I keep this function handy for whenever I need it, and change the column names and classes to suit the use case:

make_df <- function() { data.frame(name=character(),
                     profile=character(),
                     sector=character(),
                     type=character(),
                     year_range=character(),
                     link=character(),
                     stringsAsFactors = F)
}

make_df()
[1] name       profile    sector     type       year_range link      
<0 rows> (or 0-length row.names)

That’s a typo. You’ve accidently set user.mail with no e. Fix it by setting user.email in the global configuration with

git config --global user.email "[email protected]"

Following code will do the job and will allow you to specify field delimiter. This is especially useful for files containing more than 20k lines.

awk 'BEGIN { 
  FS="|"; 
  min=10000; 
}
{ 
  if( NF > max ) max = NF; 
  if( NF < min ) min = NF;
} 
END { 
  print "Max=" max; 
  print "Min=" min; 
} ' myPipeDelimitedFile.dat

Just summarising @libing's answer with a sample that worked for me.

val gson = Gson()
val todoItem: TodoItem = gson.fromJson(this.assets.readAssetsFile("versus.json"), TodoItem::class.java)

private fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}

Without this extension function the same can be achieved by using BufferedReader and InputStreamReader this way:

val i: InputStream = this.assets.open("versus.json")
val br = BufferedReader(InputStreamReader(i))
val todoItem: TodoItem = gson.fromJson(br, TodoItem::class.java)

Hi First write the Activity class. The following class have a Name of category and small add button. When you press on add (+) button it adds the new row which contains an EditText and an ImageButton which performs the delete of the row.

    android:id="@+id/addCategiryNameItem"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

        android:layout_height="wrap_content"
        android:text="@string/lbl_category_name"

        </LinearLayout>
    </ScrollView>
</LinearLayout>

3. Once you finished your view will as shown below

Just in case this helps someone, I was getting this error because I completely missed the stated fact that the scope prefix must not be used when calling a local scope. So if you defined a local scope in your model like this:

public function scopeRecentFirst($query)
{
    return $query->orderBy('updated_at', 'desc');
}

You should call it like:

$CurrentUsers = \App\Models\Users::recentFirst()->get();

Note that the prefix scope is not present in the call.

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),
               write_csv(data, "readr_file.csv"),
               fwrite(data, "datatable_file.csv"),
               times = 10, unit = "s")

## Unit: seconds
##                                              expr        min         lq       mean     median         uq        max neval
##  write.csv(data, "baseR_file.csv", row.names = F) 13.8066424 13.8248250 13.9118324 13.8776993 13.9269675 14.3241311    10
##                 write_csv(data, "readr_file.csv")  3.6742610  3.7999409  3.8572456  3.8690681  3.8991995  4.0637453    10
##                fwrite(data, "datatable_file.csv")  0.3976728  0.4014872  0.4097876  0.4061506  0.4159007  0.4355469    10

The cleanest way in modern Python >=3.6, is to use an f-string with string formatting:

>>> var = 1.6
>>> f"{var:.15f}"
'1.600000000000000'

As others have mentioned, the load data local infile works just fine. I tried the php script that Hawkee posted, but didnt work for me. Rather than debug it, here's what i did:

1) copy/paste the header row of the CSV file into a txt file and edit with emacs. add a comma and CR between each field to get each on on it's own line.
2) Save that file as FieldList.txt
3) edit the file to include defns for each field (most were varchar, but quite a few were int(x). Add create table tablename ( to the beginning of the file and ) to the end of the file. Save it as CreateTable.sql
4) start mysql client with input from the Createtable.sql file to create the table
5) start mysql client, copy/paste in most of the 'LOAD DATA INFILE' command subsituting my table name and csv file name. Paste in the FieldList.txt file. Be sure to include the 'IGNORE 1 LINES' before pasting in the field list

Sounds like a lot of work, but easy with emacs.....

If you want a distiction for this case I would recommend to use a matrix instead, where:

matrix([1,2,3]) == matrix([1,2,3]).transpose()

gives:

matrix([[ True, False, False],
        [False,  True, False],
        [False, False,  True]], dtype=bool)

You can also use a ndarray explicitly adding a second dimension:

array([1,2,3])[None,:]
#array([[1, 2, 3]])

and:

array([1,2,3])[:,None]
#array([[1],
#       [2],
#       [3]])

There are third-party implementations of interfaces for Python (most popular is Zope's, also used in Twisted), but more commonly Python coders prefer to use the richer concept known as an "Abstract Base Class" (ABC), which combines an interface with the possibility of having some implementation aspects there too. ABCs are particularly well supported in Python 2.6 and later, see the PEP, but even in earlier versions of Python they're normally seen as "the way to go" -- just define a class some of whose methods raise NotImplementedError so that subclasses will be on notice that they'd better override those methods!-)

I had a similar requirement in the app I am working on. And, I found a third-party library which does a slide-up, slide-down and slide-right in Android.

Refer to the link for more details: https://github.com/mancj/SlideUp-Android

To set up the library(copied from the ReadMe portion of its Github page on request):

Get SlideUp library

Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
    maven { url "https://maven.google.com" } // or google() in AS 3.0
  }
}

Add the dependency (in the Module gradle)

dependencies {
    compile 'com.github.mancj:SlideUp-Android:2.2.1'
    compile 'ru.ztrap:RxSlideUp2:2.x.x' //optional, for reactive listeners based on RxJava-2
    compile 'ru.ztrap:RxSlideUp:1.x.x' //optional, for reactive listeners based on RxJava
}

To add the SlideUp into your project, follow these three simple steps:

Step 1:

create any type of layout

<LinearLayout
  android:id="@+id/slideView"
  android:layout_width="match_parent"
  android:layout_height="match_parent"/>

Step 2:

Find that view in your activity/fragment

View slideView = findViewById(R.id.slideView);

Step 3:

Create a SlideUp object and pass in your view

slideUp = new SlideUpBuilder(slideView)
                .withStartState(SlideUp.State.HIDDEN)
                .withStartGravity(Gravity.BOTTOM)

                //.withSlideFromOtherView(anotherView)
                //.withGesturesEnabled()
                //.withHideSoftInputWhenDisplayed()
                //.withInterpolator()
                //.withAutoSlideDuration()
                //.withLoggingEnabled()
                //.withTouchableAreaPx()
                //.withTouchableAreaDp()
                //.withListeners()
                //.withSavedState()
                .build();

You may also refer to the sample project on the link. I found it quite useful.

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

Windows Mail seemed to outright ignore inline text-decoration tag but what fixed it for me was by adding this to the head:

<!--[if (mso)|(mso 16)]>
<style type="text/css">
    body, table, td, a, span { font-family: Arial, Helvetica, sans-serif !important; }
    a {text-decoration: none;}
</style>
<![endif]-->

Working code in this gist

Using Java 8 lambda's (added April 10, 2019)

Java 8 solves this nicely by lambda's (though Guava and Apache Commons might still offer more flexibility):

Collections.sort(reportList, Comparator.comparing(Report::getReportKey)
            .thenComparing(Report::getStudentNumber)
            .thenComparing(Report::getSchool));

Thanks to @gaoagong's answer below.

Messy and convoluted: Sorting by hand

Collections.sort(pizzas, new Comparator<Pizza>() {  
    @Override  
    public int compare(Pizza p1, Pizza p2) {  
        int sizeCmp = p1.size.compareTo(p2.size);  
        if (sizeCmp != 0) {  
            return sizeCmp;  
        }  
        int nrOfToppingsCmp = p1.nrOfToppings.compareTo(p2.nrOfToppings);  
        if (nrOfToppingsCmp != 0) {  
            return nrOfToppingsCmp;  
        }  
        return p1.name.compareTo(p2.name);  
    }  
});  

This requires a lot of typing, maintenance and is error prone.

The reflective way: Sorting with BeanComparator

ComparatorChain chain = new ComparatorChain(Arrays.asList(
   new BeanComparator("size"), 
   new BeanComparator("nrOfToppings"), 
   new BeanComparator("name")));

Collections.sort(pizzas, chain);  

Obviously this is more concise, but even more error prone as you lose your direct reference to the fields by using Strings instead (no typesafety, auto-refactorings). Now if a field is renamed, the compiler won’t even report a problem. Moreover, because this solution uses reflection, the sorting is much slower.

Getting there: Sorting with Google Guava’s ComparisonChain

Collections.sort(pizzas, new Comparator<Pizza>() {  
    @Override  
    public int compare(Pizza p1, Pizza p2) {  
        return ComparisonChain.start().compare(p1.size, p2.size).compare(p1.nrOfToppings, p2.nrOfToppings).compare(p1.name, p2.name).result();  
        // or in case the fields can be null:  
        /* 
        return ComparisonChain.start() 
           .compare(p1.size, p2.size, Ordering.natural().nullsLast()) 
           .compare(p1.nrOfToppings, p2.nrOfToppings, Ordering.natural().nullsLast()) 
           .compare(p1.name, p2.name, Ordering.natural().nullsLast()) 
           .result(); 
        */  
    }  
});  

This is much better, but requires some boiler plate code for the most common use case: null-values should be valued less by default. For null-fields, you have to provide an extra directive to Guava what to do in that case. This is a flexible mechanism if you want to do something specific, but often you want the default case (ie. 1, a, b, z, null).

Sorting with Apache Commons CompareToBuilder

Collections.sort(pizzas, new Comparator<Pizza>() {  
    @Override  
    public int compare(Pizza p1, Pizza p2) {  
        return new CompareToBuilder().append(p1.size, p2.size).append(p1.nrOfToppings, p2.nrOfToppings).append(p1.name, p2.name).toComparison();  
    }  
});  

Like Guava’s ComparisonChain, this library class sorts easily on multiple fields, but also defines default behavior for null values (ie. 1, a, b, z, null). However, you can’t specify anything else either, unless you provide your own Comparator.

Thus

Ultimately it comes down to flavor and the need for flexibility (Guava’s ComparisonChain) vs. concise code (Apache’s CompareToBuilder).

Bonus method

I found a nice solution that combines multiple comparators in order of priority on CodeReview in a MultiComparator:

class MultiComparator<T> implements Comparator<T> {
    private final List<Comparator<T>> comparators;

    public MultiComparator(List<Comparator<? super T>> comparators) {
        this.comparators = comparators;
    }

    public MultiComparator(Comparator<? super T>... comparators) {
        this(Arrays.asList(comparators));
    }

    public int compare(T o1, T o2) {
        for (Comparator<T> c : comparators) {
            int result = c.compare(o1, o2);
            if (result != 0) {
                return result;
            }
        }
        return 0;
    }

    public static <T> void sort(List<T> list, Comparator<? super T>... comparators) {
        Collections.sort(list, new MultiComparator<T>(comparators));
    }
}

Ofcourse Apache Commons Collections has a util for this already:

ComparatorUtils.chainedComparator(comparatorCollection)

Collections.sort(list, ComparatorUtils.chainedComparator(comparators));

Somewhere in your initialisation put this code.

Array.prototype.contains = function contains(obj) {
    for (var i = 0; i < this.length; i++) {
        if (this[i] === obj) {
            return true;
        }
    }
    return false;
};

Then, you can use it this way:

<li ng-class="{approved: selectedForApproval.contains(jobSet)}"></li>

ref():

Perl provides the ref() function so that you can check the reference type before dereferencing a reference...

By using the ref() function you can protect program code that dereferences variables from producing errors when the wrong type of reference is used...

Laravel is not actually that slow. 500-1000ms is absurd; I got it down to 20ms in debug mode.

The problem was Vagrant/VirtualBox + shared folders. I didn't realize they incurred such a performance hit. I guess because Laravel has so many dependencies (loads ~280 files) and each of those file reads is slow, it adds up really quick.

kreeves pointed me in the right direction, this blog post describes a new feature in Vagrant 1.5 that lets you rsync your files into the VM rather than using a shared folder.

There's no native rsync client on Windows, so you'll have to use cygwin. Install it, and make sure to check off Net/rsync. Add C:\cygwin64\bin to your paths. [Or you can install it on Win10/Bash]

Vagrant introduces the new feature. I'm using Puphet, so my Vagrantfile looks a bit funny. I had to tweak it to look like this:

  data['vm']['synced_folder'].each do |i, folder|
    if folder['source'] != '' && folder['target'] != '' && folder['id'] != ''
      config.vm.synced_folder "#{folder['source']}", "#{folder['target']}", 
        id: "#{folder['id']}", 
        type: "rsync",
        rsync__auto: "true",
        rsync__exclude: ".hg/"
    end
  end

Once you're all set up, try vagrant up. If everything goes smoothly your machine should boot up and it should copy all the files over. You'll need to run vagrant rsync-auto in a terminal to keep the files up to date. You'll pay a little bit in latency, but for 30x faster page loads, it's worth it!

If you're using PhpStorm, it's auto-upload feature works even better than rsync. PhpStorm creates a lot of temporary files which can trip up file watchers, but if you let it handle the uploads itself, it works nicely.

One more option is to use lsyncd. I've had great success using this on Ubuntu host -> FreeBSD guest. I haven't tried it on a Windows host yet.

This is a very old thread, but I still use Windows 7. :-)

There is one point that no one seems to have taken into account, which probably would help Windows 10 users also.

If Command Extensions are enabled, the PUSHD command accepts network paths in addition to the normal drive letter and path.

So the obvious - and simplest - answer might be to enable command extensions in the batch script, if you intend to use PUSHD. At the very least, this ought to reduce the problems you might have in using PUSHD wqith a network path.

openssl rsa -in f.pem -inform PEM -out f.der -outform DER

You have to get the host and path separately.

The Reverse Proxy method

• Method type: Ajax

Setting up a simple reverse proxy on the server, will allow the browser to use relative paths for the Ajax requests, while the server would be acting as a proxy to any remote location.

If using mod_proxy in Apache, the fundamental configuration directive to set up a reverse proxy is the ProxyPass. It is typically used as follows:

ProxyPass     /ajax/     http://other-domain.com/ajax/

In this case, the browser would be able to request /ajax/web_service.xml as a relative URL, but the server would serve this by acting as a proxy to http://other-domain.com/ajax/web_service.xml.

One interesting feature of the this method is that the reverse proxy can easily distribute requests towards multiple back-ends, thus acting as a load balancer.

The "Premature end of script headers" error message is probably the most loathed and common error message you'll find. What the error actually means, is that the script stopped for whatever reason before it returned any output to the web server. A common cause of this for script writers is to fail to set a content type before printing output code. In Perl for example, before printing any HTML it is necessary to tell the Perl script to set the content type to text/html, this is done by sending a header, like so:

print "Content-type: text/html\n\n";

First, Make sure that the current user is a member of Local Administrator Group on the server that running SSRS to can manage SSRS permissions,

Note: By default, the local admins have full permission to manage SSRS.

Now, try to do the following:

• Run Internet Explorer as Administrator.

• Browse the Report Manager URL.

• Provide the user that has a permission issue the required permission as mentioned at User does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed

Note: if the issue still exists, so it's not a permission issue, you need to adjust the Internet Explorer settings as mentioned at User does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed

Here's a code snippet to split a string by n characters separated over lines:

//: A UIKit based Playground for presenting user interface

import UIKit
import PlaygroundSupport

class MyViewController : UIViewController {
    override func loadView() {

        let str = String(charsPerLine: 5, "Hello World!")
        print(str) // "Hello\n Worl\nd!\n"

    }
}

extension String {

    init(charsPerLine:Int, _ str:String){

        self = ""
        var idx = 0
        for char in str {
            self += "\(char)"
            idx = idx + 1
            if idx == charsPerLine {
                self += "\n"
                idx = 0
            }
        }

    }
}

Try using double quotes if it's a char variable:

DEFINE stupidvar = "'stupidvarcontent'";

or

DEFINE stupidvar = 'stupidvarcontent';

SELECT stupiddata  
FROM stupidtable  
WHERE stupidcolumn = '&stupidvar'

I'm using iOS 9.3 and setting the color through the Storyboard or setting cell.selectionStyle didn't work for me, but the code below worked:

UIView *customColorView = [[UIView alloc] init];
customColorView.backgroundColor = [UIColor colorWithRed:55 / 255.0 
                                                  green:141 / 255.0

                                                  alpha:1.0];
cell.selectedBackgroundView = customColorView;

return cell;

I found this solution here.

The problem you are reporting seems to me caused by the following:

1. you are trying to compile C code and the source file has .cpp extension
2. you are trying to compile C++ code and the source file has .c extension

In such situation Eclipse cannot recognize the proper compiler to use.

If your structure should be like this:

/assets/html/index.html

/assets/scripts/index.js

/assets/css/index.css

Then just do ( Android WebView: handling orientation changes )

    if(WebViewStateHolder.INSTANCE.getBundle() == null) { //this works only on single instance of webview, use a map with TAG if you need more
        webView.loadUrl("file:///android_asset/html/index.html");
    } else {
        webView.restoreState(WebViewStateHolder.INSTANCE.getBundle());
    }

Make sure you add

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        webSettings.setAllowFileAccessFromFileURLs(true);
        webSettings.setAllowUniversalAccessFromFileURLs(true);
    }

Then just use urls

<html>
<head>
    <meta charset="utf-8">
    <title>Zzzz</title>
    <script src="../scripts/index.js"></script>
    <link rel="stylesheet" type="text/css" href="../css/index.css">

In my case, the app main Target's Team was different from Tests' Target Team. Changing the Tests' Team to the same Team as main Target's solves the issue.

Thread t1 = new Thread(new Runnable() {
    @Override
    public void run() {

new Thread(new Runnable() {
     @Override
     public void run() {
          // code goes here.
     }
}).start();

or

new Thread(() -> {
    // code goes here.
}).start();

or

Executors.newSingleThreadExecutor().execute(new Runnable() {
    @Override
    public void run() {
        myCustomMethod();
    }

        myCustomMethod();
    }

if (!is_dir('path_directory')) {
    @mkdir('path_directory');

1- Install compression

npm install compression

2- Use it

var compression = require('compression')

var app = express()

If you are using this for Angular, then export a function via a named export. Such as:

function someFunc(){}

export { someFunc as someFuncName }

otherwise, Angular will complain that object is not a function.

I think your question is, "why am I getting one more line than there is in the file?"

Imagine a file:

line 1
line 2
line 3

The file may be represented in ASCII like this:

line 1\nline 2\nline 3\n

(Where \n is byte 0x10.)

Now let's see what happens before and after each getline call:

Before 1: line 1\nline 2\nline 3\n
  Stream: ^
After 1:  line 1\nline 2\nline 3\n
  Stream:         ^

Before 2: line 1\nline 2\nline 3\n
  Stream:         ^
After 2:  line 1\nline 2\nline 3\n
  Stream:                 ^

Before 2: line 1\nline 2\nline 3\n
  Stream:                 ^
After 2:  line 1\nline 2\nline 3\n
  Stream:                         ^

Now, you'd think the stream would mark eof to indicate the end of the file, right? Nope! This is because getline sets eof if the end-of-file marker is reached "during it's operation". Because getline terminates when it reaches \n, the end-of-file marker isn't read, and eof isn't flagged. Thus, myfile.eof() returns false, and the loop goes through another iteration:

Before 3: line 1\nline 2\nline 3\n
  Stream:                         ^
After 3:  line 1\nline 2\nline 3\n
  Stream:                         ^ EOF

How do you fix this? Instead of checking for eof(), see if .peek() returns EOF:

while(myfile.peek() != EOF){
    getline ...

You can also check the return value of getline (implicitly casting to bool):

while(getline(myfile,line)){
    cout<< ...

we can write the UTF-8 encoded file with java using use PrintWriter to write UTF-8 encoded xml

Or Click here

PrintWriter out1 = new PrintWriter(new File("C:\\abc.xml"), "UTF-8");

My case is when using two factor auth, outlook account and VS12.

I found out I have to

• open IE (my corporate default browser)
• log in to visual studio online account (including two factor auth)
• connect again in VS12 (do the auth again for some reason)

You should not initialize your variable to an empty object, but let it be undefined or null until the conditions exist where it should have a non-null/undefined value:

$scope.card;

if (someCondition = true) {
    $scope.card = {};
}

Then your template:

ng-show="card"

Use this overload (RenderPartialExtensions.RenderPartial on MSDN):

public static void RenderPartial(
    this HtmlHelper htmlHelper,
    string partialViewName,
    Object model
)

so:

@{Html.RenderPartial(
    "FullName",
    new { firstName = model.FirstName, lastName = model.LastName});
}

you have to set the tableName you want to your dtimage that is for instance

dtImage.TableName="mydtimage";


if(!ds.Tables.Contains(dtImage.TableName))
        ds.Tables.Add(dtImage);

it will be reflected in dataset because dataset is a container of your datatable dtimage and you have a reference on your dtimage

            b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
            String path = MediaStore.Images.Media.insertImage(requireActivity().getContentResolver(),
                    b, "Title", null);
            Uri imageUri = Uri.parse(path);
            share.putExtra(Intent.EXTRA_STREAM, imageUri);
            share.putExtra(Intent.EXTRA_TEXT, "Here is text");
            startActivity(Intent.createChooser(share, "Share via"));
        });

If by "application startup" you mean "application context startup", then yes, there are many ways to do this, the easiest (for singletons beans, anyway) being to annotate your method with @PostConstruct. Take a look at the link to see the other options, but in summary they are:

• Methods annotated with @PostConstruct
• afterPropertiesSet() as defined by the InitializingBean callback interface
• A custom configured init() method

Technically, these are hooks into the bean lifecycle, rather than the context lifecycle, but in 99% of cases, the two are equivalent.

If you need to hook specifically into the context startup/shutdown, then you can implement the Lifecycle interface instead, but that's probably unnecessary.

From HandlerIntercepter's javadoc:

HandlerInterceptor is basically similar to a Servlet Filter, but in contrast to the latter it just allows custom pre-processing with the option of prohibiting the execution of the handler itself, and custom post-processing. Filters are more powerful, for example they allow for exchanging the request and response objects that are handed down the chain. Note that a filter gets configured in web.xml, a HandlerInterceptor in the application context.

As a basic guideline, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

With that being said:

So where is the difference between Interceptor#postHandle() and Filter#doFilter()?

postHandle will be called after handler method invocation but before the view being rendered. So, you can add more model objects to the view but you can not change the HttpServletResponse since it's already committed.

doFilter is much more versatile than the postHandle. You can change the request or response and pass it to the chain or even block the request processing.

Also, in preHandle and postHandle methods, you have access to the HandlerMethod that processed the request. So, you can add pre/post-processing logic based on the handler itself. For example, you can add a logic for handler methods that have some annotations.

What is the best practise in which use cases it should be used?

As the doc said, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

<script type="text/javascript">
$(document).ready(function(){

    });
}
</script>

An output reg foo is just shorthand for output foo_wire; reg foo; assign foo_wire = foo. It's handy when you plan to register that output anyway. I don't think input reg is meaningful for module (perhaps task). input wire and output wire are the same as input and output: it's just more explicit.

Arraylist narraylist=Arrays.asList(); // Returns immutable arraylist To make it mutable solution would be: Arraylist narraylist=new ArrayList(Arrays.asList());

You need

$('selector').dialog('close');

Best is not using regex for everything. Those requirements are very light. On CPU-wise string operations for checking the criteria/validation is much cheaper and faster than regex!

$(".clscss-row").each(function () {
if ($(this).find(".po-checkbox").not(":checked")) {
               // enter your code here
            } });

“JSONP is JSON with extra code” would be too easy for the real world. No, you gotta have little discrepancies. What’s the fun in programming if everything just works?

Turns out JSON is not a subset of JavaScript. If all you do is take a JSON object and wrap it in a function call, one day you will be bitten by strange syntax errors, like I was today.

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015 > 01/02/2016 because 09 > 01. You need to either put your date in a comparable string format or compare DateTime objects which are comparable.

<?php
 $date_now = date("Y-m-d"); // this format is string comparable

if ($date_now > '2016-01-02') {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Or

<?php
 $date_now = new DateTime();
 $date2    = new DateTime("01/02/2016");

if ($date_now > $date2) {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Others are suggesting a wrapping div but you should be able to do this without adding complexity to your html...

check this out:

#message {
  box-sizing: border-box;
  padding: 8px;
}

This will work for null able dateTime parameter

. .

SearchUsingDate(DateTime? StartDate, DateTime? EndDate){
     DateTime LastDate;
     if (EndDate != null)
       {
          LastDate = (DateTime)EndDate;
          LastDate = LastDate.AddDays(1);
          EndDate = LastDate;
        }
}

Edit There appears to be a better LZW solution that handles Unicode strings correctly at http://pieroxy.net/blog/pages/lz-string/index.html (Thanks to pieroxy in the comments).

I don't know of any gzip implementations, but the jsolait library (the site seems to have gone away) has functions for LZW compression/decompression. The code is covered under the LGPL.

// LZW-compress a string
function lzw_encode(s) {
    var dict = {};
    var data = (s + "").split("");
    var out = [];
    var currChar;
    var phrase = data[0];
    var code = 256;
    for (var i=1; i<data.length; i++) {
        currChar=data[i];
        if (dict[phrase + currChar] != null) {
            phrase += currChar;
        }
        else {
            out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
            dict[phrase + currChar] = code;
            code++;
            phrase=currChar;
        }
    }
    out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
    for (var i=0; i<out.length; i++) {
        out[i] = String.fromCharCode(out[i]);
    }
    return out.join("");
}

// Decompress an LZW-encoded string
function lzw_decode(s) {
    var dict = {};
    var data = (s + "").split("");
    var currChar = data[0];
    var oldPhrase = currChar;
    var out = [currChar];
    var code = 256;
    var phrase;
    for (var i=1; i<data.length; i++) {
        var currCode = data[i].charCodeAt(0);
        if (currCode < 256) {
            phrase = data[i];
        }
        else {
           phrase = dict[currCode] ? dict[currCode] : (oldPhrase + currChar);
        }
        out.push(phrase);
        currChar = phrase.charAt(0);
        dict[code] = oldPhrase + currChar;
        code++;
        oldPhrase = phrase;
    }
    return out.join("");
}

Unless you need to identify the columns automatically, I found this to be the simplest solution:

df$name <- as.factor(df$name)

This makes column name in dataframe df a factor.

It looks like it is a bug open for this issue: Prettier Bug

None of above solution worked for me. The only thing that worked was, adding this line of code in package.json:

"prettier": {
    "singleQuote": true
  },

One of the dummies ways to determine if .NET Core is installed on Windows is:

• Press Windows + R
• Type cmd
• On the command prompt, type dotnet --version

If the .NET Core is installed, we should not get any error in the above steps.

You don't have a field named user_email in the members table ... as for why, I'm not sure as the code "looks" like it should try to join on different fields

Does the Auth::attempt method perform a join of the schema? Run grep -Rl 'class Auth' /path/to/framework and find where the attempt method is and what it does.

Edit: 2020-05-08: Is seems the website I quoted is no longer controlled by the person who wrote the advice, so I'm removing the link to the site. Thanks for letting me know baxx.

If someone's still struggling a bit after the great answers already provided, I found advice on a website that no longer is available.

Essential quote from the site I mentioned:

"The same can be specified programmatically in this way:

import sys

sys.path.append('..')

Of course the code above must be written before the other import statement.

It's pretty obvious that it has to be this way, thinking on it after the fact. I was trying to use the sys.path.append('..') in my tests, but ran into the issue posted by OP. By adding the import and sys.path defintion before my other imports, I was able to solve the problem.

I've had the same issue after using a web.config from another machine. The problem was related with an invalid MachineKey. To solve the problem, I modified the web.config to use the correct MachineKey of my server.

This MSDN blog post shows how to generate a MachineKey.

>>> source_list = ('1','a'),('2','b'),('3','c'),('4','d')
>>> list1, list2 = zip(*source_list)
>>> list1
('1', '2', '3', '4')
>>> list2
('a', 'b', 'c', 'd')

Edit: Note that zip(*iterable) is its own inverse:

>>> list(source_list) == zip(*zip(*source_list))
True

When unpacking into two lists, this becomes:

>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

Better:

if cells(i,1)="" then 
nextEmpty=i: 
exit for

Just add weightSum tag to linearlayout to 1 and for the corresponding view beneath it give layout_weight as .9 it will create a space between the views. You can experiment with the values to get appropriate value for you.

There is a combination of techniques which I found useful in solving this issue:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    contents.insert(index, new_string)  # new_string should end in a newline
    fd.seek(0)  # readlines consumes the iterator, so we need to start over
    fd.writelines(contents)  # No need to truncate as we are increasing filesize

In our particular application, we wanted to add it after a certain string:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    if match_string in contents[-1]:  # Handle last line to prevent IndexError
        contents.append(insert_string)
    else:
        for index, line in enumerate(contents):
            if match_string in line and insert_string not in contents[index + 1]:
                contents.insert(index + 1, insert_string)
                break
    fd.seek(0)
    fd.writelines(contents)

If you want it to insert the string after every instance of the match, instead of just the first, remove the else: (and properly unindent) and the break.

Note also that the and insert_string not in contents[index + 1]: prevents it from adding more than one copy after the match_string, so it's safe to run repeatedly.

If you've already installed Android Studio --

Add the following lines to the end of ~/.bashrc or ~/.zshrc (if using Oh My ZSH):

export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Restart Terminal and you're good to go.

More correct variant:

{
struct timespec delta = {5 /*secs*/, 135 /*nanosecs*/};
while (nanosleep(&delta, &delta));
}

The difference between

import java.util.*;

and

import java.util.*;
import java.util.List;
import java.util.Arrays;

becomes apparent when the code refers to some other List or Arrays (for example, in the same package, or also imported generally). In the first case, the compiler will assume that the Arrays declared in the same package is the one to use, in the latter, since it is declared specifically, the more specific java.util.Arrays will be used.

We can simply pass the output of python inbuilt print function to a file after opening the file with the append option by using just two lines of code:

with open('filename.txt', 'a') as file:
    print('\nThis printed data will store in a file', file=file)

Hope this may resolve the issue...

Note: this code works with python3 however, python2 is not being supported currently.

The foreach loops work just fine, but you can also simply

print_r($_POST);

Or for pretty printing in a browser:

echo "<pre>";
print_r($_POST);
echo "</pre>";

To find the sessions, as a DBA use

select sid,serial# from v$session where username = '<your_schema>'

If you want to be sure only to get the sessions that use SQL Developer, you can add and program = 'SQL Developer'. If you only want to kill sessions belonging to a specific developer, you can add a restriction on os_user

Then kill them with

alter system kill session '<sid>,<serial#>'

(e.g. alter system kill session '39,1232')

A query that produces ready-built kill-statements could be

select 'alter system kill session ''' || sid || ',' || serial# || ''';' from v$session where username = '<your_schema>'

This will return one kill statement per session for that user - something like:

alter system kill session '375,64855';

alter system kill session '346,53146';

Use element.closest()

https://developer.mozilla.org/en-US/docs/Web/API/Element/closest

See this example DOM:

<article>
  <div id="div-01">Here is div-01
    <div id="div-02">Here is div-02
      <div id="div-03">Here is div-03</div>
    </div>
  </div>
</article>

This is how you would use element.closest:

var el = document.getElementById('div-03');

var r1 = el.closest("#div-02");  
// returns the element with the id=div-02

var r2 = el.closest("div div");  
// returns the closest ancestor which is a div in div, here is div-03 itself

var r3 = el.closest("article > div");  
// returns the closest ancestor which is a div and has a parent article, here is div-01

var r4 = el.closest(":not(div)");
// returns the closest ancestor which is not a div, here is the outmost article

1. Go to Gradle tab in Android Studio , then select library project .

2. Then go to Tasks

3. Then go to Other

4. Double click on bundleReleaseaar

You can find your .aar files under your_module/build/outputs/aar/your-release.aar

You could also create a trigger that will calculate the sum before each insert

delimiter |

CREATE TRIGGER calCumluativeSum  BEFORE INSERT ON someTable
  FOR EACH ROW BEGIN

  SET cumulative_sum = (
     SELECT SUM(x.count)
        FROM someTable x
        WHERE x.id <= NEW.id
    )

    set  NEW.cumulative_sum = cumulative_sum;
  END;

I have not tested this

Different ways to handle button event

Fall into this using Amazon SDK v2, Windows 10 and JDK8. Amazon SDK was complaining about credentials loading.
I solved this by replacing the security/cacert file of JDK8 by the JDK11 one.

You can also enter msinfo32 into the command line.

It will bring up all your system information. Then, in the find box, just enter processor and it will show you your cores and logical processors for each CPU. I found this way to be easiest.

In standard C lua, no. You will have to settle for seconds, unless you are willing to modify the lua interpreter yourself to have os.time use the resolution you want. That may be unacceptable, however, if you are writing code for other people to run on their own and not something like a web application where you have full control of the environment.

Edit: another option is to write your own small DLL in C that extends lua with a new function that would give you the values you want, and require that dll be distributed with your code to whomever is going to be using it.

Just remove css from your js fiddle, ng-show will controll it. AngularJS sets the display style to none (using an !important flag). And remove this class when it must be shown.

Use VirtualBox. Create a machine on the drive you wish. Enable guest aditions and activate seamless mode.

Benefits:

• The ENTIRE installation is on the second drive. will work even with a 32gb ssd. (This is the main selling point, considering that Visual studio with it's additional features exceeds 30gb. If you have the GB to spare this solution is NOT the best for you)
• Uninstalling or backing up is a breeze. Just delete or move the image file. No system file conflicts and dirty registry in case of a corrupted installation.

Drawbacks:

• You need a LOT of ram. I use 4GB (out of 8) and 2 (out of 6) cores to run comfortably. Even so it is still slower than a normal installation.
• Will not work for applications with extensive 3d graphics. If you want to work with forms it's fine but if you want to create a 3d game for android using say xamarin then forget it.
• Testing the program takes several seconds to compile (minutes for android apps). This may not seem much but during development these seconds do add up.

This is the solution i am using and am very happy with it but i am not your average professional programmer. I just create small windows form applications like file uploaders, chat apps etc. Try it out. It will take some time to setup but this experimentation isn't risky.

Updating the path as listed above in ~/.bashrc makes other bash commands stop working altogether.

the easiest way I found is to use what eaykin did but link it your /bin.

sudo ln -s /android/platform-tools/adb /bin/adb

No restart is required just type following command :

adb devices

To make sure it's working.

In case the accepted answer by Wadih didn't work for you, try echo %CD%

I just stumbled onto this issue accessing some Python libraries: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools". The latest link to that is actually here: https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019

When you begin the installer, it will have several "options" enabled which will balloon the install size to 5gb. If you have Windows 10, you'll need to leave selected the "Windows 10 SDK" option as mentioned here.

I hope it helps save others time!

For modifying the status I think a RESTful approach is to use a logical sub-resource which describes the status of the resources. This IMO is pretty useful and clean when you have a reduced set of statuses. It makes your API more expressive without forcing the existing operations for your customer resource.

Example:

POST /customer/active  <-- Providing entity in the body a new customer
{
  ...  // attributes here except status
}

The POST service should return the newly created customer with the id:

{
    id:123,
    ...  // the other fields here
}

The GET for the created resource would use the resource location:

GET /customer/123/active

A GET /customer/123/inactive should return 404

For the PUT operation, without providing a Json entity it will just update the status

PUT /customer/123/inactive  <-- Deactivating an existing customer

Providing an entity will allow you to update the contents of the customer and update the status at the same time.

PUT /customer/123/inactive
{
    ...  // entity fields here except id and status
}

You are creating a conceptual sub-resource for your customer resource. It is also consistent with Roy Fielding's definition of a resource: "...A resource is a conceptual mapping to a set of entities, not the entity that corresponds to the mapping at any particular point in time..." In this case the conceptual mapping is active-customer to customer with status=ACTIVE.

Read operation:

GET /customer/123/active 
GET /customer/123/inactive

If you make those calls one right after the other one of them must return status 404, the successful output may not include the status as it is implicit. Of course you can still use GET /customer/123?status=ACTIVE|INACTIVE to query the customer resource directly.

The DELETE operation is interesting as the semantics can be confusing. But you have the option of not publishing that operation for this conceptual resource, or use it in accordance with your business logic.

DELETE /customer/123/active

That one can take your customer to a DELETED/DISABLED status or to the opposite status (ACTIVE/INACTIVE).

What you are asking is possible; but that will only work on a specific browser. You have to develop a browser extension app to achieve this. You can read more about chrome api to understand better. https://developer.chrome.com/extensions/cookies

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

You should do it like this:

\i path_to_sql_file

See:

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

Using reduce we can verify if each path exists and create it if necessary, also this way I think it is easier to follow. Edited, thanks @Arvin, we should use path.sep to get the proper platform-specific path segment separator.

const path = require('path');

// Path separators could change depending on the platform
const pathToCreate = 'path/to/dir'; 
pathToCreate
 .split(path.sep)
 .reduce((prevPath, folder) => {
   const currentPath = path.join(prevPath, folder, path.sep);
   if (!fs.existsSync(currentPath)){
     fs.mkdirSync(currentPath);
   }
   return currentPath;
 }, '');

In my case i just pass the wrong view to the Method

A functional requirement describes what a software system should do, while non-functional requirements place constraints on how the system will do so.

Let me elaborate.

An example of a functional requirement would be:

• A system must send an email whenever a certain condition is met (e.g. an order is placed, a customer signs up, etc).

A related non-functional requirement for the system may be:

• Emails should be sent with a latency of no greater than 12 hours from such an activity.

The functional requirement is describing the behavior of the system as it relates to the system's functionality. The non-functional requirement elaborates a performance characteristic of the system.

Typically non-functional requirements fall into areas such as:

• Accessibility
• Capacity, current and forecast
• Compliance
• Documentation
• Disaster recovery
• Efficiency
• Effectiveness
• Extensibility
• Fault tolerance
• Interoperability
• Maintainability
• Privacy
• Portability
• Quality
• Reliability
• Resilience
• Response time
• Robustness
• Scalability
• Security
• Stability
• Supportability
• Testability

A more complete list is available at Wikipedia's entry for non-functional requirements.

Non-functional requirements are sometimes defined in terms of metrics (i.e. something that can be measured about the system) to make them more tangible. Non-functional requirements may also describe aspects of the system that don't relate to its execution, but rather to its evolution over time (e.g. maintainability, extensibility, documentation, etc.).

Just for the sake of completeness, appending values to a vector in a for loop is not really the philosophy in R. R works better by operating on vectors as a whole, as @BrodieG pointed out. See if your code can't be rewritten as:

ouput <- sapply(values, function(v) return(2*v))

Output will be a vector of return values. You can also use lapply if values is a list instead of a vector.

If Maven update snapshot doesn't work and if you have Spring Tooling, one interesting way is to remove

Note: Maven update snapshot sometimes stops working if you use anything else i.e. eclipse:eclipse or Spring Tooling

There are vary solutions about this, but I couldn't find a whole thing. So I made my own solution for :

nicinfo

How to use :

NICInfoSummary* summary = [[[NICInfoSummary alloc] init] autorelease];

// en0 is for WiFi 
NICInfo* wifi_info = [summary findNICInfo:@"en0"];

// you can get mac address in 'XX-XX-XX-XX-XX-XX' form
NSString* mac_address = [wifi_info getMacAddressWithSeparator:@"-"];

// ip can be multiple
if(wifi_info.nicIPInfos.count > 0)
{
    NICIPInfo* ip_info = [wifi_info.nicIPInfos objectAtIndex:0];
    NSString* ip = ip_info.ip;
    NSString* netmask = ip_info.netmask;
    NSString* broadcast_ip = ip_info.broadcastIP;
}
else
{
    NSLog(@"WiFi not connected!");
}

What worked for me was to rename the project by removing the special characters.

Example: "project_marketplace" to "projectmarketplace"

In this case, I redid the project with react-native init and copied the src and package.json folder.

I noticed something else about your coding.... look

INSERT INTO reports_services (id,title,description,cost) VALUES (0, 'test title', 'test decription ', '3.80')

in your "CREATE TABLE" code you have the id set to "AUTO_INCREMENT" which means it's automatically generating a result for that field.... but in your above code you include it as one of the insertions and in the "VALUES" you have a 0 there... idk if that's your way of telling us you left it blank because it's set to AUTO_INC. or if that's the actual code you have... if it's the code you have not only should you not be trying to send data to a field set to generate it automatically, but the RIGHT WAY to do it WRONG would be

'0',

you put

0,

lol....so that might be causing some of the problem... I also just noticed in the code after "test description" you have a space before the '.... that might be throwing something off too.... idk.. I hope this helps n maybe resolves some other problem you might be pulling your hair out about now.... speaking of which.... I need to figure out my problem before I tear all my hair out..... good luck.. :)

UPDATE.....

I almost forgot... if you have the 0 there to show that it's blank... you could be entering "test title" as the id and "test description" as the title then "3.whatever cents" for the description leaving "cost" empty...... which could be why it maxed out because if I'm not mistaking you have it set to NOT NULL.... and you left it null... so it forced something... maybe.... lol

git reflog show should show you the history of HEAD. You can use that to figure out where you were before the pull. Then you can reset your HEAD to that commit.

One variant with only one loop for copying of all folders and files:

foreach (var f in Directory.GetFileSystemEntries(path, "*", SearchOption.AllDirectories))
{
    var output = Regex.Replace(f, @"^" + path, newPath);
    if (File.Exists(f)) File.Copy(f, output, true);
    else Directory.CreateDirectory(output);
}

Yeah.

command >> file to redirect just stdout of command.

command >> file 2>&1 to redirect stdout and stderr to the file (works in bash, zsh)

And if you need to use sudo, remember that just

sudo command >> /file/requiring/sudo/privileges does not work, as privilege elevation applies to command but not shell redirection part. However, simply using tee solves the problem:

command | sudo tee -a /file/requiring/sudo/privileges

Much simpler: use sudo to run a shell and use a heredoc to feed it commands.

Mmhh I know you've already discarded URLEncoder, but despite of what the docs say, I decided to give it a try.

You said:

For example, given an input:

http://google.com/resource?key=value

I expect the output:

http%3a%2f%2fgoogle.com%2fresource%3fkey%3dvalue

So:

C:\oreyes\samples\java\URL>type URLEncodeSample.java
import java.net.*;

public class URLEncodeSample {
    public static void main( String [] args ) throws Throwable {
        System.out.println( URLEncoder.encode( args[0], "UTF-8" ));
    }
}

C:\oreyes\samples\java\URL>javac URLEncodeSample.java

C:\oreyes\samples\java\URL>java URLEncodeSample "http://google.com/resource?key=value"
http%3A%2F%2Fgoogle.com%2Fresource%3Fkey%3Dvalue

As expected.

What would be the problem with this?

Use this it should be helpful to you. Slightly modified xbakesx answer.

Intent intent = new Intent(this, LoginActivity.class);
if(Build.VERSION.SDK_INT >= 11) {
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);
} else {
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
}
startActivity(intent);

You want:

int rowNumber=...;
string value = driver.findElement(By.xpath("//div[@id='productOrderContainer']/table/tbody/tr[" + rowNumber +"]/div[id='something']")).getText();

In other words, locate <DIV> with the id "something" contained within the rowNumberth <TR> of the <TABLE> contained within the <DIV> with the id "productOrderContainer", and then get its text value (which is what I believe you mean by "get me the value in <div id='something'>"

You need to add it to an axes. A Circle is a subclass of an Patch, and an axes has an add_patch method. (You can also use add_artist but it's not recommended.)

Here's an example of doing this:

import matplotlib.pyplot as plt

circle1 = plt.Circle((0, 0), 0.2, color='r')
circle2 = plt.Circle((0.5, 0.5), 0.2, color='blue')
circle3 = plt.Circle((1, 1), 0.2, color='g', clip_on=False)

fig, ax = plt.subplots() # note we must use plt.subplots, not plt.subplot
# (or if you have an existing figure)
# fig = plt.gcf()
# ax = fig.gca()

ax.add_patch(circle1)
ax.add_patch(circle2)
ax.add_patch(circle3)

fig.savefig('plotcircles.png')

This results in the following figure:

The first circle is at the origin, but by default clip_on is True, so the circle is clipped when ever it extends beyond the axes. The third (green) circle shows what happens when you don't clip the Artist. It extends beyond the axes (but not beyond the figure, ie the figure size is not automatically adjusted to plot all of your artists).

The units for x, y and radius correspond to data units by default. In this case, I didn't plot anything on my axes (fig.gca() returns the current axes), and since the limits have never been set, they defaults to an x and y range from 0 to 1.

Here's a continuation of the example, showing how units matter:

circle1 = plt.Circle((0, 0), 2, color='r')
# now make a circle with no fill, which is good for hi-lighting key results
circle2 = plt.Circle((5, 5), 0.5, color='b', fill=False)
circle3 = plt.Circle((10, 10), 2, color='g', clip_on=False)
    
ax = plt.gca()
ax.cla() # clear things for fresh plot

# change default range so that new circles will work
ax.set_xlim((0, 10))
ax.set_ylim((0, 10))
# some data
ax.plot(range(11), 'o', color='black')
# key data point that we are encircling
ax.plot((5), (5), 'o', color='y')
    
ax.add_patch(circle1)
ax.add_patch(circle2)
ax.add_patch(circle3)
fig.savefig('plotcircles2.png')

which results in:

You can see how I set the fill of the 2nd circle to False, which is useful for encircling key results (like my yellow data point).

Example 2 on w3schools shows what you are trying to achieve.

<?php
header("Content-type:application/pdf");

// It will be called downloaded.pdf
header("Content-Disposition:attachment;filename='downloaded.pdf'");

// The PDF source is in original.pdf
readfile("original.pdf");
?>

Also remember that,

It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)

I know I'm 4 years late but my answer is for anyone who may not have figured it out. I'm using a Samsung Galaxy S6, what worked for me was:

1. Disable USB debugging

2. Disable Developer mode

3. Unplug the device from the USB cable

4. Re-enable Developer mode

5. Re-enable USB debugging

6. Reconnect the USB cable to your device

It is important you do it in this order as it didn't work until it was done in this order.

Config file:

worker_processes  4;  # 2 * Number of CPUs

events {
    worker_connections  19000;  # It's the key to high performance - have a lot of connections available
}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections

I added the following code in proguard file.

-keep public class * extends android.app.Activity_x000D_
-keep public class * extends android.app.Application

and it worked in my case.

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

For CSS that are reused among the entire site I define them in the <head> section of the _Layout:

<head>
    <link href="@Url.Content("~/Styles/main.css")" rel="stylesheet" type="text/css" />
    @RenderSection("Styles", false)
</head>

and if I need some view specific styles I define the Styles section in each view:

@section Styles {
    <link href="@Url.Content("~/Styles/view_specific_style.css")" rel="stylesheet" type="text/css" />
}

Edit: It's useful to know that the second parameter in @RenderSection, false, means that the section is not required on a view that uses this master page, and the view engine will blissfully ignore the fact that there is no "Styles" section defined in your view. If true, the view won't render and an error will be thrown unless the "Styles" section has been defined.

If your VARCHAR column contains empty strings (which are not the same as NULL for PostgreSQL as you might recall) you will have to use something in the line of the following to set a default:

ALTER TABLE presales ALTER COLUMN code TYPE NUMERIC(10,0)
            USING COALESCE(NULLIF(code, '')::NUMERIC, 0);

after cloning a fork you have to explicitly add a remote upstream, with git add remote "the original repo you forked from". This becomes your upstream, you mostly fetch and merge from your upstream. Any other business such as pushing from your local to upstream should be done using pull request.

https://rhodecode.com is an open source web app for Git & Mercurial which can be very easily installed under any operating system (an installer is included).

RhodeCode (the new version is called RhodeCode Enterprise) adds missing Git features like code review and it is generally speaking very fast and reliable.

Checkout gunzip-file

import gunzip from 'gunzip-file';

const unzipAll = async () => {
  try {
    const compFiles = fs.readdirSync('tmp')
    await Promise.all(compFiles.map( async file => {
      if(file.endsWith(".gz")){
        gunzip(`tmp/${file}`, `tmp/${file.slice(0, -3)}`)
      }
    }));
  }
  catch(err) {
    console.log(err)
  }
}

Get rid of the semicolon after WordGame.

You really should have discovered this problem when the class was a lot smaller. When you're writing code, you should be compiling about every time you add half a dozen lines.

I am using below code for today and database date.

TIMESTAMPDIFF(MINUTE,T.runTime,NOW()) > 20

According to the documentation, the first argument can be any of the following:

MICROSECOND
SECOND
MINUTE
HOUR
DAY
WEEK
MONTH
QUARTER
YEAR

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

Yes, Spring framework logging is very detailed, You did not mention in your post, if you are already using a logging framework or not. If you are using log4j then just add spring appenders to the log4j config (i.e to log4j.xml or log4j.properties), If you are using log4j xml config you can do some thing like this

<category name="org.springframework.beans">
    <priority value="debug" />
</category>

or

<category name="org.springframework">
    <priority value="debug" />
</category>

I would advise you to test this problem in isolation using JUnit test, You can do this by using spring testing module in conjunction with Junit. If you use spring test module it will do the bulk of the work for you it loads context file based on your context config and starts container so you can just focus on testing your business logic. I have a small example here

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:springContext.xml"})
@Transactional
public class SpringDAOTest 
{
    @Autowired
    private SpringDAO dao;

    @Autowired
    private ApplicationContext appContext;

    @Test
    public void checkConfig()
    {
        AnySpringBean bean =  appContext.getBean(AnySpringBean.class);
        Assert.assertNotNull(bean);
    }
}

UPDATE

I am not advising you to change the way you load logging but try this in your dev environment, Add this snippet to your web.xml file

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/log4j.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

UPDATE log4j config file

I tested this on my local tomcat and it generated a lot of logging on application start up. I also want to make a correction: use debug not info as @Rayan Stewart mentioned.

Iterate every 15 minutes

DateTime startDate = DateTime.Parse("2018-06-24 06:00");
        DateTime endDate = DateTime.Parse("2018-06-24 11:45");

        while (startDate.AddMinutes(15) <= endDate)
        {

            Console.WriteLine(startDate.ToString("yyyy-MM-dd HH:mm"));
            startDate = startDate.AddMinutes(15);
        }

git reset --hard
git clean -fd

This worked for me - clean showed all the files it deleted too. If it tells you you'll lose changes, you need to stash.

You'd use REGEXP_REPLACE in order to remove all non-digit characters from a string:

select regexp_replace(column_name, '[^0-9]', '')
from mytable;

or

select regexp_replace(column_name, '[^[:digit:]]', '')
from mytable;

Of course you can write a function extract_number. It seems a bit like overkill though, to write a funtion that consists of only one function call itself.

create function extract_number(in_number varchar2) return varchar2 is
begin
  return regexp_replace(in_number, '[^[:digit:]]', '');
end; 

There is a fairly simple answer with powershell.

Import-PfxCertificate -Password $secure_pw  -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx

The trick is making a "secure" password...

$plaintext_pw = 'PASSWORD';
$secure_pw = ConvertTo-SecureString $plaintext_pw -AsPlainText -Force; 
Import-PfxCertificate -Password $secure_pw  -CertStoreLocation Cert:\LocalMachine\Root -FilePath certs.pfx;

Might be worth checking the config file in the .git folder. If the heroku parameters are missing then you´ll get this error heroku param

[remote "heroku"]
    url = [email protected]:`[Your heroku app].git
    fetch = +refs/heads/*:refs/remotes/heroku/*

the .git folder should be in the local computer file directory for the app you created in heroku. e.g C:\Users\You\Your app.git

Hope this helps

Here's the link that gives me the answer:

[Install] the "fake sendmail for windows". If you are not using XAMPP you can download it here: http://glob.com.au/sendmail/sendmail.zip

[Modify] the php.ini file to use it (commented out the other lines):

[mail function]
; For Win32 only.
; SMTP = smtp.gmail.com
; smtp_port = 25

; For Win32 only.
; sendmail_from = <e-mail username>@gmail.com

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(ignore the "Unix only" bit, since we actually are using sendmail)

You then have to configure the "sendmail.ini" file in the directory where sendmail was installed:

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=<username>
auth_password=<password>
force_sender=<e-mail username>@gmail.com

To access a Gmail account protected by 2-factor verification, you will need to create an application-specific password. (source)

I don't know why this answer hasn't already been given:

Different callers of the same library will, in general, use different configurations. This implies that the configuration must reside in the executable application, and not in the class library.

You may create an app.config within the class library project. It will contain default configurations for items you create within the library. For instance, it will contain connection strings if you create an Entity Framework model within the class library.

However, these settings will not be used by the executable application calling the library. Instead, these settings may be copied from the library.dll.config file into the app.config or web.config of the caller, so that they may be changed to be specific to the caller, and to the environment into which the caller is deployed.

This is how it has been with .NET since Day 1.

Try this or purpose will solve with lesser no of steps

for (int i = 0; i < a.length; i++) 
{
    for (int k = i+1; k < a.length; k++)

        if (a[i] != a[k]) 
         {
            System.out.println(a[i]+"not the same with"+a[k]+"\n");
        }
    }
}

With so many great answers, I thought I would toss one more into the mix. This one, unlike the others, would permit you to cycle through any number of messages with ease:

var index = 0,
    messg = [
        "PUSH ME", 
        "DON'T PUSH ME", 
        "I'M SO CONFUSED!"
    ];

$(".pushme").on("click", function() {
    $(this).text(function(index, text){
        index = $.inArray(text, messg);
        return messg[++index % messg.length];
    });
}??????????????????????????????????????????????);?

You can do it like this:

function fillArray(value, len) {
  if (len == 0) return [];
  var a = [value];
  while (a.length * 2 <= len) a = a.concat(a);
  if (a.length < len) a = a.concat(a.slice(0, len - a.length));
  return a;
}

It doubles the array in each iteration, so it can create a really large array with few iterations.

Note: You can also improve your function a lot by using push instead of concat, as concat will create a new array each iteration. Like this (shown just as an example of how you can work with arrays):

function fillArray(value, len) {
  var arr = [];
  for (var i = 0; i < len; i++) {
    arr.push(value);
  }
  return arr;
}

Just in case. Make sure you load the IE specific js files after you load your css files.

or, we can use something like this

dim i = dgv1.CurrentCellAddress.X
dim j = dgv1.CurrentCellAddress.Y
MsgBox(dgv1.Item(i,j).Value.ToString())

Perhaps you'd consider using android:shadowColor, android:shadowDx, android:shadowDy, android:shadowRadius; alternatively setShadowLayer() ?

For checking existence one can also use (works for both, files and folders):

Not Dir(DirFile, vbDirectory) = vbNullString

_{The result is True if a file or a directory exists.}

Example:

If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then
    MsgBox "exists"
Else
    MsgBox "does not exist"
End If

I encountered this error when I had a row.names="id" (per the tutorial) with a column named "id".

Another way to do it that hasn't been mentioned yet is the tolist method:

myseries.tolist().index(7)

should return the correct index, assuming the value exists in the Series.

Can you not just loop through the sheets from 0 to Count of names -1? that way you should get them in the correct order.

Edit

I noticed through the comments that there are a lot of concerns about using the Interop classes to retrieve the sheet names. Therefore here is an example using OLEDB to retrieve them:

/// <summary>
/// This method retrieves the excel sheet names from 
/// an excel workbook.
/// </summary>
/// <param name="excelFile">The excel file.</param>
/// <returns>String[]</returns>
private String[] GetExcelSheetNames(string excelFile)
{
    OleDbConnection objConn = null;
    System.Data.DataTable dt = null;

    try
    {
        // Connection String. Change the excel file to the file you
        // will search.
        String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" + 
          "Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";
        // Create connection object by using the preceding connection string.
        objConn = new OleDbConnection(connString);
        // Open connection with the database.
        objConn.Open();
        // Get the data table containg the schema guid.
        dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

        if(dt == null)
        {
           return null;
        }

        String[] excelSheets = new String[dt.Rows.Count];
        int i = 0;

        // Add the sheet name to the string array.
        foreach(DataRow row in dt.Rows)
        {
           excelSheets[i] = row["TABLE_NAME"].ToString();
           i++;
        }

        // Loop through all of the sheets if you want too...
        for(int j=0; j < excelSheets.Length; j++)
        {
            // Query each excel sheet.
        }

        return excelSheets;
   }
   catch(Exception ex)
   {
       return null;
   }
   finally
   {
      // Clean up.
      if(objConn != null)
      {
          objConn.Close();
          objConn.Dispose();
      }
      if(dt != null)
      {
          dt.Dispose();
      }
   }
}

The drawback of Contains method is that it doesn't allow to specify comparison type which is often important when comparing strings. It is always culture-sensitive and case-sensitive. So I think the answer of WhoIsRich is valuable, I just want to show a simpler alternative:

listOfStrings.Any(s => s.Equals(myString, StringComparison.OrdinalIgnoreCase))

You can use a generator expression:

tuple(i for i in (1, 2, 3))

but parentheses were already taken for … generator expressions.

neither try any above ways nor sudo apt autoremove python3 because it will remove all gnome based applications from your system including gnome-terminal. In case if you have done that mistake and left with kernal only than trysudo apt install gnome on kernal.

try to change your default python version instead removing it. you can do this through bashrc file or export path command.

First of all, there's no such thing as a JSON object. What you've got in your question is a JavaScript object literal (see here for a great discussion on the difference). Here's how you would go about serializing what you've got to JSON though:

I would use an anonymous type filled with your results type:

string json = JsonConvert.SerializeObject(new
{
    results = new List<Result>()
    {
        new Result { id = 1, value = "ABC", info = "ABC" },
        new Result { id = 2, value = "JKL", info = "JKL" }
    }
});

Also, note that the generated JSON has result items with ids of type Number instead of strings. I doubt this will be a problem, but it would be easy enough to change the type of id to string in the C#.

I'd also tweak your results type and get rid of the backing fields:

public class Result
{
    public int id { get ;set; }
    public string value { get; set; }
    public string info { get; set; }
}

Furthermore, classes conventionally are PascalCased and not camelCased.

Here's the generated JSON from the code above:

{
  "results": [
    {
      "id": 1,
      "value": "ABC",
      "info": "ABC"
    },
    {
      "id": 2,
      "value": "JKL",
      "info": "JKL"
    }
  ]
}

On Linux to get a list of fonts (and their names which you have to use) run this in another shell:

fc-list | awk '{$1=""}1' | cut -d: -f1 | sort| uniq

You can specify a list of fonts, to have fallback values in case a font is missing.

You can't use curlies (moustache tags) in attributes. Use the following to concat data:

<img v-bind:src="imgPreUrl + 'img/logo.png'">

Or the short version:

<img :src="imgPreUrl + 'img/logo.png'">

Read more on dynamic attributes in the Vue docs.

Simplest way is probably to just use Zend Framework or any of the other frameworks like CakePHP or Symphony.

You can do it with the standard mail function too, but you'll need a bit more knowledge on how to attach pictures.

Alternatively, just host the images on a server instead of attaching them. Sending HTML mail is documented in the mail function documentation.

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

The best solution I have found (to an otherwise frustrating problem that should have been solved in the framework) is similar to vaychick's.

Just set number of lines to 0 in either IB or code

myLabel.numberOfLines = 0;

This will display the lines needed but will reposition the label so its centered horizontally (so that a 1 line and 3 line label are aligned in their horizontal position). To fix that add:

CGRect currentFrame = myLabel.frame;
CGSize max = CGSizeMake(myLabel.frame.size.width, 500);
CGSize expected = [myString sizeWithFont:myLabel.font constrainedToSize:max lineBreakMode:myLabel.lineBreakMode]; 
currentFrame.size.height = expected.height;
myLabel.frame = currentFrame;

One liner:

total_line_count = sum(1 for line in open("filename.txt"))

print(total_line_count)

Standing on the shoulders of @ChrisJohnson, I extended the answer from Feb 2016 with a custom dialect for reading. This shell pipeline tool does not need to connect to your database, handles random commas and quotes in the input, and works nicely in Python2 and Python3!

#!/usr/bin/env python
import csv
import sys
# fields are separated by tabs; double-quotes may occur anywhere
csv.register_dialect("mysql", delimiter="\t", quoting=csv.QUOTE_NONE)
tab_in = csv.reader(sys.stdin, dialect="mysql")
comma_out = csv.writer(sys.stdout, dialect=csv.excel)
for row in tab_in:
    # print("row: {}".format(row))
    comma_out.writerow(row)

Use that print statement to convince yourself it's parsing your input correctly :)

A major caveat: treatment of carriage return characters, ^M aka control-M, \r in linux terms. Altho batch-mode Mysql output correctly escapes embedded newline characters, so there is truly one row per line (defined by linux newline character \n), mysql puts no quotes around column data. If a data item has an embedded carriage-return character, csv.reader rejects that input with this exception:

new-line character seen in unquoted field - 
do you need to open the file in universal-newline mode?

Please don't @ me saying I should use universal file mode by re-opening sys.stdin.fileno with mode 'rU'. I tried that, it causes the embedded \r characters to be treated as end-of-record markers, so a single input record is incorrectly transformed into many incomplete output records. I have not found a Python solution to this limitation of Python's csv.reader module. I think the root cause is the csv.reader implementation/limitation noted in their documentation https://docs.python.org/3/library/csv.html#csv.reader:

The reader is hard-coded to recognise either '\r' or '\n' as end-of-line,
and ignores lineterminator.

The weak & unsatisfying solution I can offer is to change each \r character to the two-character sequence '\n' before Python's csv.reader sees the data. I used the sed command. Here's an example of a pipeline with a mysql select and the python script from above:

mysql -u user db --execute="select * from table where id=12345" \
  | sed -e 's/\r/\\n/g' \
  | mysqlTsvToCsv.py

After fighting this for some time I think Python is not the right solution. If you can live with perl, I think the one-liner script offered by @artfulrobot may be the most-effective and simplest solution.

1. 1 += 2 won't throw an error but you still shouldn't do it. In this statement you are basically saying "set 1 equal to 1 + 2" but 1 is a constant number and not a variable of type :number or :string so it probably wouldn't do anything. Saying

   var myVariable = 1
   myVariable += 2
   console.log(myVariable)
   

   would log 3 to the console, as x += y is just short for x = x + y

2. var data = [1,2,3,4,5]
   var sum
   data.forEach(function(value){
     sum += value
   })
   

   would make sum = 15 because:

   sum += 1 //sum = 1
   sum += 2 //sum = 3
   sum += 3 //sum = 6
   sum += 4 //sum = 10
   sum += 5 //sum = 15
   

If you're just after console logging here's what I'd do:

export default class App extends Component {
  componentDidMount() {
    console.log('I was triggered during componentDidMount')
  }

  render() {
    console.log('I was triggered during render')
    return ( 
      <div> I am the App component </div>
    )
  }
}

Shouldn't be any need for those packages just to do console logging.

Better solution is to use NZ (null to zero) function during generating table => NZ([ColumnName]) It comes 0 where is "null" in ColumnName.

I believe the solution by @slipset was correct, but wasn't cross-browser ready.

According to Javascript.info, events (when referenced outside markup events) are cross-browser ready once you assure it's defined with this simple line: event = event || window.event.

So the complete cross-browser ready function would look like this:

function doSomething(param){
  event = event || window.event;
  var source = event.target || event.srcElement;
  console.log(source);
}

Check your file name in which you have saved your program. If the file name is wordlists then you will get an error. Your filename should not be same as any of methods{functions} that you use in your program.

Install redis on your system first -

You'll need to check the contents of $_POST["JSONfullInfoArray"]. If something doesn't parse json_decode will just return null. This isn't very helpful so when null is returned you should check json_last_error() to get more info on what went wrong.

Apply float:left; to both of your divs should make them stand side by side.

Swift 3:

let tapGestureRecognizer: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTapGestureRecognizer(_:)))
view.addGestureRecognizer(tapGestureRecognizer)

func handleTapGestureRecognizer(_ gestureRecognizer: UITapGestureRecognizer) {

}

I think a for-loop should be a valid solution :

    public int getIndexByname(String pName)
    {
        for(AuctionItem _item : *yourArray*)
        {
            if(_item.getName().equals(pName))
                return *yourarray*.indexOf(_item)
        }
        return -1;
    }

For small numbers n%3 == 0 will be fine. For very large numbers I propose to calculate the cross sum first and then check if the cross sum is a multiple of 3:

def is_divisible_by_3(number):
    if sum(map(int, str(number))) % 3 != 0:
        my_bool = False
    return my_bool

Given that the Apache Subversion server will be moved to this new DNS alias: sub.someaddress.com.tr:

• With Subversion 1.7 or higher, use svn relocate. Relocate is used when the SVN server's location changes. switch is only used if you want to change your local working copy to another branch or another path. If using TortoiseSVN, you may follow instructions from the TortoiseSVN Manual. If using the SVN command line interface, refer to this section of SVN's documentation. The command should look like this:

  svn relocate svn://sub.someaddress.com.tr/project

• Keep using /project given that the actual contents of your repository probably won't change.

Note: svn relocate is not available before version 1.7 (thanks to ColinM for the info). In older versions you would use:

    svn switch --relocate OLD NEW

We draw a solid line if and only if we have an ID-dependent relationship; otherwise it would be a dashed line.

Consider a weak but not ID-dependent relationship; We draw a dashed line because it is a weak relationship.

Yes, I'm answering my own question, but I haven't found it here yet and thought this was a rather slick thing:

...in VB.NET:

String.Join(",", CType(TargetArrayList.ToArray(Type.GetType("System.String")), String()))

...in C#

string.Join(",", (string[])TargetArrayList.ToArray(Type.GetType("System.String")))

The only "gotcha" to these is that the ArrayList must have the items stored as Strings if you're using Option Strict to make sure the conversion takes place properly.

EDIT: If you're using .net 2.0 or above, simply create a List(Of String) type object and you can get what you need with. Many thanks to Joel for bringing this up!

String.Join(",", TargetList.ToArray())

I hunted around for ages to find a decent easy solution to this and in the end found some ridiculously complicated CLR solutions so decided to write my own simple VB one. Simply create a new VB CLR project from the Database tab under Installed Templates, and then add a new SQL CLR VB User Defined Function. I renamed it to CLRGetFilesInDir.vb. Here's the code inside it...

Imports System
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Imports System.IO
-----------------------------------------------------------------------------
Public Class CLRFilesInDir
-----------------------------------------------------------------------------
<SqlFunction(FillRowMethodName:="FillRowFiles", IsDeterministic:=True, IsPrecise:=True, TableDefinition:="FilePath nvarchar(4000)")> _
Public Shared Function GetFiles(PathName As SqlString, Pattern As SqlString) As IEnumerable
    Dim FileNames As String()

    Try
    FileNames = Directory.GetFiles(PathName, Pattern, SearchOption.TopDirectoryOnly)
    Catch
        FileNames = Nothing
    End Try

    Return FileNames

End Function
-----------------------------------------------------------------------------
Public Shared Sub FillRowFiles(ByVal obj As Object, ByRef Val As SqlString)
    Val = CType(obj, String).ToString
End Sub

End Class

I also changed the Assembly Name in the Project Properties window to CLRExcelFiles, and the Default Namespace to CLRGetExcelFiles.

NOTE: Set the target framework to 3.5 if you are using anything less that SQL Server 2012.

Compile the project and then copy the CLRExcelFiles.dll from \bin\release to somewhere like C:\temp on the SQL Server machine, not your own.

In SSMS:-

CREATE ASSEMBLY <your assembly name in here - anything you like>
FROM 'C:\temp\CLRExcelFiles.dll';

CREATE FUNCTION dbo.fnGetFiles
(
@PathName NVARCHAR(MAX),
@Pattern NVARCHAR(MAX)
)
RETURNS TABLE (Val NVARCHAR(100))
AS
EXTERNAL NAME <your assembly name>."CLRGetExcelFiles.CLRFilesInDir".GetFiles;
GO

then call it

SELECT * FROM dbo.fnGetFiles('\\<SERVERNAME>\<$SHARE>\<folder>\' , '*.xls')

NOTE: Even though I changed the Permission Level to EXTERNAL_ACCESS on the SQLCLR tab under Project Properties, I still needed to run this every time I (re)created it.

ALTER ASSEMBLY [CLRFilesInDirAssembly] 
WITH PERMISSION_SET = EXTERNAL_ACCESS 
GO

and wullah! that should work.

It Works

Here are three ways to parse strings into integers, from fastest runtime to slowest:

1. strconv.ParseInt(...) fastest
2. strconv.Atoi(...) still very fast
3. fmt.Sscanf(...) not terribly fast but most flexible

Here's a benchmark that shows usage and example timing for each function:

package main

import "fmt"
import "strconv"
import "testing"

var num = 123456
var numstr = "123456"

func BenchmarkStrconvParseInt(b *testing.B) {
  num64 := int64(num)
  for i := 0; i < b.N; i++ {
    x, err := strconv.ParseInt(numstr, 10, 64)
    if x != num64 || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkAtoi(b *testing.B) {
  for i := 0; i < b.N; i++ {
    x, err := strconv.Atoi(numstr)
    if x != num || err != nil {
      b.Error(err)
    }
  }
}

func BenchmarkFmtSscan(b *testing.B) {
  for i := 0; i < b.N; i++ {
    var x int
    n, err := fmt.Sscanf(numstr, "%d", &x)
    if n != 1 || x != num || err != nil {
      b.Error(err)
    }
  }
}

You can run it by saving as atoi_test.go and running go test -bench=. atoi_test.go.

This solution uses nothing but standard .NET calls.

Tested:

• In use in an enterprise WPF application. Uses async/await to avoid blocking the UI.
• Compatible with .NET 4.5+.
• Tested with no parameters (requires a "GET" behind the scenes).
• Tested with parameters (requires a "POST" behind the scenes).
• Tested with a standard web page such as Google.
• Tested with an internal Java-based webservice.

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web;

private async Task<WebResponse> CallUri(string url, TimeSpan timeout)
{
    var uri = new Uri(url);
    NameValueCollection rawParameters = HttpUtility.ParseQueryString(uri.Query);
    var parameters = new Dictionary<string, string>();
    foreach (string p in rawParameters.Keys)
    {
        parameters[p] = rawParameters[p];
    }

    var client = new HttpClient { Timeout = timeout };
    HttpResponseMessage response;
    if (parameters.Count == 0)
    {
        response = await client.GetAsync(url);
    }
    else
    {
        var content = new FormUrlEncodedContent(parameters);
        string urlMinusParameters = uri.OriginalString.Split('?')[0]; // Parameters always follow the '?' symbol.
        response = await client.PostAsync(urlMinusParameters, content);
    }
    var responseString = await response.Content.ReadAsStringAsync();

    return new WebResponse(response.StatusCode, responseString);
}

private class WebResponse
{
    public WebResponse(HttpStatusCode httpStatusCode, string response)
    {
        this.HttpStatusCode = httpStatusCode;
        this.Response = response;
    }
    public HttpStatusCode HttpStatusCode { get; }
    public string Response { get; }
}

To call with no parameters (uses a "GET" behind the scenes):

 var timeout = TimeSpan.FromSeconds(300);
 WebResponse response = await this.CallUri("http://www.google.com/", timeout);
 if (response.HttpStatusCode == HttpStatusCode.OK)
 {
     Console.Write(response.Response); // Print HTML.
 }

To call with parameters (uses a "POST" behind the scenes):

 var timeout = TimeSpan.FromSeconds(300);
 WebResponse response = await this.CallUri("http://example.com/path/to/page?name=ferret&color=purple", timeout);
 if (response.HttpStatusCode == HttpStatusCode.OK)
 {
     Console.Write(response.Response); // Print HTML.
 }

I think what you might be after (as a literal implementation of your question), is:

public class TokenTree
{
    public TokenTree()
    {
        tree = new Dictionary<string, IDictionary<string,string>>();
    }

    IDictionary<string, IDictionary<string, string>> tree; 
}

You did actually say a "list" of key-values in your question, so you might want to swap the inner IDictionary with a:

IList<KeyValuePair<string, string>>

You can do it like this:

CREATE TABLE mytable (
field1 text,
field2 text,
field3 integer,
PRIMARY KEY (field1, field2)
);

For muting library("name_of_library") codes, meanly just showing the codes, {r loadlib, echo=T, results='hide', message=F, warning=F} is great. And imho a better way than library(package, warn.conflicts=F, quietly=T)

It's worth investigating the Pipeline plugin. With the plugin you can checkout multiple VCS projects into relative directory paths. Beforehand creating a directory per VCS checkout. Then issue commands to the newly checked out VCS workspace. In my case I am using git. But you should get the idea.

node{
    def exists = fileExists 'foo'
    if (!exists){
        new File('foo').mkdir()
    }
    dir ('foo') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'bar'
    if (!exists){
        new File('bar').mkdir()
    }
    dir ('bar') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'baz'
    if (!exists){
        new File('baz').mkdir()
    }
    dir ('baz') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
}

Let's suppose you want to find all int not preceded by unsigned:

With support for negative look-behind:

(?<!unsigned )int

Without support for negative look-behind:

((?!unsigned ).{9}|^.{0,8})int

Basically idea is to grab n preceding characters and exclude match with negative look-ahead, but also match the cases where there's no preceeding n characters. (where n is length of look-behind).

So the regex in question:

(?<!filename)\.js$

would translate to:

((?!filename).{8}|^.{0,7})\.js$

You might need to play with capturing groups to find exact spot of the string that interests you or you want't to replace specific part with something else.

you can simply do this :

$ echo $(cat input) > output

you can do:

adb pull /storage/emulated/0/Android/data//

Usually i prefer like below in swift 3, because i can add file name and create a file easily

let fileManager = FileManager.default
if let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first {
    let databasePath = documentsURL.appendingPathComponent("db.sqlite3").path
    print("directory path:", documentsURL.path)
    print("database path:", databasePath)
    if !fileManager.fileExists(atPath: databasePath) {
        fileManager.createFile(atPath: databasePath, contents: nil, attributes: nil)
    }
}

What kind of problem do you get with jregex? It worked well for me under java5 and java6.

Jregex does the job well (even if the last version is from 2002), unless you want to wait for javaSE 7.

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?
