Programs & Examples On #Projects and solutions

This may sound a bit obvious, but I think it's something that is misunderstood because Visual Studio 2005 only shipped with the web site originally. If your project deals with a website that is fairly limited and doesn't have a lot of logical or physical separation, the website is fine. However if it is truly a web application with different modules where many users add and update data, you are better off with the web application.

The biggest pro of the website model is that anything in the app_code section is dynamically compiled. You can make C# file updates without a full redeploy. However this comes at a great sacrifice. A lot of things happen under the covers that are difficult to control. Namespaces are difficult to control and specific DLL usage goes out the window by default for anything under app_code since everything is dynamically compiled.

The web application model does not have dynamic compilation, but you gain control over the things that I have mentioned.

If you are doing n-tier development, I highly recommend the web application model. If you are doing a limited web site or a quick and dirty implementation, the web site model may have advantages.

I was tryng to rename the folder within the visual studio community 2019 and could not find it.

However, I figured out that while the code is running you can not change the name of the folder.

The answer is:

1. Stop your application from running;
2. Then click on the folder with the right click and the rename name will be there.

You need to set the path to the headers in the project properties so the compiler looks there when trying to find the header file(s). I can't remember the exact location, but look though the Project properties and you should see it.

I solved this problem..

near the debug you see drop down menu with some configuration. Default there was Any CPU. Select x86 and run the program it will work. If x86 not there go to configuration manager and add the x86

How about this page from Microsoft Connect (explaining the DesignData and DesignDataWithDesignTimeCreatableTypes) types. Quoting:

The following describes the two Build Actions for Sample Data files.

Sample data .xaml files must be assigned one of the below Build Actions:

DesignData: Sample data types will be created as faux types. Use this Build Action when the sample data types are not creatable or have read-only properties that you want to defined sample data values for.

DesignDataWithDesignTimeCreatableTypes: Sample data types will be created using the types defined in the sample data file. Use this Build Action when the sample data types are creatable using their default empty constructor.

Not so incredibly exhaustive, but it at least gives a hint. This MSDN walkthrough also gives some ideas. I don't know whether these Build Actions are applicable for non-Silverlight projects also.

First loop

$v = $a[0];
$v = $a[1];
$v = $a[2];
$v = $a[3];

Yes! Current $v = $a[3] position.

Second loop

$a[3] = $v = $a[0], echo $v; // same as $a[3] and $a[0] == 'zero'
$a[3] = $v = $a[1], echo $v; // same as $a[3] and $a[1] == 'one'
$a[3] = $v = $a[2], echo $v; // same as $a[3] and $a[2] == 'two'
$a[3] = $v = $a[3], echo $v; // same as $a[3] and $a[3] == 'two'

because $a[3] is assigned by before processing.

On windows, I use a start.bat file like this:

java -Dhttp.port=9001 -DapplyEvolutions.default=true -cp "./lib/*;" play.core.server.NettyServer "."

The -DapplyEvolutions.default=true tells evolution to automatically apply evolutions without asking for confirmation. Use with caution on production environment, of course...

_{Note: The question is about JavaScript, and this answer is about jQuery, which is wrong. This is an old answer, from times when jQuery was widespread.}

Instead, I recommend understanding scopes and closures in JavaScript.

Old, bad answer

With jQuery you can just do this, no matter where the declaration is:

$my_global_var = 'my value';

And will be available everywhere.

I use it for making quick image galleries, when images are spread in different places, like so:

$gallery = $('img');
$current = 0;

$gallery.each(function(i,v){
    // preload images
    (new Image()).src = v;
});
$('div').eq(0).append('<a style="display:inline-block" class="prev">prev</a> <div id="gallery"></div> <a style="display:inline-block" class="next">next</a>');
$('.next').click(function(){
    $current = ( $current == $gallery.length - 1 ) ? 0 : $current + 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});
$('.prev').click(function(){
    $current = ( $current == 0 ) ? $gallery.length - 1 : $current - 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});

Tip: run this whole code in the console in this page ;-)

An abstract class is a class that can't be instantiated. It's only purpose is for other classes to extend.

Abstract methods are methods in the abstract class (have to be declared abstract) which means the extending concrete class must override them as they have no body.

The main purpose of an abstract class is if you have common code to use in sub classes but the abstract class should not have instances of its own.

You can read more about it here: Abstract Methods and Classes

In addition to @BradB Answer :

That is so true... It's strange that it is the only answer who mention that. When beginners discover enums, they quickly take that as a magic-trick for valid identifier checking for the compiler. And when the code is intended to be use on distributed systems, they cry... some month later. Maintain backward compatibility with enums that contains non static list of values is a real concern, and pain. This is because when you add a value to an existing enum, its type change (despite the name does not).

"Ho, wait, it may look like the same type, right? After all, they’re enums with the same name – and aren’t enums just integers under the hood?" And for these reasons, your compiler will likely not flag the use of one definition of the type itself where it was expecting the other. But in fact, they are (in most important ways) different types. Most importantly, they have different data domains – values that are acceptable given the type. By adding a value, we’ve effectively changed the type of the enum and therefore break backward compatibility.

In conclusion : Use it when you want, but, please, check that the data domain used is a finite, already known, fixed set.

Okay I have got it working, hope this information is useful.

1. First of all I now realize that not only do self-extracting zip start extracting with doubleclick, but they require no extraction application to be installed on the users computer because the extractor code is in the archive itself. This means that you will get a different user experience depending on what you application you use to create the sfx

2. I went with WinRar as follows, this does not require you to create an sfx file, everything can be created via the gui:

   • Select files, right click and select Add to Archive
   • Use Browse.. to create the archive in the folder above
   • Change Archive Format to Zip
   • Enable Create SFX archive
   • Select Advanced tab
   • Select SFX Options
   • Select Setup tab
   • Enter setup.exe into the Run after Extraction field
   • Select Modes tab
   • Enable Unpack to temporary folder
   • Select text and Icon tab
   • Enter a more appropriate title for your task
   • Select OK
   • Select OK

The resultant exe unzips to a temporary folder and then starts the installer

Yes. The same notation that works for non-empty dict/set works for empty ones.

Notice the difference between non-empty dict and set literals:

{1: 'a', 2: 'b', 3: 'c'} -- a number of key-value pairs inside makes a dict
{'aaa', 'bbb', 'ccc'} -- a tuple of values inside makes a set

So:

{} == zero number of key-value pairs == empty dict
{*()} == empty tuple of values == empty set

However the fact, that you can do it, doesn't mean you should. Unless you have some strong reasons, it's better to construct an empty set explicitly, like:

a = set()

Performance:

The literal is ~15% faster than the set-constructor (CPython-3.8, 2019 PC, Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz):

>>> %timeit ({*()} & {*()}) | {*()}
214 ns ± 1.26 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

>>> %timeit (set() & set()) | set()
252 ns ± 0.566 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

... and for completeness, Renato Garcia's frozenset proposal on the above expression is some 60% faster!

>>> ? = frozenset()

>>> %timeit (? & ?) | ?
100 ns ± 0.51 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

NB: As ctrueden noticed in comments, {()} is not an empty set. It's a set with 1 element: empty tuple.

In case, when we have no control over child component, like a 3rd party library component.

We can use *ngIf and setTimeout to reset the child component from parent without making any change in child component.

.template:

.ts:

show:boolean = true

resetChildForm(){
   this.show = false;

   setTimeout(() => {
      this.show = true
    }, 100);
}

This should do it:

[^a-zA-Z0-9]

Basically it matches all non-alphanumeric characters.

With tr:

# Converts upper to lower case 
$ tr '[:upper:]' '[:lower:]' < input.txt > output.txt

# Converts lower to upper case
$ tr '[:lower:]' '[:upper:]' < input.txt > output.txt

Or, sed on GNU (but not BSD or Mac as they don't support \L or \U):

# Converts upper to lower case
$ sed -e 's/\(.*\)/\L\1/' input.txt > output.txt

# Converts lower to upper case
$ sed -e 's/\(.*\)/\U\1/' input.txt > output.txt

If You are using windows then go to python installation path like.

D:\Python37\Scripts>pip install Flask

it take some movement to download the package.

In short, if you have multiple routes defined for your app's routing, enclosed with Switch component like this;

<Switch>

  <Route exact path="/" component={Home} />
  <Route path="/detail" component={Detail} />

  <Route exact path="/functions" component={Functions} />
  <Route path="/functions/:functionName" component={FunctionDetails} />

</Switch>

Then you have to put exact keyword to the Route which it's path is also included by another Route's path. For example home path / is included in all paths so it needs to have exact keyword to differentiate it from other paths which start with /. The reason is also similar to /functions path. If you want to use another route path like /functions-detail or /functions/open-door which includes /functions in it then you need to use exact for the /functions route.

You can use numpy.append() to append a row to numpty array and reshape to a matrix later on.

import numpy as np
a = np.array([1,2])
a = np.append(a, [3,4])
print a
# [1,2,3,4]
# in your example
A = [1,2]
for row in X:
    A = np.append(A, row)

You can also get it by

string(//bookstore/book[1]/title/@lang)    
string(//bookstore/book[2]/title/@lang)

although if you are using XMLDOM with JavaScript you can code something like

var n1 = uXmlDoc.selectSingleNode("//bookstore/book[1]/title/@lang");

and n1.text will give you the value "eng"

You can try like this too.

Your HTML Code

<select id="mySelectionBox">
    <option value="hello">Foo</option>
    <option value="hello1">Foo1</option>
    <option value="hello2">Foo2</option>
    <option value="hello3">Foo3</option>
</select>

You JQuery Code

$("#mySelectionBox option").each(function() {
    alert(this.text + ' ' + this.value);
});

OR

var select =  $('#mySelectionBox')[0];

  for (var i = 0; i < select.length; i++){
    var option = select.options[i];
    alert (option.text + ' ' + option.value);
  }

You want the %c conversion specifier, which just reads a sequence of characters without special handling for whitespace.

Note that you need to fill the buffer with zeroes first, because the %c specifier doesn't write a nul-terminator. You also need to specify the number of characters to read (otherwise it defaults to only 1):

memset(buffer, 0, 200);
sscanf("19 cool kid", "%d %199c", &age, buffer);

There are various Inline elements that can help you, for the simplest formatting options you can use Bold, Italic and Underline:

<TextBlock>
    Sample text with <Bold>bold</Bold>, <Italic>italic</Italic> and <Underline>underlined</Underline> words.
</TextBlock>

I think it is worth noting, that those elements are in fact just shorthands for Span elements with various properties set (i.e.: for Bold, the FontWeight property is set to FontWeights.Bold).

This brings us to our next option: the aforementioned Span element.

You can achieve the same effects with this element as above, but you are granted even more possibilities; you can set (among others) the Foreground or the Background properties:

<TextBlock>
    Sample text with <Span FontWeight="Bold">bold</Span>, <Span FontStyle="Italic">italic</Span> and <Span TextDecorations="Underline">underlined</Span> words. <Span Foreground="Blue">Coloring</Span> <Span Foreground="Red">is</Span> <Span Background="Cyan">also</Span> <Span Foreground="Silver">possible</Span>.
</TextBlock>

The Span element may also contain other elements like this:

<TextBlock>
    <Span FontStyle="Italic">Italic <Span Background="Yellow">text</Span> with some <Span Foreground="Blue">coloring</Span>.</Span>
</TextBlock>

There is another element, which is quite similar to Span, it is called Run. The Run cannot contain other inline elements while the Span can, but you can easily bind a variable to the Run's Text property:

<TextBlock>
    Username: <Run FontWeight="Bold" Text="{Binding UserName}"/>
</TextBlock>

Also, you can do the whole formatting from code-behind if you prefer:

TextBlock tb = new TextBlock();
tb.Inlines.Add("Sample text with ");
tb.Inlines.Add(new Run("bold") { FontWeight = FontWeights.Bold });
tb.Inlines.Add(", ");
tb.Inlines.Add(new Run("italic ") { FontStyle = FontStyles.Italic });
tb.Inlines.Add("and ");
tb.Inlines.Add(new Run("underlined") { TextDecorations = TextDecorations.Underline });
tb.Inlines.Add("words.");

Here is a solution handling all Unicode code points include upper (4 byte) values and supported by all modern browsers (IE and others > 5.5). It uses decodeURIComponent(), but NOT the deprecated escape/unescape functions:

function utf8_to_str(a) {
    for(var i=0, s=''; i<a.length; i++) {
        var h = a[i].toString(16)
        if(h.length < 2) h = '0' + h
        s += '%' + h
    }
    return decodeURIComponent(s)
}

Tested and available on GitHub

To create UTF-8 from a string:

function utf8_from_str(s) {
    for(var i=0, enc = encodeURIComponent(s), a = []; i < enc.length;) {
        if(enc[i] === '%') {
            a.push(parseInt(enc.substr(i+1, 2), 16))
            i += 3
        } else {
            a.push(enc.charCodeAt(i++))
        }
    }
    return a
}

Tested and available on GitHub

used the following snippet and it worked fine..

.smallText .bmv-disclaimer {
   height: 40px;
}

do a AutoResetEvent, call the function then wait on AutoResetEvent and then set it inside async void when you know it is done.

You can also wait on a Task that returns from your void async

This modification of a_horse_with_no_name's answer will give you the blocking queries in addition to just the blocked sessions:

SELECT
    activity.pid,
    activity.usename,
    activity.query,
    blocking.pid AS blocking_id,
    blocking.query AS blocking_query
FROM pg_stat_activity AS activity
JOIN pg_stat_activity AS blocking ON blocking.pid = ANY(pg_blocking_pids(activity.pid));

Stack Smashing here is actually caused due to a protection mechanism used by gcc to detect buffer overflow errors. For example in the following snippet:

#include <stdio.h>

void func()
{
    char array[10];
    gets(array);
}

int main(int argc, char **argv)
{
    func();
}

The compiler, (in this case gcc) adds protection variables (called canaries) which have known values. An input string of size greater than 10 causes corruption of this variable resulting in SIGABRT to terminate the program.

To get some insight, you can try disabling this protection of gcc using option -fno-stack-protector while compiling. In that case you will get a different error, most likely a segmentation fault as you are trying to access an illegal memory location. Note that -fstack-protector should always be turned on for release builds as it is a security feature.

You can get some information about the point of overflow by running the program with a debugger. Valgrind doesn't work well with stack-related errors, but like a debugger, it may help you pin-point the location and reason for the crash.

I just ran across this in my RSS Reader today. I've got a cleaner solution for you. This example is in Delphi, but can very easily be converted to C/C++ (It's all Win32).

Query all value names from the following registry location: HKLM\SYSTEM\MountedDevices

One by one, pass them into the following function and you will be returned the device name. Pretty clean and simple! I found this code on a blog here.

function VolumeNameToDeviceName(const VolName: String): String;
var
  s: String;
  TargetPath: Array[0..MAX_PATH] of WideChar;
  bSucceeded: Boolean;
begin
  Result := ”;
  // VolumeName has a format like this: \\?\Volume{c4ee0265-bada-11dd-9cd5-806e6f6e6963}\
  // We need to strip this to Volume{c4ee0265-bada-11dd-9cd5-806e6f6e6963}
  s :=  Copy(VolName, 5, Length(VolName) - 5);

  bSucceeded := QueryDosDeviceW(PWideChar(WideString(s)), TargetPath, MAX_PATH) <> 0;
  if bSucceeded then
  begin
    Result := TargetPath;
  end
  else begin
    // raise exception
  end;

end;

Personally, I tend to think of Matlab as an interactive matrix calculator and plotting tool with a few scripting capabilities, rather than as a full-fledged programming language like Python or C. The reason for its success is that matrix stuff and plotting work out of the box, and you can do a few very specific things in it with virtually no actual programming knowledge. The language is, as you point out, extremely frustrating to use for more general-purpose tasks, such as even the simplest string processing. Its syntax is quirky, and it wasn't created with the abstractions necessary for projects of more than 100 lines or so in mind.

I think the reason why people try to use Matlab as a serious programming language is that most engineers (there are exceptions; my degree is in biomedical engineering and I like programming) are horrible programmers and hate to program. They're taught Matlab in college mostly for the matrix math, and they learn some rudimentary programming as part of learning Matlab, and just assume that Matlab is good enough. I can't think of anyone I know who knows any language besides Matlab, but still uses Matlab for anything other than a few pure number crunching applications.

 select convert_tz(now(),@@session.time_zone,'+05:30')

replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994

to format into desired time format, eg:

 select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p') 

you will get similar to this -> Dec 17 2014 10:39:56 AM

Removed original answer because it was wrong.

The width is ok- but the height resets to 0

so

 min-height: 400px;

StringUtils's removeStart and removeEnd method help to remove string from start and end of a string.

In this case we could also use combination of this two method

String string = "[wdsd34svdf]";
System.out.println(StringUtils.removeStart(StringUtils.removeEnd(string, "]"), "["));

You can create a hidden textbox with a value of 0. Put the onLoad() code in a if block that checks to make sure the hidden text box value is 0. if it is execute the code and set the textbox value to 1.

Only Double and Float type support POSITIVE_INFINITY constant.

Preface

This answer uses the dynamic routing approach embraced in react-router v4+. Other answers may reference the previously-used "static routing" approach that has been abandoned by react-router.

Solution

react-router is a great solution. You create your pages as Components and the router swaps out the pages according to the current URL. In other words, it replaces your original page with your new page dynamically instead of asking the server for a new page.

For web apps I recommend you read these two things first:

• Full Tutorial
• The react-router docs; it will help you get a better understanding of how Router works.

Summary of the general approach:

1 - Add react-router-dom to your project:

Yarn

yarn add react-router-dom

or NPM

npm install react-router-dom

2 - Update your index.js file to something like:

import { BrowserRouter } from 'react-router-dom';

ReactDOM.render((
  <BrowserRouter>
    <App /> {/* The various pages will be displayed by the `Main` component. */}
  </BrowserRouter>
  ), document.getElementById('root')
);

3 - Create a Main component that will show your pages according to the current URL:

import React from 'react';
import { Switch, Route } from 'react-router-dom';

import Home from '../pages/Home';
import Signup from '../pages/Signup';

const Main = () => {
  return (
    <Switch> {/* The Switch decides which component to show based on the current URL.*/}
      <Route exact path='/' component={Home}></Route>
      <Route exact path='/signup' component={Signup}></Route>
    </Switch>
  );
}

export default Main;

4 - Add the Main component inside of the App.js file:

function App() {
  return (
    <div className="App">
      <Navbar />
      <Main />
    </div>
  );
}

5 - Add Links to your pages.

(You must use Link from react-router-dom instead of just a plain old <a> in order for the router to work properly.)

import { Link } from "react-router-dom";
...
<Link to="/signup">
  <button variant="outlined">
    Sign up
  </button>
</Link>

I used this method to load a script file dynamically (inside a controller).

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "https://maps.googleapis.com/maps/api/js";
document.body.appendChild(script);

As others have pointed out setInterval and setTimeout will do the trick. I wanted to highlight a bit more advanced technique that I learned from this excellent video by Paul Irish: http://paulirish.com/2010/10-things-i-learned-from-the-jquery-source/

For periodic tasks that might end up taking longer than the repeat interval (like an HTTP request on a slow connection) it's best not to use setInterval(). If the first request hasn't completed and you start another one, you could end up in a situation where you have multiple requests that consume shared resources and starve each other. You can avoid this problem by waiting to schedule the next request until the last one has completed:

// Use a named immediately-invoked function expression.
(function worker() {
  $.get('ajax/test.html', function(data) {
    // Now that we've completed the request schedule the next one.
    $('.result').html(data);
    setTimeout(worker, 5000);
  });
})();

For simplicity I used the success callback for scheduling. The down side of this is one failed request will stop updates. To avoid this you could use the complete callback instead:

(function worker() {
  $.ajax({
    url: 'ajax/test.html', 
    success: function(data) {
      $('.result').html(data);
    },
    complete: function() {
      // Schedule the next request when the current one's complete
      setTimeout(worker, 5000);
    }
  });
})();

Using lodash:

function createRandomString(length) {_x000D_
        var chars = "abcdefghijklmnopqrstufwxyzABCDEFGHIJKLMNOPQRSTUFWXYZ1234567890"_x000D_
        var pwd = _.sampleSize(chars, length || 12)  // lodash v4: use _.sampleSize_x000D_
        return pwd.join("")_x000D_
    }_x000D_
document.write(createRandomString(8))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

The accepted answer didn't actually tell how to get the location, so here is a little more detail. You pass in an int array of length 2 and the values are replaced with the view's (x, y) coordinates (of the top, left corner).

int[] location = new int[2];
myView.getLocationOnScreen(location);
int x = location[0];
int y = location[1];

Notes

• Replacing getLocationOnScreen with getLocationInWindow should give the same results in most cases (see this answer). However, if you are in a smaller window like a Dialog or custom keyboard, then use you will need to choose which one better suits your needs.
• You will get (0,0) if you call this method in onCreate because the view has not been laid out yet. You can use a ViewTreeObserver to listen for when the layout is done and you can get the measured coordinates. (See this answer.)

Not sure about how other people solve this problem or whether Bootstrap has any configuration for this.

I found this thread that provides a solution:

https://github.com/twbs/bootstrap/issues/1411

One of the post suggests the use of

<ul class="dropdown-menu" style="right: 0; left: auto;">

I tested and it works.

Hope to know whether Bootstrap provides config for doing this, not via the above css.

Cheers.

Just noting a different way of questionable usefulness, using os.environ:

import os
python_executable_path = os.environ['_']

e.g.

$ python -c "import os; print(os.environ['_'])"
/usr/bin/python

This should work for you.

In .html:

<div class="my_class" (click)="clickEvent()"  
    [ngClass]="status ? 'success' : 'danger'">                
     Some content
</div>

In .ts:

status: boolean = false;
clickEvent(){
    this.status = !this.status;       
}

No, because it contains items there must be an instance of it. Its items being null is irrelevant, so the statment ((arrayList) != null) == true

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

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

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

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

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

I wrote about this ages ago after having these same problems myself:

How to delete/revert a Git commit

Basically you just need to do:

git log, get the first seven characters of the SHA hash, and then do a git revert <sha> followed by git push --force.

You can also revert this by using the Git revert command as follows: git revert <sha> -m -1 and then git push.

I think I found convenient approach to handle StaleElementReferenceException. Usually you have to write wrappers for every WebElement method to retry actions, which is frustrating and wastes lots of time.

Adding this code

webDriverWait.until((webDriver1) -> (((JavascriptExecutor) webDriver).executeScript("return document.readyState").equals("complete")));

if ((Boolean) ((JavascriptExecutor) webDriver).executeScript("return window.jQuery != undefined")) {
    webDriverWait.until((webDriver1) -> (((JavascriptExecutor) webDriver).executeScript("return jQuery.active == 0")));
}

before every WebElement action can increase stability of your tests but you still can get StaleElementReferenceException from time to time.

So this is what I came up with (using AspectJ):

package path.to.your.aspects;

    }

    private void waitUntilPageIsLoaded() {

    private static String getBy(WebElement webElement) {

                try {
                    Field foundBy = webElement.getClass().getDeclaredField("foundBy");
                    foundBy.setAccessible(true);
                    return (String) foundBy.get(webElement);
                } catch (NoSuchFieldException e) {
                    e.printStackTrace();
                }
            } else {

            }
        } catch (IllegalAccessException | NoSuchFieldException e) {
            e.printStackTrace();
        }

        return null;
    }
}

To enable this aspect create file src\main\resources\META-INF\aop-ajc.xml and write

<aspectj>
    <aspects>
        <aspect name="path.to.your.aspects.WebElementAspect"/>
    </aspects>
</aspectj>

Add this to your pom.xml

<properties>
    <aspectj.version>1.9.1</aspectj.version>
</properties>

<build>
    <plugins>
        <plugin>

                </argLine>
            </configuration>

                </dependency>
            </dependencies>
        </plugin>
</build>

And thats all. Hope it helps.

Assuming you are using this plugin, you are misusing the .set method. .set must be passed the name of the key as a string as well as the value. I suppose you meant to write:

$.session.set("userName", $("#uname").val());

This sets the userName key in session storage to the value of the input, and allows you to retrieve it using:

$.session.get('userName');

Pointers are similar to normal variables in that you don't need to delete them. They are removed from memory at the end of a functions execution and/or the end of the program.

You can however use pointers to allocate a 'block' of memory, for example like this:

int *some_integers = new int[20000]

This will allocate memory space for 20000 integers. Useful, because the Stack has a limited size and you might want to mess about with a big load of 'ints' without a stack overflow error.

Whenever you call new, you should then 'delete' at the end of your program, because otherwise you will get a memory leak, and some allocated memory space will never be returned for other programs to use. To do this:

delete [] some_integers;

Hope that helps.

I hope you find this helpful.

I couldn't properly follow the other answers, here's more of a dummies guide...

You can do this either way round to go trunk -> branch or branch -> trunk. I always first do trunk -> branch fix any conflicts there and then merge branch -> trunk.

Merge trunk into a branch / tag

1. Checkout the branch / tag
2. Right-click on the root of the branch | Tortoise SVN | Merge ...
3. Merge Type: Merge a range of revisions | Click 'Next'
4. Merge revision range: Select the URL of the trunk directory that you copied to the branch / tag. Enter the revisions to merge or leave the field empty to merge all revisions | click 'Next'
5. Merge options: I just left these as default | click 'Merge'
6. This will merge the revisions into the checked out branch / tag
7. Then commit the merged changes to the branch / tag

you can try this way in Colab

!git clone https://github.com/UKPLab/sentence-transformers.git
!pip install -e /content/sentence-transformers
import sentence_transformers

This setting goes in your web.config file. It affects the entire application, though... I don't think you can set it per page.

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="xxx" />
  </system.web>
</configuration>

"xxx" is in KB. The default is 4096 (= 4 MB).

Your workaround actually just saved me. I was having a lot of problems processing the request using the Falcon framework. This worked for me. req being the request form curl pr httpie

json.loads(req.stream.read().decode('utf-8'))

In Sender Activity Side:

Intent passIntent = new Intent(getApplicationContext(), "ActivityName".class);
passIntent.putExtra("value", integerValue);
startActivity(passIntent);

In Receiver Activity Side:

int receiveValue = getIntent().getIntExtra("value", 0);

I had the same issue and i manage to fix it by disabling my AVAST Anti Virus. As well as my AVAST extension in the browser. Antivirus sometimes blocks your application. :) I hope it helps to anyone.

You should use Task.Delay instead of Sleep for async programming and then use Task.WhenAll to combine the task results. The tasks would run in parallel.

public class Program
    {
        static void Main(string[] args)
        {
            Go();
        }
        public static void Go()
        {
            GoAsync();
            Console.ReadLine();
        }
        public static async void GoAsync()
        {

            Console.WriteLine("Starting");

            var task1 = Sleep(5000);
            var task2 = Sleep(3000);

            int[] result = await Task.WhenAll(task1, task2);

            Console.WriteLine("Slept for a total of " + result.Sum() + " ms");

        }

        private async static Task<int> Sleep(int ms)
        {
            Console.WriteLine("Sleeping for {0} at {1}", ms, Environment.TickCount);
            await Task.Delay(ms);
            Console.WriteLine("Sleeping for {0} finished at {1}", ms, Environment.TickCount);
            return ms;
        }
    }

Complementing @Bob Jarvis and @dmikam answer, Postgres don't perform a good plan when you don't use LATERAL, below a simulation, in both cases the query data results are the same, but the cost are very different

Table structure

CREATE TABLE ITEMS (
    N INTEGER NOT NULL,
    S TEXT NOT NULL
);

INSERT INTO ITEMS
  SELECT
    (random()*1000000)::integer AS n,
    md5(random()::text) AS s
  FROM
    generate_series(1,1000000);

CREATE INDEX N_INDEX ON ITEMS(N);

Performing JOIN with GROUP BY in subquery without LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    GROUP BY N
) I2 ON I2.N = I.N
WHERE I.N IN (243477, 997947);

The results

Merge Join  (cost=0.87..637500.40 rows=23 width=37)
  Merge Cond: (i.n = items.n)
  ->  Index Scan using n_index on items i  (cost=0.43..101.28 rows=23 width=37)
        Index Cond: (n = ANY ('{243477,997947}'::integer[]))
  ->  GroupAggregate  (cost=0.43..626631.11 rows=861418 width=12)
        Group Key: items.n
        ->  Index Only Scan using n_index on items  (cost=0.43..593016.93 rows=10000000 width=4)

Using LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN LATERAL (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    WHERE N = I.N
    GROUP BY N
) I2 ON 1=1 --I2.N = I.N
WHERE I.N IN (243477, 997947);

Results

Nested Loop  (cost=9.49..1319.97 rows=276 width=37)
  ->  Bitmap Heap Scan on items i  (cost=9.06..100.20 rows=23 width=37)
        Recheck Cond: (n = ANY ('{243477,997947}'::integer[]))
        ->  Bitmap Index Scan on n_index  (cost=0.00..9.05 rows=23 width=0)
              Index Cond: (n = ANY ('{243477,997947}'::integer[]))
  ->  GroupAggregate  (cost=0.43..52.79 rows=12 width=12)
        Group Key: items.n
        ->  Index Only Scan using n_index on items  (cost=0.43..52.64 rows=12 width=4)
              Index Cond: (n = i.n)

My Postgres version is PostgreSQL 10.3 (Debian 10.3-1.pgdg90+1)

Generally, people prefer indenting with space. It's more consistent across editors, resulting in fewer mismatches of this sort. However, you are allowed to indent with tab. It's your choice; however, you should be aware that the standard of 8 spaces per tab is a bit wide.

Concerning your issue, most probably, your editor messed up. To convert tab to space is really editor-dependent.

On Emacs, for example, you can call the method 'untabify'.

On command line, you can use a sed line (adapt the number of spaces to whatever pleases you):

   sed -e 's;\t;       ;' < yourFile.py > yourNedFile.py

Not sure if this was posted before but I got this working with WebClient. i read the documentation for the WebClient. A key point they make is

If the BaseAddress property is not an empty string ("") and address does not contain an absolute URI, address must be a relative URI that is combined with BaseAddress to form the absolute URI of the requested data. If the QueryString property is not an empty string, it is appended to address.

So all I did was wc.QueryString.Add("source", generatedImage) to add the different query parameters and somehow it matches the property name with the image I uploaded. Hope it helps

    public void postImageToFacebook(string generatedImage, string fbGraphUrl)
    {
        WebClient wc = new WebClient();
        byte[] bytes = System.IO.File.ReadAllBytes(generatedImage);

        wc.QueryString.Add("source", generatedImage);
        wc.QueryString.Add("message", "helloworld");

        wc.UploadFile(fbGraphUrl, generatedImage);

        wc.Dispose();

    }

Use this class in your layout :

public class ActionEditText extends EditText
{
    public ActionEditText(Context context)
    {
        super(context);
    }

    public ActionEditText(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public ActionEditText(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
    }

    @Override
    public InputConnection onCreateInputConnection(EditorInfo outAttrs)
    {
        InputConnection conn = super.onCreateInputConnection(outAttrs);
        outAttrs.imeOptions &= ~EditorInfo.IME_FLAG_NO_ENTER_ACTION;
        return conn;
    }

}

In xml:

<com.test.custom.ActionEditText
                android:id="@+id/postED"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:background="@android:color/transparent"
                android:gravity="top|left"
                android:hint="@string/msg_type_message_here"
                android:imeOptions="actionSend"
                android:inputType="textMultiLine"
                android:maxLines="5"
                android:padding="5dip"
                android:scrollbarAlwaysDrawVerticalTrack="true"
                android:textColor="@color/white"
                android:textSize="20sp" />

I would highly recommend reading Apple's guides, and viewing the WWDC resources listed here: Internationalization and Localization Topics

To specifically answer your question, when you add a new language to your project, you get an opportunity to choose what InfoPlist files to include (if you have multiple targets, you'll have multiple Info plist files). All you need to do to get the following screen is hit the + under Localizations and choose a new language to add support for.

Once you've added, it will create the necessary string files in the appropriate lproj directories for the given language.

--EDIT--

Just to be clear, iOS will swap out the string for your Plist file based upon the user's currently selected language using the plist entry's key as the key in the localized strings file.

This error generally occurs when the angular project was not configure completely.

This will work

npm install --save-dev @angular-devkit/build-angular

npm install

You can use GNU date command as shown below

Getting Date In the Past

To get yesterday and earlier day in the past use string day ago:

date --date='yesterday'

date --date='1 day ago'

date --date='10 day ago'

date --date='10 week ago'

date --date='10 month ago'

date --date='10 year ago'

Getting Date In the Future

To get tomorrow and day after tomorrow (tomorrow+N) use day word to get date in the future as follows:

date --date='tomorrow'

date --date='1 day'

date --date='10 day'

date --date='10 week'

date --date='10 month'

date --date='10 year'

git pull wants you to either remove or save your current work so that the merge it triggers doesn't cause conflicts with your uncommitted work. Note that you should only need to remove/save untracked files if the changes you're pulling create files in the same locations as your local uncommitted files.

Remove your uncommitted changes

Tracked files

git checkout -f

Untracked files

git clean -fd

Save your changes for later

Tracked files

git stash

Tracked files and untracked files

git stash -u

Reapply your latest stash after git pull:

git stash pop

MacOS Sierra users can find their auto-generated vanity URL by going to System Preferences > Sharing and checking beneath the Computer Name text input. To access it, enter this URL, plus your port number (e.g. your-name.local:8000), on your iPhone over the same Wi-Fi connection as your computer.

You need to set the password for root@localhost to be blank. There are two ways:

• The MySQL SET PASSWORD command:

  SET PASSWORD FOR root@localhost=PASSWORD('');
  

• Using the command-line mysqladmin tool:

  mysqladmin -u root -pCURRENTPASSWORD password ''
  

I didn't realise from your original question that you were opening a file on the local machine, I thought you were sending a file from the web server to the client.

Based on your screenshot, try formatting your link like so:

<a href="file:///C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">Klik hier</a>

(without knowing the contents of each of your recordset variables I can't give you the exact ASP code)

Did you try format?

@font-face {
  font-family: 'The name of the Font Family Here';
  src: URL('font.ttf') format('truetype');
}

Read this article: http://css-tricks.com/snippets/css/using-font-face/

Also, might depend on browser as well.

android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Because Submit button is inside login_modal so you need to use loginDialog view to access button:

Submit = (Button)loginDialog.findViewById(R.id.Submit);

Since your content-type is application/x-www-form-urlencoded you'll need to encode the POST body, especially if it contains characters like & which have special meaning in a form.

Try passing your string through HttpUtility.UrlEncode before writing it to the request stream.

Here are a couple links for reference.

• http://en.wikipedia.org/wiki/Percent-encoding

Here are the docs about the "new" format syntax. An example would be:

"({:d} goals, ${:d})".format(self.goals, self.penalties)

If both goals and penalties are integers (i.e. their default format is ok), it could be shortened to:

"({} goals, ${})".format(self.goals, self.penalties)

And since the parameters are fields of self, there's also a way of doing it using a single argument twice (as @Burhan Khalid noted in the comments):

"({0.goals} goals, ${0.penalties})".format(self)

Explaining:

• {} means just the next positional argument, with default format;
• {0} means the argument with index 0, with default format;
• {:d} is the next positional argument, with decimal integer format;
• {0:d} is the argument with index 0, with decimal integer format.

There are many others things you can do when selecting an argument (using named arguments instead of positional ones, accessing fields, etc) and many format options as well (padding the number, using thousands separators, showing sign or not, etc). Some other examples:

"({goals} goals, ${penalties})".format(goals=2, penalties=4)
"({goals} goals, ${penalties})".format(**self.__dict__)

"first goal: {0.goal_list[0]}".format(self)
"second goal: {.goal_list[1]}".format(self)

"conversion rate: {:.2f}".format(self.goals / self.shots) # '0.20'
"conversion rate: {:.2%}".format(self.goals / self.shots) # '20.45%'
"conversion rate: {:.0%}".format(self.goals / self.shots) # '20%'

"self: {!s}".format(self) # 'Player: Bob'
"self: {!r}".format(self) # '<__main__.Player instance at 0x00BF7260>'

"games: {:>3}".format(player1.games)  # 'games: 123'
"games: {:>3}".format(player2.games)  # 'games:   4'
"games: {:0>3}".format(player2.games) # 'games: 004'

Note: As others pointed out, the new format does not supersede the former, both are available both in Python 3 and the newer versions of Python 2 as well. Some may say it's a matter of preference, but IMHO the newer is much more expressive than the older, and should be used whenever writing new code (unless it's targeting older environments, of course).

VSQL++ for Oracle is a simplify database management for oracle.

Looks like the DATEFIRST settings is the only way, but it's not possible to make a SET statement in a scalar/table valued function. Therefore, it becomes very error-prone to the colleagues following your code. (become a trap to the others)

In fact, SQL server datepart function should be improved to accept this as parameter instead.

At the meantime, it looks like using the English Name of the week is the safest choice.

this should work also with different predicate

myFunction(strings.find( _ == mystring ).isDefined)

This problem becomes apparent when you try to host a react app in github pages.

How I fixed this,

In in my main application file, called app.tsx, where I include the router. I set the basename, eg, <BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">

Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.

That is all I needed to do.

See working example hosted on GitHub pages at

https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/

i use (and recommend):

$(document).attr("title", "Another Title");

and it works in IE as well this is an alias to

document.title = "Another Title";

Some will debate on wich is better, prop or attr, and since prop call DOM properties and attr Call HTML properties, i think this is actually better...

use this after the DOM Load

$(function(){
    $(document).attr("title", "Another Title");
});

hope this helps.

Define the path of the Visual Studio in your ~/.bash_profile as follow

export PATH="$PATH:/Applications/Visual Studio Code.app/Contents/Resources/app/bin"

You can use {} arround your variable, to separate it from what's after:

echo "{$test}y"

As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.

This works for me, hacked it once to see if it is possible, but never actually used in my program (GUI is so much nicer):

import time
f = '%4i %%'
len_to_clear = len(f)+1
clear = '\x08'* len_to_clear
print 'Progress in percent:'+' '*(len_to_clear),
for i in range(123):
    print clear+f % (i*100//123),
    time.sleep(0.4)
raw_input('\nDone')

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

This is more of an IDE feature than a language feature. Netbeans allows you to define your own folding definitions using the following definition:

// <editor-fold defaultstate="collapsed" desc="user-description">
  ...any code...
// </editor-fold>

As noted in the article, this may be supported by other editors too, but there are no guarantees.

Use the keyword size instead of fontsize.

We had a similar issue and we managed to fix it by setting the Platform target to x86.

For reference : Why does angularjs include an empty option in select?

The empty option is generated when a value referenced by ng-model doesn't exist in a set of options passed to ng-options. This happens to prevent accidental model selection: AngularJS can see that the initial model is either undefined or not in the set of options and don't want to decide model value on its own.

In short: the empty option means that no valid model is selected (by valid I mean: from the set of options). You need to select a valid model value to get rid of this empty option.

Change your code like this

var MyApp=angular.module('MyApp1',[])
MyApp.controller('MyController', function($scope) {
  $scope.feed = {};

  //Configuration
  $scope.feed.configs = [
    {'name': 'Config 1',
     'value': 'config1'},
    {'name': 'Config 2',
     'value': 'config2'},
    {'name': 'Config 3',
     'value': 'config3'}
  ];
  //Setting first option as selected in configuration select
  $scope.feed.config = $scope.feed.configs[0].value;
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div ng-app="MyApp1">
  <div ng-controller="MyController">
    <input type="text" ng-model="feed.name" placeholder="Name" />
    <!-- <select ng-model="feed.config">
<option ng-repeat="template in configs">{{template.name}}</option>
</select> -->
    <select ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
    </select>
  </div>
</div>

Working JSFiddle Demo

UPDATE (Dec 31, 2015)

If You don't want to set a default value and want to remove blank option,

<select ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
      <option value="" selected="selected">Choose</option>
</select>

And in JS no need to initialize value.

$scope.feed.config = $scope.feed.configs[0].value;

Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.

1. Download and install node runtime from http://nodejs.org/download/
2. Install weinre: sudo npm -g install weinre
3. Find out your current IP address at Settings > Network
4. Setup a weinre server on your machine: weinre --boundHost YOUR.IP.ADDRESS.HERE
5. In your browser call: http://YOUR.IP.ADRESS.HERE:8080
6. You'll see a script snippet, place it into your site: <script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
7. Open the debug client in your local browser: http://YOUR.IP.ADDRESS.HERE:8080/client
8. Finally on your Android: call the site you want to inspect (the one with the script inside) and see how it appears as "Target" in your local browser. Now you can open "Elements" or whatever you want.

Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE.

And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.

Happy debugging

P.S. I'm still overwhelmed how good that works. Even elements-highlighting work

Another Java 8 Stream solution to delete all the content of a folder, sub directories included, but not the folder itself.

Usage:

Path folder = Paths.get("/tmp/folder");
CleanFolder.clean(folder);

and the code:

public interface CleanFolder {
    static void clean(Path folder) throws IOException {

        Function<Path, Stream<Path>> walk = p -> {
            try { return Files.walk(p);
        } catch (IOException e) {
            return Stream.empty();
        }};

        Consumer<Path> delete = p -> {
            try {
                Files.delete(p);
            } catch (IOException e) {
            }
        };

        Files.list(folder)
            .flatMap(walk)
            .sorted(Comparator.reverseOrder())
            .forEach(delete);
    }
}

The problem with every stream solution involving Files.walk or Files.delete is that these methods throws IOException which are a pain to handle in streams.

I tried to create a solution which is more concise as possible.

document.getElementById('first').addEventListener('touchstart',myFunction);_x000D_
_x000D_
document.getElementById('first').addEventListener('click',myFunction);_x000D_
    _x000D_
function myFunction(e){_x000D_
  e.preventDefault();e.stopPropagation()_x000D_
  do_something();_x000D_
}    

You should be using e.stopPropagation() because if not, your function will fired twice on mobile

To do this properly is quite complex. For your research, it is known as word tokenization. You should look at NLTK if you want to see what others have done, rather than starting from scratch:

>>> import nltk
>>> paragraph = u"Hi, this is my first sentence. And this is my second."
>>> sentences = nltk.sent_tokenize(paragraph)
>>> for sentence in sentences:
...     nltk.word_tokenize(sentence)
[u'Hi', u',', u'this', u'is', u'my', u'first', u'sentence', u'.']
[u'And', u'this', u'is', u'my', u'second', u'.']

There are plenty of answers here, but I wanted to add something that I commonly use. IF you are in one of the branches that you would like to compare I typically do one of the following. For the sake of this answer we will say that we are in our secondary branch. Depending on what view you need at the time will depend on which you choose, but most of the time I'm using the second option of the two. The first option may be handy if you are trying to revert back to an original copy -- either way, both get the job done!

This will compare master to the branch that we are in (which is secondary) and the original code will be the added lines and the new code will be considered the removed lines

git diff ..master

OR

This will also compare master to the branch that we are in (which is secondary) and the original code will be the old lines and the new code will be the new lines

git diff master..

React 17 delegates events to root instead of document, which might solve the problem. More details here.

I had the problem, I had to replace "Not Available" with NA and my solution goes like this

data <- sapply(data,function(x) {x <- gsub("Not Available",NA,x)})

Fast forward to 2018 and C++17.

• do not use std::string, use std::string_view literals
• please do notice the 'constexpr' bellow. This is also an "compile time" mechanism.
• no inline does not mean repetition
• no cpp files are not necessary for this

• static_assert 'works' at compile time only

  using namespace std::literals;
  
  namespace STANDARD {
  constexpr 
  inline 
  auto 
  compiletime_static_string_view_constant() {
  // make and return string view literal
  // will stay the same for the whole application lifetime
  // will exhibit standard and expected interface
  // will be usable at both
  // runtime and compile time
  // by value semantics implemented for you
      auto when_needed_ =  "compile time"sv;
      return when_needed_  ;
  }
  

  };

Above is a proper and legal standard C++ citizen. It can get readily involved in any and all std:: algorithms, containers, utilities and a such. For example:

// test the resilience
auto return_by_val = []() {
    auto return_by_val = []() {
        auto return_by_val = []() {
            auto return_by_val = []() {
return STANDARD::compiletime_static_string_view_constant();
            };
            return return_by_val();
        };
        return return_by_val();
    };
    return return_by_val();
};

// actually a run time 
_ASSERTE(return_by_val() == "compile time");

// compile time 
static_assert(
   STANDARD::compiletime_static_string_view_constant() 
   == "compile time" 
 );

Enjoy the standard C++

To solve the OP problem without breaking the MVVM, I would use custom value converter and a wrapper for the value (the password) that has to be retrieved from the password box.

public interface IWrappedParameter<T>
{
    T Value { get; }
}

public class PasswordBoxWrapper : IWrappedParameter<string>
{
    private readonly PasswordBox _source;

    public string Value
    {
        get { return _source != null ? _source.Password : string.Empty; }
    }

    public PasswordBoxWrapper(PasswordBox source)
    {
        _source = source;
    }
}

public class PasswordBoxConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // Implement type and value check here...
        return new PasswordBoxWrapper((PasswordBox)value);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new InvalidOperationException("No conversion.");
    }
}

In the view model:

public string Username { get; set; }

public ICommand LoginCommand
{
    get
    {
        return new RelayCommand<IWrappedParameter<string>>(password => { Login(Username, password); });
    }
}

private void Login(string username, string password)
{
    // Perform login here...
}

Because the view model uses IWrappedParameter<T>, it does not need to have any knowledge about PasswordBoxWrapper nor PasswordBoxConverter. This way you can isolate the PasswordBox object from the view model and not break the MVVM pattern.

In the view:

<Window.Resources>
    <h:PasswordBoxConverter x:Key="PwdConverter" />
</Window.Resources>
...
<PasswordBox Name="PwdBox" />
<Button Content="Login" Command="{Binding LoginCommand}"
        CommandParameter="{Binding ElementName=PwdBox, Converter={StaticResource PwdConverter}}" />

For those who don't have nor want to install wget, curl -O (capital "o", not a zero) will do the same thing as wget. E.g. my old netbook doesn't have wget, and is a 2.68 MB install that I don't need.

curl -O https://www.python.org/static/apple-touch-icon-144x144-precomposed.png

Carriage return means to return to the beginning of the current line without advancing downward. The name comes from a printer's carriage, as monitors were rare when the name was coined. This is commonly escaped as \r, abbreviated CR, and has ASCII value 13 or 0x0D.

Linefeed means to advance downward to the next line; however, it has been repurposed and renamed. Used as "newline", it terminates lines (commonly confused with separating lines). This is commonly escaped as \n, abbreviated LF or NL, and has ASCII value 10 or 0x0A. CRLF (but not CRNL) is used for the pair \r\n.

Form feed means advance downward to the next "page". It was commonly used as page separators, but now is also used as section separators. (It's uncommonly used in source code to divide logically independent functions or groups of functions.) Text editors can use this character when you "insert a page break". This is commonly escaped as \f, abbreviated FF, and has ASCII value 12 or 0x0C.

As control characters, they may be interpreted in various ways.

The most common difference (and probably the only one worth worrying about) is lines end with CRLF on Windows, NL on Unix-likes, and CR on older Macs (the situation has changed with OS X to be like Unix). Note the shift in meaning from LF to NL, for the exact same character, gives the differences between Windows and Unix. (Windows is, of course, newer than Unix, so it didn't adopt this semantic shift. I don't know the history of Macs using CR.) Many text editors can read files in any of these three formats and convert between them, but not all utilities can.

Form feed is a bit more interesting (even though less commonly used directly), and with the usual definition of page separator, it can only come between lines (e.g. after the newline sequence of NL, CRLF, or CR) or at the start or end of the file.

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

People have mentioned make but bjam also supports a similar concept. Using bjam -jx instructs bjam to build up to x concurrent commands.

We use the same build scripts on Windows and Linux and using this option halves our build times on both platforms. Nice.

To add Hassou's solution to your .bashrc, try:

alias lst='ls -R | grep ":$" | sed -e '"'"'s/:$//'"'"' -e '"'"'s/[^-][^\/]*\//--/g'"'"' -e '"'"'s/^/   /'"'"' -e '"'"'s/-/|/'"'"

Use 10.0.2.2 for default AVD and 10.0.3.2 for genymotion.

For XSL (on really lazy days) I use:

capture="&(?!amp;)" capturereplace="&"

to translate all &-signs that aren't follwed på amp; to proper ones.

We have cases where the input is in CDATA but the system which uses the XML doesn't take it into account. It's a sloppy fix, beware...

Visual Studio Code: Version 1.14.2 (1.14.2)

1. Press Shift + Command + P to open panel
   • For non-macOS users, press Ctrl+P
2. Enter "settings.json" to open setting files.

3. At default setting, you can see this:

   // Columns at which to show vertical rulers
   "editor.rulers": [],
   

   This means the empty array won't show the vertical rulers.

4. At right window "user setting", add the following:

   "editor.rulers": [140]

Save the file, and you will see the rulers.

Ok. This is an ancient history, but may be my solution could be useful for you or another developers. If I don't want an user press back key in a page (lets say page B called from an page A) and go back to last page (page A), I do next steps:

First, on page A, instead call next page using window.location.href or window.location.replace, I make a call using two commands: window.open and window.close example on page A:

<a href="#"
onclick="window.open('B.htm','B','height=768,width=1024,top=0,left=0,menubar=0,
         toolbar=0,location=0,directories=0,scrollbars=1,status=0');
         window.open('','_parent','');
         window.close();">
      Page B</a>;

All modifiers on window open are just to make up the resulting page. This will open a new window (popWindow) without posibilities of use the back key, and will close the caller page (Page A)

Second: On page B you can use the same proccess if you want this page do the same thing.

Well. This needs the user accept you can open popup windows, but in a controlled system, as if you are programming pages for your work or client, this is easily recommended for the users. Just accept the site as trusted.

Windows SendMessage API with send WM_KEYDOWN.

This is how we do it in our application

def store_location
  session[:return_to] = request.fullpath if request.get? and controller_name != "user_sessions" and controller_name != "sessions"
end

def redirect_back_or_default(default)
  redirect_to(session[:return_to] || default)
end

This way you only store last GET request in :return_to session param, so all forms, even when multiple time POSTed would work with :return_to.

Yet another way is to read the composer.json file, but it can end with wildcard character *

Input => '["3","6","16","120"]'

Type conversion I used => (int)$s;

function Str_Int_Arr($data){
    $h=[];
    $arr=substr($data,1,-1);
    //$exp=str_replace( ",","", $arr);
    $exp=str_replace( "\"","", $arr);
    $s=''; 
    $m=0;
    foreach (str_split($exp) as $k){
        if('0'<= $k && '9'>$k || $k =","){
            if('0' <= $k && '9' > $k){
                $s.=$k;
                $h[$m]=(int)$s;
            }else{
                $s="";
                $m+=1;
            } 
        } 
    } 
    return $h;
}
var_dump(Str_Int_Arr('["3","6","16","120"]'));

Output:

array(4) {
  [0]=>
  int(3)
  [1]=>
  int(6)
  [2]=>
  int(16)
  [3]=>
  int(120)
}

From the documentation:

Paths associated with the default provider are generally interoperable with the java.io.File class. Paths created by other providers are unlikely to be interoperable with the abstract path names represented by java.io.File. The toPath method may be used to obtain a Path from the abstract path name represented by a java.io.File object. The resulting Path can be used to operate on the same file as the java.io.File object. In addition, the toFile method is useful to construct a File from the String representation of a Path.

(emphasis mine)

So, for toFile:

Returns a File object representing this path.

And toPath:

Returns a java.nio.file.Path object constructed from the this abstract path.

Here's a somewhat cleaner way of implementing this. This makes the following changes:

1. The code is DRYed up a bit to remove redundant and repeated code and strings.
2. The code is made more generic/reusable.
3. We make the cache into an object so it has a self-contained interface and there are fewer globals.
4. We compare .src attributes instead of DOM elements to make it work properly.

Code:

function imageCache(base, firstNum, lastNum) {
    this.cache = [];
    var img;
    for (var i = firstNum; i <= lastnum; i++) {
        img = new Image();
        img.src = base + i + ".jpg";
        this.cache.push(img);
    }
}

imageCache.prototype.nextImage(id) {
    var element = document.getElementById(id);
    var targetSrc = element.src;
    var cache = this.cache;
    for (var i = 0; i < cache.length; i++) {
        if (cache[i].src) === targetSrc) {
            i++;
            if (i >= cache.length) {
                i = 0;
            }
            element.src = cache[i].src;
            return;
        }
    }
}

// sample usage

var myCache = new imageCache('images/img/Splash_image', 1, 6);
myCache.nextImage("foo");

Some advantages of this more object oriented and DRYed approach:

1. You can add more images by just creating the images in the numeric sequences and changing one numeric value in the constructor rather than copying lots more lines of array declarations.
2. You can use this more than one place in your app by just creating more than one imageCache object.
3. You can change the base URL by changing one string rather than N strings.
4. The code size is smaller (because of the removal of repeated code).
5. The cache object could easily be extended to offer more capabilities such as first, last, skip, etc...
6. You could add centralize error handling in one place so if one image doesn't exist and doesn't load successfully, it's automatically removed from the cache.
7. You can reuse this in other web pages you develop by only change the arguments to the constructor and not actually changing the implementation code.

P.S. If you don't know what DRY stands for, it's "Don't Repeat Yourself" and basically means that you should never have many copies of similar looking code. Anytime you have that, it should be reduced somehow to a loop or function or something that removes the need for lots of similarly looking copies of code. The end result will be smaller, usually easier to maintain and often more reusable.

Go back to Windows, tell Eclipse to change the encoding to UTF-8, then back to Unix and run d2u on the files.

The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.

<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>

Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.

<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>

When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.

Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>

As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.

<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";

// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);

// Output it month is various formats according to http://php.net/date

echo date('M',$dateAsUnixTimestamp);
// Will output Apr

echo date('n',$dateAsUnixTimestamp);
// Will output 4

echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>

You started with ManyToOne mapping , then you put OneToMany mapping as well for BiDirectional way. Then at OneToMany side (usually your parent table/class), you have to mention "mappedBy" (mapping is done by and in child table/class), so hibernate will not create EXTRA mapping table in DB (like TableName = parent_child).

I just had this problem, it turns it was just because I was using x64 version of the opencv file. Tried the x86 and it worked.

from: http://ruby-doc.org/core/classes/String.html#M000809

str.intern => symbol
str.to_sym => symbol

Returns the Symbol corresponding to str, creating the symbol if it did not previously exist. See Symbol#id2name.

"Koala".intern         #=> :Koala
s = 'cat'.to_sym       #=> :cat
s == :cat              #=> true
s = '@cat'.to_sym      #=> :@cat
s == :@cat             #=> true

This can also be used to create symbols that cannot be represented using the :xxx notation.

'cat and dog'.to_sym   #=> :"cat and dog"

But for your example ...

"Book Author Title".gsub(/\s+/, "_").downcase.to_sym

should go ;)

You could always treat the list like a stack just popping the elements off the top of the stack from the back end of the list. That way you take advantage of first in last out characteristics of a stack. Of course you are consuming the 1st array. I do like this method in that it's pretty intuitive in that you see one list being consumed from the back end while the other is being built from the front end.

>>> l = [1,2,3,4,5,6]; nl=[]
>>> while l:
        nl.append(l.pop())  
>>> print nl
[6, 5, 4, 3, 2, 1]

I have been toying with this as well. I initially had it in my documents folder, but decided that didn't make 'philosophical' sense. I decided to create an Android directory in my home folder and place Eclipse and the Android SKK in there.

I recently ran into this, and it ended up being because I had a convert statement on a null variable. Since that was causing errors, the entire print statement was rendering as null, and not printing at all.

Example - This will fail:

declare @myID int=null
print 'First Statement: ' + convert(varchar(4), @myID)

Example - This will print:

declare @myID int=null
print 'Second Statement: ' +  coalesce(Convert(varchar(4), @myID),'@myID is null')

If you are asking for T-SQL then lets look at fundamentals first. There are three types of joins here each with its own set of logical processing phases as:

1. A cross join is simplest of all. It implements only one logical query processing phase, a Cartesian Product. This phase operates on the two tables provided as inputs to the join and produces a Cartesian product of the two. That is, each row from one input is matched with all rows from the other. So if you have m rows in one table and n rows in the other, you get m×n rows in the result.
2. Then are Inner joins : They apply two logical query processing phases: A Cartesian product between the two input tables as in a cross join, and then it filters rows based on a predicate that you specify in ON clause (also known as Join condition).

3. Next comes the third type of joins, Outer Joins:

   In an outer join, you mark a table as a preserved table by using the keywords LEFT OUTER JOIN, RIGHT OUTER JOIN, or FULL OUTER JOIN between the table names. The OUTER keyword is optional. The LEFT keyword means that the rows of the left table are preserved; the RIGHT keyword means that the rows in the right table are preserved; and the FULL keyword means that the rows in both the left and right tables are preserved.

   The third logical query processing phase of an outer join identifies the rows from the preserved table that did not find matches in the other table based on the ON predicate. This phase adds those rows to the result table produced by the first two phases of the join, and uses NULL marks as placeholders for the attributes from the nonpreserved side of the join in those outer rows.

Now if we look at the question: To return records from the left table which are not found in the right table use Left outer join and filter out the rows with NULL values for the attributes from the right side of the join.

As the thread mentioned in the comment, get-command in powershell can also work it out. For example, you can type get-command npm and the output is as below:

I got this problem when I try to save the file without set the file name.

Old Code

File.WriteAllBytes(@"E:\Folder", Convert.FromBase64String(Base64String));

Working Code

File.WriteAllBytes(@"E:\Folder\"+ fileName, Convert.FromBase64String(Base64String));

Table structure...very basic:

create table tabla(ID int, Stuff varchar (50));

insert into tabla values(1, '32.43');
insert into tabla values(2, '43.33');
insert into tabla values(3, '23.22');

Query:

SELECT SUM(cast(Stuff as decimal(4,2))) as result FROM tabla

Or, try this:

SELECT SUM(cast(isnull(Stuff,0) as decimal(12,2))) as result FROM tabla

Working on SQLServer 2008

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

#function to find mode
def mode(data):  
    modecnt=0
#for count of number appearing
    for i in range(len(data)):
        icount=data.count(data[i])
#for storing count of each number in list will be stored
        if icount>modecnt:
#the loop activates if current count if greater than the previous count 
            mode=data[i]
#here the mode of number is stored 
            modecnt=icount
#count of the appearance of number is stored
    return mode
print mode(data1)

I prefer Scanner because it doesn't throw checked exceptions and therefore it's usage results in a more streamlined code.

1) I tried Broadcast Receiver approach as well even though I know CONNECTIVITY_ACTION/CONNECTIVITY_CHANGE is deprecated in API 28 and not recommended. Also bound to using explicit register, it listens as long as app is running.

2) I also tried Firebase Dispatcher which works but not beyond app killed.

3) Recommended way found is WorkManager to guarantee execution beyond process killed and internally using registerNetworkRequest()

The biggest evidence in favor of #3 approach is referred by Android doc itself. Especially for apps in the background.

Also here

In Android 7.0 we're removing three commonly-used implicit broadcasts — CONNECTIVITY_ACTION, ACTION_NEW_PICTURE, and ACTION_NEW_VIDEO — since those can wake the background processes of multiple apps at once and strain memory and battery. If your app is receiving these, take advantage of the Android 7.0 to migrate to JobScheduler and related APIs instead.

So far it works fine for us using Periodic WorkManager request.

Update: I ended up writing 2 series medium post about it.

use css property style="display:none" or style=visibility:hidden"

I had a similar issue with Angular and IIS throwing a 404 status code on manual refresh and tried the most voted solution but that did not work for me. Also tried a bunch of other solutions having to deal with WebDAV and changing handlers and none worked.

Luckily I found this solution and it worked (took out parts I didn't need). So if none of the above works for you or even before trying them, try this and see if that fixes your angular deployment on iis issue.

Add the snippet to your webconfig in the root directory of your site. From my understanding, it removes the 404 status code from any inheritance (applicationhost.config, machine.config), then creates a 404 status code at the site level and redirects back to the home page as a custom 404 page.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404"/>
      <error statusCode="404" path="/index.html" responseMode="ExecuteURL"/>
    </httpErrors>
  </system.webServer>
</configuration>

This post is a little bit old, but here is another easy solution for getting data related to SMS content provider in Android:

Use this lib: https://github.com/EverythingMe/easy-content-providers

• Get all SMS:

  TelephonyProvider telephonyProvider = new TelephonyProvider(context);
  List<Sms> smses = telephonyProvider.getSms(Filter.ALL).getList();
  

  Each Sms has all fields, so you can get any info you need:
  address, body, receivedDate, type(INBOX, SENT, DRAFT, ..), threadId, ...

• Gel all MMS:

  List<Mms> mmses = telephonyProvider.getMms(Filter.ALL).getList();
  

• Gel all Thread:

  List<Thread> threads = telephonyProvider.getThreads().getList();
  

• Gel all Conversation:

  List<Conversation> conversations = telephonyProvider.getConversations().getList();
  

It works with List or Cursor and there is a sample app to see how it looks and works.

In fact, there is a support for all Android content providers like: Contacts, Call logs, Calendar, ... Full doc with all options: https://github.com/EverythingMe/easy-content-providers/wiki/Android-providers

Hope it also helped :)

You can create a base class in your application that inherits from System.Web.UI.Page. Let all your pages inherit from the newly created base class. Add a property or a variable to your base class with propected access modifier, so that it will be accessed from all your pages in the application.

You can use the package called substring. Just install using the command pip install substring. You can get the substring by just mentioning the start and end characters/indices.

For example:

import substring
s = substring.substringByChar("abcdefghijklmnop", startChar="d", endChar="n")
print(s)

Output:

# s = defghijklmn

Since everything is an expression, and thus results in a value, you can just use if/else.

a = if true then 5 else 10
a = if false then 5 else 10

You can see more about expression examples here.

The code of @ThePracticalOne is great for showing the usage except for one thing: Somtimes the output would be incomplete.(session.recv_ready() turns true after the if session.recv_ready(): while session.recv_stderr_ready() and session.exit_status_ready() turned true before entering next loop)

so my thinking is to retrieving the data when it is ready to exit the session.

while True:
if session.exit_status_ready():
while True:
    while True:
        print "try to recv stdout..."
        ret = session.recv(nbytes)
        if len(ret) == 0:
            break
        stdout_data.append(ret)

    while True:
        print "try to recv stderr..."
        ret = session.recv_stderr(nbytes)
        if len(ret) == 0:
            break
        stderr_data.append(ret)
    break

The Easiest way to implement scrollbar using java swing is as below :

1. Navigate to Design view
2. right click on textArea
3. Select surround with JScrollPane

       var mode = [];
                $("input[name='mode[]']:checked").each(function(i) {
                    mode.push($(this).val());
                })
 if(mode.length == 0)
                {
                   alert('Please select mode!')
                };

i meet this problem, and find this article. http://www.jasonwatmore.com/post/2014/04/18/Post-a-simple-string-value-from-AngularJS-to-NET-Web-API.aspx

The solution I found was to simply wrap the string value in double quotes in your js post

works like a charm! FYI

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

The solution below (class cloning by copying the instance fields and prototype properties) works for me. I am using normal JS (i.e. not Typescript), with JsDoc annotations and VSCode for compile-time type checking.

The solution interface is very simple:

class DerivedBase extends cloneClass(Derived, Base) {}

//To add another superclass:
//class Der1Der2Base extends cloneClass(Derived2, DerivedBase)

let o = new DerivedBase()  

The classes involved can be created just like normal ES6 classes.

However the following needs to be done:

• Use isInstanceOf() instead of the builtin operator instanceof.
• Instead of using 'super' to call non-constructor members of the base class, use the function super2() instead.
• Don't write any code in the constructors, instead write it in a class method called 'init()' that is in turn called by the constructor. See the example below.

/* Tested on latest version of Chrome, Microsoft Edge and FireFox (Win OS)*/

A note of caution: the JSDoc intersection operator & may not always work. In that case some other solution may need to be used. For example, a separate interface class may need to be defined that will 'manually' combine the 2 classes. This interface class can extend from one of the classes and the other class's interface can be automatically implemented using VsCode quick fix option.

Here is another solution using css counter and pseudo elements. I find it more elegant as it doesn't require use of extra html markup nor css classes :

ol,
ul {
    list-style-position: inside;
}

li {
    list-style-type: none;
}

ol {
    counter-reset: ol; //reset the counter for every new ol
}

ul li:before {
        content: '\2022 \00a0 \00a0 \00a0'; //bullet unicode followed by 3 non breakable spaces
}

ol li:before {
        counter-increment: ol;
        content: counter(ol) '.\00a0 \00a0 \00a0'; //css counter followed by a dot and 3 non breakable spaces
}

I use non breakable spaces so that the spacing only affects the first line of my list elements (if the list element is more than one line long). You could use padding here instead.

I resolved the problem.This is for EAServer Windows Service

Resolution is --> Open Regedit in Run prompt

Under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\EAServer

In parameters, give SERVERNAME entry as EAServer.

There is only DateTime type in C# and it consist of both the date and time portion. If you don't care about the Date portion of DateTime, set it to default value like this:

DateTime myTime = default(DateTime).Add(myDateTime.TimeOfDay)

This way you can be consistent across all versions of .NET, even if Microsoft decides to change the base date to something else than 1/1/0001.

Format converts the values to strings. IsDate still returns true because it can parse that string and get a valid date.

If you don't want to change the cells to string, don't use Format. (IOW, don't convert them to strings in the first place.) Use the Cell.NumberFormat, and set it to the date format you want displayed.

ActiveCell.NumberFormat = "mm/dd/yy"   ' Outputs 10/28/13
ActiveCell.NumberFormat = "dd/mm/yyyy" ' Outputs 28/10/2013

I try different solutions but nothing help. But this steps (My GitBash SSH environment always asks for my passphrase, what can I do?) from Bitbucket.com seams works well :

The idea is:

1. you create ~/.bashrc file

2. add follow script:

   SSH_ENV=$HOME/.ssh/environment
   
   # start the ssh-agent
       function start_agent {
       echo "Initializing new SSH agent..."
       # spawn ssh-agent
       /usr/bin/ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
       echo succeeded
       chmod 600 "${SSH_ENV}"
       . "${SSH_ENV}" > /dev/null
       /usr/bin/ssh-add
   }
   
   if [ -f "${SSH_ENV}" ]; then
        . "${SSH_ENV}" > /dev/null
        ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
           start_agent;
       }
   else
       start_agent;
   fi
   

3. re-run Bash

Depending on the language, those might not be considered accents (which change the sound of the letter), but diacritical marks

https://en.wikipedia.org/wiki/Diacritic#Languages_with_letters_containing_diacritics

"Bosnian and Croatian have the symbols c, c, d, š and ž, which are considered separate letters and are listed as such in dictionaries and other contexts in which words are listed according to alphabetical order."

Removing them might be inherently changing the meaning of the word, or changing the letters into completely different ones.

Looks to me as MySQL 3.6 gives the following error while MySQL 3.7 no longer errors out. I am yet to find anything in the documentation regarding this fix.

After reading other solutions, the best solution I can think of, so you run only what you need is the following: You use ngOnChanges to detect the proper change

ngOnChanges() {
  if (changes.messages) {
      let chng = changes.messages;
      let cur  = chng.currentValue;
      let prev = chng.previousValue;
      if(cur && prev) {
        // lazy load case
        if (cur[0].id != prev[0].id) {
          this.lazyLoadHappened = true;
        }
        // new message
        if (cur[cur.length -1].id != prev[prev.length -1].id) {
          this.newMessageHappened = true;
        }
      }
    }

}

And you use ngAfterViewChecked to actually enforce the change before it renders but after the full height is calculated

ngAfterViewChecked(): void {
    if(this.newMessageHappened) {
      this.scrollToBottom();
      this.newMessageHappened = false;
    }
    else if(this.lazyLoadHappened) {
      // keep the same scroll
      this.lazyLoadHappened = false
    }
  }

If you are wondering how to implement scrollToBottom

@ViewChild('scrollWrapper') private scrollWrapper: ElementRef;
scrollToBottom(){
    try {
      this.scrollWrapper.nativeElement.scrollTop = this.scrollWrapper.nativeElement.scrollHeight;
    } catch(err) { }
  }

    [data-value] {
  /* Attribute exists */
}

[data-value="foo"] {
  /* Attribute has this exact value */
}

[data-value*="foo"] {
  /* Attribute value contains this value somewhere in it */
}

[data-value~="foo"] {
  /* Attribute has this value in a space-separated list somewhere */
}

[data-value^="foo"] {
  /* Attribute value starts with this */
}

[data-value|="foo"] {
  /* Attribute value starts with this in a dash-separated list */
}

[data-value$="foo"] {
  /* Attribute value ends with this */
}

Here is the generic solution I use. It solves the problem for importing from modules in the same folder:

import os.path
import sys
sys.path.append(os.path.join(os.path.dirname(__file__), '..'))

Put this at top of the module which gives the error "No module named xxxx"

$string = rtrim($string, ',');

I don't understand why Nick is using margin-left: 200px; instead off floating the other div to the left or right, I've just tweaked his markup, you can use float for both elements instead of using margin-left.

Demo

#main {
    margin: auto;
    width: 400px;
}

#sidebar    {
    width: 100px;
    min-height: 400px;
    background: red;
    float: left;
}

#page-wrap  {
    width: 300px;
    background: #0f0;
    min-height: 400px;
    float: left;
}

.clear:after {
    clear: both;
    display: table;
    content: "";
}

Also, I've used .clear:after which am calling on the parent element, just to self clear the parent.

cursor.execute("INSERT INTO table VALUES (%s, %s, %s)", (var1, var2, var3))

Note that the parameters are passed as a tuple.

The database API does proper escaping and quoting of variables. Be careful not to use the string formatting operator (%), because

1. it does not do any escaping or quoting.
2. it is prone to Uncontrolled string format attacks e.g. SQL injection.

Here is a solution that works in IE, Firefox, and Chrome. The idea is to increase the font size of the br element from the body size of 14px to 18px, and lower the element by 4px so the extra size is below the text line. The result is 4px of extra whitespace below the br.

br 
{ 
font-size: 18px; 
vertical-align: -4px; 
}  

Not sure if this will help in your context...

Can the soap object be cast as a BindingProvider ?

MyWebServiceSoap soap;
MyWebService service = new MyWebService("http://www.google.com");
soap = service.getMyWebServiceSoap();
// set timeouts here
((BindingProvider)soap).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);
    soap.sendRequestToMyWebService();

On the other hand if you are wanting to set the timeout on the initialization of the MyWebService object then this will not help.

This worked for me when wanting to timeout the individual WebService calls.

If multiple resources are specified, either directly or due to the use of a wildcard, then must be a directory, and it must end with a slash /.

Put the below <meta> tag into the <head> section of your document to force the browser to replace unsecure connections (http) to secured connections (https). This can solve the mixed content problem if the connection is able to use https.

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

If you want to block then add the below tag into the <head> tag:

<meta http-equiv="Content-Security-Policy" content="block-all-mixed-content">

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

The proposed solutions are interesting and offer a good reference, however they are only partially satisfying. It is ok to manually add the separator when you have a single specific case or you know the format of the input string, but there can be cases where you want to do it programmatically on generic inputs.

With a bit of experimenting, I believe the criteria is that the path delimiter is not added if the first segment is a drive letter, meaning a single letter followed by a colon, no matter if it corresponds to a real unit.

For example:

import os
testval = ['c:','c:\\','d:','j:','jr:','data:']

for t in testval:
    print ('test value: ',t,', join to "folder"',os.path.join(t,'folder'))

test value:  c: , join to "folder" c:folder
test value:  c:\ , join to "folder" c:\folder
test value:  d: , join to "folder" d:folder
test value:  j: , join to "folder" j:folder
test value:  jr: , join to "folder" jr:\folder
test value:  data: , join to "folder" data:\folder

A convenient way to test for the criteria and apply a path correction can be to use os.path.splitdrive comparing the first returned element to the test value, like t+os.path.sep if os.path.splitdrive(t)[0]==t else t.

Test:

for t in testval:
    corrected = t+os.path.sep if os.path.splitdrive(t)[0]==t else t
    print ('original: %s\tcorrected: %s'%(t,corrected),' join corrected->',os.path.join(corrected,'folder'))

original: c:    corrected: c:\  join corrected-> c:\folder
original: c:\   corrected: c:\  join corrected-> c:\folder
original: d:    corrected: d:\  join corrected-> d:\folder
original: j:    corrected: j:\  join corrected-> j:\folder
original: jr:   corrected: jr:  join corrected-> jr:\folder
original: data: corrected: data:  join corrected-> data:\folder

it can be probably be improved to be more robust for trailing spaces, and I have tested it only on windows, but I hope it gives an idea. See also Os.path : can you explain this behavior? for interesting details on systems other then windows.

Fast-forward almost 9 years since this was first asked, and in the world of .NET Core and .NET Standard, it seems the most common options we have for URL-encoding are WebUtility.UrlEncode (under System.Net) and Uri.EscapeDataString. Judging by the most popular answer here and elsewhere, Uri.EscapeDataString appears to be preferable. But is it? I did some analysis to understand the differences and here's what I came up with:

• WebUtility.UrlEncode encodes space as +; Uri.EscapeDataString encodes it as %20.
• Uri.EscapeDataString percent-encodes !, (, ), and *; WebUtility.UrlEncode does not.
• WebUtility.UrlEncode percent-encodes ~; Uri.EscapeDataString does not.
• Uri.EscapeDataString throws a UriFormatException on strings longer than 65,520 characters; WebUtility.UrlEncode does not. (A more common problem than you might think, particularly when dealing with URL-encoded form data.)
• Uri.EscapeDataString throws a UriFormatException on the high surrogate characters; WebUtility.UrlEncode does not. (That's a UTF-16 thing, probably a lot less common.)

For URL-encoding purposes, characters fit into one of 3 categories: unreserved (legal in a URL); reserved (legal in but has special meaning, so you might want to encode it); and everything else (must always be encoded).

According to the RFC, the reserved characters are: :/?#[]@!$&'()*+,;=

And the unreserved characters are alphanumeric and -._~

The Verdict

Uri.EscapeDataString clearly defines its mission: %-encode all reserved and illegal characters. WebUtility.UrlEncode is more ambiguous in both definition and implementation. Oddly, it encodes some reserved characters but not others (why parentheses and not brackets??), and stranger still it encodes that innocently unreserved ~ character.

Therefore, I concur with the popular advice - use Uri.EscapeDataString when possible, and understand that reserved characters like / and ? will get encoded. If you need to deal with potentially large strings, particularly with URL-encoded form content, you'll need to either fall back on WebUtility.UrlEncode and accept its quirks, or otherwise work around the problem.

EDIT: I've attempted to rectify ALL of the quirks mentioned above in Flurl via the Url.Encode, Url.EncodeIllegalCharacters, and Url.Decode static methods. These are in the core package (which is tiny and doesn't include all the HTTP stuff), or feel free to rip them from the source. I welcome any comments/feedback you have on these.

Here's the code I used to discover which characters are encoded differently:

var diffs =
    from i in Enumerable.Range(0, char.MaxValue + 1)
    let c = (char)i
    where !char.IsHighSurrogate(c)
    let diff = new {
        Original = c,
        UrlEncode = WebUtility.UrlEncode(c.ToString()),
        EscapeDataString = Uri.EscapeDataString(c.ToString()),
    }
    where diff.UrlEncode != diff.EscapeDataString
    select diff;

foreach (var diff in diffs)
    Console.WriteLine($"{diff.Original}\t{diff.UrlEncode}\t{diff.EscapeDataString}");

I've added jsperf test to see the speed difference for different approaches to get the first child (total 1000+ children)

given, notif = $('#foo')

jQuery ways:

1. $(":first-child", notif) - 4,304 ops/sec - fastest
2. notif.children(":first") - 653 ops/sec - 85% slower
3. notif.children()[0] - 1,416 ops/sec - 67% slower

Native ways:

4. JavaScript native' ele.firstChild - 4,934,323 ops/sec (all the above approaches are 100% slower compared to firstChild)
5. Native DOM ele from jQery: notif[0].firstChild - 4,913,658 ops/sec

So, first 3 jQuery approaches are not recommended, at least for first-child (I doubt that would be the case with many other too). If you have a jQuery object and need to get the first-child, then get the native DOM element from the jQuery object, using array reference [0] (recommended) or .get(0) and use the ele.firstChild. This gives the same identical results as regular JavaScript usage.

all tests are done in Chrome Canary build v15.0.854.0

Aux routes syntax has changed with the new RC.3 router.

There are some known issues with aux routes but basic support is available.

You can define routes to show components in a named <router-outlet>

Route config

{path: 'chat', component: ChatCmp, outlet: 'aux'}

Named router outlet

<router-outlet name="aux">

Navigate aux routes

this._router.navigateByUrl("/crisis-center(aux:chat;open=true)");

It seems navigating aux routes from routerLink is not yet supported

<a [routerLink]="'/team/3(aux:/chat;open=true)'">Test</a>

<a [routerLink]="['/team/3', {outlets: {aux: 'chat'}}]">c</a>

Not tried myself yet

Your problem stems from a misunderstanding of the or operator that is common to people learning programming languages like this. Yes, your immediate problem can be solved by writing x ~= 0 and x ~= 1, but I'll go into a little more detail about why your attempted solution doesn't work.

When you read x ~=(0 or 1) or x ~= 0 or 1 it's natural to parse this as you would the sentence "x is not equal to zero or one". In the ordinary understanding of that statement, "x" is the subject, "is not equal to" is the predicate or verb phrase, and "zero or one" is the object, a set of possibilities joined by a conjunction. You apply the subject with the verb to each item in the set.

However, Lua does not parse this based on the rules of English grammar, it parses it in binary comparisons of two elements based on its order of operations. Each operator has a precedence which determines the order in which it will be evaluated. or has a lower precedence than ~=, just as addition in mathematics has a lower precedence than multiplication. Everything has a lower precedence than parentheses.

As a result, when evaluating x ~=(0 or 1), the interpreter will first compute 0 or 1 (because of the parentheses) and then x ~= the result of the first computation, and in the second example, it will compute x ~= 0 and then apply the result of that computation to or 1.

The logical operator or "returns its first argument if this value is different from nil and false; otherwise, or returns its second argument". The relational operator ~= is the inverse of the equality operator ==; it returns true if its arguments are different types (x is a number, right?), and otherwise compares its arguments normally.

Using these rules, x ~=(0 or 1) will decompose to x ~= 0 (after applying the or operator) and this will return 'true' if x is anything other than 0, including 1, which is undesirable. The other form, x ~= 0 or 1 will first evaluate x ~= 0 (which may return true or false, depending on the value of x). Then, it will decompose to one of false or 1 or true or 1. In the first case, the statement will return 1, and in the second case, the statement will return true. Because control structures in Lua only consider nil and false to be false, and anything else to be true, this will always enter the if statement, which is not what you want either.

There is no way that you can use binary operators like those provided in programming languages to compare a single variable to a list of values. Instead, you need to compare the variable to each value one by one. There are a few ways to do this. The simplest way is to use De Morgan's laws to express the statement 'not one or zero' (which can't be evaluated with binary operators) as 'not one and not zero', which can trivially be written with binary operators:

if x ~= 1 and x ~= 0 then
    print( "X must be equal to 1 or 0" )
    return
end

Alternatively, you can use a loop to check these values:

local x_is_ok = false
for i = 0,1 do 
    if x == i then
        x_is_ok = true
    end
end
if not x_is_ok then
    print( "X must be equal to 1 or 0" )
    return
end

Finally, you could use relational operators to check a range and then test that x was an integer in the range (you don't want 0.5, right?)

if not (x >= 0 and x <= 1 and math.floor(x) == x) then
    print( "X must be equal to 1 or 0" )
    return
end

Note that I wrote x >= 0 and x <= 1. If you understood the above explanation, you should now be able to explain why I didn't write 0 <= x <= 1, and what this erroneous expression would return!

What about a more direct approach?

if (Request.QueryString.AllKeys.Contains("mykey")

Suppose you have defined your route name like this:

https://localhost:3000/user/:userid

which will become:

https://localhost:3000/user/5896544

Here, if you will print: request.params

{
userId : 5896544
}

so

request.params.userId = 5896544

so request.params is an object containing properties to the named route

and request.query comes from query parameters in the URL eg:

https://localhost:3000/user?userId=5896544 

request.query

{

userId: 5896544

}

so

request.query.userId = 5896544

You can set specific cache-headers for a whole folder in either your root web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <!-- Note the use of the 'location' tag to specify which 
       folder this applies to-->
  <location path="images">
    <system.webServer>
      <staticContent>
        <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="00:00:15" />
      </staticContent>
    </system.webServer>
  </location>
</configuration>

Or you can specify these in a web.config file in the content folder:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="00:00:15" />
    </staticContent>
  </system.webServer>
</configuration>

I'm not aware of a built in mechanism to target specific file types.

It would help if you showed the code you are using for the simple test program. Put directly into the interpreter this seems to work.

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1, 2)
3
>>> 

Until CSS: image-orientation:from-image; is more universally supported we are doing a server side solution with python. Here's the gist of it. You check the exif data for orientation, then rotate the image accordingly and resave.

We prefer this solution over client side solutions as it does not require loading extra libraries client side, and this operation only has to happen one time on file upload.

if fileType == "image":
    exifToolCommand = "exiftool -j '%s'" % filePath
    exif = json.loads(subprocess.check_output(shlex.split(exifToolCommand), stderr=subprocess.PIPE))
    if 'Orientation' in exif[0]:
        findDegrees, = re.compile("([0-9]+)").search(exif[0]['Orientation']).groups()
        if findDegrees:
            rotateDegrees = int(findDegrees)
            if 'CW' in exif[0]['Orientation'] and 'CCW' not in exif[0]['Orientation']:
                rotateDegrees = rotateDegrees * -1
            # rotate image
            img = Image.open(filePath)
            img2 = img.rotate(rotateDegrees)
            img2.save(filePath)

What also works and is even nicer for long, multiline texts, is putting your text indented on the next line, after a pipe or greater-than sign:

text: >
    Op dit plein stond het hoofdkantoor van de NIROM: Nederlands Indische 
    Radio Omroep

A pipe preserves newlines, a gt-sign turns all the following lines into one long string.

[...] How should Java Comparator class be declared to sort the arrays by their first elements in decreasing order [...]

Here's a complete example using Java 8:

import java.util.*;

public class Test {

    public static void main(String args[]) {

        int[][] twoDim = { {1, 2}, {3, 7}, {8, 9}, {4, 2}, {5, 3} };

        Arrays.sort(twoDim, Comparator.comparingInt(a -> a[0])
                                      .reversed());

        System.out.println(Arrays.deepToString(twoDim));
    }
}

Output:

[[8, 9], [5, 3], [4, 2], [3, 7], [1, 2]]

For Java 7 you can do:

Arrays.sort(twoDim, new Comparator<int[]>() {
    @Override
    public int compare(int[] o1, int[] o2) {
        return Integer.compare(o2[0], o1[0]);
    }
});

If you unfortunate enough to work on Java 6 or older, you'd do:

Arrays.sort(twoDim, new Comparator<int[]>() {
    @Override
    public int compare(int[] o1, int[] o2) {
        return ((Integer) o2[0]).compareTo(o1[0]);
    }
});

I've tested all anwers, but they were all too slow for me. If you have Excel installed you can use the COM.

I thought initially it would be slower since it will load everything for the actual Excel application, but it isn't for huge files. Maybe because the algorithm for opening and saving files runs a heavily optimized compiled code, Microsoft guys make a lot of money for it after all.

import sys
import os
import glob
from win32com.client import Dispatch

def main(path):
    excel = Dispatch("Excel.Application")
    if is_full_path(path):
        process_file(excel, path)
    else:
        files = glob.glob(path)
        for file_path in files:
            process_file(excel, file_path)
    excel.Quit()

def process_file(excel, path):
    fullpath = os.path.abspath(path)
    full_csv_path = os.path.splitext(fullpath)[0] + '.csv'
    workbook = excel.Workbooks.Open(fullpath)
    workbook.Worksheets(1).SaveAs(full_csv_path, 6)
    workbook.Saved = 1
    workbook.Close()


def is_full_path(path):
    return path.find(":") > -1

if __name__ == '__main__':
    main(sys.argv[1])

This is very raw code and won't check for errors, print help or anything, it will just create a csv file for each file that matches the pattern you entered in the function so you can batch process a lot of files only launching excel application once.

Using an iframe to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).

Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.

In your HTML, you could set up a div to display the PDFs:

<div id="pdfRenderer"></div>

Then, you can have Javascript code to embed a PDF in that div:

var pdf = new PDFObject({
  url: "https://something.com/HTC_One_XL_User_Guide.pdf",
  id: "pdfRendered",
  pdfOpenParams: {
    view: "FitH"
  }
}).embed("pdfRenderer");

Code Complete recommends m_varname for member variables.

While I've never thought the m_ notation useful, I would give McConnell's opinion weight in building a standard.

If you are using Microsoft's Visual C++ 2010 Express and run into the issue with CTRL+F5 not working for keeping the console open after the program has terminated, take a look at this MSDN thread.

Likely your IDE is set to close the console after a CTRL+F5 run; in fact, an "Empty Project" in Visual C++ 2010 closes the console by default. To change this, do as the Microsoft Moderator suggested:

Please right click your project name and go to Properties page, please expand Configuration Properties -> Linker -> System, please select Console (/SUBSYSTEM:CONSOLE) in SubSystem dropdown. Because, by default, the Empty project does not specify it.

Here is the Query

select count(*) from tablename

or

select count(rownum) from studennt

This should work:

$(".hit").click(function(){    
   var value=$(this).closest('tr').children('td:first').text();
   alert(value);    
});

Explanation:

• .closest('tr') gets the nearest ancestor that is a <tr> element (so in this case the row where the <a> element is in).
• .children('td:first') gets all the children of this element, but with the :first selector we reduce it to the first <td> element.
• .text() gets the text inside the element

As you can see from the other answers, there is more than only one way to do this.

In one controller, you can do:

$rootScope.$broadcast('eventName', data);

and listen to the event in another:

$scope.$on('eventName', function (event, data) {...});

The ternary operator is just a shorthand for and if/else block. Your working code does not have an else condition, so is not suitable for this.

The following example will work:

echo empty($address['street2']) ? 'empty' : 'not empty';

Yo can set FlowDirection of Stack panel to RightToLeft, and then all items will be aligned to the right side.

I had trouble deleting a cookie made via JavaScript and after I added the host it worked (scroll the code below to the right to see the location.host). After clearing the cookies on a domain try the following to see the results:

if (document.cookie.length==0)
{
 document.cookie = 'name=example; expires='+new Date((new Date()).valueOf()+1000*60*60*24*15)+'; path=/; domain='+location.host;

 if (document.cookie.length==0) {alert('Cookies disabled');}
 else
 {
  document.cookie = 'name=example; expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/; domain='+location.host;

  if (document.cookie.length==0) {alert('Created AND deleted cookie successfully.');}
  else {alert('document.cookies.length = '+document.cookies.length);}
 }
}

Building the order by expression can be read here

Shamelessly stolen from the page in link:

// First we define the parameter that we are going to use
// in our OrderBy clause. This is the same as "(person =>"
// in the example above.
var param = Expression.Parameter(typeof(Person), "person");

// Now we'll make our lambda function that returns the
// "DateOfBirth" property by it's name.
var mySortExpression = Expression.Lambda<Func<Person, object>>(Expression.Property(param, "DateOfBirth"), param);

// Now I can sort my people list.
Person[] sortedPeople = people.OrderBy(mySortExpression).ToArray();

Use This one

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

If you want to open the Dialog immediately when the Dialog is initialized or the page is ready, you can also set the parameter autoOpen to true in the options object of dialog:

var opt = {
        autoOpen: true,
        modal: true,
        width: 550,
        height:650,
        title: 'Details'
};

Thus, you do not have to call the `$("#divDialog").dialog("open");

When dialog object is initialized, the dialog is automatically opened.

Verify that you can start your application like that:

java -cp myjarfile.jar snake.Controller

I just read when I double click on it - this sounds like a configuration issue with your operating system. You're double-clicking the file on a windows explorer window? Try to run it from a console/terminal with the command

java -jar myjarfile.jar

1. Spring is an IoC container (at least the core of Spring) and is used to wire things using dependency injection. Spring provides additional services like transaction management and seamless integration of various other technologies.
2. Struts is an action-based presentation framework (but don't use it for a new development).
3. Struts 2 is an action-based presentation framework, the version 2 of the above (created from a merge of WebWork with Struts).
4. Hibernate is an object-relational mapping tool, a persistence framework.
5. JavaServer Faces is component-based presentation framework.
6. JavaServer Pages is a view technology used by all mentioned presentation framework for the view.
7. Tapestry is another component-based presentation framework.

So, to summarize:

• Struts 2, JSF, Tapestry (and Wicket, Spring MVC, Stripes) are presentation frameworks. If you use one of them, you don't use another.
• Hibernate is a persistence framework and is used to persist Java objects in a relational database.
• Spring can be used to wire all this together and to provide declarative transaction management.

I don't want to make things more confusing but note that Java EE 6 provides modern, standardized and very nice equivalent of the above frameworks: JSF 2.0 and Facelets for the presentation, JPA 2.0 for the persistence, Dependency Injection, etc. For a new development, this is IMO a serious option, Java EE 6 is a great stack.

Hi,

Well, I have tried the methods mentioned above! it's working yes, but not exactly the way I wanted. I wanted to redirect the default page extension to the main domain with our further action.

Here how I do that...

# Accesible Index Page
<IfModule dir_module>
 DirectoryIndex index.php index.html
 RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.(html|htm|php|php3|php5|shtml|phtml) [NC]
 RewriteRule ^index\.html|htm|php|php3|php5|shtml|phtml$ / [R=301,L]
</IfModule>

The above code simply captures any index.* and redirect it to the main domain.

Thank you

If you always want to reload your module, you could add this function:

function requireUncached(module) {
    delete require.cache[require.resolve(module)];
    return require(module);
}

and then use requireUncached('./myModule') instead of require.

Please try my pre-commit hooks, it can auto detect trailing-whitespace and remove it. Thank you!

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
