1. Go to the IIS Manager.
2. open the server name like (PC-Name)\.
3. then double click on the ISAPI and CGI Restriction.
4. then select ASP.NET v4.0.30319(32-bit) Restriction allowed.

$(".list-toggle").click(function() {
    $(this).hasAttr('colspan') ? 
        $(this).removeAttr('colspan') : $(this).attr('colspan', 6);
});

there you go.

private void YurTextBox_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            YourButton_Click(this, new EventArgs());
        }
    }

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

The information I give here is not new, I just added this for completeness.

The idea of this code is quite simple:

• Objects need a unique ID, which isn't there by default. Instead, we have to rely on the next best thing, which is RuntimeHelpers.GetHashCode to get us a sort-of unique ID
• To check uniqueness, this implies we need to use object.ReferenceEquals
• However, we would still like to have a unique ID, so I added a GUID, which is by definition unique.
• Because I don't like locking everything if I don't have to, I don't use ConditionalWeakTable.

Combined, that will give you the following code:

public class UniqueIdMapper
{
    private class ObjectEqualityComparer : IEqualityComparer<object>
    {
        public bool Equals(object x, object y)
        {
            return object.ReferenceEquals(x, y);
        }

        public int GetHashCode(object obj)
        {
            return RuntimeHelpers.GetHashCode(obj);
        }
    }

    private Dictionary<object, Guid> dict = new Dictionary<object, Guid>(new ObjectEqualityComparer());
    public Guid GetUniqueId(object o)
    {
        Guid id;
        if (!dict.TryGetValue(o, out id))
        {
            id = Guid.NewGuid();
            dict.Add(o, id);
        }
        return id;
    }
}

To use it, create an instance of the UniqueIdMapper and use the GUID's it returns for the objects.

Addendum

So, there's a bit more going on here; let me write a bit down about ConditionalWeakTable.

ConditionalWeakTable does a couple of things. The most important thing is that it doens't care about the garbage collector, that is: the objects that you reference in this table will be collected regardless. If you lookup an object, it basically works the same as the dictionary above.

Curious no? After all, when an object is being collected by the GC, it checks if there are references to the object, and if there are, it collects them. So if there's an object from the ConditionalWeakTable, why will the referenced object be collected then?

ConditionalWeakTable uses a small trick, which some other .NET structures also use: instead of storing a reference to the object, it actually stores an IntPtr. Because that's not a real reference, the object can be collected.

So, at this point there are 2 problems to address. First, objects can be moved on the heap, so what will we use as IntPtr? And second, how do we know that objects have an active reference?

• The object can be pinned on the heap, and its real pointer can be stored. When the GC hits the object for removal, it unpins it and collects it. However, that would mean we get a pinned resource, which isn't a good idea if you have a lot of objects (due to memory fragmentation issues). This is probably not how it works.
• When the GC moves an object, it calls back, which can then update the references. This might be how it's implemented judging by the external calls in DependentHandle - but I believe it's slightly more sophisticated.
• Not the pointer to the object itself, but a pointer in the list of all objects from the GC is stored. The IntPtr is either an index or a pointer in this list. The list only changes when an object changes generations, at which point a simple callback can update the pointers. If you remember how Mark & Sweep works, this makes more sense. There's no pinning, and removal is as it was before. I believe this is how it works in DependentHandle.

This last solution does require that the runtime doesn't re-use the list buckets until they are explicitly freed, and it also requires that all objects are retrieved by a call to the runtime.

If we assume they use this solution, we can also address the second problem. The Mark & Sweep algorithm keeps track of which objects have been collected; as soon as it has been collected, we know at this point. Once the object checks if the object is there, it calls 'Free', which removes the pointer and the list entry. The object is really gone.

One important thing to note at this point is that things go horribly wrong if ConditionalWeakTable is updated in multiple threads and if it isn't thread safe. The result would be a memory leak. This is why all calls in ConditionalWeakTable do a simple 'lock' which ensures this doesn't happen.

Another thing to note is that cleaning up entries has to happen once in a while. While the actual objects will be cleaned up by the GC, the entries are not. This is why ConditionalWeakTable only grows in size. Once it hits a certain limit (determined by collision chance in the hash), it triggers a Resize, which checks if objects have to be cleaned up -- if they do, free is called in the GC process, removing the IntPtr handle.

I believe this is also why DependentHandle is not exposed directly - you don't want to mess with things and get a memory leak as a result. The next best thing for that is a WeakReference (which also stores an IntPtr instead of an object) - but unfortunately doesn't include the 'dependency' aspect.

What remains is for you to toy around with the mechanics, so that you can see the dependency in action. Be sure to start it multiple times and watch the results:

class DependentObject
{
    public class MyKey : IDisposable
    {
        public MyKey(bool iskey)
        {
            this.iskey = iskey;
        }

        private bool disposed = false;
        private bool iskey;

        public void Dispose()
        {
            if (!disposed)
            {
                disposed = true;
                Console.WriteLine("Cleanup {0}", iskey);
            }
        }

        ~MyKey()
        {
            Dispose();
        }
    }

    static void Main(string[] args)
    {
        var dep = new MyKey(true); // also try passing this to cwt.Add

        ConditionalWeakTable<MyKey, MyKey> cwt = new ConditionalWeakTable<MyKey, MyKey>();
        cwt.Add(new MyKey(true), dep); // try doing this 5 times f.ex.

        GC.Collect(GC.MaxGeneration);
        GC.WaitForFullGCComplete();

        Console.WriteLine("Wait");
        Console.ReadLine(); // Put a breakpoint here and inspect cwt to see that the IntPtr is still there
    }

In Linux it is %llu and in Windows it is %I64u

Although I have found it doesn't work in Windows 2000, there seems to be a bug there!

Or, as an alternative to @Chase's code, being a recent plyr fan with a background in databases:

require(plyr)
zz<-join(df1, df2, type="left")
zz[is.na(zz)] <- 0

This is a sample code to take two inputs seperated by split command and delimiter as ","

>>> var1, var2 = input("enter two numbers:").split(',')
>>>enter two numbers:2,3
>>> var1
'2'
>>> var2
'3'

Other variations of delimiters that can be used are as below :
var1, var2 = input("enter two numbers:").split(',')
var1, var2 = input("enter two numbers:").split(';')
var1, var2 = input("enter two numbers:").split('/')
var1, var2 = input("enter two numbers:").split(' ')
var1, var2 = input("enter two numbers:").split('~')

There's your fast method:

For me, the issue was that I have an angular project folder inside a rails project folder, and I ran all the angular update commands in the rails parent folder rather than the actual angular folder.

I ran into the same problem a couple of years ago and funded the development of a plugin to help me in my work. I've released the plugin as open-source so others can benefit from it as well, and you can grab it on Github: https://github.com/eqcss/eqcss

There are a few ways we could apply different responsive styles based on what we can know about an element on the page. Here are a few element queries that the EQCSS plugin will let you write in CSS:

@element 'div' and (condition) {
  $this {
    /* Do something to the 'div' that meets the condition */
  }
  .other {
    /* Also apply this CSS to .other when 'div' meets this condition */
  }
}

So what conditions are supported for responsive styles with EQCSS?

Weight Queries

• min-width in px
• min-width in %
• max-width in px
• max-width in %

Height Queries

• min-height in px
• min-height in %
• max-height in px
• max-height in %

Count Queries

• min-characters
• max-characters
• min-lines
• max-lines
• min-children
• max-children

Special Selectors

Inside EQCSS element queries you can also use three special selectors that allow you to more specifically apply your styles:

• $this (the element(s) matching the query)
• $parent (the parent element(s) of the element(s) matching the query)
• $root (the root element of the document, <html>)

Element queries allow you to compose your layout out of individually responsive design modules, each with a bit of 'self-awareness' of how they are being displayed on the page.

With EQCSS you can design one widget to look good from 150px wide all the way up to 1000px wide, then you can confidently drop that widget into any sidebar in any page using any template (on any site) and

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

The problem seems to be that block elements only scale up to 100% of their containing element, no matter how big their content is—it just overflows. However, making them inline-block elements apparently resizes their width to their actual content.

HTML:

<div id="container">
    <div class="wide">
        foooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
    </div>
    <div class="wide">
        bar
    </div>
</div>

CSS:

.wide { min-width: 100%; display: inline-block; background-color: yellow; }
#container { display: inline-block; }

(The containerelement addresses your follow-up question to make the second div as big as the previous one, and not just the screen width.)

I also set up a JS fiddle showing my demo code.

If you run into any troubles (esp. cross-browser issues) with inline-block, looking at Block-level elements within display: inline-block might help.

get one column in the distinct select and ignore null values:

 var items = db.table.Where(p => p.id!=null).GroupBy(p => p.id)
                                .Select(grp => grp.First().id)
                                .ToList();

In case you are looking for datepicker in spanish (datepicker en español)

<script type="text/javascript">
    $.datepicker.regional['es'] = {
        monthNames: ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'],
        monthNamesShort: ['Ene', 'Feb', 'Mar', 'Abr', 'May', 'Jun', 'Jul', 'Ago', 'Sep', 'Oct', 'Nov', 'Dic'],
        dayNames: ['Domingo', 'Lunes', 'Martes', 'Miercoles', 'Jueves', 'Viernes', 'Sabado'],
        dayNamesShort: ['Dom', 'Lun', 'Mar', 'Mie', 'Jue', 'Vie', 'Sab'],
        dayNamesMin: ['Do', 'Lu', 'Ma', 'Mc', 'Ju', 'Vi', 'Sa']
    }

    $.datepicker.setDefaults($.datepicker.regional['es']);

</script>

This error happens when you have a ViewBag Non-Existent in your razor code calling a method.

Controller

public ActionResult Accept(int id)
{
    return View();
}

razor:

     <div class="col-md-10">
          <input value="@ViewBag.MaximounAmount.ToString()" />@* HERE is the error *@ 
     </div>
</div>

For some reason, the .net aren't able to show the error in the correct line.

Normally this causes a lot of wasted time.

Since the string "North" might be the beginning of a street name, e.g. "Northern Boulevard", street directions are always between the street number and the street name, and separated from street number and street name.

Public Function strReplace(varValue As Variant) as Variant

Select Case varValue

    Case "Avenue"
        strReplace = "Ave"

    Case " North "
        strReplace = " N "

    Case Else
        strReplace = varValue

End Select

End Function

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

I had your code setup on jsFiddle to try diagnose the problem.

As an alternative (if you don't want to use background), you can easily do it by making a view as follows:

<View
    android:layout_width="2dp"
    android:layout_height="match_parent"
    android:background="#000000" />

For having a right border only, place this after the layout (where you want to have the border):

<View
    android:layout_width="2dp"
    android:layout_height="match_parent"
    android:background="#000000" />

For having a left border only, place this before the layout (where you want to have the border):

"Change to if (typeof $next == 'object' && $next.length) $next[0].offsetWidth" -did not help. if you convert Bootstrap 3 to php(for WordPress theme), when adding WP_Query ($loop = new WP_Query( $args );) insert $count = 0;. And and at the end before endwhile; add $count++;.

Here's another method, which happens to use no correlated subqueries or GROUP BY. I'm not expert in PostgreSQL performance tuning, so I suggest you try both this and the solutions given by other folks to see which works better for you.

SELECT l1.*
FROM lives l1 LEFT OUTER JOIN lives l2
  ON (l1.usr_id = l2.usr_id AND (l1.time_stamp < l2.time_stamp 
   OR (l1.time_stamp = l2.time_stamp AND l1.trans_id < l2.trans_id)))
WHERE l2.usr_id IS NULL
ORDER BY l1.usr_id;

I am assuming that trans_id is unique at least over any given value of time_stamp.

I just had this problem, and Google led me here, so just to add to the general solutions here, this is what worked for me:

# 'value' contains the problematic data
unic = u''
unic += value
value = unic

I had this idea after reading Ned's presentation.

I don't claim to fully understand why this works, though. So if anyone can edit this answer or put in a comment to explain, I'll appreciate it.

You could try letting the stream throw an exception on failure:

std::ifstream f;
//prepare f to throw if failbit gets set
std::ios_base::iostate exceptionMask = f.exceptions() | std::ios::failbit;
f.exceptions(exceptionMask);

try {
  f.open(fileName);
}
catch (std::ios_base::failure& e) {
  std::cerr << e.what() << '\n';
}

e.what(), however, does not seem to be very helpful:

• I tried it on Win7, Embarcadero RAD Studio 2010 where it gives "ios_base::failbit set" whereas strerror(errno) gives "No such file or directory."
• On Ubuntu 13.04, gcc 4.7.3 the exception says "basic_ios::clear" (thanks to arne)

If e.what() does not work for you (I don't know what it will tell you about the error, since that's not standardized), try using std::make_error_condition (C++11 only):

catch (std::ios_base::failure& e) {
  if ( e.code() == std::make_error_condition(std::io_errc::stream) )
    std::cerr << "Stream error!\n"; 
  else
    std::cerr << "Unknown failure opening file.\n";
}

You can create a .htaccess file for the folder, wich should have denied access with

Deny from  all

or you can redirect to a custom 404 page

Redirect /includes/ 404.html

If you take a look at the result of valeur <= 0.6, you can see what’s causing this ambiguity:

>>> valeur <= 0.6
array([ True, False, False, False], dtype=bool)

So the result is another array that has in this case 4 boolean values. Now what should the result be? Should the condition be true when one value is true? Should the condition be true only when all values are true?

That’s exactly what numpy.any and numpy.all do. The former requires at least one true value, the latter requires that all values are true:

>>> np.any(valeur <= 0.6)
True
>>> np.all(valeur <= 0.6)
False

Very old but I have just struggled with this, this is how I solved it in pure xml. In res/values/colors.xml I added three colours (the colour_...);

<resources>

    <color name="black_overlay">#66000000</color>

    <color name="colour_highlight_grey">#ff666666</color>
    <color name="colour_dark_blue">#ff000066</color>
    <color name="colour_dark_green">#ff006600</color>

</resources>

In the res/drawable folder I created listview_colours.xml which contained;

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/colour_highlight_grey" android:state_pressed="true"/>
    <item android:drawable="@color/colour_dark_blue" android:state_selected="true"/>
    <item android:drawable="@color/colour_dark_green" android:state_activated="true"/>
    <item android:drawable="@color/colour_dark_blue" android:state_focused="true"/>
</selector>

In the main_activity.xml find the List View and add the drawable to listSelector;

<ListView
    android:id="@+id/menuList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:listSelector="@drawable/listview_colours"
    android:background="#ff222222"/>
</LinearLayout>

Play with the state_... items in the listview_colours.xml to get the effect you want.

There is also a method where you can set the style of the List View but I never managed to get it to work

nBuilder.addAction(android.R.drawable.ic_media_pause,"PAUSE",pendingIntent);

here Notification.Action is not available prior to API 20 and my min version was API 16

You can use isinstance if you have an instance, or issubclass if you have a class. Normally thought its a bad idea. Normally in Python you work out if an object is capable of something by attempting to do that thing to it.

On Linux:

java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

On Mac OSX:

java -XX:+PrintFlagsFinal -version | grep -iE 'heapsize|permsize|threadstacksize'

On Windows:

C:\>java -XX:+PrintFlagsFinal -version | findstr /i "HeapSize PermSize ThreadStackSize"

You can also, if you like use socket id to manage your player list like this.

io.on('connection', function(socket){
  socket.on('disconnect', function() {
    console.log("disconnect")
    for(var i = 0; i < onlineplayers.length; i++ ){
      if(onlineplayers[i].socket === socket.id){
        console.log(onlineplayers[i].code + " just disconnected")
        onlineplayers.splice(i, 1)
      }
    }
    io.emit('players', onlineplayers)
  })

  socket.on('lobby_join', function(player) {
    if(player.available === false) return
    var exists = false
    for(var i = 0; i < onlineplayers.length; i++ ){
      if(onlineplayers[i].code === player.code){
        exists = true
      }
    }
    if(exists === false){
      onlineplayers.push({
        code: player.code,
        socket:socket.id
      })
    }
    io.emit('players', onlineplayers)
  })

  socket.on('lobby_leave', function(player) {
    var exists = false
    for(var i = 0; i < onlineplayers.length; i++ ){
      if(onlineplayers[i].code === player.code){
        onlineplayers.splice(i, 1)
      }
    }
    io.emit('players', onlineplayers)
  })
})

From documentation:

To comply with the SQL standard, IN returns NULL not only if the expression on the left hand side is NULL, but also if no match is found in the list and one of the expressions in the list is NULL.

This is exactly your case.

Both IN and NOT IN return NULL which is not an acceptable condition for WHERE clause.

Rewrite your query as follows:

SELECT  *
FROM    match m
WHERE   NOT EXISTS
        (
        SELECT  1
        FROM    email e
        WHERE   e.id = m.id
        )

Linked lists are preferable over arrays when:

1. you need constant-time insertions/deletions from the list (such as in real-time computing where time predictability is absolutely critical)

2. you don't know how many items will be in the list. With arrays, you may need to re-declare and copy memory if the array grows too big

3. you don't need random access to any elements

4. you want to be able to insert items in the middle of the list (such as a priority queue)

Arrays are preferable when:

1. you need indexed/random access to elements

2. you know the number of elements in the array ahead of time so that you can allocate the correct amount of memory for the array

3. you need speed when iterating through all the elements in sequence. You can use pointer math on the array to access each element, whereas you need to lookup the node based on the pointer for each element in linked list, which may result in page faults which may result in performance hits.

4. memory is a concern. Filled arrays take up less memory than linked lists. Each element in the array is just the data. Each linked list node requires the data as well as one (or more) pointers to the other elements in the linked list.

Array Lists (like those in .Net) give you the benefits of arrays, but dynamically allocate resources for you so that you don't need to worry too much about list size and you can delete items at any index without any effort or re-shuffling elements around. Performance-wise, arraylists are slower than raw arrays.

$(window).unbind('scroll');

Even though the documentation says it will remove all event handlers if called with no arguments, it is worth giving a try explicitly unbinding it.

Update

It worked if you used single quotes? That doesn't sound right - as far as I know, JavaScript treats single and double quotes the same (unlike some other languages like PHP and C).

Google Drive has an extension to open MDB files.

I'm not sure how well BLOBs work because I couldn't get my images to display but all the text came up.

This is from MSDN sample:

(*.bmp, *.jpg)|*.bmp;*.jpg

So for your case

openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"

It does not matter. Both are the same.

C++ Standard Quotes:

If the value of status is zero or EXIT_SUCCESS, an implementation-defined form of the status successful termination is returned.

I do this kind of thing all the time for quick-and-dirty scripts. It's quite common to have a CGI or PHP script that just uses system/popen to call some external program.

Just be extra careful if your web server is open to the internet at large. Be sure to sanitize your GET/POST input in this case so as to not allow attackers to run arbitrary commands on your machine.

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.

If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.

The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.

If I ommit begin - end it is error. So for me this is working (nothing else needed):

set serveroutput on;
begin
DBMS_OUTPUT.PUT_LINE('testing');
end;

Here is a list of sitemap generators (from which obviously you can get the list of URLs from a site): http://code.google.com/p/sitemap-generators/wiki/SitemapGenerators

Web Sitemap Generators

The following are links to tools that generate or maintain files in the XML Sitemaps format, an open standard defined on sitemaps.org and supported by the search engines such as Ask, Google, Microsoft Live Search and Yahoo!. Sitemap files generally contain a collection of URLs on a website along with some meta-data for these URLs. The following tools generally generate "web-type" XML Sitemap and URL-list files (some may also support other formats).

You can use google script which has FREE translate API. All you need is a common google account and do these THREE EASY STEPS.
1) Create new script with such code on google script:

var mock = {
  parameter:{
    q:'hello',
    source:'en',
    target:'fr'
  }
};


function doGet(e) {
  e = e || mock;

  var sourceText = ''
  if (e.parameter.q){
    sourceText = e.parameter.q;
  }

  var sourceLang = '';
  if (e.parameter.source){
    sourceLang = e.parameter.source;
  }

  var targetLang = 'en';
  if (e.parameter.target){
    targetLang = e.parameter.target;
  }

  var translatedText = LanguageApp.translate(sourceText, sourceLang, targetLang, {contentType: 'html'});

  return ContentService.createTextOutput(translatedText).setMimeType(ContentService.MimeType.JSON);
}

2) Click Publish -> Deploy as webapp -> Who has access to the app: Anyone even anonymous -> Deploy. And then copy your web app url, you will need it for calling translate API.

3) Use this java code for testing your API:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class Translator {

    public static void main(String[] args) throws IOException {
        String text = "Hello world!";
        //Translated text: Hallo Welt!
        System.out.println("Translated text: " + translate("en", "de", text));
    }

    private static String translate(String langFrom, String langTo, String text) throws IOException {
        // INSERT YOU URL HERE
        String urlStr = "https://your.google.script.url" +
                "?q=" + URLEncoder.encode(text, "UTF-8") +
                "&target=" + langTo +
                "&source=" + langFrom;
        URL url = new URL(urlStr);
        StringBuilder response = new StringBuilder();
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        con.setRequestProperty("User-Agent", "Mozilla/5.0");
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();
        return response.toString();
    }

}

As it is free, there are QUATA LIMITS: https://docs.google.com/macros/dashboard

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.

Methods like sleep() and wait() of class Thread might throw an InterruptedException. This will happen if some other thread wanted to interrupt the thread that is waiting or sleeping.

Sounds like you want a mirror of the remote repository:

git clone --mirror url://to/remote.git local.git

That command creates a bare repository. If you don't want a bare repository, things get more complicated.

I had same issue before, here is my class which solved color conversions Use it and enjoy :

I got same error after publish my project to my physical server. My web application works perfectly on my computer when I compile on VS2013. When I checked connection string on sql server manager, everything works perfect on server too. I also checked firewall (I switched it off). But still didn't work. I remotely try to connect database by SQL Manager with exactly same user/pass and instance name etc with protocol pipe/tcp and I saw that everything working normally. But when I try to open website I'm getting this error. Is there anyone know 4th option for fix this problem?.

NOTE: My App: ASP.NET 4.5 (by VS2013), Server: Windows 2008 R2 64bit, SQL: MS-SQL WEB 2012 SP1 Also other web applications works great at web browsers with their database on same server.

After one day suffering I found the solution of my issue:

First I checked all the logs and other details but i could find nothing. Suddenly I recognize that; when I try to use connection string which is connecting directly to published DB and run application on my computer by VS2013, I saw that it's connecting another database file. I checked local directories and I found it. ASP.NET Identity not using my connection string as I wrote in web.config file. And because of this VS2013 is creating or connecting a new database with the name "DefaultConnection.mdf" in App_Data folder. Then I found the solution, it was in IdentityModel.cs.

I changed code as this:

public class ApplicationUser : IdentityUser
{
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    //public ApplicationDbContext() : base("DefaultConnection") ---> this was original
    public ApplicationDbContext() : base("<myConnectionStringNameInWebConfigFile>") //--> changed
    {
    }
}

So, after all, I re-builded and published my project and everything works fine now :)

Here's a pure CSS solution, similar to DarkBee's answer, but without the need for an extra .wrapper div:

.dimmed {
  position: relative;
}

.dimmed:after {
  content: " ";
  z-index: 10;
  display: block;
  position: absolute;
  height: 100%;
  top: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.5);
}

I'm using rgba here, but of course you can use other transparency methods if you like.

At the time of writing, none of the answers used a built-in function for this:

function addScheme($url, $scheme = 'http://')
{
  return parse_url($url, PHP_URL_SCHEME) === null ?
    $scheme . $url : $url;
}

echo addScheme('google.com'); // "http://google.com"
echo addScheme('https://google.com'); // "https://google.com"

See also: parse_url()

If you want the quick and dirty way and don't worry about XSS attack, use params.merge to keep previous parameters. e.g.

<%= link_to 'Link', params.merge({:per_page => 20}) %>

see: https://stackoverflow.com/a/4174493/445908

Otherwise , check this answer: params.merge and cross site scripting

Just learning C# and ran across similar situation. but found a solution that I think may help. You may have figured this a long time ago. this will be from starting a new project but you can use it in any.

1) Start new project.

2) go to Project, then New Windows form, then select Windows Form and name Splash.

3) set size, background, text, etc as desired.

4) Under Properties of the Splash.cs form set Start Position: CenterScreen and TopMost: true

5) form1 add "using System.Threading;"

6) form1 under class add "Splash splashscreen = new Splash();"

7) form1 add "splashscreen.Show();" and "Application.DoEvents();"

8) form1 Under Events>>Focus>>Activated add "Thread.Sleep(4000); splashscreen.Close();"

9) Splash.cs add under "Public Splash" add "this.BackColor = Color.Aqua;" /can use any color

10) This is the code for Form1.cs

public partial class Form1 : Form
{
    Splash splashscreen = new Splash();
    public Form1()
    {
        InitializeComponent();
        splashscreen.Show();
        Application.DoEvents();

    }

    private void Form1_Activated(object sender, EventArgs e)
    {
        Thread.Sleep(4000);
        splashscreen.Close();
    }
}

11) this is the code on Splash.cs

public partial class Splash : Form
{
    public Splash()
    {
        InitializeComponent();
        this.BackColor = Color.Aqua;
    }
}

12) I found that if you do NOT do something in the splash then the screen will not stay on the top for the time the first form needs to activate. The Thread count will disappear the splash after x seconds, so your program is normal.

var stringDate = "Sunday, February 28, 2010";

var months = ["January", "February", "March"]; // You add the rest  :-)

var m = /(\w+) (\d+), (\d+)/.exec(stringDate);

var date = new Date(+m[3], months.indexOf(m[1]), +m[2]);

The indexOf method on arrays is only supported on newer browsers (i.e. not IE). You'll need to do the searching yourself or use one of the many libraries that provide the same functionality.

Also the code is lacking any error checking which should be added. (String not matching the regular expression, non existent months, etc.)

You can do this without using refs. This approach is preferred, since refs can lead to fragile code. The React docs advise finding other solutions where possible:

If you have not programmed several apps with React, your first inclination is usually going to be to try to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. Placing the state there often eliminates any desire to use refs to "make things happen" – instead, the data flow will usually accomplish your goal.

Instead, we'll use a state variable to focus the second input field.

1. Add a state variable that we'll pass as a prop to the DescriptionInput:

   initialState() {
     return {
       focusDescriptionInput: false,
     };
   }
   

2. Define a handler method that will set this state variable to true:

   handleTitleInputSubmit() {
     this.setState(focusDescriptionInput: true);
   }
   

3. Upon submitting / hitting enter / next on the TitleInput, we'll call handleTitleInputSubmit. This will set focusDescriptionInput to true.

   <TextInput 
      style = {styles.titleInput}
      returnKeyType = {"next"}
      autoFocus = {true}
      placeholder = "Title" 
      onSubmitEditing={this.handleTitleInputSubmit}
   />
   

4. DescriptionInput's focus prop is set to our focusDescriptionInput state variable. So, when focusDescriptionInput changes (in step 3), DescriptionInput will re-render with focus={true}.

   <TextInput
      style = {styles.descriptionInput}          
      multiline = {true}
      maxLength = {200}
      placeholder = "Description" 
      focus={this.state.focusDescriptionInput}
   />
   

This is a nice way to avoid using refs, since refs can lead to more fragile code :)

EDIT: h/t to @LaneRettig for pointing out that you'll need to wrap the React Native TextInput with some added props & methods to get it to respond to focus:

    // Props:
    static propTypes = { 
        focus: PropTypes.bool,
    } 

    static defaultProps = { 
        focus: false,
    } 

    // Methods:
    focus() {
        this._component.focus(); 
    } 

    componentWillReceiveProps(nextProps) {
        const {focus} = nextProps; 

        focus && this.focus(); 
    }

If you set id in your database to be primary key and autoincrement, then this line of code is wrong:

user.setId(1);

Try with this:

public static void main(String[] args){
         UserBean user = new UserBean();
         user.setUserName("name1");
         user.setPassword("passwd1");
         em.persist(user);
  }

With Cinchoo ETL - an open source library, it can automatically handles columns values containing separators.

Have you checked strncpy?

char * strncpy ( char * destination, const char * source, size_t num );

You must realize that begin and end actually defines a num of bytes to be copied from one place to another.

If you can use range v3 , you can use the reverse range adapter ranges::view::reverse which allows you to view the container in reverse.

A minimal working example:

#include <iostream>
#include <vector>
#include <range/v3/view.hpp>

int main()
{
    std::vector<int> intVec = {1, 2, 3, 4, 5, 6, 7, 8, 9};

    for (auto const& e : ranges::view::reverse(intVec)) {
        std::cout << e << " ";   
    }
    std::cout << std::endl;

    for (auto const& e : intVec) {
        std::cout << e << " ";   
    }
    std::cout << std::endl;
}

See DEMO 1.

Note: As per Eric Niebler, this feature will be available in C++20. This can be used with the <experimental/ranges/range> header. Then the for statement will look like this:

for (auto const& e : view::reverse(intVec)) {
       std::cout << e << " ";   
}

See DEMO 2

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

@Hung Tran's answer works perfect. As an improvement, I would suggest not showing values that are 0. Say you have 5 elements and 2 of them are 0 and rest of them have values, the solution above will show 0 and 0%. It is better to filter that out with a not equal to 0 check!

          var val = dataset.data[i];
          var percent = String(Math.round(val/total*100)) + "%";

          if(val != 0) {
            ctx.fillText(dataset.data[i], model.x + x, model.y + y);
            // Display percent in another line, line break doesn't work for fillText
            ctx.fillText(percent, model.x + x, model.y + y + 15);

I know this is an old post but some further explanation might be useful for someone trying to upload multiple files... Here is what you need to do:

• Input name must be be defined as an array i.e. name="inputName[]"
• Input element must have multiple="multiple" or just multiple
• In your PHP file use the syntax "$_FILES['inputName']['param'][index]"
• Make sure to look for empty file names and paths, the array might contain empty strings. Use array_filter() before count.

Here is a down and dirty example (showing just relevant code)

HTML:

<input name="upload[]" type="file" multiple="multiple" />

PHP:

//$files = array_filter($_FILES['upload']['name']); //something like that to be used before processing files.

// Count # of uploaded files in array
$total = count($_FILES['upload']['name']);

// Loop through each file
for( $i=0 ; $i < $total ; $i++ ) {

  //Get the temp file path
  $tmpFilePath = $_FILES['upload']['tmp_name'][$i];

  //Make sure we have a file path
  if ($tmpFilePath != ""){
    //Setup our new file path
    $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i];

    //Upload the file into the temp dir
    if(move_uploaded_file($tmpFilePath, $newFilePath)) {

      //Handle other code here

    }
  }
}

Hope this helps out!

If you're trying to read XML generated from a URL without file_get_contents() then you'll probably want to have a look at cURL

ManyToManyField isn`t a good choice.You can use some snippets to implement MultipleChoiceField.You can be inspired by MultiSelectField with comma separated values (Field + FormField) But it has some bug in it.And you can install django-multiselectfield.This is more prefect.

if you check for the element type

type(countries[1])

the result will be <class float> so you can use the following code:

[i for i in countries if type(i) is not float]

Do note that if you're adding stuff, you might always want to check that you're not going beyond the limits of int (especially in homework exercises). Also, int main () should return an int.

Using a "do .. while" loop:

#include<iostream>
using namespace std; 
int main () 
{

  int sum = 0;
  int previous = 0;
  int number;
  int numberitems;
  int count = 0;

  cout << "Enter number of items: ";
  cin >> numberitems;

  if ( numberitems <= 0 ) 
  {
    //no request to perform sum
    cout << "Quitting without summing.\n\n";
    return 0;
  }

  do
  {
    cout << "Enter number to add : ";
    cin >> number; 

    sum+=number;

    // check here that the addition didn't break anything.
    // Negative + negative should stay negative, positive + postive should stay positive
    if ((number > 0 && previous > 0 && sum < 0) || (number < 0 && previous < 0 && sum > 0))
    {
      cout << "Error: Beyond int limits !!";
      return 1;
    }

    count++;
    previous = sum;

  }
  while ( count < numberitems);

  cout<<"sum is: "<< sum<<endl;

  return 0;
} 

prefetch_related use for prefetch data for Many to many and many to one relationship data. select_related is to select data from a single value relationship. Both of these are used to fetch data from their relationships from a model. For example, you build a model and a model that has a relationship with other models. When a request comes you will also query for their relationship data and Django has very good mechanisms To access data from their relationship like book.author.name but when you iterate a list of models for fetching their relationship data Django create each request for every single relationship data. To overcome this we do have prefetchd_related and selected_related

Old question, but %l (lower-case L) worked for me in strftime: this may not work for everyone, though, as it's not listed in the Python documentation I found

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

Make a method of MsgBox in your page.

public void MsgBox(String ex, Page pg,Object obj) 
{
    string s = "<SCRIPT language='javascript'>alert('" + ex.Replace("\r\n", "\\n").Replace("'", "") + "'); </SCRIPT>";
    Type cstype = obj.GetType();
    ClientScriptManager cs = pg.ClientScript;
    cs.RegisterClientScriptBlock(cstype, s, s.ToString());
}

and when you want to use msgbox just put this line

MsgBox("! your message !", this.Page, this);

Have you considered using the "xcopy" command?

The xcopy command will do all that for you.

By default, on Linux, Pip installs packages to /usr/local/lib/python2.7/dist-packages.

Using virtualenv or --user during install will change this default location. If you use pip show make sure you are using the right user or else pip may not see the packages you are referencing.

Correct syntax looks like this. See MSDN.

freopen solves the easy part. Keeping old stdin around is not hard if you haven't read anything and if you're willing to use POSIX system calls like dup or dup2. If you're started to read from it, all bets are off.

Maybe you can tell us the context in which this problem occurs?

I'd encourage you to stick to situations where you're willing to abandon old stdin and stdout and can therefore use freopen.

You have to install Python and add it to PATH on Windows. After that you can try:

python `C:/pathToFolder/prog.py`

or go to the files directory and execute:

You need geopy

pip install geopy

and then:

from geopy.geocoders import Nominatim
geolocator = Nominatim()
location = geolocator.reverse("48.8588443, 2.2943506")

print(location.address)

to get more information:

The response is an array.

var_dump($pjs[0]->{'player_name'});

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

Try this:

SELECT  DATEDIFF(dd, 0,GETDATE()) + CONVERT(DATETIME,'03:30:00.000')

I think you misunderstood some core concepts about iOS modal view controllers. When you dismiss VC1, any presented view controllers by VC1 are dismissed as well. Apple intended for modal view controllers to flow in a stacked manner - in your case VC2 is presented by VC1. You are dismissing VC1 as soon as you present VC2 from VC1 so it is a total mess. To achieve what you want, buttonPressedFromVC1 should have the mainVC present VC2 immediately after VC1 dismisses itself. And I think this can be achieved without delegates. Something along the lines:

UIViewController presentingVC = [self presentingViewController];
[self dismissViewControllerAnimated:YES completion:
 ^{
    [presentingVC presentViewController:vc2 animated:YES completion:nil];
 }];

Note that self.presentingViewController is stored in some other variable, because after vc1 dismisses itself, you shouldn't make any references to it.

You could also check if the id element is used by doing so:

if(typeof $(.div).attr('id') == undefined){
   //element has no id
} else {
   //element has id selector
}

I use this method for global dataTables and specific ordered dataTables

You cannot have snapshot isolation and blocking reads at the same time. The purpose of snapshot isolation is to prevent blocking reads.

Retrieve informations from image elements on the page

If you want to get values in Javascript on frontend, you can use the native way to do it by using :

document.getElementsByName("movie")[0].value;

Where "movie" is the name of your input <input type="text" name="movie">

If you want to get it on angular.js controller, you can use;

$scope.movie

You can use the following CSS to solve.

ul li { float: left; }
ul li:before { content: "|"; padding: 0 .5em; }
ul li:first-child:before { content: ""; padding: 0; }

Should work on IE8+ as well.

Here's also nice way to achieve this via UI.

I have two methods to detect WIFI connection receiving the application context:

1)my old method

public boolean isConnectedWifi1(Context context) {
    try {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();           
        if (networkInfo != null) {
            NetworkInfo[] netInfo = connectivityManager.getAllNetworkInfo();
            for (NetworkInfo ni : netInfo) {
                if ((ni.getTypeName().equalsIgnoreCase("WIFI"))
                        && ni.isConnected()) {
                    return true;
                }                   
            }
        }
        return false;
    } catch (Exception e) {
        Log.e(TAG, e.getMessage());
    }
    return false;
}

2)my New method (I´m currently using this method):

public boolean isConnectedWifi(Context context) {
         ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo networkInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);     
         return networkInfo.isConnected();
}

When there are multiple substrings to remove, one simple and effective option is to use re.sub with a compiled pattern that involves joining all the substrings-to-remove using the regex OR (|) pipe.

import re

to_remove = ['.good', '.bad']
strings = ['Apple.good','Orange.good','Pear.bad']

p = re.compile('|'.join(map(re.escape, to_remove))) # escape to handle metachars
[p.sub('', s) for s in strings]
# ['Apple', 'Orange', 'Pear']

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

1) WebClient is a managed type, so you don't need a finalizer. The finalizer is needed in the case your users don't Dispose() of your NoGateway class and the native type (which is not collected by the GC) needs to be cleaned up after. In this case, if the user doesn't call Dispose(), the contained WebClient will be disposed by the GC right after the NoGateway does.

2) Indirectly yes, but you shouldn't have to worry about it. Your code is correct as stands and you cannot prevent your users from forgetting to Dispose() very easily.

lowercase-with-hyphens is the style I most often see on GitHub.*

lowercase_with_underscores is probably the second most popular style I see.

The former is my preference because it saves keystrokes.

You can manipulate :disabled attribute in vue.js.

It will accept a boolean, if it's true, then the input gets disabled, otherwise it will be enabled...

Something like structured like below in your case for example:

<input type="text" id="name" class="form-control" name="name" v-model="form.name" :disabled="validated ? false : true">

Also read this below:

Conditionally Disabling Input Elements via JavaScript Expression

You can conditionally disable input elements inline with a JavaScript expression. This compact approach provides a quick way to apply simple conditional logic. For example, if you only needed to check the length of the password, you may consider doing something like this.

<h3>Change Your Password</h3>
<div class="form-group">
  <label for="newPassword">Please choose a new password</label>
  <input type="password" class="form-control" id="newPassword" placeholder="Password" v-model="newPassword">
</div>

<div class="form-group">
  <label for="confirmPassword">Please confirm your new password</label>
  <input type="password" class="form-control" id="confirmPassword" placeholder="Password" v-model="confirmPassword" v-bind:disabled="newPassword.length === 0 ? true : false">
</div>

Right-click the title-bar icon of the Explorer window. You'll get the current folder's context menu, where you'll find the "command window here" item.

(Note that to see that menu item, you need to have the corresponding "power toy" installed, or you can create the right registry keys yourself to add that item to folders' context menus.)

I usually do like this:

from numpy import log as ln

Perhaps this can make you more comfortable.

I think the first article you link to states it pretty clearly:

The obvious advantage to writing JavaScript in this manner is that you can use it obscure values that you don't want the user to directly access.

The goal here is to encapsulate and abstract away the fields by only allowing access to them thru a get() or set() method. This way, you can store the field/data internally in whichever way you want, but outside components are only away of your published interface. This allows you to make internal changes without changing external interfaces, to do some validation or error-checking within the set() method, etc.

All of the functionality of our lightweight IDEs can be found within IntelliJ IDEA (you need to install the corresponding plug-ins from the repository).

It includes support for all technologies developed for our more specific products such as Web/PhpStorm, RubyMine and PyCharm.

The specific feature missing from IntelliJ IDEA is simplified project creation ("Open Directory") used in lighter products as it is not applicable to the IDE that support such a wide range of languages and technologies. It also means that you can't create projects directly from the remote hosts in IDEA.

If you are missing any other feature that is available in lighter products, but is not available in IntelliJ IDEA Ultimate, you are welcome to report it and we'll consider adding it.

While PHP, Python and Ruby IDEA plug-ins are built from the same source code as used in PhpStorm, PyCharm and RubyMine, product release cycles are not synchronized. It means that some features may be already available in the lighter products, but not available in IDEA plug-ins at certain periods, they are added with the plug-in and IDEA updates later.

The official way to find out if you have 4.5 installed (and not 4.0) is in the registry keys :

all the other answers of checking the minor version after 4.0.30319.xxxxx seem correct though (msbuild.exe -version , or properties of clr.dll), i just needed something documented (not a blog)

Use the following selector.

$('#attached_docs [value=123]').remove();

Its not possible to hide address bar of browser.

If you want to remove all whitespaces everywhere from $tags why not just:

str_replace(' ', '', $tags);

If you want to remove new lines and such that would require a bit more...

This worked for what I needed it for. The day of month didn't matter in my case because it always happens to be the last day of the month.

public static int MonthDiff(DateTime d1, DateTime d2){
    int retVal = 0;

    if (d1.Month<d2.Month)
    {
        retVal = (d1.Month + 12) - d2.Month;
        retVal += ((d1.Year - 1) - d2.Year)*12;
    }
    else
    {
        retVal = d1.Month - d2.Month;
        retVal += (d1.Year - d2.Year)*12;
    }
    //// Calculate the number of years represented and multiply by 12
    //// Substract the month number from the total
    //// Substract the difference of the second month and 12 from the total
    //retVal = (d1.Year - d2.Year) * 12;
    //retVal = retVal - d1.Month;
    //retVal = retVal - (12 - d2.Month);

    return retVal;
}

Dupe: How do I set an HTML class attribute in Markdown?

Natively? No. But...

No, Markdown's syntax can't. You can set ID values with Markdown Extra through.

You can use regular HTML if you like, and add the attribute markdown="1" to continue markdown-conversion within the HTML element. This requires Markdown Extra though.

<p class='specialParagraph' markdown='1'>
**Another paragraph** which allows *Markdown* within it.
</p>

Possible Solution: (Untested and intended for <blockquote>)

I found the following online:

Function

function _DoBlockQuotes_callback($matches) {

    ...cut...

    //add id and class details...
    $id = $class = '';
    if(preg_match_all('/\{(?:([#.][-_:a-zA-Z0-9 ]+)+)\}/',$bq,$matches)) {
        foreach ($matches[1] as $match) {
            if($match[0]=='#') $type = 'id';
            else $type = 'class';
            ${$type} = ' '.$type.'="'.trim($match,'.# ').'"';
        }
        foreach ($matches[0] as $match) {
            $bq = str_replace($match,'',$bq);
        }
    }

    return _HashBlock(
        "<blockquote{$id}{$class}>\n$bq\n</blockquote>"
    ) . "\n\n";
}

Markdown

>{.className}{#id}This is the blockquote

Result

<blockquote id="id" class="className">
    <p>This is the blockquote</p>
</blockquote>

Your code is in the <head> => runs before the elements are rendered, so document.getElementById('compute'); returns null, as MDN promise...

element = document.getElementById(id);
element is a reference to an Element object, or null if an element with the specified ID is not in the document.

MDN

Solutions:

1. Put the scripts in the bottom of the page.
2. Call the attach code in the load event.
3. Use jQuery library and it's DOM ready event.

What is the jQuery ready event and why is it needed?
(why no just JavaScript's load event):

While JavaScript provides the load event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers...

You can use an alert dialog

    AlertDialog.Builder b = new Builder(this);
    b.setTitle("Example");
    String[] types = {"By Zip", "By Category"};
    b.setItems(types, new OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {

            dialog.dismiss();
            switch(which){
            case 0:
                onZipRequested();
                break;
            case 1:
                onCategoryRequested();
                break;
            }
        }

    });

    b.show();

This will close the dialog when one of them is pressed like you are wanting. Hope this helps!

In the year 2020 / 2021 it is even easier with Array.from to 'convert' from a array-like nodes to an actual array, and then using .map to loop through the resulting array. The code is as simple as the follows:

Array.from(tableFields.children).map((child)=>console.log(child))

I had the same problem, and it was caused by line for insecured registry in: /etc/default/docker

Hardware

I'm sorry, but upgrading development station to SSD and tons of ram has probably a bigger influence than points below combined.

Tools versions

Increasing build performance has major priority for the development teams, so make sure you are using latest Gradle and Android Gradle Plugin.

Configuration File

Create a file named gradle.properties in whatever directory applies:

• /home/<username>/.gradle/ (Linux)
• /Users/<username>/.gradle/ (Mac)
• C:\Users\<username>\.gradle (Windows)

Append:

# IDE (e.g. Android Studio) users:
# Settings specified in this file will override any Gradle settings
# configured through the IDE.

# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html

# The Gradle daemon aims to improve the startup and execution time of Gradle.
# When set to true the Gradle daemon is to run the build.
# TODO: disable daemon on CI, since builds should be clean and reliable on servers
org.gradle.daemon=true

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# https://medium.com/google-developers/faster-android-studio-builds-with-dex-in-process-5988ed8aa37e#.krd1mm27v
org.gradle.jvmargs=-Xmx5120m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
org.gradle.parallel=true

# Enables new incubating mode that makes Gradle selective when configuring projects. 
# Only relevant projects are configured which results in faster builds for large multi-projects.
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
org.gradle.configureondemand=true

# Set to true or false to enable or disable the build cache. 
# If this parameter is not set, the build cache is disabled by default.
# http://tools.android.com/tech-docs/build-cache
android.enableBuildCache=true

Gradle properties works local if you place them at projectRoot\gradle.properties and globally if you place them at user_home\.gradle\gradle.properties. Properties applied if you run gradle tasks from console or directly from idea:

IDE Settings

It is possible to tweak Gradle-IntelliJ integration from the IDE settings GUI. Enabling "offline work" (check answer from yava below) will disable real network requests on every "sync gradle file".

Native multi-dex

One of the slowest steps of the apk build is converting java bytecode into single dex file. Enabling native multidex (minSdk 21 for debug builds only) will help the tooling to reduce an amount of work (check answer from Aksel Willgert below).

Dependencies

Prefer @aar dependencies over library sub-projects.

Search aar package on mavenCentral, jCenter or use jitpack.io to build any library from github. If you are not editing sources of the dependency library you should not build it every time with your project sources.

Antivirus

Consider to exclude project and cache files from antivirus scanning. This is obviously a trade off with security (don't try this at home!). But if you switch between branches a lot, then antivirus will rescan files before allowing gradle process to use it, which slows build time (in particular AndroidStudio sync project with gradle files and indexing tasks). Measure build time and process CPU with and without antivirus enabled to see if it is related.

Profiling a build

Gradle has built-in support for profiling projects. Different projects are using a different combination of plugins and custom scripts. Using --profile will help to find bottlenecks.

If you are using Bearing Token Auth, the above samples do not return an Application User.

Instead, use this:

ClaimsPrincipal currentUser = this.User;
var currentUserName = currentUser.FindFirst(ClaimTypes.NameIdentifier).Value;
ApplicationUser user = await _userManager.FindByNameAsync(currentUserName);

This works in apsnetcore 2.0. Have not tried in earlier versions.

You can use HttpRequestMessagesExtensions.CreateErrorResponse (System.Net.Http namespace), like so:

public IHttpActionResult Get()
{
   return ResponseMessage(Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Message describing the error here"));
}

It is preferable to create responses based on the request to take advantage of Web API's content negotiation.

I found a more recent blog post in Anaconda which instructs how to install the TF easily. I used:

conda create -n tensorflow_env tensorflow

Or for the GPU version (Make sure that you have NVIDIA GPU)

conda create -n tensorflow_gpuenv tensorflow-gpu

This way you will have different environments for different TFs.

I was able to convert string to DWORD and back with this code:

char strAddr[] = "127.0.0.1"
DWORD ip = inet_addr(strAddr); // ip contains 16777343 [0x0100007f in hex]

struct in_addr paddr;
paddr.S_un.S_addr = ip;

char *strAdd2 = inet_ntoa(paddr); // strAdd2 contains the same string as strAdd

I am working in a maintenance project of old MFC code, so converting deprecated functions calls is not applicable.

The easiest way to save the packages from an environment to be installed in another computer is:

$ conda list -e > req.txt

then you can install the environment using

$ conda create -n <environment-name> --file req.txt

if you use pip, please use the following commands: reference https://pip.pypa.io/en/stable/reference/pip_freeze/

$ env1/bin/pip freeze > requirements.txt
$ env2/bin/pip install -r requirements.txt

Best way seems to be the following:

 final LocationManager manager = (LocationManager) getSystemService( Context.LOCATION_SERVICE );

    if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
        buildAlertMessageNoGps();
    }

  private void buildAlertMessageNoGps() {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                   startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
               }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                    dialog.cancel();
               }
           });
    final AlertDialog alert = builder.create();
    alert.show();
}

XCode 12 update:

If you run xcodebuild without -arch param, XCode 12 will build simulator library with architecture "arm64 x86_64" as default.

Then run xcrun -sdk iphoneos lipo -create -output will conflict, because arm64 architecture exist in simulator and also device library.

I fork script from Adam git and fix it.

To have the code within one line, try this:

startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:123456789")));

along with the proper manifest permission:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

Hope this helps!

If you're having trouble with paths you can use

require Rails.root + 'db/migrate/20090408054532_add_foos.rb'

Running git pull performs the following tasks, in order:

1. git fetch
2. git merge

The merge step combines branches that have been setup to be merged in your config. You want to undo the merge step, but probably not the fetch (doesn't make a lot of sense and shouldn't be necessary).

To undo the merge, use git reset --hard to reset the local repository to a previous state; use git-reflog to find the SHA-1 of the previous state and then reset to it.

Warning

The commands listed in this section remove all uncommitted changes, potentially leading to a loss of work:

git reset --hard

Alternatively, reset to a particular point in time, such as:

git reset --hard master@{"10 minutes ago"}

Since I can not comment because of not having enough reward points I have to answer to correct answer given by @Burhan Khalid.
In very layman language Enter key press is combination of carriage return and line feed.
Carriage return points the cursor to the beginning of the line horizontly and Line feed shifts the cursor to the next line vertically.Combination of both gives you new line(\n) effect.
Reference - https://en.wikipedia.org/wiki/Carriage_return#Computers

People gave good answers but forgot to mention the most important part in my opinion: In the second example the X of the list comprehension is NOT the same as the X of the lambda function, they are totally unrelated. So the second example is actually the same as:

[Lambda X: X*X for I in range(10)]

The internal iterations on range(10) are only responsible for creating 10 similar lambda functions in a list (10 separate functions but totally similar - returning the power 2 of each input).

On the other hand, the first example works totally different, because the X of the iterations DO interact with the results, for each iteration the value is X*X so the result would be [0,1,4,9,16,25, 36, 49, 64 ,81]

It's still not possible.

In a strict definition of a boolean element, there are only two values. In a perfect world, that would be true. In the real world, the element may be missing or unknown. Typically, this involves user input. In a screen based system, it could be forced by an edit. In a batch world using either a database or XML input, the element could easily be missing.

So, in the non-perfect world we live in, the Boolean object is great in that it can represent the missing or unknown state as null. After all, computers just model the real world an should account for all possible states and handle them with throwing exceptions (mostly since there are use cases where throwing the exception would be the correct response).

In my case, the Boolean object was the perfect answer since the input XML sometimes had the element missing and I could still get a value, assign it to a Boolean and then check for a null before trying to use a true or false test with it.

Just my 2 cents.

I ran into similar/same error message. In my case, I did not have the target DOM node which is to render the ReactJS component defined. Ensure the HTML target node is well defined with appropriate "id" or "name", along with other HTML attributes (suitable for your design need)

I would use a div to center align an image. As in:

<div align="center"><img src="your_image_source"/></div>

Try the query below:

select count(*),d.dname from emp e , dept d where d.deptno = e.deptno
group by d.dname

K = 32.44
FSPL = Ptx - CLtx + AGtx + AGrx - CLrx - Prx - FM
d = 10 ^ (( FSPL - K - 20 log10( f )) / 20 )

Here:

• K - constant (32.44, when f in MHz and d in km, change to -27.55 when f in MHz and d in m)
• FSPL - Free Space Path Loss
• Ptx - transmitter power, dBm ( up to 20 dBm (100mW) )
• CLtx, CLrx - cable loss at transmitter and receiver, dB ( 0, if no cables )
• AGtx, AGrx - antenna gain at transmitter and receiver, dBi
• Prx - receiver sensitivity, dBm ( down to -100 dBm (0.1pW) )
• FM - fade margin, dB ( more than 14 dB (normal) or more than 22 dB (good))
• f - signal frequency, MHz
• d - distance, m or km (depends on value of K)

Note: there is an error in formulas from TP-Link support site (mising ^).

Substitute Prx with received signal strength to get a distance from WiFi AP.

Example: Ptx = 16 dBm, AGtx = 2 dBi, AGrx = 0, Prx = -51 dBm (received signal strength), CLtx = 0, CLrx = 0, f = 2442 MHz (7'th 802.11bgn channel), FM = 22. Result: FSPL = 47 dB, d = 2.1865 m

Note: FM (fade margin) seems to be irrelevant here, but I'm leaving it because of the original formula.

You should take into acount walls, table http://www.liveport.com/wifi-signal-attenuation may help.

Example: (previous data) + one wooden wall ( 5 dB, from the table ). Result: FSPL = FSPL - 5 dB = 44 dB, d = 1.548 m

Also please note, that antena gain dosn't add power - it describes the shape of radiation pattern (donut in case of omnidirectional antena, zeppelin in case of directional antenna, etc).

None of this takes into account signal reflections (don't have an idea how to do this). Probably noise is also missing. So this math may be good only for rough distance estimation.

Even I was thinking the same. If you open Activity Monitor you can see that it is downloading something at there on the name of GIT.

I found this tip useful.

If you want to remove a specific Item or variable from the user's local storage, you can use

localStorage.removeItem("name of localStorage variable you want to remove");

For Eclipse CDT Kepler what worked for me to get rid of std::thread unresolved symbol is:

1. Go to Preferences->C/C++->Build->Settings

2. Select the Discovery tab

3. Select CDT GCC Built-in Compiler Settings [Shared]

4. Add the -std=c++11 to the "Command to get the compiler specs:" field such as:

${COMMAND} -E -P -v -dD -std=c++11 ${INPUTS}

5. Ok and Rebuild Index for the project.

Adding -std=c++11 to project Properties/C/C++ Build->Settings->Tool Settings->GCC C++ Compiler->Miscellaneous->Other Flags wasn't enough for Kepler, however it was enough for older versions such as Helios.

Move it to the Trusted Sites zone by either adding it to a Trusted Sites list or local setting. This will move it out of Intranet Zone and will not be rendered in Compat. View.

The answer posted to this question as an example taken from Microsoft's MSDN is nice however it doesn't directly demonstrate where the error comes from if it doesn't come from the TRY Block. I prefer this example with a very minor update to the RAISERROR Message within the CATCH Block stating that the error is from the CATCH Block. I demonstrate this in the gif as well.

BEGIN TRY
    /* RAISERROR with severity 11-19 will cause execution
     |  to jump to the CATCH block.
    */
    RAISERROR ('Error raised in TRY block.', -- Message text.
               5, -- Severity. /* Severity Levels Less Than 11 do not jump to the CATCH block */
               1 -- State.
               );
END TRY

BEGIN CATCH
    DECLARE @ErrorMessage  NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState    INT;

    SELECT 
        @ErrorMessage  = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState    = ERROR_STATE();

    /* Use RAISERROR inside the CATCH block to return error
     | information about the original error that caused
     | execution to jump to the CATCH block
    */
    RAISERROR ('Caught Error in Catch', --@ErrorMessage, /* Message text */
               @ErrorSeverity,                           /* Severity     */
               @ErrorState                               /* State        */
               );
END CATCH;

<script>
         arr = []
         arr[0] = "ab"
         arr[1] = "abcdefgh"
         arr[2] = "sdfds"
         arr.sort(function(a,b){
            return a.length<b.length
         })
         document.write(arr)

</script>

The anonymous function that you pass to sort tells it how to sort the given array.hope this helps.I know this is confusing but you can tell the sort function how to sort the elements of the array by passing it a function as a parameter telling it what to do

The better way is using 'background-size'.

.pnx-msg-icon .pnx-icon-msg-warning{
background-image: url("../pics/edit.png");
background-repeat: no-repeat;
background-size: 10px;
width: 10px;
height: 10px;
cursor: pointer;
}

even if your icon dimensions is bigger than 10px it will be 10px.

As mentioned a couple times before: To switch from LinearLayout to RelativeLayout works, but you can also solve the problem instead of avoiding it. Use the tools a LinearLayout provides: Give the TextView a weight=1 (see code below), the weight for your button should remain 0 or none. In this case the TextView will take all the remaining space, which is not used to display the content of your TextView or ButtonView and pushes your button to the right.

<LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_marginTop="35dp">

        <TextView
            android:id="@+id/lblExpenseCancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/cancel"
            android:textColor="#404040"
            android:layout_marginLeft="10dp"
            android:textSize="20sp"
            android:layout_marginTop="9dp"

            **android:layout_weight="1"**

            />

        <Button
            android:id="@+id/btnAddExpense"
            android:layout_width="wrap_content"
            android:layout_height="45dp"
            android:background="@drawable/stitch_button"
            android:layout_marginLeft="10dp"
            android:text="@string/add"
            android:layout_gravity="right"
            android:layout_marginRight="15dp" />

    </LinearLayout>

>>>list(map(int, str(number)))  #number is a given integer

It returns a list of all digits of number.

If you don't have access to DirectoryIterator class try this:

<?php
$path = "/path/to/files";

if ($handle = opendir($path)) {
    while (false !== ($file = readdir($handle))) {
        if ('.' === $file) continue;
        if ('..' === $file) continue;

        // do something with the file
    }
    closedir($handle);
}
?>

A good way is to derive from TcpClient and override the Disposing(bool) method:

class MyClient : TcpClient {
    public bool IsDead { get; set; }
    protected override void Dispose(bool disposing) {
        IsDead = true;
        base.Dispose(disposing);
    }
}

Which won't work if the other code created the instance. Then you'll have to do something desperate like using Reflection to get the value of the private m_CleanedUp member. Or catch the exception.

Frankly, none is this is likely to come to a very good end. You really did want to write to the TCP port. But you won't, that buggy code you can't control is now in control of your code. You've increased the impact of the bug. Talking to the owner of that code and working something out is by far the best solution.

EDIT: A reflection example:

using System.Reflection;
public static bool SocketIsDisposed(Socket s)
{
   BindingFlags bfIsDisposed = BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.GetProperty;
   // Retrieve a FieldInfo instance corresponding to the field
   PropertyInfo field = s.GetType().GetProperty("CleanedUp", bfIsDisposed);
   // Retrieve the value of the field, and cast as necessary
   return (bool)field.GetValue(s, null);
}

To delete all files and directories within the current directory:

find . -mtime +3 | xargs rm -Rf

Or alternatively, more in line with the OP's original command:

find . -mtime +3 -exec rm -Rf -- {} \;

Encapsulation is important in any OO language, popularity has nothing to do with it. In dynamically typed languages, like PHP, it is especially useful because there is little ways to ensure a property is of a specific type without using setters.

In PHP, this works:

class Foo {
   public $bar; // should be an integer
}
$foo = new Foo;
$foo->bar = "string";

In Java, it doesn't:

class Foo {
   public int bar;
}
Foo myFoo = new Foo();
myFoo.bar = "string"; // error

Using magic methods (__get and __set) also works, but only when accessing a property that has lower visibility than the current scope can access. It can easily give you headaches when trying to debug, if it is not used properly.

indexPathForRow is a class method!

The code should read:

NSIndexPath *myIP = [NSIndexPath indexPathForRow:0 inSection:0] ;

use the following line on your DataContext to log the SQL activity on the DataContext to the console - then you can see exactly what your linq statements are requesting from the database:

_db.Log = Console.Out

The following LINQ statements:

var movies = from row in _db.Movies 
             orderby row.CategoryID, row.Name
             select row;

AND

var movies = _db.Movies.OrderBy(m => m.CategoryID).ThenBy(m => m.Name);

produce the following SQL:

SELECT [t0].ID, [t0].[Name], [t0].CategoryID
FROM [dbo].[Movies] as [t0]
ORDER BY [t0].CategoryID, [t0].[Name]

Whereas, repeating an OrderBy in Linq, appears to reverse the resulting SQL output:

var movies = from row in _db.Movies 
             orderby row.CategoryID
             orderby row.Name
             select row;

AND

var movies = _db.Movies.OrderBy(m => m.CategoryID).OrderBy(m => m.Name);

produce the following SQL (Name and CategoryId are switched):

To expand upon Steven Penny's PowerShell solution, you can incorporate it into a batch file by calling powershell.exe like this:

powershell.exe -nologo -noprofile -command "& { Add-Type -A 'System.IO.Compression.FileSystem'; [IO.Compression.ZipFile]::ExtractToDirectory('foo.zip', 'bar'); }"

As Ivan Shilo said, this won't work with PowerShell 2, it requires PowerShell 3 or greater and .NET Framework 4.

You are supposed to import jquery and bootstrap.min.js.

Add this to angular-cli:

"scripts": ["../node_modules/jquery/dist/jquery.min.js",
        "../node_modules/bootstrap/dist/js/bootstrap.min.js"]

make sure you have its folders.

You can use the finish command.

finish: Continue running until just after function in the selected stack frame returns. Print the returned value (if any). This command can be abbreviated as fin.

(See 5.2 Continuing and Stepping.)

I use aggregate along with a vector created by rep(). This has the advantage of using cbind() to aggregate more than 1 column in your dataframe at time. Below is an example of a moving average of 60 for a vector (v) of length 1000:

v=1:1000*0.002+rnorm(1000)
mrng=rep(1:round(length(v)/60+0.5), length.out=length(v), each=60)
aggregate(v~mrng, FUN=mean, na.rm=T)

Note the first argument in rep is to simply get enough unique values for the moving range, based on the length of the vector and the amount to be averaged; the second argument keeps the length equal to the vector length, and the last repeats the values of the first argument the same number of times as the averaging period.

In aggregate you could use several functions (median, max, min) - mean shown for example. Again, could could use a formula with cbind to do this on more than one (or all) columns in a dataframe.

On your remote machine, System.Data.OracleClient need access to some of the oracle dll which are not part of .Net. Solutions:

• Install Oracle Client , and add bin location to Path environment varaible of windows OR
• Copy oraociicus10.dll (Basic-Lite version) or aociei10.dll (Basic version), oci.dll, orannzsbb10.dll and oraocci10.dll from oracle client installable folder to bin folder of application so that application is able to find required dll

On your local machine most probably path to Oracle Client is already added in Path environment variable to there required dll are available to application but not on remote machine

Note : Use it if calculating / adding days from current date.

Be aware: this answer has issues (see comments)

var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);

It should be like

var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));

If they are two integers you can try a quick and dirty trick: Map<String, ?> using the key as i+"#"+j.

If the key i+"#"+j is the same as j+"#"+i try min(i,j)+"#"+max(i,j).

Instead of IN we can use ANY with arrays casted to enum array, for example:

create type example_enum as enum (
  'ENUM1', 'ENUM2'
);

create table example_table (
  id integer,
  enum_field example_enum
);

select 
  * 
from 
  example_table t
where
  t.enum_field = any(array['ENUM1', 'ENUM2']::example_enum[]);

Or we can still use 'IN' clause, but first, we should 'unnest' it:

select 
  * 
from 
  example_table t
where
  t.enum_field in (select unnest(array['ENUM1', 'ENUM2']::example_enum[]));

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

Use strlen to get the length of a null-terminated string.

sizeof returns the length of the array not the string. If it's a pointer (char *s), not an array (char s[]), it won't work, since it will return the size of the pointer (usually 4 bytes on 32-bit systems). I believe an array will be passed or returned as a pointer, so you'd lose the ability to use sizeof to check the size of the array.

So, only if the string spans the entire array (e.g. char s[] = "stuff"), would using sizeof for a statically defined array return what you want (and be faster as it wouldn't need to loop through to find the null-terminator) (if the last character is a null-terminator, you will need to subtract 1). If it doesn't span the entire array, it won't return what you want.

An alternative to all this is actually storing the size of the string.

Instead of putting the listview inside Scrollview, put the rest of the content between listview and the opening of the Scrollview as a separate view and set that view as the header of the listview. So you will finally end up only list view taking charge of Scroll.

By Installing Maven you can not expect the settings.xml in your .m2 folder(If may be hidden folder, to unhide just press Ctrl+h). You need to place the file explicitly at that location. After placing the file maven plugin for eclipse will start using that file too.

Also, if you have a variable,

CabRes::where('m_Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) use ($variable){
          $q->where('Cab', 2)
            ->orWhere('Cab', $variable);
      })
      ->get();

I also had this problem. I changed port and did other things, but they didn't help me. In my case, I connected Tomcat to IDE after installing Netbeans (before). I just uninstalled Netbeans and Tomcat after that I reinstall Netbeans along with Tomcat (NOT separately). And the problem was solved.

Possibly this can be of great help for you.

If I understand your question, here's one way. Say you have:

a = [4.1, 6.21, 1.0]

so here's some code...

def array_in_array(scalarlist):
    return [(x,) for x in scalarlist]

Which leads to:

In [72]: a = [4.1, 6.21, 1.0]

In [73]: a
Out[73]: [4.1, 6.21, 1.0]

In [74]: def array_in_array(scalarlist):
   ....:     return [(x,) for x in scalarlist]
   ....: 

In [75]: b = array_in_array(a)

In [76]: b
Out[76]: [(4.1,), (6.21,), (1.0,)]

Add poster="placeholder.png" to the video tag.

    <source src="video.webm" type="video/webm">
    <object data="video.mp4" width="470" height="255">
    <embed src="video.swf" width="470" height="255">
    </object>
</video>

Does that work?

As an improvement to @Akash Desarda 's answer, you could do

import argparse
from distutils.util import strtobool

parser = argparse.ArgumentParser()
parser.add_argument("--foo", 
    type=lambda x:bool(strtobool(x)),
    nargs='?', const=True, default=False)
args = parser.parse_args()
print(args.foo)

And it supports python test.py --foo

(base) [costa@costa-pc code]$ python test.py
False
(base) [costa@costa-pc code]$ python test.py --foo 
True
(base) [costa@costa-pc code]$ python test.py --foo True
True
(base) [costa@costa-pc code]$ python test.py --foo False
False

A supplementarily handy (but trivial) tip for installing older version of packages from source.

First, if you call "install.packages", it always installs the latest package from repo. If you want to install the older version of packages, say for compatibility, you can call install.packages("url_to_source", repo=NULL, type="source"). For example:

install.packages("http://cran.r-project.org/src/contrib/Archive/RNetLogo/RNetLogo_0.9-6.tar.gz", repo=NULL, type="source")

Without manually downloading packages to the local disk and switching to the command line or installing from local disk, I found it is very convenient and simplify the call (one-step).

Plus: you can use this trick with devtools library's dev_mode, in order to manage different versions of packages:

Reference: doc devtools

I have a computer with 1M of RAM and no other local storage

Another way to cheat: you could use non-local (networked) storage instead (your question does not preclude this) and call a networked service that could use straightforward disk-based mergesort (or just enough RAM to sort in-memory, since you only need to accept 1M numbers), without needing the (admittedly extremely ingenious) solutions already given.

This might be cheating, but it's not clear whether you are looking for a solution to a real-world problem, or a puzzle that invites bending of the rules... if the latter, then a simple cheat may get better results than a complex but "genuine" solution (which as others have pointed out, can only work for compressible inputs).

Preconditions: adb and wireshark is installed on your computer and you have a rooted android device.

1. Download tcpdump to ~/Downloads
2. adb push ~/Downloads/tcpdump /sdcard/
3. adb shell
4. su root
5. mv /sdcard/tcpdump /data/local/
6. cd /data/local/
7. chmod +x tcpdump
8. ./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
9. CTRL+C after you've captured enough packets.
10. exit
11. exit
12. adb pull /sdcard/dump.pcap ~/Downloads/

Now you can open the pcap file using Wireshark.

In oracle an empty varchar2 and null are treated the same, and your observations show that.

when you write:

select * from table where a = '';

its the same as writing

select * from table where a = null;

and not a is null

which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)

To select a device you must first start both, android studio and your virtual device. Then visual studio code will display that virtual device as an option.

If stringArray contains a large number of varied length strings, consider using a Trie to store and search the string array.

public static class Extensions
{
    public static bool ContainsAny(this string stringToCheck, IEnumerable<string> stringArray)
    {
        Trie trie = new Trie(stringArray);
        for (int i = 0; i < stringToCheck.Length; ++i)
        {
            if (trie.MatchesPrefix(stringToCheck.Substring(i)))
            {
                return true;
            }
        }

        return false;
    }
}

Here is the implementation of the Trie class

public class Trie
{
    public Trie(IEnumerable<string> words)
    {
        Root = new Node { Letter = '\0' };
        foreach (string word in words)
        {
            this.Insert(word);
        }
    }

    public bool MatchesPrefix(string sentence)
    {
        if (sentence == null)
        {
            return false;
        }

        Node current = Root;
        foreach (char letter in sentence)
        {
            if (current.Links.ContainsKey(letter))
            {
                current = current.Links[letter];
                if (current.IsWord)
                {
                    return true;
                }
            }
            else
            {
                return false;
            }
        }

        return false;
    }

    private void Insert(string word)
    {
        if (word == null)
        {
            throw new ArgumentNullException();
        }

        Node current = Root;
        foreach (char letter in word)
        {
            if (current.Links.ContainsKey(letter))
            {
                current = current.Links[letter];
            }
            else
            {
                Node newNode = new Node { Letter = letter };
                current.Links.Add(letter, newNode);
                current = newNode;
            }
        }

        current.IsWord = true;
    }

    private class Node
    {
        public char Letter;
        public SortedList<char, Node> Links = new SortedList<char, Node>();
        public bool IsWord;
    }

    private Node Root;
}

If all strings in stringArray have the same length, you will be better off just using a HashSet instead of a Trie

public static bool ContainsAny(this string stringToCheck, IEnumerable<string> stringArray)
{
    int stringLength = stringArray.First().Length;
    HashSet<string> stringSet = new HashSet<string>(stringArray);
    for (int i = 0; i < stringToCheck.Length - stringLength; ++i)
    {
        if (stringSet.Contains(stringToCheck.Substring(i, stringLength)))
        {
            return true;
        }
    }

    return false;
}

The code seems working to me. I think the same with @Iothar.

Check to see if you include the required headers, to compile. If it is compiled, check to see if there is such a file, and everything, names etc, matches, and also check to see that you have a right to read the file.

To make a cross check, check if you can open it with fopen..

FILE *f = fopen("C:/Demo.txt", "r");
if (f)
  printf("fopen success\n");

Your query fails due to operator precedence. AND binds before OR!
You need a pair of parentheses, which is not a matter of "clarity", but pure logic necessity.

SELECT *
FROM   tbl_name
WHERE  other_condition = bar
AND    another_condition = foo
AND   (id_field IN ('value1', 'value2', 'value3') OR id_field IS NULL);

The added parentheses prevent AND binding before OR. If there were no other WHERE conditions (no AND) you would not need additional parentheses. The accepted answer is misleading in this respect.

Set:

Cannot have duplicate values Ordering depends on implementation. By default it is not ordered Cannot have access by index

List:

Can have duplicate values Ordered by default Can have access by index

Documentation Way

This is the recommended way as per the advice given in the Android Studio documentation.

Create a library module

Create a new project to make your library in. Click File > New > New Module > Android Library > Next > (choose name) > Finish. Then add whatever classes and resourced you want to your library.

When you build the module an AAR file will be created. You can find it in project-name/module-name/build/outputs/aar/.

Add your library as a dependency

You can add your library as a dependency to another project like this:

1. Import your library AAR file with File > New Module > Import .JAR/.AAR Package > Next > (choose file location) > Finish. (Don't import the code, otherwise it will be editable in too many places.)

2. In the settings.gradle file, make sure your library name is there.

   include ':app', ':my-library-module'
   

3. In the app's build.gradle file, add the compile line to the dependencies section:

   dependencies {
       compile project(":my-library-module")
   }
   

4. You will be prompted to sync your project with gradle. Do it.

That's it. You should be able to use your library now.

Notes

If you want to make your library easily available to a larger audience, consider using JitPac or JCenter.

I like how this guy does it — https://amalgjose.com/2015/02/19/python-code-for-calculating-the-difference-between-two-time-stamps. Not sure if it has some cons.

But looks neat for me :)

from datetime import datetime
from dateutil.relativedelta import relativedelta

t_a = datetime.now()
t_b = datetime.now()

def diff(t_a, t_b):
    t_diff = relativedelta(t_b, t_a)  # later/end time comes first!
    return '{h}h {m}m {s}s'.format(h=t_diff.hours, m=t_diff.minutes, s=t_diff.seconds)

Regarding to the question you still need to use datetime.strptime() as others said earlier.

You can simply give it as:

System.out.println("Address:" +houseAddress);

Your output will look like [address1, address2, address3]

This is because the class ArrayList or its superclass would have a toString() function overridden.

Hope this helps.

Use adb kill-server. It should helps. or

adb -s emulator-5554 emu kill, where emulator-5554 is the emulator name.

For Ubuntu users I found a good command to stop all running emulators (Thanks to @uwe)

adb devices | grep emulator | cut -f1 | while read line; do adb -s $line emu kill; done

Try this:

// Substitute appropriate type.
ArrayList<...> a = new ArrayList<...>();

// Add elements to list.

// Generate an iterator. Start just after the last element.
ListIterator li = a.listIterator(a.size());

// Iterate in reverse.
while(li.hasPrevious()) {
  System.out.println(li.previous());
}

Using Model:

Model::where('column','value')->get(['column1','column2','column3',...]);

Using Query Builder:

DB::table('table_name')->where('column','value')->get(['column1','column2','column3',...]);

You'll have to strncpy str1 into new_string first then.

I'm surprised not a lot of people know about the download attribute for a elements. Please help spread the word about it! You can have a hidden html link, and fake a click on it. If the html link has the download attribute it downloads the file, not views it, no matter what. Here's the code. It will download a cat picture if it can find it.

document.getElementById('download').click();

<a href="https://docs.google.com/uc?id=0B0jH18Lft7ypSmRjdWg1c082Y2M" download id="download" hidden></a>

Note: This is not supported on all browsers: http://www.w3schools.com/tags/att_a_download.asp

Well, no answers but at least one more test to make. Open Terminal and run this command: "ps-Ael | grep Z". If you get two entries, one "(clang)" and the other your app or company name, you're hosed - reboot.

If you are a developer, enter a short bug and tell Apple how absolutely annoying having to reboot is, and mention they can dup this bug to "rdar://10401934" which I just entered.

ids are unique

• Each element can have only one id
• Each page can have only one element with that id

classes are NOT unique

• You can use the same class on multiple elements.
• You can use multiple classes on the same element.

Javascript cares

JavaScript people are already probably more in tune with the differences between classes and ids. JavaScript depends on there being only one page element with any particular id, or else the commonly used getElementById function couldn't be depended on.
