Programs & Examples On #Virtual pc 2007

As others have explained, var self = this; allows code in a closure to refer back to the parent scope.

However, it's now 2018 and ES6 is widely supported by all major web browsers. The var self = this; idiom isn't quite as essential as it once was.

It's now possible to avoid var self = this; through the use of arrow functions.

In instances where we would have used var self = this:

function test() {
    var self = this;
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", function() {
        console.log(self.hello); // logs "world"
    });
};

We can now use an arrow function without var self = this:

function test() {
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", () => {
        console.log(this.hello); // logs "world"
    });
};

Arrow functions do not have their own this and simply assume the enclosing scope.

Havengard's answer doesn't seem to be strictly true. I've found that vw fills the viewport width, but doesn't account for the scrollbars. So, if your content is taller than the viewport (so that your site has a vertical scrollbar), then using vw results in a small horizontal scrollbar. I had to switch out width: 100vw for width: 100% to get rid of the horizontal scrollbar.

I'm working with SlidingMenu and Fragment, present my case here and hope helps somebody.

Logic when [Back] key pressed :

1. When SlidingMenu shows, close it, no more things to do.
2. Or when 2nd(or more) Fragment showing, slide back to previous Fragment, and no more things to do.

3. SlidingMenu not shows, current Fragment is #0, do the original [Back] key does.

   public class Main extends SherlockFragmentActivity
   {
     private SlidingMenu menu=null;
     Constants.VP=new ViewPager(this);
   
     //Some stuff...
   
     @Override
     public void onBackPressed()
     {
       if(menu.isMenuShowing())
       {
         menu.showContent(true); //Close SlidingMenu when menu showing
         return;
       }
       else
       {
         int page=Constants.VP.getCurrentItem();
         if(page>0)
         {
           Constants.VP.setCurrentItem(page-1, true); //Show previous fragment until Fragment#0
           return;
         }
         else
         {super.onBackPressed();} //If SlidingMenu is not showing and current Fragment is #0, do the original [Back] key does. In my case is exit from APP
       }
     }
   }
   

Use the below command

dir | find "Directory"

Here's a plugin which can list all event handlers for any given element/event:

$.fn.listHandlers = function(events, outputFunction) {
    return this.each(function(i){
        var elem = this,
            dEvents = $(this).data('events');
        if (!dEvents) {return;}
        $.each(dEvents, function(name, handler){
            if((new RegExp('^(' + (events === '*' ? '.+' : events.replace(',','|').replace(/^on/i,'')) + ')$' ,'i')).test(name)) {
               $.each(handler, function(i,handler){
                   outputFunction(elem, '\n' + i + ': [' + name + '] : ' + handler );
               });
           }
        });
    });
};

Use it like this:

// List all onclick handlers of all anchor elements:
$('a').listHandlers('onclick', console.info);

// List all handlers for all events of all elements:
$('*').listHandlers('*', console.info);

// Write a custom output function:
$('#whatever').listHandlers('click',function(element,data){
    $('body').prepend('<br />' + element.nodeName + ': <br /><pre>' + data + '<\/pre>');
});

Ha. Sorry, I mis-read your post. I've used cucumber to test it before. It worked out nicely.

Encode your data string into JSON.

dataString = ??? ; // array?
var jsonString = JSON.stringify(dataString);
   $.ajax({
        type: "POST",
        url: "script.php",
        data: {data : jsonString}, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

In your PHP

$data = json_decode(stripslashes($_POST['data']));

  // here i would like use foreach:

  foreach($data as $d){
     echo $d;
  }

Note

When you send data via POST, it needs to be as a keyvalue pair.

Thus

data: dataString

is wrong. Instead do:

data: {data:dataString}

Standard formats, with their related outputs,

Console.WriteLine("Standard Numeric Format Specifiers");
String s = String.Format("(C) Currency: . . . . . . . . {0:C}\n" +
                    "(D) Decimal:. . . . . . . . . {0:D}\n" +
                    "(E) Scientific: . . . . . . . {1:E}\n" +
                    "(F) Fixed point:. . . . . . . {1:F}\n" +
                    "(G) General:. . . . . . . . . {0:G}\n" +
                    "    (default):. . . . . . . . {0} (default = 'G')\n" +
                    "(N) Number: . . . . . . . . . {0:N}\n" +
                    "(P) Percent:. . . . . . . . . {1:P}\n" +
                    "(R) Round-trip: . . . . . . . {1:R}\n" +
                    "(X) Hexadecimal:. . . . . . . {0:X}\n",
                    - 1234, -1234.565F);
Console.WriteLine(s);

Example output (en-us culture):

(C) Currency: . . . . . . . . ($1,234.00)
(D) Decimal:. . . . . . . . . -1234
(E) Scientific: . . . . . . . -1.234565E+003
(F) Fixed point:. . . . . . . -1234.57
(G) General:. . . . . . . . . -1234
    (default):. . . . . . . . -1234 (default = 'G')
(N) Number: . . . . . . . . . -1,234.00
(P) Percent:. . . . . . . . . -123,456.50 %
(R) Round-trip: . . . . . . . -1234.565
(X) Hexadecimal:. . . . . . . FFFFFB2E

You can change any header or anything in Application_EndRequest() try this

protected void Application_EndRequest()
{
    // removing excessive headers. They don't need to see this.
    Response.Headers.Remove("header_name");
}

those are miliseconds, just divide them by 1000, since gmtime expects seconds ...

time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(1236472051807/1000.0))

Base on lonesomeday's answer, I create a jpost that wraps certain parameters.

$.extend({
    jpost: function(url, body) {
        return $.ajax({
            type: 'POST',
            url: url,
            data: JSON.stringify(body),
            contentType: "application/json",
            dataType: 'json'
        });
    }
});

Usage:

$.jpost('/form/', { name: 'Jonh' }).then(res => {
    console.log(res);
});

Click Insert ->Object->Create from file ->Browse.

Once the file is selected choose the "Change icon" option and you will be able to rename the file and change the icon if you wish.

Hope this helps!

Another example in Kotlin:

override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val binding = DataBindingUtil
            .inflate< MartianDataBinding >(
                    inflater,
                    R.layout.bla,
                    container,
                    false
            )

    binding.modelName = // ..

    return binding.root
}

Note that the name "MartianDataBinding" depends on the name of the layout file. If the file is named "martian_data" then the correct name would be MartianDataBinding.

I often use something similar to this:

import os
DATA_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__), 'datadir'))

# if you have more paths to set, you might want to shorten this as
here = lambda x: os.path.abspath(os.path.join(os.path.dirname(__file__), x))
DATA_DIR = here('datadir') 

pathjoin = os.path.join
# ...
# later in script
for fn in os.listdir(DATA_DIR):
    f = open(pathjoin(DATA_DIR, fn))
    # ...

The variable

__file__

holds the file name of the script you write that code in, so you can make paths relative to script, but still written with absolute paths. It works quite well for several reasons:

• path is absolute, but still relative
• the project can still be deployed in a relative container

But you need to watch for platform compatibility - Windows' os.pathsep is different than UNIX.

found two different solutions which worked in slightly different way:

1. This solution is inspired by the answer from alexanderb [link]. Unfortunately it did not work for us - some dll's were not copied to the OutDir. We found out that replacing ResolveReferences with Build target solves the problem - now all necessary files are copied into the OutDir location.

msbuild /target:Build;_WPPCopyWebApplication  /p:Configuration=Release;OutDir=C:\Tmp\myApp\ MyApp.csproj

2. The first solution works well but not as we expected. We wanted to have the publish functionality as it is in Visual Studio IDE - i.e. only the files which should be published will be copied into the Output directory. As it has been already mentioned first solution copies much more files into the OutDir - the website for publish is then stored in _PublishedWebsites/{ProjectName} subfolder. The following command solves this - only the files for publish will be copied to desired folder. So now you have directory which can be directly published - in comparison with the first solution you will save some space on hard drive.

msbuild /target:Build;PipelinePreDeployCopyAllFilesToOneFolder /p:Configuration=Release;_PackageTempDir=C:\Tmp\myApp\;AutoParameterizationWebConfigConnectionStrings=false MyApp.csproj

I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:

http://css-tricks.com/how-to-resizeable-background-image/

http://css-tricks.com/perfect-full-page-background-image/

Read the descriptions for each of the articles and see if they're what you're looking for.

The first answers the following question:

Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.

The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "

Hope this helps.

var jArr = [
{
    id : "001",
    name : "apple",
    category : "fruit",
    color : "red"
},
{
    id : "002",
    name : "melon",
    category : "fruit",
    color : "green"
},
{
    id : "003",
    name : "banana",
    category : "fruit",
    color : "yellow"
}
]

var tableData = '<table><tr><td>Id</td><td>Name</td><td>Category</td><td>Color</td></tr>';
$.each(jArr, function(index, data) {
 tableData += '<tr><td>'+data.id+'</td><td>'+data.name+'</td><td>'+data.category+'</td><td>'+data.color+'</td></tr>';
});

$('div').html(tableData);

Another dplyr possibility could be:

df %>%
 group_by(cat) %>%
 mutate(num = 1:n())

   cat      val   num
   <fct>  <dbl> <int>
 1 aaa   0.0564     1
 2 aaa   0.258      2
 3 aaa   0.308      3
 4 aaa   0.469      4
 5 aaa   0.552      5
 6 bbb   0.170      1
 7 bbb   0.370      2
 8 bbb   0.484      3
 9 bbb   0.547      4
10 bbb   0.812      5
11 ccc   0.280      1
12 ccc   0.398      2
13 ccc   0.625      3
14 ccc   0.763      4
15 ccc   0.882      5

This seems to be what you're looking for:

g <- ggplot(x, aes(reorder(variable, value), value))
g + geom_bar() + scale_y_continuous(formatter="percent") + coord_flip()

The reorder() function will reorder your x axis items according to the value of variable.

Just Follow this to Insert values into database

//Connection String

  con.Open();

sqlQuery = "INSERT INTO [dbo].[Client] ([Client_ID],[Client_Name],[Phone],[Address],[Image]) VALUES('" + txtClientID.Text + "','" + txtClientName.Text + "','" + txtPhoneno.Text + "','" + txtaddress.Text + "',@image)";

                cmd = new SqlCommand(sqlQuery, con);
                cmd.Parameters.Add("@image", SqlDbType.Image);
                cmd.Parameters["@image"].Value = img;
            //img is a byte object
           ** /*MemoryStream ms = new MemoryStream();
            pictureBox1.Image.Save(ms,pictureBox1.Image.RawFormat);
            byte[] img = ms.ToArray();*/**

                cmd.ExecuteNonQuery();
                con.Close();

Use the FolderExists method of the Scripting object.

Public Function dirExists(s_directory As String) As Boolean
    Dim oFSO As Object
    Set oFSO = CreateObject("Scripting.FileSystemObject")
    dirExists = oFSO.FolderExists(s_directory)
End Function

I used a BoxLayout and set its second parameter as BoxLayout.Y_AXIS and it worked for me:

panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

To set image cource in imageview you can use any of the following ways. First confirm your image is present in which format.

If you have image in the form of bitmap then use

imageview.setImageBitmap(bm);

If you have image in the form of drawable then use

imageview.setImageDrawable(drawable);

If you have image in your resource example if image is present in drawable folder then use

imageview.setImageResource(R.drawable.image);

If you have path of image then use

imageview.setImageURI(Uri.parse("pathofimage"));

I solve this error with the command :

$ sudo chmod 666 /var/run/docker.sock

You've started right - now you just need to fill the each student structure in the array:

struct student
{
    public int s_id;
    public String s_name, c_name, dob;
}
class Program
{
    static void Main(string[] args)
    {
        student[] arr = new student[4];

        for(int i = 0; i < 4; i++)
        {
            Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");


            arr[i].s_id = Int32.Parse(Console.ReadLine());
            arr[i].s_name = Console.ReadLine();
            arr[i].c_name = Console.ReadLine();
            arr[i].s_dob = Console.ReadLine();
       }
    }
}

Now, just iterate once again and write these information to the console. I will let you do that, and I will let you try to make program to take any number of students, and not just 4.

If you use Java 8, you can use chars() on a String to get a Stream of characters, but you will need to cast the int back to a char as chars() returns an IntStream.

"xyz".chars().forEach(i -> System.out.print((char)i));

If you use Java 8 with Eclipse Collections, you can use the CharAdapter class forEach method with a lambda or method reference to iterate over all of the characters in a String.

Strings.asChars("xyz").forEach(c -> System.out.print(c));

This particular example could also use a method reference.

Strings.asChars("xyz").forEach(System.out::print)

Note: I am a committer for Eclipse Collections.

It depends.

When you commit to sending output to stdout, you're basically leaving it up to the user to decide where that output should go.

If you use printf(...) (or the equivalent fprintf(stdout, ...)), you're sending the output to stdout, but where that actually ends up can depend on how I invoke your program.

If I launch your program from my console like this, I'll see output on my console:

$ prog
Hello, World! # <-- output is here on my console

However, I might launch the program like this, producing no output on the console:

$ prog > hello.txt

but I would now have a file "hello.txt" with the text "Hello, World!" inside, thanks to the shell's redirection feature.

Who knows – I might even hook up some other device and the output could go there. The point is that when you decide to print to stdout (e.g. by using printf()), then you won't exactly know where it will go until you see how the process is launched or used.

It's not clear to me what you want, but I'll mention that the Date class also has a compareTo method, which can be used to determine with one call if two Date objects are equal or (if they aren't equal) which occurs sooner. This allows you to do something like:

switch (today.compareTo(questionDate)) {
    case -1:  System.out.println("today is sooner than questionDate");  break;
    case 0:   System.out.println("today and questionDate are equal");  break;
    case 1:   System.out.println("today is later than questionDate");  break;
    default:  System.out.println("Invalid results from date comparison"); break;
}

It should be noted that the API docs don't guarantee the results to be -1, 0, and 1, so you may want to use if-elses rather than a switch in any production code. Also, if the second date is null, you'll get a NullPointerException, so wrapping your code in a try-catch may be useful.

You can deal multipleViewTypes RecyclerAdapter by making getItemViewType() return the expected viewType value for that position

I prepared an MultipleViewTypeAdapter for constructing MCQ list for examinations which may throw a question that may have 2 or more valid answers (checkbox options) and a single answer questions (radiobutton options).

For this i get the type of Question from API response and i used that for deciding which view i have to show for that question .

public class MultiViewTypeAdapter extends RecyclerView.Adapter {

    Context mContext;
    ArrayList<Question> dataSet;
    ArrayList<String> questions;
    private Object radiobuttontype1; 


    //Viewholder to display Questions with checkboxes
    public static class Checkboxtype2 extends RecyclerView.ViewHolder {
        ImageView imgclockcheck;
        CheckBox checkbox;

        public Checkboxtype2(@NonNull View itemView) {
            super(itemView);
            imgclockcheck = (ImageView) itemView.findViewById(R.id.clockout_cbox_image);
            checkbox = (CheckBox) itemView.findViewById(R.id.clockout_cbox);


        }
    }

        //Viewholder to display Questions with radiobuttons

    public static class Radiobuttontype1 extends RecyclerView.ViewHolder {
        ImageView clockout_imageradiobutton;
        RadioButton clockout_radiobutton;
        TextView sample;

        public radiobuttontype1(View itemView) {
            super(itemView);
            clockout_imageradiobutton = (ImageView) itemView.findViewById(R.id.clockout_imageradiobutton);
            clockout_radiobutton = (RadioButton) itemView.findViewById(R.id.clockout_radiobutton);
            sample = (TextView) itemView.findViewById(R.id.sample);
        }
    }

    public MultiViewTypeAdapter(ArrayList<QueDatum> data, Context context) {
        this.dataSet = data;
        this.mContext = context;

    }

    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {

        if (viewType.equalsIgnoreCase("1")) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clockout_radio_list_row, viewGroup, false);
            return new radiobuttontype1(view);

        } else if (viewType.equalsIgnoreCase("2")) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clockout_cbox_list_row, viewGroup, false);
            view.setHorizontalFadingEdgeEnabled(true);
            return new Checkboxtype2(view);

        } else if (viewType.equalsIgnoreCase("3")) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clockout_radio_list_row, viewGroup, false);
            return new Radiobuttontype1(view);

        } else if (viewType.equalsIgnoreCase("4")) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clockout_radio_list_row, viewGroup, false);
            return new Radiobuttontype1(view);

        } else if (viewType.equalsIgnoreCase("5")) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clockout_radio_list_row, viewGroup, false);
            return new Radiobuttontype1(view);
        }


        return null;
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int viewType) {
        if (viewType.equalsIgnoreCase("1")) {
            options =  dataSet.get(i).getOptions();
            question = dataSet.get(i).getQuestion();
            image = options.get(i).getValue();
            ((radiobuttontype1) viewHolder).clockout_radiobutton.setChecked(false);
            ((radiobuttontype1) viewHolder).sample.setText(question);
            //loading image bitmap in the ViewHolder's View
            Picasso.with(mContext)
                    .load(image)
                    .into(((radiobuttontype1) viewHolder).clockout_imageradiobutton);

        } else if (viewType.equalsIgnoreCase("2")) {
            options = (ArrayList<Clockout_questions_Option>) dataSet.get(i).getOptions();
            question = dataSet.get(i).getQuestion();
            image = options.get(i).getValue();
            //loading image bitmap in the ViewHolder's View
            Picasso.with(mContext)
                    .load(image)
                    .into(((Checkboxtype2) viewHolder).imgclockcheck);

        } else if (viewType.equalsIgnoreCase("3")) {
                //fit data to viewHolder for ViewType 3
        } else if (viewType.equalsIgnoreCase("4")) {
//fit data to viewHolder for ViewType 4   
        } else if (viewType.equalsIgnoreCase("5")) {
//fit data to viewHolder for ViewType 5     
        }
    }

    @Override
    public int getItemCount() {
        return dataSet.size();
    }

    /**
     * returns viewType for that position by picking the viewType value from the 
     *     dataset
     */
    @Override
    public int getItemViewType(int position) {
        return dataSet.get(position).getViewType();

    }


}

You can avoid multiple conditional based viewHolder data fillings in onBindViewHolder() by assigning same ids for the similar views across viewHolders which differ in their positioning.

php.ini probably needs to read: extension=ext\php_sqlsrv_53_nts.dll

Or move the file to same directory as the php executable. This is what I did to my php5 install this week to get odbc_pdo working. :P

Additionally, that doesn't look like proper phpinfo() output. If you make a file with contents
<? phpinfo(); ?> and visit that page, the HTML output should show several sections, including one with loaded modules. (Edited to add: like shown in the screenshot of the above accepted answer)

Try this one. It may be helpful:

mysql> UPDATE mysql.user SET Password = PASSWORD('pwd') WHERE User='root';

I hope it helps.

be careful when doing this, as it is a security risk. attackers could just repeatedly inject data into session variables, which is data stored on the server. this opens you to someone overloading your server with junk session data.

here's an example of code that you wouldn't want to do..

<input type="hidden" value="..." name="putIntoSession">
..
<?php
$_SESSION["somekey"] = $_POST["putIntoSession"]
?>

Now an attacker can just change the value of putIntoSession and submit the form a billion times. Boom!

If you take the approach of creating an AJAX service to do this, you'll want to make sure you enforce security to make sure repeated requests can't be made, that you're truncating the received value, and doing some basic data validation.

SELECT * from games WHERE (lower(title) LIKE 'age of empires III');

The above query doesn't return any rows because you're looking for 'age of empires III' exact string which doesn't exists in any rows.

So in order to match with this string with different string which has 'age of empires' as substring you need to use '%your string goes here%'

More on mysql string comparision

You need to try this

SELECT * from games WHERE (lower(title) LIKE '%age of empires III%');

In Like '%age of empires III%' this will search for any matching substring in your rows, and it will show in results.

For me, the simplest way to do this is

1) Download and unzip bootstrap into vendor

2) Add the bootstrap path to your config

config.assets.paths << Rails.root.join("vendor/bootstrap-3.3.6-dist")

3) Require them

in css *= require css/bootstrap

in js //= require js/bootstrap

Done!

This methods makes the fonts load without any other special configuration and doesn't require moving the bootstrap files out of their self-contained directory.

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

Can't get exactly what you are asking but if you are using an aggregate SUM function which implies that you are grouping the table.

The query goes for MYSQL like this

Select IFNULL(SUM(COLUMN1),0) as total from mytable group by condition

Regarding tokens carrying information, JSON Web Tokens (http://jwt.io) is a brilliant technology. The main concept is to embed information elements (claims) into the token, and then signing the whole token so that the validating end can verify that the claims are indeed trustworthy.

I use this Java implementation: https://bitbucket.org/b_c/jose4j/wiki/Home

There is also a Spring module (spring-security-jwt), but I haven't looked into what it supports.

The only way I'm aware of is building CSV list and then passing it as string. Then, on SP side, just split it and do whatever you need.

(Three years late...) but I believe the answer to your second question is that SSRS essentially treats data from your datasets as unsorted; I'm not sure if it ignores any ORDER BY in the sql, or if it just assumes the data is unsorted.

To sort your groups in a particular order, you need to specify it in the report:

• Select the chart,
• In the Chart Data popup window (where you specify the Category Groups), right-click your Group and click Category Group Properties,
• Click on the Sorting option to see a control to set the Sort order

For the report I just created, the default sort order on the category was alphabetic on the category group which was basically a string code. But sometimes it can be useful to sort by some other characteristic of the data; for example, my report is of Average and Maximum processing times for messages identified by some code (the category). By setting the sort order of the group to be on [MaxElapsedMs], Z->A it draws my attention to the worst-performing message-types.

This sort of presentation won't be useful for every report but it can be an excellent tool to guide readers to have a better understanding of the data; though on other occasions you might prefer a report to have the same ordering every time it runs, in which case sorting on the category label itself may be best... and I guess there are circumstances where changing the sort order could harm understanding, such as if the categories implied some sort of ordering (such as date values?)

To enable production mode in angular 6.X.X Just go to environment file

Like this path

Your path: project>\src\environments\environment.ts

Change production: false from :

export const environment = {
  production: false
};

To

export const environment = {
  production: true
};

with Perl:

perl -e 'rename $_, "PRE_$_" for <*>'

Old question but nowadays CSS3 makes vertical alignment really simple!

Just add to #abc the following css:

display:flex;
align-items:center;

Simple Demo

Original question demo updated

Simple Example:

.vertical-align-content {_x000D_
  background-color:#f18c16;_x000D_
  height:150px;_x000D_
  display:flex;_x000D_
  align-items:center;_x000D_
  /* Uncomment next line to get horizontal align also */_x000D_
  /* justify-content:center; */_x000D_
}

<div class="vertical-align-content">_x000D_
  Hodor!_x000D_
</div>

You can simply use jQuery UI Dialog

Example:

$(function() {_x000D_
  $("#dialog").dialog();_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

The other answers so far have a lot of technical information. I will try to answer, as requested, in simple terms.

Serialization is what you do to an instance of an object if you want to dump it to a raw buffer, save it to disk, transport it in a binary stream (e.g., sending an object over a network socket), or otherwise create a serialized binary representation of an object. (For more info on serialization see Java Serialization on Wikipedia).

If you have no intention of serializing your class, you can add the annotation just above your class @SuppressWarnings("serial").

If you are going to serialize, then you have a host of things to worry about all centered around the proper use of UUID. Basically, the UUID is a way to "version" an object you would serialize so that whatever process is de-serializing knows that it's de-serializing properly. I would look at Ensure proper version control for serialized objects for more information.

This is similar to one of the answers but in different way :

scala> val x = List(1,2,3)
x: List[Int] = List(1, 2, 3)

scala> val y = x ::: 4 :: Nil
y: List[Int] = List(1, 2, 3, 4)

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug flags.

First as a baseline, try running

$ openssl s_client -connect host:443 -state -debug

You'll get a ton of output, but the lines we are interested in look like this:

SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03                        .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A

What's happening here:

• The -state flag is responsible for displaying the end of the previous section:

  SSL_connect:SSLv3 read server done A  
  

  This is only important for helping you find your place in the output.

• Then the -debug flag is showing the raw bytes being sent in the next step:

  write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
  0000 - 16 03 01 00 07 0b 00 00-03                        .........
  000c - <SPACES/NULS>
  

• Finally, the -state flag is once again reporting the result of the step that -debug just echoed:

  SSL_connect:SSLv3 write client certificate A
  

So in other words: s_client finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.

If you repeat the test, but this time include the -cert and -key flags like this:

$ openssl s_client -connect host:443 \
   -cert cert_and_key.pem \
   -key cert_and_key.pem  \
   -state -debug

your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:

SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31   ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11-                          ..^%/lC.
SSL_connect:SSLv3 write client certificate A

The 1576 bytes is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

I was having same issue.

String[] arr= new String[] { "A", "B", "C" };
Object obj = arr;

And then passed the obj as varargs argument. It worked.

You can try my suggestion for a work around in Doug's approach.
But if you want to stick with your logic though, you can try this:

Option Explicit

Sub GetUnique()

Dim rng As Range
Dim myarray, myunique
Dim i As Integer

ReDim myunique(1)

With ThisWorkbook.Sheets("Sheet1")
    Set rng = .Range(.Range("A1"), .Range("A" & .Rows.Count).End(xlUp))
    myarray = Application.Transpose(rng)
    For i = LBound(myarray) To UBound(myarray)
        If IsError(Application.Match(myarray(i), myunique, 0)) Then
            myunique(UBound(myunique)) = myarray(i)
            ReDim Preserve myunique(UBound(myunique) + 1)
        End If
    Next
End With

For i = LBound(myunique) To UBound(myunique)
    Debug.Print myunique(i)
Next

End Sub

This uses array instead of range.
It also uses Match function instead of a nested For Loop.
I didn't have the time to check the time difference though.
So I leave the testing to you.

Try using this

• Date to Time

  select cast(getdate() as time(0))
  

• Time to TinyTime

  select cast(orig_time as time(0))
  

First make data as a String with comma as the delimiter (separated with ","). Something like this

$CSV_string="No,Date,Email,Sender Name,Sender Email \n"; //making string, So "\n" is used for newLine

$rand = rand(1,50); //Make a random int number between 1 to 50.
$file ="export/export".$rand.".csv"; //For avoiding cache in the client and on the server 
                                     //side it is recommended that the file name be different.

file_put_contents($file,$CSV_string);

/* Or try this code if $CSV_string is an array
    fh =fopen($file, 'w');
    fputcsv($fh , $CSV_string , ","  , "\n" ); // "," is delimiter // "\n" is new line.
    fclose($fh);
*/

Try this CSS:

label {
  display: inline-block;
}

This may be just me being really, really picky, but I like to only define constants once. If you use any of the approaches defined above, your action constant will be defines multiple times.

To avoid this, you can do the following:

    public class Url
    {
        public string LocalUrl { get; }

        public Url(string localUrl)
        {
            LocalUrl = localUrl;
        }

        public override string ToString()
        {
            return LocalUrl;
        }
    }

    public abstract class Controller
    {
        public Url RootAction => new Url(GetUrl());

        protected abstract string Root { get; }

        public Url BuildAction(string actionName)
        {
            var localUrl = GetUrl() + "/" + actionName;
            return new Url(localUrl);
        }

        private string GetUrl()
        {
            if (Root == "")
            {
                return "";
            }

            return "/" + Root;
        }

        public override string ToString()
        {
            return GetUrl();
        }
    }

Then create your controllers, say for example the DataController:

    public static readonly DataController Data = new DataController();
    public class DataController : Controller
    {
        public const string DogAction = "dog";
        public const string CatAction = "cat";
        public const string TurtleAction = "turtle";

        protected override string Root => "data";

        public Url Dog => BuildAction(DogAction);
        public Url Cat => BuildAction(CatAction);
        public Url Turtle => BuildAction(TurtleAction);
    }

Then just use it like:

    // GET: Data/Cat
    [ActionName(ControllerRoutes.DataController.CatAction)]
    public ActionResult Etisys()
    {
        return View();
    }

And from your .cshtml (or any code)

<ul>
    <li><a href="@ControllerRoutes.Data.Dog">Dog</a></li>
    <li><a href="@ControllerRoutes.Data.Cat">Cat</a></li>
</ul>

This is definitely a lot more work, but I rest easy knowing compile time validation is on my side.

If you don't like using multi-inheritance, use extends and implements together to stay safe.

class C extends B implements A {
  // implements A here
}

I've written a log file monitor before, and I found that the impact on system performance of polling the attributes of a single file, a few times a second, is actually very small.

Java 7, as part of NIO.2 has added the WatchService API

The WatchService API is designed for applications that need to be notified about file change events.

When i posted this originally it wasnt possible so this is the workaround. Now I simply suggest using other answers.

There is no way to get the outline of the image exactly but you can fake it with a div behind the image in the center.

If my trick doesn't work then you have to cut up the image and do it for every single of the little images. (the more images the more accurate the shadow will look) but for most images it looks alright with just one img.

what you need to do is to put a wrap div around your img like so

<div id="imgWrap">
    <img id="img" scr="imgLocation">
</div>

then you put an empty divider inside the wrap (this will serve as the shadow)

<div id="imgWrap">
    <div id="shadow"> </div>
    <img id="img" scr="imgLocation">
</div>

and then you have to make the shadow appear behind the img with CSS:

#img {
    z-index: 1;
}

#shadow {
    z-index: 0; /*make this value negative if doesnt work*/
    box-shadow: 0 -130px 180px 150px rgba(255, 255, 0, 0.6);
    width: 0;
    height: 0;
}

now position the imgWrap to position the original img... to center the shadow of the img you can mess with the first two values of the box-shadow making them negative.... or you can position the img and the shadow divs absolutely making img top and left values = 0 and the shadow div values = half of img width and height respectively.

If this looks horrid cut your img up and try again.

(If you don't want the shadow behind the img just on the outline then you need to make your img opaque and make it act as if it was transparent which is not that hard and you can comment and I'll explain later)

You can simply add @HostBinding('class') class = 'someClass'; inside your @Component class.

Example:

@Component({
   selector: 'body',
   template: 'app-element'       
})
export class App implements OnInit {

  @HostBinding('class') class = 'someClass';

  constructor() {}      

  ngOnInit() {}
}

Java enums are not like C or C++ enums, which are really just labels for integers.

Java enums are implemented more like classes - and they can even have multiple attributes.

public enum Ids {
    OPEN(100), CLOSE(200);

    private final int id;
    Ids(int id) { this.id = id; }
    public int getValue() { return id; }
}

The big difference is that they are type-safe which means you don't have to worry about assigning a COLOR enum to a SIZE variable.

See http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html for more.

If you don't use prioritized tasks, this is actually pretty simple if you're using Redis. To get the task counts:

redis-cli -h HOST -p PORT -n DATABASE_NUMBER llen QUEUE_NAME

But, prioritized tasks use a different key in redis, so the full picture is slightly more complicated. The full picture is that you need to query redis for every priority of task. In python (and from the Flower project), this looks like:

PRIORITY_SEP = '\x06\x16'
DEFAULT_PRIORITY_STEPS = [0, 3, 6, 9]


def make_queue_name_for_pri(queue, pri):
    """Make a queue name for redis

    Celery uses PRIORITY_SEP to separate different priorities of tasks into
    different queues in Redis. Each queue-priority combination becomes a key in
    redis with names like:

     - batch1\x06\x163 <-- P3 queue named batch1

    There's more information about this in Github, but it doesn't look like it 
    will change any time soon:

      - https://github.com/celery/kombu/issues/422

    In that ticket the code below, from the Flower project, is referenced:

      - https://github.com/mher/flower/blob/master/flower/utils/broker.py#L135

    :param queue: The name of the queue to make a name for.
    :param pri: The priority to make a name with.
    :return: A name for the queue-priority pair.
    """
    if pri not in DEFAULT_PRIORITY_STEPS:
        raise ValueError('Priority not in priority steps')
    return '{0}{1}{2}'.format(*((queue, PRIORITY_SEP, pri) if pri else
                                (queue, '', '')))


def get_queue_length(queue_name='celery'):
    """Get the number of tasks in a celery queue.

    :param queue_name: The name of the queue you want to inspect.
    :return: the number of items in the queue.
    """
    priority_names = [make_queue_name_for_pri(queue_name, pri) for pri in
                      DEFAULT_PRIORITY_STEPS]
    r = redis.StrictRedis(
        host=settings.REDIS_HOST,
        port=settings.REDIS_PORT,
        db=settings.REDIS_DATABASES['CELERY'],
    )
    return sum([r.llen(x) for x in priority_names])

If you want to get an actual task, you can use something like:

redis-cli -h HOST -p PORT -n DATABASE_NUMBER lrange QUEUE_NAME 0 -1

From there you'll have to deserialize the returned list. In my case I was able to accomplish this with something like:

r = redis.StrictRedis(
    host=settings.REDIS_HOST,
    port=settings.REDIS_PORT,
    db=settings.REDIS_DATABASES['CELERY'],
)
l = r.lrange('celery', 0, -1)
pickle.loads(base64.decodestring(json.loads(l[0])['body']))

Just be warned that deserialization can take a moment, and you'll need to adjust the commands above to work with various priorities.

Microsoft explains it in the KB305703 article on How to start the default Internet browser programmatically by using Visual C#.

Don't forget to check the Troubleshooting section.

Parsing command line arguments in a primitive way as explained in the above answers is reasonable as long as the number of parameters that you need to deal with is not too much.

I strongly suggest you to use an industrial strength library for handling the command line arguments.

This will make your code more professional.

Such a library for C++ is available in the following website. I have used this library in many of my projects, hence I can confidently say that this one of the easiest yet useful library for command line argument parsing. Besides, since it is just a template library, it is easier to import into your project. http://tclap.sourceforge.net/

A similar library is available for C as well. http://argtable.sourceforge.net/

You have to right idea generating the url based off of the input value. The only issue is you are using window.location.href. Setting window.location.href changes the url of the current window. What you probably want to do is change the src attribute of an image.

<html>
<body>
<form>
  <input type="text" value="" id="imagename">
  <input type="button" onclick="var image = document.getElementById('the-image'); image.src='http://webpage.com/images/'+document.getElementById('imagename').value +'.png'" value="GO">
</form>
<img id="the-image">
</body>
</html>

This can also be done via CSS:pseudo-classes. Support isn't quite as wide and the answer above gives you the same result, but it's pure CSS-y =)

.ULHMenu li { border-left: solid 2px black; }
.ULHMenu li:first-child { border: 0px; }

OR:

.ULHMenu li { border-right: solid 2px black; }
.ULHMenu li:last-child { border: 0px; }

See: http://www.quirksmode.org/css/firstchild.html
Or: http://www.w3schools.com/cssref/sel_firstchild.asp

Here is a benchmark of @David Arenburg's solution there as well as a recap of some solutions posted here (@mnel, @Sven Hohenstein, @Henrik):

library(ggplot2)

df <- mtcars
DT <- as.data.table(df)
DT_32k <- rbindlist(replicate(1e3, mtcars, simplify = FALSE))
df_32k <- as.data.frame(DT_32k)
DT_32M <- rbindlist(replicate(1e6, mtcars, simplify = FALSE))
df_32M <- as.data.frame(DT_32M)
bench <- microbenchmark(
  base_32 = aggregate(hp ~ cyl, df, function(x) length(unique(x))),
  base_32k = aggregate(hp ~ cyl, df_32k, function(x) length(unique(x))),
  base_32M = aggregate(hp ~ cyl, df_32M, function(x) length(unique(x))),
  dplyr_32 = summarise(group_by(df, cyl), count = n_distinct(hp)),
  dplyr_32k = summarise(group_by(df_32k, cyl), count = n_distinct(hp)),
  dplyr_32M = summarise(group_by(df_32M, cyl), count = n_distinct(hp)),

public void setHoursWorked(){
    hoursWorked = hours;

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

I have used this command to troubleshoot client certificate negotiation:

openssl s_client -connect www.test.com:443 -prexit

The output will probably contain "Acceptable client certificate CA names" and a list of CA certificates from the server, or possibly "No client certificate CA names sent", if the server doesn't always require client certificates.

You can't import classes from the default package. You should avoid using the default package except for very small example programs.

From the Java language specification:

It is a compile time error to import a type from the unnamed package.

When generating the key, don't forget to concatenate the version and build number to the string you calculate the hash on. That way there won't be a single key that unlocks all everything you ever released.

After you find some keys or patches floating in astalavista.box.sk you'll know that you succeeded in making something popular enough that somebody bothered to crack. Rejoice!

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

I had the same problem and can't get a good tip for this over the web, so I shared this for you and for all who needs.

In my situation I copy a database (all files: frm, myd) to the data folder in MySQL data folder (using Wamp at home). All thing was OK until I want to create a table and have the error #1146 Table '...' doesn't exist!.

I use Wamp 2.1 with MySQL version 5.5.16.

My solution:

1. Export the database to file;

2. verify if exported file is really OK!!;

3. drop the database where I have issues;

4. create a new database with the same name that the last;

5. import the file to the database.

FOR ME IS PROBLEM SOLVED. Now I can create tables again without errors.

I'm on a mac and this worked for me:

open /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl

Note, do not use Chrome's built in Speed Tester (it will show you unthrottled speed). Instead use another site, like Fast.com. That will show you properly throttled speeds.

Also, the throttling settings might be hidden and can be accessed from the network bar by clicking the tiny down arrow.

Maybe this will answer your question:

<ImageView
    android:id="@+id/cover_image"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:scaleType="fitCenter"
    android:adjustViewBounds="true" />

You can ignore the scaleType attribute for this particular situation.

The addition of a string literal with an std::string yields another std::string. system expects a const char*. You can use std::string::c_str() for that:

string name = "john";
string tmp = " quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'"
system(tmp.c_str());

If you want to pass in an array of Doctrine entities, try something like this (Symfony 3.0+):

protected $entities;
protected $selectedEntities;

public function __construct($entities = null, $selectedEntities = null)
{
    $this->entities = $entities;
    $this->selectedEntities = $selectedEntities;
}

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('entities', 'entity', [
        'class' => 'MyBundle:MyEntity',
        'choices' => $this->entities,
        'property' => 'id',
        'multiple' => true,
        'expanded' => true,
        'data' => $this->selectedEntities,
    ]);
}

To add .pch file-

1) Add new .pch file to your project->New file->other->PCH file

2) Goto your project's build setting.

3) Search "prefix header". You can find that under Apple LLVM.

4) Paste this in the field $(SRCROOT)/yourPrefixHeaderFileName.pch

5) Clean and build the project. That's it!!!

From the documentation:

The font used to display text on the button. (Deprecated in iOS 3.0. Use the font property of the titleLabel instead.)

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

It is simple use below codes.

final Date todayDate = new Date();

System.out.println(todayDate);

System.out.println(new SimpleDateFormat("MM-dd-yyyy").format(todayDate));

System.out.println(new SimpleDateFormat("yyyy-MM-dd").format(todayDate));

System.out.println(todayDate);

Take a look at bash(1), you need a login shell to pickup the ~/.profile, i.e. the -l option.

Try using CSS.

body {
   margin: 0 0 auto 0;
}

The order is clockwise from the top, so top right bottom left.

if (!*ptr) { /* empty string  */}

similarly

if (*ptr)  { /* not empty */ }

To see just the Python releases, do conda search --full-name python.

You have to use a custom parsing string. I also suggest to include the invariant culture to identify that this format does not relate to any culture. Plus, it will prevent a warning in some code analysis tools.

var date = DateTime.ParseExact(value, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["files"]["name"][$key];
    $file_tmp=$_FILES["files"]["tmp_name"][$key];
    $ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

and you must check your HTML code

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>

PARTITION BY segregate sets, this enables you to be able to work(ROW_NUMBER(),COUNT(),SUM(),etc) on related set independently.

In your query, the related set comprised of rows with similar cdt.country_code, cdt.account, cdt.currency. When you partition on those columns and you apply ROW_NUMBER on them. Those other columns on those combination/set will receive sequential number from ROW_NUMBER

But that query is funny, if your partition by some unique data and you put a row_number on it, it will just produce same number. It's like you do an ORDER BY on a partition that is guaranteed to be unique. Example, think of GUID as unique combination of cdt.country_code, cdt.account, cdt.currency

newid() produces GUID, so what shall you expect by this expression?

select
   hi,ho,
   row_number() over(partition by newid() order by hi,ho)
from tbl;

...Right, all the partitioned(none was partitioned, every row is partitioned in their own row) rows' row_numbers are all set to 1

Basically, you should partition on non-unique columns. ORDER BY on OVER needed the PARTITION BY to have a non-unique combination, otherwise all row_numbers will become 1

An example, this is your data:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','X'),
('A','Y'),
('A','Z'),
('B','W'),
('B','W'),
('C','L'),
('C','L');

Then this is analogous to your query:

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho)
from tbl;

What will be the output of that?

HI  HO  COLUMN_2
A   X   1
A   Y   1
A   Z   1
B   W   1
B   W   2
C   L   1
C   L   2

You see thee combination of HI HO? The first three rows has unique combination, hence they are set to 1, the B rows has same W, hence different ROW_NUMBERS, likewise with HI C rows.

Now, why is the ORDER BY needed there? If the previous developer merely want to put a row_number on similar data (e.g. HI B, all data are B-W, B-W), he can just do this:

select
   hi,ho,
   row_number() over(partition by hi,ho)
from tbl;

But alas, Oracle(and Sql Server too) doesn't allow partition with no ORDER BY; whereas in Postgresql, ORDER BY on PARTITION is optional: http://www.sqlfiddle.com/#!1/27821/1

select
   hi,ho,
   row_number() over(partition by hi,ho)
from tbl;

Your ORDER BY on your partition look a bit redundant, not because of the previous developer's fault, some database just don't allow PARTITION with no ORDER BY, he might not able find a good candidate column to sort on. If both PARTITION BY columns and ORDER BY columns are the same just remove the ORDER BY, but since some database don't allow it, you can just do this:

SELECT cdt.*,
        ROW_NUMBER ()
        OVER (PARTITION BY cdt.country_code, cdt.account, cdt.currency
              ORDER BY newid())
           seq_no
   FROM CUSTOMER_DETAILS cdt

You cannot find a good column to use for sorting similar data? You might as well sort on random, the partitioned data have the same values anyway. You can use GUID for example(you use newid() for SQL Server). So that has the same output made by previous developer, it's unfortunate that some database doesn't allow PARTITION with no ORDER BY

Though really, it eludes me and I cannot find a good reason to put a number on the same combinations (B-W, B-W in example above). It's giving the impression of database having redundant data. Somehow reminded me of this: How to get one unique record from the same list of records from table? No Unique constraint in the table

It really looks arcane seeing a PARTITION BY with same combination of columns with ORDER BY, can not easily infer the code's intent.

Live test: http://www.sqlfiddle.com/#!3/27821/6

But as dbaseman have noticed also, it's useless to partition and order on same columns.

You have a set of data like this:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','X'),
('A','X'),
('A','X'),
('B','Y'),
('B','Y'),
('C','Z'),
('C','Z');

Then you PARTITION BY hi,ho; and then you ORDER BY hi,ho. There's no sense numbering similar data :-) http://www.sqlfiddle.com/#!3/29ab8/3

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;

Output:

HI  HO  ROW_QUERY_A
A   X   1
A   X   2
A   X   3
B   Y   1
B   Y   2
C   Z   1
C   Z   2

See? Why need to put row numbers on same combination? What you will analyze on triple A,X, on double B,Y, on double C,Z? :-)

You just need to use PARTITION on non-unique column, then you sort on non-unique column(s)'s unique-ing column. Example will make it more clear:

create table tbl(hi varchar, ho varchar);

insert into tbl values
('A','D'),
('A','E'),
('A','F'),
('B','F'),
('B','E'),
('C','E'),
('C','D');

select
   hi,ho,
   row_number() over(partition by hi order by ho) as nr
from tbl;

PARTITION BY hi operates on non unique column, then on each partitioned column, you order on its unique column(ho), ORDER BY ho

Output:

HI  HO  NR
A   D   1
A   E   2
A   F   3
B   E   1
B   F   2
C   D   1
C   E   2

That data set makes more sense

Live test: http://www.sqlfiddle.com/#!3/d0b44/1

And this is similar to your query with same columns on both PARTITION BY and ORDER BY:

select
   hi,ho,
   row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;

And this is the ouput:

HI  HO  NR
A   D   1
A   E   1
A   F   1
B   E   1
B   F   1
C   D   1
C   E   1

See? no sense?

Live test: http://www.sqlfiddle.com/#!3/d0b44/3

Finally this might be the right query:

SELECT cdt.*,
     ROW_NUMBER ()
     OVER (PARTITION BY cdt.country_code, cdt.account -- removed: cdt.currency
           ORDER BY 
               -- removed: cdt.country_code, cdt.account, 
               cdt.currency) -- keep
        seq_no
FROM CUSTOMER_DETAILS cdt

I have some virtual directories and I cannot use Directory methods. So, I made a simple split/join function for those interested. Not as safe though.

var splitResult = filePath.Split(new[] {'/', '\\'}, StringSplitOptions.RemoveEmptyEntries);
var newFilePath = Path.Combine(filePath.Take(splitResult.Length - 1).ToArray());

So, if you want to move 4 up, you just need to change the 1 to 4 and add some checks to avoid exceptions.

You'll need to use an Iterator to loop through the keys to get their values.

Here's a Kotlin implementation, you will realised that the way I got the string is using optString(), which is expecting a String or a nullable value.

val keys = jsonObject.keys()
while (keys.hasNext()) {
    val key = keys.next()
    val value = targetJson.optString(key)        
}

Wikipedia has the following information about USING:

The USING construct is more than mere syntactic sugar, however, since the result set differs from the result set of the version with the explicit predicate. Specifically, any columns mentioned in the USING list will appear only once, with an unqualified name, rather than once for each table in the join. In the case above, there will be a single DepartmentID column and no employee.DepartmentID or department.DepartmentID.

Tables that it was talking about:

The Postgres documentation also defines them pretty well:

The ON clause is the most general kind of join condition: it takes a Boolean value expression of the same kind as is used in a WHERE clause. A pair of rows from T1 and T2 match if the ON expression evaluates to true.

The USING clause is a shorthand that allows you to take advantage of the specific situation where both sides of the join use the same name for the joining column(s). It takes a comma-separated list of the shared column names and forms a join condition that includes an equality comparison for each one. For example, joining T1 and T2 with USING (a, b) produces the join condition ON T1.a = T2.a AND T1.b = T2.b.

Furthermore, the output of JOIN USING suppresses redundant columns: there is no need to print both of the matched columns, since they must have equal values. While JOIN ON produces all columns from T1 followed by all columns from T2, JOIN USING produces one output column for each of the listed column pairs (in the listed order), followed by any remaining columns from T1, followed by any remaining columns from T2.

It is same as above answers, but is simple in steps

c:\SRC\folder1

c:\SRC\folder2

c:\SRC\folder3

c:\SRC\folder4

to copy all above folders to c:\DST\ except folder1 and folder2.

Step1: create a file c:\list.txt with below content, one folder name per one line

folder1\

folder2\

Step2: Go to command pompt and run as below xcopy c:\SRC*.* c:\DST*.* /EXCLUDE:c:\list.txt

It's possible to have normal getter/setter pair. You just need to specify access mode in @JsonProperty

Here is unit test for that:

public class JsonPropertyTest {

  private static class TestJackson {

    private String color;

    @JsonProperty(value = "device_color", access = JsonProperty.Access.READ_ONLY)
    public String getColor() {
      return color;
    };

    @JsonProperty(value = "color", access = JsonProperty.Access.WRITE_ONLY)
    public void setColor(String color) {
      this.color = color;
    }

  }

  @Test
  public void shouldParseWithAccessModeSpecified() throws Exception {
    String colorJson = "{\"color\":\"red\"}";
    ObjectMapper mapper = new ObjectMapper();
    TestJackson colotObject = mapper.readValue(colorJson, TestJackson.class);

    String ser = mapper.writeValueAsString(colotObject);
    System.out.println("Serialized colotObject: " + ser);
  }
}

I got the output as follows:

Serialized colotObject: {"device_color":"red"}

I just ran into this problem myself.

First, modify your code slightly:

var download = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                  +"<"+this.gamesave.tagName+">"
                  +this.xml.firstChild.innerHTML
                  +"</"+this.gamesave.tagName+">";

this.loader.src = "data:application/x-forcedownload;base64,"+
                  btoa(download);

Then use your favorite web inspector, put a breakpoint on the line of code that assigns this.loader.src, then execute this code:

for (var i = 0; i < download.length; i++) {
  if (download[i].charCodeAt(0) > 255) {
    console.warn('found character ' + download[i].charCodeAt(0) + ' "' + download[i] + '" at position ' + i);
  }
}

Depending on your application, replacing the characters that are out of range may or may not work, since you'll be modifying the data. See the note on MDN about unicode characters with the btoa method:

Do, I need to resolve all the conflicts before proceeding to next cherry -pick

Yes, at least with the standard git setup. You cannot cherry-pick while there are conflicts.

Furthermore, in general conflicts get harder to resolve the more you have, so it's generally better to resolve them one by one.

That said, you can cherry-pick multiple commits at once, which would do what you are asking for. See e.g. How to cherry-pick multiple commits . This is useful if for example some commits undo earlier commits. Then you'd want to cherry-pick all in one go, so you don't have to resolve conflicts for changes that are undone by later commits.

Further, is it suggested to do cherry-pick or branch merge in this case?

Generally, if you want to keep a feature branch up to date with main development, you just merge master -> feature branch. The main advantage is that a later merge feature branch -> master will be much less painful.

Cherry-picking is only useful if you must exclude some changes in master from your feature branch. Still, this will be painful so I'd try to avoid it.

As you say, this is strictly undefined behaviour, though it will "work" on many platforms. The real reason for using unions is to create variant records.

union A {
   int i;
   double d;
};

A a[10];    // records in "a" can be either ints or doubles 
a[0].i = 42;
a[1].d = 1.23;

Of course, you also need some sort of discriminator to say what the variant actually contains. And note that in C++ unions are not much use because they can only contain POD types - effectively those without constructors and destructors.

You cannot calculate the differences separately ... what difference would that yield for 7:59 and 8:00 o'clock? Try

import time
time.time()

which gives you the seconds since the start of the epoch.

You can then get the intermediate time with something like

timestamp1 = time.time()
# Your code here
timestamp2 = time.time()
print "This took %.2f seconds" % (timestamp2 - timestamp1)

And if your dates are standardized by importing datetime package, you can simply use:

df[(df['date']>datetime.date(2016,1,1)) & (df['date']<datetime.date(2016,3,1))]  

For standarding your date string using datetime package, you can use this function:

import datetime
datetime.datetime.strptime

If you have the need to use other libraries in projects --typescript-- not just in projects - angle - you can look for tds's (TypeScript Declaration File) that are depares and that have information of methods, types, functions, etc. , which can be used by TypeScript, usually without the need for import. declare var is the last resource

npm install @types/lib-name --save-dev

You cannot move the mousepointer with javascript.

Just think about the implications for a second, if you could ;)

1. User thinks: "hey I'd like to click this link"
2. Javascript moves mousecursor to another link
3. User clicks wrong link and inadvertently downloads malware that formats his c-drive and eats his candy

Well I needed something that would reduce seconds into hours minutes and seconds, but would exceed 24 hours, and not reduce further down into days.

Here is a simple function that works. You can probably improve it... But here it is:

function formatSeconds($seconds)
{
    $hours = 0;$minutes = 0;
    while($seconds >= 60){$seconds -= 60;$minutes++;}
    while($minutes >= 60){$minutes -=60;$hours++;}
    $hours = str_pad($hours, 2, '0', STR_PAD_LEFT);
    $minutes = str_pad($minutes, 2, '0', STR_PAD_LEFT);
    $seconds = str_pad($seconds, 2, '0', STR_PAD_LEFT);
    return $hours.":".$minutes.":".$seconds;
}

This method will create a copy of your list but your type should be serializable.

Use:

List<Student> lstStudent = db.Students.Where(s => s.DOB < DateTime.Now).ToList().CopyList(); 

Method:

public static List<T> CopyList<T>(this List<T> lst)
    {
        List<T> lstCopy = new List<T>();
        foreach (var item in lst)
        {
            using (MemoryStream stream = new MemoryStream())
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, item);
                stream.Position = 0;
                lstCopy.Add((T)formatter.Deserialize(stream));
            }
        }
        return lstCopy;
    }

Easy way I have found is to open the command prompt and browse through the folder you mention until you find the DLL you want - you can then user the copy command to get it out. Windows Explorer has a "helpful" special view of this folder.

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

You can also run exactly same command at Cmd.exe command-line using PowerShell. I'd go with this approach for simplicity...

C:\>PowerShell -Command "temperature | prismcom.exe usb"

Please read up on Understanding the Windows PowerShell Pipeline

You can also type in C:\>PowerShell at the command-line and it'll put you in PS C:\> mode instanctly, where you can directly start writing PS.

Check these step:

1. Check MVC is installed properly.
2. Check the project's property and see what is the project Target Framework. If the target framework is not set to .Net Framework 4, set it.

Note: if target framework is set to .Net Framework 4 Client Profile, it will not list MVC reference on references list. You can find different between .Net Framework 4 and .Net Framework 4 Client Profile here.

The .NET Framework 4 Client Profile is a subset of the .NET Framework 4 that is optimized for client applications. It provides functionality for most client applications, including Windows Presentation Foundation (WPF), Windows Forms, Windows Communication Foundation (WCF), and ClickOnce features. This enables faster deployment and a smaller install package for applications that target the .NET Framework 4 Client Profile.

No, anonymous types cannot implement an interface. From the C# programming guide:

Anonymous types are class types that consist of one or more public read-only properties. No other kinds of class members such as methods or events are allowed. An anonymous type cannot be cast to any interface or type except for object.

getClass().getResource() uses the class loader to load the resource. This means that the resource must be in the classpath to be loaded.

When doing it with Eclipse, everything you put in the source folder is "compiled" by Eclipse:

• .java files are compiled into .class files that go the the bin directory (by default)
• other files are copied to the bin directory (respecting the package/folder hirearchy)

When launching the program with Eclipse, the bin directory is thus in the classpath, and since it contains the Test.properties file, this file can be loaded by the class loader, using getResource() or getResourceAsStream().

If it doesn't work from the command line, it's thus because the file is not in the classpath.

Note that you should NOT do

FileInputStream inputStream = new FileInputStream(new File(getClass().getResource(url).toURI()));

to load a resource. Because that can work only if the file is loaded from the file system. If you package your app into a jar file, or if you load the classes over a network, it won't work. To get an InputStream, just use

getClass().getResourceAsStream("Test.properties")

And finally, as the documentation indicates,

Foo.class.getResourceAsStream("Test.properties")

will load a Test.properties file located in the same package as the class Foo.

Foo.class.getResourceAsStream("/com/foo/bar/Test.properties")

will load a Test.properties file located in the package com.foo.bar.

I was searching for a similar solution and found this one use full.

var es;

function startTask() {
    es = new EventSource('yourphpfile.php');

//a message is received
es.addEventListener('message', function(e) {
    var result = JSON.parse( e.data );

    console.log(result.message);       

    if(e.lastEventId == 'CLOSE') {
        console.log('closed');
        es.close();
        var pBar = document.getElementById('progressor');
        pBar.value = pBar.max; //max out the progress bar
    }
    else {

        console.log(response); //your progress bar action
    }
});

es.addEventListener('error', function(e) {
    console.log('error');
    es.close();
});

}

and your server outputs

header('Content-Type: text/event-stream');
// recommended to prevent caching of event data.
header('Cache-Control: no-cache'); 

function send_message($id, $message, $progress) {
    $d = array('message' => $message , 'progress' => $progress); //prepare json

    echo "id: $id" . PHP_EOL;
    echo "data: " . json_encode($d) . PHP_EOL;
    echo PHP_EOL;

   ob_flush();
   flush();
}


//LONG RUNNING TASK
 for($i = 1; $i <= 10; $i++) {
    send_message($i, 'on iteration ' . $i . ' of 10' , $i*10); 

    sleep(1);
 }

send_message('CLOSE', 'Process complete');

We would create our own function in js like echo "Hello world".

function echo( ...s ) // rest operator
 { 
   for(var i = 0; i < s.length; i++ ) {

    document.write(s[i] + ' '); // quotes for space

   }

 } 

  // Now call to this function like echo

 echo('Hellow', "World");

Note: (...) rest operator dotes for access more parameters in one as object/array, to get value from object/array we should iterate the whole object/array by using for loop, like above and s is name i just kept you can write whatever you want.

There's also the iScroll project which allows you to style the scrollbars plus get it to work with touch devices. http://cubiq.org/iscroll-4

Here is an example code that you may use:

$ STR="String;1;2;3"
$ for EACH in `echo "$STR" | grep -o -e "[^;]*"`; do
    echo "Found: \"$EACH\"";
done

grep -o -e "[^;]*" will select anything that is not ';', therefore spliting the string by ';'.

Hope that help.

For a local File in case of ReactJS. Try

import Image from "../../assets/image.jpg";

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
>Hello
</div>

This is the case of ReactJS with inline styling where Image is a local file that you must have imported with a path.

To convert binary string to hexadecimal string, we don't need any external libraries. Use formatted string literals (known as f-strings). This feature was added in python 3.6 (PEP 498)

>>> bs = '0000010010001101'
>>> hexs = f'{int(bs, 2):X}'
>>> print(hexs)
>>> '48D'

If you want hexadecimal strings in small-case, use small "x" as follows

f'{int(bs, 2):x}'

Where bs inside f-string is a variable which contains binary strings assigned prior

f-strings are lost more useful and effective. They are not being used at their full potential.

There is a site called Softies on Rails that is written by a couple of ex-.NET developers that may be of some use. They have a book called Rails for .NET Developers coming out in the next few months...

I started out on a Windows box using the RadRails plugin for Eclipse and the RubyWeaver extension for Dreamweaver (back during the 1.x days of Rails). Since then I have moved to a Mac running TextMate and haven't thought of going back.

As for books, I started with The Ruby Way and Agile Web Development with Rails. It definately helps to build a background in Ruby as you start to make your way into Rails development.

Definately watch the Railscast series by Ryan Bates.

I have a webserver running on my localhost.

If I open up the emulator and want to connect to my localhost I am using 192.168.x.x. This means you should use your local lan ip address. By the way, your HttpResponseException (Bad Request) doesn't mean that the host is not reachable.

Some other errors lead to this exception.

A small update to what @control freak and @skatun wrote previously (sorry I don't have enough reputation to just make a comment). I used skatun's code and it worked well for me except that it was creating a larger array than what I needed. Therefore, I changed:

ReDim aPreservedArray(nNewFirstUBound, nNewLastUBound)

to:

ReDim aPreservedArray(LBound(aArrayToPreserve, 1) To nNewFirstUBound, LBound(aArrayToPreserve, 2) To nNewLastUBound)

This will maintain whatever the original array's lower bounds were (either 0, 1, or whatever; the original code assumes 0) for both dimensions.

Admittedly, I stole this question from somewhere else (can't remember where I read it any more) but thought it was funny:

Q: What is T_PAAMAYIM_NEKUDOTAYIM?
A: Its the scope resolution operator (double colon)

An experienced PHP'er immediately knows what it means. Less experienced (and not Hebrew) developers may want to read this.

But more serious questions now:

Q: What is the cause of this warning: 'Warning: Cannot modify header information - headers already sent', and what is a good practice to prevent it?
A: Cause: body data was sent, causing headers to be sent too.
Prevention: Be sure to execute header specific code first before you output any body data. Be sure you haven't accidentally sent out whitespace or any other characters.

Q: What is wrong with this query: "SELECT * FROM table WHERE id = $_POST[ 'id' ]"?
A: 1. It is vulnarable to SQL injection. Never use user input directly in queries. Sanitize it first. Preferebly use prepared statements (PDO) 2. Don't select all columns (*), but specify every single column. This is predominantly ment to prevent queries hogging up memory when for instance a BLOB column is added at some point in the future.

Q: What is wrong with this if statement: if( !strpos( $haystack, $needle ) ...?
A: strpos returns the index position of where it first found the $needle, which could be 0. Since 0 also resolves to false the solution is to use strict comparison: if( false !== strpos( $haystack, $needle )...

Q: What is the preferred way to write this if statement, and why?
if( 5 == $someVar ) or if( $someVar == 5 )
A: The former, as it prevents accidental assignment of 5 to $someVar when you forget to use 2 equalsigns ($someVar = 5), and will cause an error, the latter won't.

Q: Given this code:

function doSomething( &$arg )
{
    $return = $arg;
    $arg += 1;
    return $return;
}

$a = 3;
$b = doSomething( $a );

...what is the value of $a and $b after the function call and why?
A: $a is 4 and $b is 3. The former because $arg is passed by reference, the latter because the return value of the function is a copy of (not a reference to) the initial value of the argument.

OOP specific

Q: What is the difference between public, protected and private in a class definition?
A: public makes a class member available to "everyone", protected makes the class member available to only itself and derived classes, private makes the class member only available to the class itself.

Q: What is wrong with this code:

class SomeClass
{
    protected $_someMember;

    public function __construct()
    {
        $this->_someMember = 1;
    }

    public static function getSomethingStatic()
    {
        return $this->_someMember * 5; // here's the catch
    }
}

A: Static methods don't have access to $this, because static methods can be executed without instantiating a class.

Q: What is the difference between an interface and an abstract class?
A: An interface defines a contract between an implementing class is and an object that calls the interface. An abstract class pre-defines certain behaviour for classes that will extend it. To a certain degree this can also be considered a contract, since it garantuees certain methods to exist.

Q: What is wrong with classes that predominantly define getters and setters, that map straight to it's internal members, without actually having methods that execute behaviour?
A: This might be a code smell since the object acts as an ennobled array, without much other use.

Q: Why is PHP's implementation of the use of interfaces sub-optimal?
A: PHP doesn't allow you to define the expected return type of the method's, which essentially renders interfaces pretty useless. :-P

If you are using python 3 and windows 10, the best solution that I found to be working is from Giovanni Gianni. This played for me in the male voice:

import win32com.client as wincl
speak = wincl.Dispatch("SAPI.SpVoice")
speak.Speak("This is the pc voice speaking")

I also found this video on youtube so if you really want to, you can get someone you know and make your own DIY tts voice.

I also got the same error in Chrome (I didn't test other browers). It was due to the fact that I was navigating on domain.com instead of www.domain.com. A bit strange, but I could solve the problem by adding the following lines to .htaccess. It redirects domain.com to www.domain.com and the problem was solved. I am a lazy web visitor so I almost never type the www but apparently in some cases it is required.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

I had the same issue. It was related to the Build Settings -> Code Signing Identity -> Release which was set to iOS Developer. If has to be set to iOS Distribution in order for Xcode upload to work.

In Swift 4:

self.view.layoutIfNeeded()

1. Check "Run" configuration to see which port it is using (8081).
2. Find all the other processes using that port lsof -t -i :8081
3. Kill the processes on that port. kill PROCESS_ID
4. Run Tomcat in Debug mode.

In my case, I wasted so much time on changing debugger port but it was not the issue. Since tomcat was not able to run on the port I chose in Run configuration, I was not able to debug my service.

If you use Linux or WSL you can use the forensic application binwalk to extract .img files (which are usually disk images) like this:

1. Use your distribution package manager or follow the manual instructions to install binwalk.

2. Use the command binwalk -e FILENAME.img to extract recognized content into a automatically generated directory.

You could try attaching handlers to various events of BitmapImage:

• DecodeFailed
• DownloadFailed
• DownloadCompleted

They might tell you a little about what's going on, as far as the image is concerned.

If you don't want to use OutlineButton and want to stick to normal RaisedButton, you can wrap your button in ClipRRect or ClipOval like:

ClipRRect(
  borderRadius: BorderRadius.circular(40),
  child: RaisedButton(
    child: Text("Button"),
    onPressed: () {},
  ),
),

Alternativly if your using bootstrap then you can just add align-middle to vertical align the element.

<button id="whaever" class="btn btn-large btn-primary" style="padding: 20px;" name="Continue" type="submit">Continue
    <i class="icon-ok align-middle" style="font-size:40px;"></i>
</button>

The answer from Kukkuz did not work for me until I added in this dependency into the pom file:

<!-- Spring boot Thymeleaf -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

From the guide here.

As well as updating the registry resources as outlined here.

It then started working just fine. If anyone in the future runs into the same issue and following the first answer does not solve your problem, follow these 2 other steps after utilizing the code in @Kukkuz's answer and see if that makes a difference.

Do NEVER put a ListView inside of a ScrollView! You can find more information about that topic on Google. In your case, use a LinearLayout instead of the ListView and add the elements programmatically.

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

I have come to share an solution. The error happened to me after forcing the notbook to hang up. possible solution clean preject.

Tarkus's answer works well. However, I would suggest replacing VIEWSTATE with SESSION.

The current page's VIEWSTATE only works while the current page posts back to itself and is gone once the user is redirected away to another page. SESSION persists the sort order on more than just the current page's post-back. It persists it across the entire duration of the session. This means that the user can surf around to other pages, and when he comes back to the given page, the sort order he last used still remains. This is usually more convenient.

There are other methods, too, such as persisting user profiles.

I recommend this article for a very good explanation of ViewState and how it works with a web page's life cycle: https://msdn.microsoft.com/en-us/library/ms972976.aspx

To understand the difference between VIEWSTATE, SESSION and other ways of persisting variables, I recommend this article: https://msdn.microsoft.com/en-us/library/75x4ha6s.aspx

Use numpy.

import numpy as np
b = list(np.array(a)**2)

nth-last-child sounds like it was specifically designed to solve this problem, so I doubt whether there is a more compatible alternative. Support looks pretty decent, though.

numpy.ndarray can contain any type of element, e.g. int, float, string etc. Check the type an do a conversion if neccessary.

Here is my one liner. Here 'c' is the name of the column

df.select('c').withColumn('isNull_c',F.col('c').isNull()).where('isNull_c = True').count()

you can use this http://www.md5decrypt.org/ or this http://md5.gromweb.com/ it will decrypt your md5 code

If you want to do it line by line:

Dim sFileText As String
Dim iInputFile As Integer, iOutputFile as integer

iInputFile = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iInputFile 
iOutputFile = FreeFile
Open "C:\Clients\Converter\2.txt" For Output As #iOutputFile 
Do While Not EOF(iInputFile)
   Line Input #iInputFile , sFileText
   ' sFileTextis a single line of the original file
   ' you can append anything to it before writing to the other file
   Print #iOutputFile, sFileText 
Loop
Close #iInputFile 
Close #iOutputFile 

The accepted answer doesn't work for UILocalNotification. For some reason, %%%% (4 percent signs) or the unicode character '\uFF05' only work for this.

So to recap, when formatting your string you may use %%. However, if your string is part of a UILocalNotification, use %%%% or \uFF05.

On each loop of the result set, you're appending a new root element to the document, creating an XML document like this:

<?xml version="1.0"?>
<mycatch>...</mycatch>
<mycatch>...</mycatch>
...

An XML document can only have one root element, which is why the error is stating there is "extra content". Create a single root element and add all the mycatch elements to that:

$root = $dom->createElement("root");
$dom->appendChild($root);
// ...
while ($row = @mysql_fetch_assoc($result)){
  $node = $dom->createElement("mycatch");
  $root->appendChild($node);

Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.

# in your PHP code:
ini_set('display_errors', '0');     # don't show any errors...
error_reporting(E_ALL | E_STRICT);  # ...but do log them

They will be logged to your standard system log, or use the error_log directive to specify exactly where you want errors to go.

Another possible answer for Windows 10:

The command httpd -k restart does not work on my machine somehow.

Try to use the Windows 10 Service to restart the relative service.

Yet another solution would be to create a Dictionary<string, object> before calling TextBoxFor and pass that dictionary. In the dictionary, add "disabled" key only if the textbox is to be diabled. Not the neatest solution but simple and straightforward.

for everything related to Python's style guide: i'd recommend you read PEP8.

To answer your question:

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

Or if you use the six library

from six.moves import reduce

None of the proposed answers did work for me. (e.g. in notepad++) But

^.*?(?=\;)

did.

Make clickable icon to focus inside the text input element.

CSS

.myClass {
    font-size:20px;
    position:absolute; top:10px; left:10px;
}

HTML

<div>
    <label style="position:relative;">
         <i class="myClass fa fa-address-book-o"></i>
         <input class="w3-input" type="text" style="padding-left:40px;">
    </label>
</div>

Just add whichever icon you like inside the <i> tag, from Font Awesome library and enjoy the results.

Or you can use what JQuery alreay made for you:

http://jqueryui.com/datepicker/#icon-trigger

It's what you are trying to achieve isn't it?

I found this page while searching for a solution to a similar error message using git pull on a remote host:

$ git pull
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I was connected from my local machine to the remote host via ssh -AY remote_hostname. This is not a solution to OP's question, but useful for others who come across this page, so posting it here.

Note that in my case, git pull works fine on my local machine (that is, ssh key had been set up, and added to the GitHub account, etc). I solved my issue by adding this to ~/.ssh/config on my laptop:

Host *
     ForwardAgent yes

I then re-connected to the remote host with ssh -AY remote_hostname, and git pull now worked. The change in the config enables to forward my ssh keypair from my local machine to any host. The -A option to ssh actually forwards it in that ssh session. See more details here.

If you want check access to databases for a particular login has use this simple script as below:

sys.sp_helplogins @LoginNamePattern = 'Domain\login' -- sysname

I had the same issue a few days ago and I found this thread Twitter Developer Forum that points to some incompatibility with versions of gradle/build-tools/crashalics.

My problem was slightly different from yours as I'm not using alpha-3 I'm using 1.5. But on my update I also changed to the latest gradle distribution gradle-2.9-all.zip.

So probably/maybe you can fix it by changing to the latest gradle version. But If it does not work, you'll really have to be patient and wait until build tools V2.0 is not in alpha anymore OR the Crashalitycs team, fix the incompatibility.

<div style="display: inline">Is this what you meant?</div>

import re
pattern = re.compile("^([A-Z][0-9]+)+$")
pattern.search(string)

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

I find the easy way to do it for non-repeatable updates is to use MS Access and create a linked table, then update the data as you need. I guess the MS Access team doesn't talk to the SMSS team :)

For ASP.NET Core You can use asp-route-* attribute:

<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">

Other in details example: Imagine that you have a Vehicle Controller with actions

Index

Details

Edit

and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.

//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
     ..............
     ..............
     public string ReturnUrl {get;set;}
}



Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>

Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>

Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
        <div class="box-footer">
            <a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
            <button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
        </div>
    </form>

In your controller:

// GET: Vehicle/Edit/5
    public ActionResult Edit(int id,string previous)
    {
            var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
            var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
    //or by this code if you are not use automapper
    var viewModel = new VehicleViewModel();

    if (!string.IsNullOrWhiteSpace(previous)
                viewModel.ReturnUrl = previous;
            else
                viewModel.ReturnUrl = "Index";
            return View(viewModel);
        }



[HttpPost]
    public IActionResult Edit(VehicleViewModel model, string previous)
    {
            if (!string.IsNullOrWhiteSpace(previous))
                model.ReturnUrl = previous;
            else
                model.ReturnUrl = "Index";
            ............. 
            .............
            return RedirectToAction(model.ReturnUrl);
    }

This is my implementation.

public class Test {
    public String toBinary(String text) {
        StringBuilder sb = new StringBuilder();

        for (char character : text.toCharArray()) {
            sb.append(Integer.toBinaryString(character) + "\n");
        }

        return sb.toString();

    }
}

long a = 1111;
Long b = new Long(1113);

System.out.println(b.equals(a) ? "equal" : "different");
System.out.println((long) b == a ? "equal" : "different");

I have tried this then i fixed my issue. It will calculate all media-breakpoint automatically by given rate (base-size/rate-size)

$base-size: 16;
$rate-size-xl: 24;

    // set default size for all cases;
    :root {
      --size: #{$base-size};
    }

    // if it's smaller then LG it will set size rate to 16/16;
    // example: if size set to 14px, it will be 14px * 16 / 16 = 14px
    @include media-breakpoint-down(lg) {
      :root {
        --size: #{$base-size};
      }
    }

    // if it is bigger then XL it will set size rate to 24/16;
    // example: if size set to 14px, it will be 14px * 24 / 16 = 21px
    @include media-breakpoint-up(xl) {
      :root {
        --size: #{$rate-size-xl};
      }
    }

@function size($px) {
   @return calc(#{$px} / $base-size * var(--size));
}

div {
  font-size: size(14px);
  width: size(150px);
}

I solved the problem with this code:

using System.IO;

var path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location.Substring(0, Assembly.GetEntryAssembly().Location.IndexOf("bin\\")))

Will result always be the floor of the division? What is the defined behavior?

Not quite. It rounds toward 0, rather than flooring.

6.5.5 Multiplicative operators

6 When integers are divided, the result of the / operator is the algebraic quotient with any fractional part discarded.⁸⁸⁾ If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a.

and the corresponding footnote:

88. This is often called ‘‘truncation toward zero’’.

Of course two points to note are:

3 The usual arithmetic conversions are performed on the operands.

and:

5 The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. In both operations, if the value of the second operand is zero, the behavior is undefined.

[Note: Emphasis mine]

You're only adding the File object to the JSON object. The File object only contains meta information about the file: Path, name and so on.

You must load the image and read the bytes from it. Then put these bytes into the JSON object.

Can use generics to combine arrays. Following code can easily be expanded to three arrays. This way you never need to duplicate code for different type of arrays. Some of the above answers seem overly complex to me.

private static T[] CombineTwoArrays<T>(T[] a1, T[] a2)
    {
        T[] arrayCombined = new T[a1.Length + a2.Length];
        Array.Copy(a1, 0, arrayCombined, 0, a1.Length);
        Array.Copy(a2, 0, arrayCombined, a1.Length, a2.Length);
        return arrayCombined;
    }

Just like the accepted answer says a HashSet doesn't have an order. If order is important you can continue to use a List and check if it contains the item before you add it.

if (_remoteDevices.Contains(rDevice))
    _remoteDevices.Add(rDevice);

Performing List.Contains() on a custom class/object requires implementing IEquatable<T> on the custom class or overriding the Equals. It's a good idea to also implement GetHashCode in the class as well. This is per the documentation at https://msdn.microsoft.com/en-us/library/ms224763.aspx

public class RemoteDevice: IEquatable<RemoteDevice>
{
    private readonly int id;
    public RemoteDevice(int uuid)
    {
        id = id
    }
    public int GetId
    {
        get { return id; }
    }

    // ...

    public bool Equals(RemoteDevice other)
    {
        if (this.GetId == other.GetId)
            return true;
        else
            return false;
    }
    public override int GetHashCode()
    {
        return id;
    }
}

You could just declare a DBMS_SQL.VARCHAR2_TABLE to hold an in-memory variable length array indexed by a BINARY_INTEGER:

DECLARE
   name_array dbms_sql.varchar2_table;
BEGIN
   name_array(1) := 'Tim';
   name_array(2) := 'Daisy';
   name_array(3) := 'Mike';
   name_array(4) := 'Marsha';
   --
   FOR i IN name_array.FIRST .. name_array.LAST
   LOOP
      -- Do something
   END LOOP;
END;

You could use an associative array (used to be called PL/SQL tables) as they are an in-memory array.

DECLARE
   TYPE employee_arraytype IS TABLE OF employee%ROWTYPE
        INDEX BY PLS_INTEGER;
   employee_array employee_arraytype;
BEGIN
   SELECT *
     BULK COLLECT INTO employee_array
     FROM employee
    WHERE department = 10;
   --
   FOR i IN employee_array.FIRST .. employee_array.LAST
   LOOP
      -- Do something
   END LOOP;
END;

The associative array can hold any make up of record types.

Hope it helps, Ollie.

If you are using eclipse there is a "Skip Tests" checkbox on the configuration page.

Run configurations ? Maven Build ? New ? Main tab ? Skip Tests

You can try

#include <iostream>
#include <conio.h>

int main() {

    //some codes

    getch();
    return 0;
}

There is also EXISTS:

SELECT count(*) AS post_ct
FROM   posts p
WHERE  EXISTS (SELECT FROM votes v WHERE v.post_id = p.id);

In Postgres and with multiple entries on the n-side like you probably have, it's generally faster than count(DISTINCT post_id):

SELECT count(DISTINCT p.id) AS post_ct
FROM   posts p
JOIN   votes v ON v.post_id = p.id;

The more rows per post there are in votes, the bigger the difference in performance. Test with EXPLAIN ANALYZE.

count(DISTINCT post_id) has to read all rows, sort or hash them, and then only consider the first per identical set. EXISTS will only scan votes (or, preferably, an index on post_id) until the first match is found.

If every post_id in votes is guaranteed to be present in the table posts (referential integrity enforced with a foreign key constraint), this short form is equivalent to the longer form:

SELECT count(DISTINCT post_id) AS post_ct
FROM   votes;

May actually be faster than the EXISTS query with no or few entries per post.

The query you had works in simpler form, too:

SELECT count(*) AS post_ct
FROM  (
    SELECT FROM posts 
    JOIN   votes ON votes.post_id = posts.id 
    GROUP  BY posts.id
    ) sub;

Benchmark

To verify my claims I ran a benchmark on my test server with limited resources. All in a separate schema:

Test setup

Fake a typical post / vote situation:

CREATE SCHEMA y;
SET search_path = y;

CREATE TABLE posts (
  id   int PRIMARY KEY
, post text
);

INSERT INTO posts
SELECT g, repeat(chr(g%100 + 32), (random()* 500)::int)  -- random text
FROM   generate_series(1,10000) g;

DELETE FROM posts WHERE random() > 0.9;  -- create ~ 10 % dead tuples

CREATE TABLE votes (
  vote_id serial PRIMARY KEY
, post_id int REFERENCES posts(id)
, up_down bool
);

INSERT INTO votes (post_id, up_down)
SELECT g.* 
FROM  (
   SELECT ((random()* 21)^3)::int + 1111 AS post_id  -- uneven distribution
        , random()::int::bool AS up_down
   FROM   generate_series(1,70000)
   ) g
JOIN   posts p ON p.id = g.post_id;

All of the following queries returned the same result (8093 of 9107 posts had votes).
I ran 4 tests with EXPLAIN ANALYZE ant took the best of five on Postgres 9.1.4 with each of the three queries and appended the resulting total runtimes.

1. As is.

2. After ..

   ANALYZE posts;
   ANALYZE votes;
   

3. After ..

   CREATE INDEX foo on votes(post_id);
   

4. After ..

   VACUUM FULL ANALYZE posts;
   CLUSTER votes using foo;
   

count(*) ... WHERE EXISTS

1. 253 ms
2. 220 ms
3. 85 ms -- winner (seq scan on posts, index scan on votes, nested loop)
4. 85 ms

count(DISTINCT x) - long form with join

1. 354 ms
2. 358 ms
3. 373 ms -- (index scan on posts, index scan on votes, merge join)
4. 330 ms

count(DISTINCT x) - short form without join

1. 164 ms
2. 164 ms
3. 164 ms -- (always seq scan)
4. 142 ms

Best time for original query in question:

• 353 ms

For simplified version:

• 348 ms

@wildplasser's query with a CTE uses the same plan as the long form (index scan on posts, index scan on votes, merge join) plus a little overhead for the CTE. Best time:

• 366 ms

Index-only scans in the upcoming PostgreSQL 9.2 can improve the result for each of these queries, most of all for EXISTS.

Related, more detailed benchmark for Postgres 9.5 (actually retrieving distinct rows, not just counting):

• Select first row in each GROUP BY group?

I think there is an another way to understand it.

For a np.array,if we want eliminate columns we use axis = 1; if we want eliminate rows, we use axis = 0.

np.mean(np.array(np.ones(shape=(3,5,10))),axis = 0).shape # (5,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = 1).shape # (3,10)
np.mean(np.array(np.ones(shape=(3,5,10))),axis = (0,1)).shape # (10,)

For pandas object, axis = 0 stands for row-wise operation and axis = 1 stands for column-wise operation. This is different from numpy by definition, we can check definitions from numpy.doc and pandas.doc

Turns out there is a shutdown, but this must be initiated from another thread.

This solution worked for me: https://stackoverflow.com/a/22533929/573216

In Linux:

java -version

In Windows:

java.exe -version

If you need more info about the JVM you can call the executable with the parameter -XshowSettings:properties. It will show a lot of System Properties. These properties can also be accessed by means of the static method System.getProperty(String) in a Java class. As example this is an excerpt of some of the properties that can be obtained:

$ java -XshowSettings:properties -version
[...]
java.specification.version = 1.7
java.vendor = Oracle Corporation
java.vendor.url = http://java.oracle.com/
java.vendor.url.bug = http://bugreport.sun.com/bugreport/
java.version = 1.7.0_95
[...]

So if you need to access any of these properties from Java code you can use:

System.getProperty("java.specification.version");
System.getProperty("java.vendor");
System.getProperty("java.vendor.url");
System.getProperty("java.version");

Take into account that sometimes the vendor is not exposed as clear as Oracle or IBM. For example,

$ java version
"1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

HotSpot is what Oracle calls their implementation of the JVM. Check this list if the vendor does not seem to be shown with -version.

The CSS :active state means the active state of the clicked link - the moment when you clicked on it, but not released the mouse button yet, for example. It doesn't know which page you're on and can't apply any styles to the menu items.

To fix your problem you have to create a class and add it manually to the current page's menu:

a.active { color: #f00 }

<ul>
    <li><a href="index.php" class="active">HOME</a></li>
    <li><a href="two.php">PORTFOLIO</a></li>
    <li><a href="three.php">ABOUT</a></li>
    <li><a href="four.php">CONTACT</a></li>
    <li><a href="five.php">SHOP</a></li>
</ul>

For me this is the best way:

<form id="myForm">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br><br>
  <input type="button" onclick="myFunction()" value="Reset form">
</form>

<script>
function myFunction() {
    document.getElementById("myForm").reset();
}
</script>

You can make an empty commit with git commit --allow-empty, but that will not allow you to commit an empty folder structure as git does not know or care about folders as objects themselves -- just the files they contain.

The accepted answer worked for me, but I needed to dig a little deeper to fix the problems with the back button.

What I noticed is that if I link to a page using <a ui-sref="page({x: 1})">, then remove the query string using $location.search('x', null), I don't get an extra entry in my browser history, so the back button takes me back to where I started. Although I feel like this is wrong because I don't think that Angular should automatically remove this history entry for me, this is actually the desired behaviour for my particular use-case.

The problem is that if I link to the page using <a href="/page/?x=1"> instead, then remove the query string in the same way, I do get an extra entry in my browser history, so I have to click the back button twice to get back to where I started. This is inconsistent behaviour, but actually this seems more correct.

I can easily fix the problem with href links by using $location.search('x', null).replace(), but then this breaks the page when you land on it via a ui-sref link, so this is no good.

After a lot of fiddling around, this is the fix I came up with:

In my app's run function I added this:

$rootScope.$on('$locationChangeSuccess', function () {
    $rootScope.locationPath = $location.path();
});

Then I use this code to remove the query string parameter:

$location.search('x', null);

if ($location.path() === $rootScope.locationPath) {
    $location.replace();
}

to get distance between two points try this code..

public static float GetDistanceFromCurrentPosition(double lat1,double lng1, double lat2, double lng2)
 {
        double earthRadius = 3958.75;

        double dLat = Math.toRadians(lat2 - lat1);

        double dLng = Math.toRadians(lng2 - lng1);

        double a = Math.sin(dLat / 2) * Math.sin(dLat / 2)
                + Math.cos(Math.toRadians(lat1))
                * Math.cos(Math.toRadians(lat2)) * Math.sin(dLng / 2)
                * Math.sin(dLng / 2);

        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));

        double dist = earthRadius * c;

        int meterConversion = 1609;

        return new Float(dist * meterConversion).floatValue();

    }

If you are defining a constant to be shared among all the instances of the class, use static const. If the constant is specific to each instance, just use const (but note that all constructors of the class must initialize this const member variable in the initialization list).

Here's an awesome/really crappy way of extending multiple classes. I'm utilizing a couple functions that Babel put into my transpiled code. The function creates a new class that inherits class1, and class1 inherits class2, and so on. It has its issues, but a fun idea.

var _typeof = typeof Symbol === 'function' && typeof Symbol.iterator === 'symbol' ? function (obj) {
  return typeof obj
} : function (obj) {
  return obj && typeof Symbol === 'function' && obj.constructor === Symbol ? 'symbol' : typeof obj
}

function _inherits (subClass, superClass) {
  if (typeof superClass !== 'function' && superClass !== null) {
    throw new TypeError('Super expression must either be null or a function, not ' + (
      typeof superClass === 'undefined' ? 'undefined' : _typeof(superClass)))
  }
  subClass.prototype = Object.create(
    superClass && superClass.prototype,
    {
      constructor: {
        value: subClass,
        enumerable: false,
        writable: true,
        configurable: true
      }
    })
  if (superClass) {
    Object.setPrototypeOf
    ? Object.setPrototypeOf(subClass, superClass)
    : subClass.__proto__ = superClass.__proto__  // eslint-disable-line no-proto
  }
}

function _m (...classes) {
  let NewSuperClass = function () {}
  let c1 = NewSuperClass
  for (let c of classes) {
    _inherits(c1, c)
    c1 = c
  }
  return NewSuperClass
}

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

You can do this for webkit:

#text2::-webkit-input-placeholder::before {
    color:#666;
    content:"Line 1\A Line 2\A Line 3\A";
}

Try the JavaScript in operator.

if ('key' in myObj)

And the inverse.

if (!('key' in myObj))

Be careful! The in operator matches all object keys, including those in the object's prototype chain.

Use myObj.hasOwnProperty('key') to check an object's own keys and will only return true if key is available on myObj directly:

myObj.hasOwnProperty('key')

Unless you have a specific reason to use the in operator, using myObj.hasOwnProperty('key') produces the result most code is looking for.

Use Perl's URI::Escape module and uri_escape function in the second line of your bash script:

...

value="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$2")"
...

Edit: Fix quoting problems, as suggested by Chris Johnsen in the comments. Thanks!

Wikipedia says:

Method overriding, in object oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

In detail, when you have an object foo that has a void hello() function:

class foo {
    virtual void hello(); // Code : printf("Hello!");
}

A child of foo, will also have a hello() function:

class bar : foo {
    // no functions in here but yet, you can call
    // bar.hello()
}

However, you may want to print "Hello Bar!" when hello() function is being called from a bar object. You can do this using override

class bar : foo {
    virtual void hello() override; // Code : printf("Hello Bar!");
}

Honestly, this took hours to get this fixed. Finally only one thing worked a reconfirmation to solution provided by "Basheer AL-MOMANI". Which is just putting statement

   @RenderSection("scripts", required: false)

within _Layout.cshtml file after all <script></script> elements and also commenting the jquery script in the same file. Secondly, I had to add

 $.noConflict();

within jquery function call at another *.cshtml file as:

 $(document).readyfunction () {
          $.noConflict();
          $("#example1").DataTable();
         $('#example2').DataTable({
              "paging": true,
              "lengthChange": false,
              "searching": false,
              "ordering": true,
              "info": true,
              "autoWidth": false,
          });

        });

Sometime would be better use name of parent class instead name of table:

# Refers to the current class
self.class.unscoped.where(self.class.primary_key => id).update_all(created _at: timestamp)

For example "Person" base class, subclasses (and database tables) "Client" and "Seller" Instead using:

Client.where(self.class.primary_key => id).update_all(created _at: timestamp)
Seller.where(self.class.primary_key => id).update_all(created _at: timestamp)

You can use object of base class by this way:

person.class.unscoped.where(self.class.primary_key => id).update_all(created _at: timestamp)
