instead of the blocking read from /dev/random. This can be done by adding the following system property -Djava.security.egd=file:///dev/urandom to the JVM. Though this is a good solution for the applications like the JDBC drivers, it is discouraged for applications that perform core cryptographic operations like crytographic key generation.

Other solutions could be to use different random seeder implementations available for the platform that do not rely on hardware noises for gathering entropy. With this, you may still require to override the default behaviour of java.security.SecureRandom.

Increasing the socket timeout on the Oracle server side can also be a solution but the side effects should be assessed from the server point of view before attempting this.

Objects will be cleaned up when they are no longer being used and when the garbage collector sees fit. Sometimes, you may need to set an object to null in order to make it go out of scope (such as a static field whose value you no longer need), but overall there is usually no need to set to null.

Regarding disposing objects, I agree with @Andre. If the object is IDisposable it is a good idea to dispose it when you no longer need it, especially if the object uses unmanaged resources. Not disposing unmanaged resources will lead to memory leaks.

You can use the using statement to automatically dispose an object once your program leaves the scope of the using statement.

using (MyIDisposableObject obj = new MyIDisposableObject())
{
    // use the object here
} // the object is disposed here

Which is functionally equivalent to:

MyIDisposableObject obj;
try
{
    obj = new MyIDisposableObject();
}
finally
{
    if (obj != null)
    {
        ((IDisposable)obj).Dispose();
    }
}

Once you have identified the columns that contain blanks, wrap that query in a count. If you actually need to identify the fields for some kind of update, consider selecting the ROWID as well.

Topics are for the publisher-subscriber model, while queues are for point-to-point.

You should probable start ssh-agent and add your keys. Check this,

It helped me.

Regarding this part:

When I convert it to UTF-8 without bom and close file, the file is again ANSI when I reopen.

The easiest solution is to avoid the problem entirely by properly configuring Notepad++.

Try Settings -> Preferences -> New document -> Encoding -> choose UTF-8 without BOM, and check Apply to opened ANSI files.

That way all the opened ANSI files will be treated as UTF-8 without BOM.

For explanation what's going on, read the comments below this answer.

You can see my blog post. You can set custom height of Textblock from codebehind. For setting custom height you need to set it inside in a border or stackpanel

This may be cleaner (you dont need all the into statements):

var query = 
    from order in dc.Orders
    from vendor 
    in dc.Vendors
        .Where(v => v.Id == order.VendorId)
        .DefaultIfEmpty()
    from status 
    in dc.Status
        .Where(s => s.Id == order.StatusId)
        .DefaultIfEmpty()
    select new { Order = order, Vendor = vendor, Status = status } 
    //Vendor and Status properties will be null if the left join is null

Here is another left join example

var results = 
    from expense in expenseDataContext.ExpenseDtos
    where expense.Id == expenseId //some expense id that was passed in
    from category 
    // left join on categories table if exists
    in expenseDataContext.CategoryDtos
                         .Where(c => c.Id == expense.CategoryId)
                         .DefaultIfEmpty() 
    // left join on expense type table if exists
    from expenseType 
    in expenseDataContext.ExpenseTypeDtos
                         .Where(e => e.Id == expense.ExpenseTypeId)
                         .DefaultIfEmpty()
    // left join on currency table if exists
    from currency 
    in expenseDataContext.CurrencyDtos
                         .Where(c => c.CurrencyID == expense.FKCurrencyID)
                         .DefaultIfEmpty() 
    select new 
    { 
        Expense = expense,
        // category will be null if join doesn't exist
        Category = category,
        // expensetype will be null if join doesn't exist
        ExpenseType = expenseType,
        // currency will be null if join doesn't exist
        Currency = currency  
    }

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

To add to the accepted answer:

Bear in mind that set -e sometimes is not enough, specially if you have pipes.

For example, suppose you have this script

#!/bin/bash
set -e 
./configure  > configure.log
make

... which works as expected: an error in configure aborts the execution.

Tomorrow you make a seemingly trivial change:

#!/bin/bash
set -e 
./configure  | tee configure.log
make

... and now it does not work. This is explained here, and a workaround (Bash only) is provided:

#!/bin/bash
set -e 
set -o pipefail

./configure  | tee configure.log
make

Following Makefile code worked:

obj-m = hello.o

all:
    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules 

clean:
    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

1. Create rounded_corner.xml in the drawable folder and add the following content,

   <solid android:color="#ffffff" />
   
   <padding
           android:left="1dp"
           android:right="1dp"
           android:bottom="1dp"
           android:top="1dp" />
   
   <corners android:radius="5dp" />
   

2. Set this drawable in the TextView background property like so:

   android:background="@drawable/rounded_corner"
   

I hope this is useful for you.

another solution , you can add <br> tag to your table

    |Method name| Behavior |
    |--|--|
    | OnAwakeLogicController(); | Its called when MainLogicController is loaded into the memory , its also hold the following actions :- <br> 1. Checking Audio Settings <br>2. Initializing Level Controller|

Here's a simple CSS solution that'll work:

#fix-footer{
    position: fixed;
    left: 0px;
    bottom: 0px;
    height: 35px;
    width: 100%;
    background: #1abc9c;
}
