in SQL*Plus you could also use a REFCURSOR variable:

SQL> VARIABLE x REFCURSOR
SQL> DECLARE
  2   V_Sqlstatement Varchar2(2000);
  3  BEGIN
  4   V_Sqlstatement := 'SELECT * FROM DUAL';
  5   OPEN :x for v_Sqlstatement;
  6  End;
  7  /

Just create a file my.ini file in installation dir and have the below config as part of this file to solve this permanently.

The important needs to be inside the ;

td.rule2 div {     background-color: #ffff00 !important; } 

in fact i believe this should override it

td.rule2 { background-color: #ffff00 !important; } 

#include <algorithm>        // std::search
#include <string>
using std::search; using std::count; using std::string;

int main() {
    string mystring = "The needle in the haystack";
    string str = "needle";
    string::const_iterator it;
    it = search(mystring.begin(), mystring.end(), 
                str.begin(), str.end()) != mystring.end();

    // if string is found... returns iterator to str's first element in mystring
    // if string is not found... returns iterator to mystring.end()

if (it != mystring.end())
    // string is found
else
    // not found

return 0;
}

Based on Laravel docs for raw queries I was able to get count for a select field to work with this code in the product model.

public function scopeShowProductCount($query)
{
    $query->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))
          ->groupBy('pid')
          ->orderBy('count_pid', 'desc');
}

This facade worked to get the same result in the controller:

$products = DB::table('products')->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))->groupBy('pid')->orderBy('count_pid', 'desc')->get();

The resulting dump for both queries was as follows:

#attributes: array:2 [
  "pid" => "1271"
  "count_pid" => 19
],
#attributes: array:2 [
  "pid" => "1273"
  "count_pid" => 12
],
#attributes: array:2 [
  "pid" => "1275"
  "count_pid" => 7
]

Matlab and Scilab languages offer a simpler and more elegant syntax than Python for the question you're asking, so I think the best you can do is to mimic Matlab/Scilab by using the Numpy package in Python. By doing this the solution to your problem is very concise and elegant:

from numpy import *
property_a = array([545., 656., 5.4, 33.])
property_b = array([ 1.2,  1.3, 2.3, 0.3])
good_objects = [True, False, False, True]
good_indices = [0, 3]
property_asel = property_a[good_objects]
property_bsel = property_b[good_indices]

Numpy tries to mimic Matlab/Scilab but it comes at a cost: you need to declare every list with the keyword "array", something which will overload your script (this problem doesn't exist with Matlab/Scilab). Note that this solution is restricted to arrays of number, which is the case in your example.

Yes, remove the trailing / and (at least in ubuntu 11.04) all the paths given must be relative or full path. You can't mix absolute and relative paths in the same command.

sudo tar -czvf 2011.10.24.tar.gz ./start-directory --exclude "home/user/start-directory/logs"

will not exclude logs directory but

sudo tar -czvf 2011.10.24.tar.gz ./start-directory --exclude "./start-directory/logs"

will work

You may want to consider using Java EE, which includes the javax.servlet.* packages. If you require a specific version of the servlet api, for instance to target a specific web application server, you will probably want the Java EE version which matches, see this version table.

PHP is not what you are looking for, check out mod_rewrite

This will work as long as the image you want to rotate is already in your Properties resources folder.

In Partial Class:

Bitmap bmp2;

OnLoad:

 bmp2 = new Bitmap(Tycoon.Properties.Resources.save2);
            pictureBox6.SizeMode = PictureBoxSizeMode.StretchImage;
            pictureBox6.Image = bmp2;

Button or Onclick

private void pictureBox6_Click(object sender, EventArgs e)
        {
            if (bmp2 != null)
            {
                bmp2.RotateFlip(RotateFlipType.Rotate90FlipNone);
                pictureBox6.Image = bmp2;
            }
        }

The problem was the table width. I had used width: 100% for the table. The table columns are adjusted automatically after removing the width tag.

I had the same error, although in my case the problem was with the formatting of the DESTINATION path. The comments above are correct with respect to debugging the path string formatting, but there seems to be a bug in the File.Copy exception reporting where it still throws back the SOURCE path instead of the DESTINATION path. So don't forget to look here as well.

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.

ref: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

When not told otherwise commands take over the foreground. You only have one "foreground" process running in a single shell session. The & symbol instructs commands to run in a background process and immediately returns to the command line for additional commands.

sh my_script.sh &

A background process will not stay alive after the shell session is closed. SIGHUP terminates all running processes. By default anyway. If your command is long-running or runs indefinitely (ie: microservice) you need to pr-pend it with nohup so it remains running after you disconnect from the session:

nohup sh my_script.sh &

EDIT: There does appear to be a gray area regarding the closing of background processes when & is used. Just be aware that the shell may close your process depending on your OS and local configurations (particularly on CENTOS/RHEL): https://serverfault.com/a/117157.

If it were me, I would avoid any risky revision editing and do the following instead:

1. Create a new branch on the SHA where 222 was committed, basically as a bookmark.

2. Switch back to the main branch. In it, revert commit 222.

3. Push all the commits that have been made, which will push commit 111 only, because 222 was reverted.

4. Work on the branch from step #1 if needed. Merge from the trunk to it as needed to keep it up to date. I wouldn't bother with stash.

When it's time for the changes in commit 222 to go in, that branch can be merged to trunk.

Diagrams are back as of the June 11 2019 release

Download latest

as stated:

Yes, we’ve heard the feedback; Database Diagrams is back.

SQL Server Management Studio (SSMS) 18.1 is now generally available

?? Latest Version Does Not Included It ??

Sadly, the last version of SSMS to have database diagrams as a feature was version v17.9.

Since that version, the newer preview versions starting at v18.* have, in their words "...feature has been deprecated".

Hope is not lost though, for one can still download and use v17.9 to use database diagrams which as an aside for this question is technically not a ER diagramming tool.

As of this writing it is unclear if the release version of 18 will have the feature, I hope so because it is a feature I use extensively.

You can do that using FileInfo class:

FileInfo fi = new FileInfo("path");
var created = fi.CreationTime;
var lastmodified = fi.LastWriteTime;

Or you can delete the /build folder under your /app-project folder manually if you cannot run flutter command.

Note that the mode of opening files is 'a' or some other have alphabet 'a' will also make error because of the overwritting.

pointer = open('makeaafile.txt', 'ab+')
tes = pickle.load(pointer, encoding='utf-8')

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

You can use a common (generic) method to read attribute over a given MemberInfo

public static bool TryGetAttribute<T>(MemberInfo memberInfo, out T customAttribute) where T: Attribute {
                var attributes = memberInfo.GetCustomAttributes(typeof(T), false).FirstOrDefault();
                if (attributes == null) {
                    customAttribute = null;
                    return false;
                }
                customAttribute = (T)attributes;
                return true;
            }

In case you want jquery validate to auto pick validations on dynamically added items, you can simply remove and add validation on the whole form like below

//remove validations on entire form
$("#yourFormId")
    .removeData("validator")
    .removeData("unobtrusiveValidation");

//Simply add it again
$.validator
    .unobtrusive
    .parse("#yourFormId");

You either have to make the method Shared or use an instance of the class General:

Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)

or

General.updateDynamics(get_prospect.dynamicsID)

Public Shared Sub updateDynamics(dynID As Int32)
    ' ... '
End Sub

Shared(VB.NET)

simple and best way to use date function

example

SELECT * FROM 
data 
WHERE date(datetime) = '2009-10-20' 

OR

SELECT * FROM 
data 
WHERE date(datetime ) >=   '2009-10-20'  && date(datetime )  <= '2009-10-20'

I found the above answer giving an error with Oracle SQL, you also must use square brackets, below;

SQL> SELECT Q'[Paddy O'Reilly]' FROM DUAL;

Result: Paddy O'Reilly

If your x and y coords are not on a grid then you need to interpolate your x,y,z surface onto one. You can do this with kriging using any of the geostatistics packages (geoR, gstat, others) or simpler techniques such as inverse distance weighting.

I'm guessing the 'interp' function you mention is from the akima package. Note that the output matrix is independent of the size of your input points. You could have 10000 points in your input and interpolate that onto a 10x10 grid if you wanted. By default akima::interp does it onto a 40x40 grid:

require(akima)
require(rgl)

x = runif(1000)
y = runif(1000)
z = rnorm(1000)
s = interp(x,y,z)
> dim(s$z)
[1] 40 40
surface3d(s$x,s$y,s$z)

That'll look spiky and rubbish because its random data. Hopefully your data isnt!

In angular v10 I did something like this, first created a master.scss file and included the following variables:

master.scss file:

$theme: blue;

$button_color: red;

$label_color: gray;

Then I imported the master.scss file in my style.scss at the top:

style.scss file:

@use './master' as m;

Make sure you import the master.scss at the top.

m is an alias for the namespace;

Use @use instead of @import according to the official docs below:

https://sass-lang.com/documentation/at-rules/import

Then in your styles.scss file you can use any variable which is defined in master.scss like below:

someClass {

   backgroud-color: m.$theme;

   color: m.$button_color;

}

Hope it 'll help...

Happy Coding :)

Another alternative to simulating a F5 key press would be to simply host the WebBrowser control in the Window Forms application. You use the WebBrowser.Navigate method to load your web page and then use a standard Timer and on each tick of the timer you just re-Navigate to the url which will reload the page.

I solved it programmatically using this code:

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(Color.parseColor("#FFFFFF"), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

Revision 1:

Starting from API 23 (Marshmallow) the drawable resource abc_ic_ab_back_mtrl_am_alpha is changed to abc_ic_ab_back_material.

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:

 public class ProgramViwer : Form{
  public ProgramViwer()
  {
       InitializeComponent();
       Load += new EventHandler(ProgramViwer_Load);
  }
  private void ProgramViwer_Load(object sender, System.EventArgs e)
  {
       formPanel.Controls.Clear();
       formPanel.Controls.Add(wel);
  }
}

@jh314 is correct. In AndroidManifest.xml,

 <application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"></application>

In style.xml

  <!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/red</item>
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

the item name must be colorAccent,it decides the application's widgets default color.

But if you want to change the color in code,Maybe @aknay's answer is correct.

The proper way to remove a cookie is to set the max age to 0 and add the cookie back to the HttpServletResponse object.

Most people don't realize or forget to add the cookie back onto the response object. By doing that it will expire and remove the cookie immediately.

...retrieve cookie from HttpServletRequest
cookie.setMaxAge(0);
response.addCookie(cookie);

As explained in the section 9 of the official ECMA specification (http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) in JSON, the following chars have to be escaped:

• U+0022 (", the quotation mark)
• U+005C (\, the backslash or reverse solidus)
• U+0000 to U+001F (the ASCII control characters)

In addition, in order to safely embed JSON in HTML, the following chars have to be also escaped:

• U+002F (/)
• U+0027 (')
• U+003C (<)
• U+003E (>)
• U+0026 (&)
• U+0085 (Next Line)
• U+2028 (Line Separator)
• U+2029 (Paragraph Separator)

Some of the above characters can be escaped with the following short escape sequences defined in the standard:

• \" represents the quotation mark character (U+0022).
• \\ represents the reverse solidus character (U+005C).
• \/ represents the solidus character (U+002F).
• \b represents the backspace character (U+0008).
• \f represents the form feed character (U+000C).
• \n represents the line feed character (U+000A).
• \r represents the carriage return character (U+000D).
• \t represents the character tabulation character (U+0009).

The other characters which need to be escaped will use the \uXXXX notation, that is \u followed by the four hexadecimal digits that encode the code point.

The \uXXXX can be also used instead of the short escape sequence, or to optionally escape any other character from the Basic Multilingual Plane (BMP).

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

Laravel documentation example:

git pull https://github.com/laravel/docs.git 5.8

based on the command format:

git pull origin <branch>

$(info your_text) : Information. This doesn't stop the execution.

$(warning your_text) : Warning. This shows the text as a warning.

$(error your_text) : Fatal Error. This will stop the execution.

An answer to Kandha problem above :

It throws the "java.io.IOException service not available" i already gave those permission and include the library...i can get map view...it throws that IOException at geocoder...

I just added a catch IOException after the try and it solved the problem

    catch(IOException ioEx){
        return null;
    }

This method of selection is built-in and well covered in the Vim help. It covers XML tags and more.

See :help text-objects.

You can use bind method to attach function to several events. Just pass the event names and the handler function as in this code:

$('#foo').bind('mouseenter mouseleave', function() {
  $(this).toggleClass('entered');
});

Another option is to use chaining support of jquery api.

You can get the version of the jquery by simply printing object.jquery, the object can be any object created by you using $.

For example: if you have created a <div> element as following

var divObj = $("div");

then by printing divObj.jquery will show you the version like 1.7.1

Basically divObj inherits all the property of $() or jQuery() i.e if you try to print jQuery.fn.jquery will also print the same version like 1.7.1

try

html, body {
  overflow-x:hidden 
} 

instead of just

body {
  overflow-x:hidden 
}

I had the same scenario occuring..Very basic report, the SP (which only takes in 1 param) was taking 5 seconds to bring back 10K records, yet the report would take 6 minutes to run. According to profiler and the RS ExecutionLogStorage table, the report was spending all it's time on the query. Brian S.'s comment led me to the solution..I simply added WITH RECOMPILE before the AS statement in the SP, and now the report time pretty much matches the SP execution time.

If you want to get any element that has part of a URL in their href attribute you could use:

$( 'a[href*="google.com"]' );

This will select all elements with a href that contains google.com, for example:

• http://google.com
• http://www.google.com
• https://www.google.com/#q=How+to+get+element+by+href+in+jquery%3F

As stated by @BalusC in the comments below, it will also match elements that have google.com at any position in the href, like blahgoogle.com.

you can try to get it in a lot of ways :

1.Using media="bogus" and a <link> at the foot

<head>
    <!-- unimportant nonsense -->
    <link rel="stylesheet" href="style.css" media="bogus">
</head>
<body>
    <!-- other unimportant nonsense, such as content -->
    <link rel="stylesheet" href="style.css">
</body>

2.Inserting DOM in the old way

<script type="text/javascript">
(function(){
  var bsa = document.createElement('script');
     bsa.type = 'text/javascript';
     bsa.async = true;
     bsa.src = 'https://s3.buysellads.com/ac/bsa.js';
  (document.getElementsByTagName('head')[0]||document.getElementsByTagName('body')[0]).appendChild(bsa);
})();
</script>

3.if you can try plugins you could try loadCSS

<script>
  // include loadCSS here...
  function loadCSS( href, before, media ){ ... }
  // load a file
  loadCSS( "path/to/mystylesheet.css" );
</script>

We store latitude/longitude X 1,000,000 in our oracle database as NUMBERS to avoid round off errors with doubles.

Given that latitude/longitude to the 6th decimal place was 10 cm accuracy that was all we needed. Many other databases also store lat/long to the 6th decimal place.

The result is undefined since $.ajax runs an asynchronous operation. Meaning that return status gets executed before the $.ajax operation finishes with the request.

You may use Promise to have a syntax which feels synchronous.

function doSomething() { 
    return new Promise((resolve, reject) => {
        $.ajax({
            url:'action.php',
            type: "POST",
            data: dataString,
            success: function (txtBack) { 
                if(txtBack==1) {
                    resolve(1);
                } else {
                    resolve(0);
                }
            },
            error: function (jqXHR, textStatus, errorThrown) {
                reject(textStatus);
            }
        });
    });
}

You can call the promise like this

doSomething.then(function (result) {
    console.log(result);
}).catch(function (error) {
    console.error(error);
});

or this

(async () => {
    try {
        let result = await doSomething();
        console.log(result);
    } catch (error) {
        console.error(error);
    }
})();

Currently using Visual Studio Code and the command to disable tslint is

/* tslint:disable */

Something to note. The disable above disables ALL tslint rules on that page. If you want to disable a specific rule you can specify one/multiple rules.

/* tslint:disable comment-format */
/* tslint:disable:rule1 rule2 rule3 etc.. */

Or enable a rule

/* tslint:enable comment-format */

html

<remove  ng-repeat-start="itemGroup in Groups" ></remove>
   html stuff in here including inner repeating loops if you want
<remove  ng-repeat-end></remove>

add an angular.js directive

//remove directive
(function(){
    var remove = function(){

        return {    
            restrict: "E",
            replace: true,
            link: function(scope, element, attrs, controller){
                element.replaceWith('<!--removed element-->');
            }
        };

    };
    var module = angular.module("app" );
    module.directive('remove', [remove]);
}());

for a brief explanation,

ng-repeat binds itself to the <remove> element and loops as it should, and because we have used ng-repeat-start / ng-repeat-end it loops a block of html not just an element.

then the custom remove directive places the <remove> start and finish elements with <!--removed element-->

In combination with what Guffa described, you could use the technique described in Explanation of <script type = "text/template"> ... </script> to store the HTML document in a special script element (see the link for an explanation on how this works). That's a lot easier than storing the HTML document in a string.

From the documentation:

Precision in Comparisons The Equals method should be used with caution, because two apparently equivalent values can be unequal due to the differing precision of the two values. The following example reports that the Double value .3333 and the Double returned by dividing 1 by 3 are unequal.

...

Rather than comparing for equality, one recommended technique involves defining an acceptable margin of difference between two values (such as .01% of one of the values). If the absolute value of the difference between the two values is less than or equal to that margin, the difference is likely to be due to differences in precision and, therefore, the values are likely to be equal. The following example uses this technique to compare .33333 and 1/3, the two Double values that the previous code example found to be unequal.

So if you really need a double, you should use the techique described on the documentation. If you can, change it to a decimal. It' will be slower, but you won't have this type of problem.

All the answers so far don't address the trailing concern:

Is there an efficient method when there are hundreds of revisions after the one to be deleted?

The steps follow, but for reference, let's assume the following history:

[master] -> [hundreds-of-commits-including-merges] -> [C] -> [R] -> [B]

C: commit just following the commit to be removed (clean)

R: The commit to be removed

B: commit just preceding the commit to be removed (base)

Because of the "hundreds of revisions" constraint, I'm assuming the following pre-conditions:

1. there is some embarrassing commit that you wish never existed
2. there are ZERO subsequent commits that actually depend on that embarassing commit (zero conflicts on revert)
3. you don't care that you will be listed as the 'Committer' of the hundreds of intervening commits ('Author' will be preserved)
4. you have never shared the repository
   • or you actually have enough influence over all the people who have ever cloned history with that commit in it to convince them to use your new history
   • and you don't care about rewriting history

This is a pretty restrictive set of constraints, but there is an interesting answer that actually works in this corner case.

Here are the steps:

1. git branch base B
2. git branch remove-me R
3. git branch save
4. git rebase --preserve-merges --onto base remove-me

If there are truly no conflicts, then this should proceed with no further interruptions. If there are conflicts, you can resolve them and rebase --continue or decide to just live with the embarrassment and rebase --abort.

Now you should be on master that no longer has commit R in it. The save branch points to where you were before, in case you want to reconcile.

How you want to arrange everyone else's transfer over to your new history is up to you. You will need to be acquainted with stash, reset --hard, and cherry-pick. And you can delete the base, remove-me, and save branches

var foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";

Thanks for this post, it helped me a lot.

Dunno if it can help but I had the issue and thanks to you I found what I think is another way to solve it based on this boolean equivalence:

"A or B" is the same as "not(not A and not B)"

Thus:

IF [%var%] == [1] OR IF [%var%] == [2] ECHO TRUE

Becomes:

IF not [%var%] == [1] IF not [%var%] == [2] ECHO FALSE

Using pip2 worked for me:

!pip2 install geocoder
...
import geocoder
g = geocoder.google('Mountain View, CA')
g.latlng
[37.3860517, -122.0838511]

I came up with a class factory to support this functionality. Pass in any combination of either fields or classes you want to exclude.

public class GsonFactory {

    public static Gson build(final List<String> fieldExclusions, final List<Class<?>> classExclusions) {
        GsonBuilder b = new GsonBuilder();
        b.addSerializationExclusionStrategy(new ExclusionStrategy() {
            @Override
            public boolean shouldSkipField(FieldAttributes f) {
                return fieldExclusions == null ? false : fieldExclusions.contains(f.getName());
            }

            @Override
            public boolean shouldSkipClass(Class<?> clazz) {
                return classExclusions == null ? false : classExclusions.contains(clazz);
            }
        });
        return b.create();

    }
}

To use, create two lists (each is optional), and create your GSON object:

static {
 List<String> fieldExclusions = new ArrayList<String>();
 fieldExclusions.add("id");
 fieldExclusions.add("provider");
 fieldExclusions.add("products");

 List<Class<?>> classExclusions = new ArrayList<Class<?>>();
 classExclusions.add(Product.class);
 GSON = GsonFactory.build(null, classExclusions);
}

private static final Gson GSON;

public String getSomeJson(){
    List<Provider> list = getEntitiesFromDatabase();
    return GSON.toJson(list);
}

Try this, it works for both node and the browser.

isNode = (typeof exports !== 'undefined') &&
(typeof module !== 'undefined') &&
(typeof module.exports !== 'undefined') &&
(typeof navigator === 'undefined' || typeof navigator.appName === 'undefined') ? true : false,
asyncIt = (isNode ? function (func) {
  process.nextTick(function () {
    func();
  });
} : function (func) {
  setTimeout(func, 5);
});

This is quite simple. Just follow these instruction which I am going to tell you:

Like you are having multiple activities, to go from one activity to another. You might be using the intent like this:

Intent i1 = new Intent(this, AnotherActivity);
startActivity(i1) 

You have just to add finish(); after starting the intent activity on each and every activity from start to end, for example,

Intent i1=new Intent(this, AnotherActivity);
startActivity(i1) 
finish();

So whenever you will click that exit button which is using finish() or System.exit(0) that must close your application completely.

if (isset($_POST['submit'])) {

for($i = 0; $i<= 3; $i++){

    if(isset($_POST['books'][$i]))

        $book .= ' '.$_POST['books'][$i];
}

You can use /* tslint:disable-next-line */ to locally disable tslint. However, as this is a compiler error disabling tslint might not help.

You can always temporarily cast $ to any:

delete ($ as any).summernote.options.keyMap.pc.TAB

which will allow you to access whatever properties you want.

Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:

if (false) {
    // @ts-ignore: Unreachable code error
    console.log("hello");
}

Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any instead as that better expresses intent.

var table = new DataTable();    
using (var da = new SqlDataAdapter("SELECT * FROM mytable", "connection string"))
{      
    da.Fill(table);
}

My guess is that RAND_MAX is equal to INT_MAX and so you're overflowing it to a negative.

Just do this:

r = ((double) rand() / (RAND_MAX)) + 1;

Or even better, use C++11's random number generators.

Starting with SQL2017 you can use STRING_SPLIT and do this:

declare @myList nvarchar(MAX)
set @myList = '1,2,3,4'
select * from myTable where myColumn in (select value from STRING_SPLIT(@myList,','))

I kinda disagree with the accepted answer. Sometimes an application architecture doesn't want you to mess with the array id, or makes it inconvenient. For instance, I use CakePHP quite a lot, and a database query returns the primary key as a value in each record, very similar to the above.

Assuming the array is not stupidly large, I would use array_filter. This will create a copy of the array, minus the records you want to remove, which you can assign back to the original array variable.

Although this may seem inefficient it's actually very much in vogue these days to have variables be immutable, and the fact that most php array functions return a new array rather than futzing with the original implies that PHP kinda wants you to do this too. And the more you work with arrays, and realize how difficult and annoying the unset() function is, this approach makes a lot of sense.

Anyway:

$my_array = array_filter($my_array, 
                         function($el) { 
                            return $el["value"]!="Completed" && $el!["value"]!="Marked as Spam"; 
                         });

You can use whatever inclusion logic (eg. your id field) in the embedded function that you want.

add jdk8 or higher version at JAVA_HOME and path.

add JAVA_HOME add C:\ProgramFiles\Java\jdk1.8.0_201

For Path =>

add %MAVEN_HOME%\bin

and finally restart your pc.

Other option. See that Python default importlib.reload will just reimport the library passed as an argument. It won't reload the libraries that your lib import. If you changed a lot of files and have a somewhat complex package to import, you must do a deep reload.

If you have IPython or Jupyter installed, you can use a function to deep reload all libs:

from IPython.lib.deepreload import reload as dreload
dreload(foo)

If you don't have Jupyter, install it with this command in your shell:

pip3 install jupyter

I found one really interesting article on git rebase vs merge, thought of sharing it here

• If you want to see the history completely same as it happened, you should use merge. Merge preserves history whereas rebase rewrites it.
• Merging adds a new commit to your history
• Rebasing is better to streamline a complex history, you are able to change the commit history by interactive rebase.

You need to install it manually.

$ npm i @angular/core -s

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

I have also gone through this error and sharing how i got rid off to it.

In my case below line existed in web.config of webapi project but there was not package reference in package.config file.

Code in Web.config in Webapi Project

<dependentAssembly>
    <assemblyIdentity name="System.Runtime" publicKeyToken="B03F5F7F11D50A3A" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.1.2.0" newVersion="4.3.0" />
</dependentAssembly>

Code I Added in packages.config file in web api project Before closing of element.

<package id="System.Runtime" version="4.3.0" targetFramework="net461" />

Another Solution Worked in My Case:

Another Sure short that may work in case you copied project to another Computer system that may have little different package versions that you can try changing assembly version to version given in error on website / webapi when you run it. Like in this case as given in question Version needed is '4.1.0.0' so simply try changing current version in web.config to version shown in error as below

Error:

Could not load file or assembly 'System.Runtime, Version=4.1.0.0' or one of its dependencies

It looks necessary to put a SET IDENTITY_INSERT Database.dbo.Baskets ON; before every SQL INSERT sending batch.

You can send several INSERT ... VALUES ... commands started with one SET IDENTITY_INSERT ... ON; string at the beginning. Just don't put any batch separator between.

I don't know why the SET IDENTITY_INSERT ... ON stops working after the sending block (for ex.: .ExecuteNonQuery() in C#). I had to put SET IDENTITY_INSERT ... ON; again at the beginning of next SQL command string.

Marker already has unique id

marker.__gm_id

Google Maps actually uses signed values to represent the position:

• Latitude : max/min 90.0000000 to -90.0000000

• Longitude : max/min 180.0000000 to -180.0000000

So if you want to work with Coordinates in your projects you would need DECIMAL(10,7) ie. for SQL.

If you really want a regex, you can use this one:

str.matches(".*([ \t]).*")

In the sense that everything matching this regex is not a valid xml tag name:

if(str.matches(".*([ \t]).*")) 
      print "the input string is not valid"

sortedWith + compareBy (taking a vararg of lambdas) do the trick:

val sortedList = list.sortedWith(compareBy({ it.age }, { it.name }))

You can also use the somewhat more succinct callable reference syntax:

val sortedList = list.sortedWith(compareBy(Person::age, Person::name))

If you look at this url: http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javadb/

this part of the schema may be what you are looking for.

 ID          INTEGER NOT NULL 
                PRIMARY KEY GENERATED ALWAYS AS IDENTITY 
                (START WITH 1, INCREMENT BY 1),

Is the problem with SUM(billableDuration)? To find out, try commenting out that line and see if it works.

It could be that the sum is exceeding the maximum int. If so, try replacing it with SUM(CAST(billableDuration AS BIGINT)).

$query= $this->m_general->get('users' , array('id'=> $id ));
echo $query[''];

is ok ;)

If it's any help to anyone, give permission to "IIS_IUSRS" group.

Note that if you can't find "IIS_IUSRS", try prepending it with your server's name, like "MySexyServer\IIS_IUSRS".

Andrew Bullock solution works just fine, I just wanted to show you mine and add a warning.

//Works great

$('#<%= radBuffetCapacity.ClientID %> input').click(function (e) {
   var val = $('#<%= radBuffetCapacity.ClientID %>').find('input:checked').val();
   //Do whatever
});

//Warning - works in firefox but not IE8 .. used this for some time before a noticing that it didnt work in IE8... used to everything working in all browsers with jQuery when working in one.

$('#<%= radBuffetCapacity.ClientID %>').change(function (e) {
   var val = $('#<%= radBuffetCapacity.ClientID %>').find('input:checked').val();
   //Do whatever
});

You can use the following function:

 DESCRIBE TABLE <itab-Name> LINES <variable>

After the call, variable contains the number of rows of the internal table .

You can use some code like this, you can adjust a height and width as per your need

    protected void button_Click(object sender, EventArgs e)
    {
        // open a pop up window at the center of the page.
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
    }

Virtual methods CAN be overridden by deriving classes, but need an implementation in the base class (the one that will be overridden)

Pure virtual methods have no implementation the base class. They need to be defined by derived classes. (So technically overridden is not the right term, because there's nothing to override).

Virtual corresponds to the default java behaviour, when the derived class overrides a method of the base class.

Pure Virtual methods correspond to the behaviour of abstract methods within abstract classes. And a class that only contains pure virtual methods and constants would be the cpp-pendant to an Interface.

If anyone else is on this question, when using include('somepath.php'); and that file contains a function, the var must be declared there as well. The inclusion of $var=$var; won't always work. Try running these:

one.php:

<?php
    $vars = array('stack','exchange','.com');

    include('two.php'); /*----- "paste" contents of two.php */

    testFunction(); /*----- execute imported function */
?>

two.php:

<?php
    function testFunction(){ 
        global $vars; /*----- vars declared inside func! */
        echo $vars[0].$vars[1].$vars[2];
    }
?>

Just to demonstrate the changes that editor.renderWhitespace : none||boundary||all will do to your VSCode I added this screenshot:

The branch which you are tryin to merge may not be identified by you git at present so perform git branch and see if the branch which you want to merge exists are not, if not then perform git pull and now if you do git branch, the branch will be visible now, and now you perform git merge <BranchName>

Because "ReflectionClass" can be version depend just use the follow:

if(class_basename(get_class($object)) == 'Name') {
... do this ...
}

or even clear

if(class_basename(ClassName::class) == 'ClassName') {
... do this ...
}

You can use signals to control nginx.

According to documentation, you need to send HUP signal to nginx master process.

HUP - changing configuration, keeping up with a changed time zone (only for FreeBSD and Linux), starting new worker processes with a new configuration, graceful shutdown of old worker processes

Check the documentation here: http://nginx.org/en/docs/control.html

You can send the HUP signal to nginx master process PID like this:

kill -HUP $( cat /var/run/nginx.pid )

The command above reads the nginx PID from /var/run/nginx.pid. By default nginx pid is written to /usr/local/nginx/logs/nginx.pid but that can be overridden in config. Check your nginx.config to see where it saves the PID.

You simply cannot. DataFrames, same as other distributed data structures, are not iterable and can be accessed using only dedicated higher order function and / or SQL methods.

You can of course collect

for row in df.rdd.collect():
    do_something(row)

or convert toLocalIterator

for row in df.rdd.toLocalIterator():
    do_something(row)

and iterate locally as shown above, but it beats all purpose of using Spark.

var bordT = $('img').outerWidth() - $('img').innerWidth();
var paddT = $('img').innerWidth() - $('img').width();
var margT = $('img').outerWidth(true) - $('img').outerWidth();

var formattedBord = bordT + 'px';
var formattedPadd = paddT + 'px';
var formattedMarg = margT + 'px';

Check the jQuery API docs for information on each:

• outerWidth
• innerWidth
• width

Here's the edited jsFiddle showing the result.

You can perform the same type of operations for the Height to get its margin, border, and padding.

An interface defines public instance properties and methods. Fields are typically private, or at the most protected, internal or protected internal (the term "field" is typically not used for anything public).

As stated by other replies you can define a base class and define a protected property which will be accessible by all inheritors.

One oddity is that an interface can in fact be defined as internal but it limits the usefulness of the interface, and it is typically used to define internal functionality that is not used by other external code.

I think using the STL method 'remove_if' from could help to prevent some weird issue when trying to attempt to delete the object that is wrapped by the iterator.

This solution may be less efficient.

Let's say we have some kind of container, like vector or a list called m_bullets:

Bullet::Ptr is a shared_pr<Bullet>

'it' is the iterator that 'remove_if' returns, the third argument is a lambda function that is executed on every element of the container. Because the container contains Bullet::Ptr, the lambda function needs to get that type(or a reference to that type) passed as an argument.

 auto it = std::remove_if(m_bullets.begin(), m_bullets.end(), [](Bullet::Ptr bullet){
    // dead bullets need to be removed from the container
    if (!bullet->isAlive()) {
        // lambda function returns true, thus this element is 'removed'
        return true;
    }
    else{
        // in the other case, that the bullet is still alive and we can do
        // stuff with it, like rendering and what not.
        bullet->render(); // while checking, we do render work at the same time
        // then we could either do another check or directly say that we don't
        // want the bullet to be removed.
        return false;
    }
});
// The interesting part is, that all of those objects were not really
// completely removed, as the space of the deleted objects does still 
// exist and needs to be removed if you do not want to manually fill it later 
// on with any other objects.
// erase dead bullets
m_bullets.erase(it, m_bullets.end());

'remove_if' removes the container where the lambda function returned true and shifts that content to the beginning of the container. The 'it' points to an undefined object that can be considered garbage. Objects from 'it' to m_bullets.end() can be erased, as they occupy memory, but contain garbage, thus the 'erase' method is called on that range.

I'm not sure if this is what you ask, but you can check gradle version of your project here in android studio:

(left pane must be in project view, not android for this path) app->gradle->wrapper->gradle-wrapper.properties

it has a line like this, indicating the gradle version:

distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-all.zip

There is also a table at the end of this page that shows gradle and gradle plug-in versions supported by each android studio version. (you can check your android studio by checking help->about as you may already know)

The introduction of some new testing facilities in Spring 4.2.RC1 lets one write Spring integration tests that don't rely on the SpringJUnit4ClassRunner. Check out this part of the documentation.

In your case you could write your Spring integration test and still use mocks like this:

@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration("test-app-ctx.xml")
public class FooTest {

    @ClassRule
    public static final SpringClassRule SPRING_CLASS_RULE = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    @Autowired
    @InjectMocks
    TestTarget sut;

    @Mock
    Foo mockFoo;

    @Test
    public void someTest() {
         // ....
    }
}

Yes, it's possible. But first read, "What happens when I change my username?"

To change your username, click your profile picture in the top right corner, then click Settings. On the left side, click Account. Then click Change username.

When you want keep colorful icon - Workaround
Add pixel with slightly different color into icon.
In my case a have black icon with shades and light. When added dark blue pixel it works.

Detailed designs are a waste of time, and if an engineer needs them in order to do a decent job, then it's not worth employing them!

OK, so a couple of ideas are thrown together here:

1) the old idea of waterfall development where you supposedly did all your design up front, resulting in some glorified extremely detailed class diagrams, sequence diagrams etc. etc., was a complete waste of time. As I once said to a colleague, I'll be done with design once the code is finished. Which I think is what agile is partly a recognition of - that the code is the design, and that any decent developer is continually refactoring. This of course, makes the idea that your class diagrams are out of date laughable - they always will be.

2) management often thinks that you can usefully take a poor engineer and use them as a 'code monkey' - in other words they're not particularly talented, but heck - can't you use them to write some code. Well.. no! If you have to spend so much time writing detailed specs that you're basically specifying the code, then it will be quicker to write it yourself. You're not saving any time. If a developer isn't smart enough to use their own imagination and judgement they're not worth employing. (Note, I'm not talking about junior engineers who are able to learn. Plenty of 'senior engineers' fall into this category.)

All,

Here a little bit twist with mysql-community-server 5.7 I share some steps, how to reset mysql5.7 root password or set password. it will work centos7 and RHEL7 as well.

step1. 1st stop your databases

service mysqld stop

step2. 2nd modify /etc/my.cnf file add "skip-grant-tables"

vi /etc/my.cnf

[mysqld] skip-grant-tables

step3. 3rd start mysql

service mysqld start

step4. select mysql default database

mysql -u root

mysql>use mysql;

step4. set a new password

mysql> update user set authentication_string=PASSWORD("yourpassword") where User='root';

step5 restart mysql database

service mysqld restart

 mysql -u root -p

enjoy :)

Please forgive me if I'm wrong. And I have to admit upfront that I haven't done any research on these 2 terms. Anyway...

Emulation is to mimic something with detailed known results, whatever the internal behaviors actually are. We only try to get things done and don't care much about what goes on inside.

Simulation, on the other hand, is to mimic something with some known behaviors to study something not being known yet.

my 2cents

Pattern pattern = Pattern.compile("^[a-zA-Z0-9]*$");
Matcher matcher = pattern.matcher("Teststring123");
if(matcher.matches()) {
     // yay! alphanumeric!
}

Try

$ git diff --stat --color master..branchName

This will give you more info about each change, while still using the same number of lines.

You can also flip the branches to get an even clearer picture of the difference if you were to merge the other way:

$ git diff --stat --color branchName..master

Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

In Postgres, you can also use the special DISTINCT ON (expression) syntax:

SELECT DISTINCT ON (cname) 
    cname, wmname, avg
FROM 
    makerar 
ORDER BY 
    cname, avg DESC ;

With the latest version (2.8) of the Maven Dependency Plugin, downloading an artifact from the Maven Central Repository is as simple as:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=groupId:artifactId:version[:packaging[:classifier]]

where groupId:artifactId:version, etc. are the Maven coordinates

An example, tested with Maven 2.0.9, Maven 2.2.1, and Maven 3.0.4:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=org.hibernate:hibernate-entitymanager:3.4.0.GA:jar:sources

(Thanks to Pascal Thivent for providing his wonderful answer in the first place. I am adding another answer, because it wouldn't fit in a comment and it would be too extensive for an edit.)

There is a simple work around. The alert only comes up when you have a large amount of data in your clipboard. Just copy a random cell before you close the workbook and it won't show up anymore!

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

background-image:url('image/img2.jpg'); 
background-repeat:repeat-x;

Use some image for internal image and use this.

You can use the Core/index function in a given context, for example you can check the index of the TD in it's parent TR to get the column number, and you can check the TR index on the Table, to get the row number:

$('td').click(function(){
  var col = $(this).parent().children().index($(this));
  var row = $(this).parent().parent().children().index($(this).parent());
  alert('Row: ' + row + ', Column: ' + col);
});

Check a running example here.

Alternatively, use:

forfiles /s /m *.png /c "cmd /c echo @path"

The forfiles command is available in Windows Vista and up.

It isn't possible as DateTime is immutable. The same discussion is available here: How to change time in datetime?

I fixed this issue by using Product > Clean Build Folder (CommandShiftK), which makes a new clean build, really odd.

You can now use Object.assign(target, ...sources). Following your example, you could use it like this:

class Foo {
  name: string;
  getName(): string { return this.name };
}

let fooJson: string = '{"name": "John Doe"}';
let foo: Foo = Object.assign(new Foo(), JSON.parse(fooJson));

console.log(foo.getName()); //returns John Doe

Object.assign is part of ECMAScript 2015 and is currently available in most modern browsers.

##########################################################################
# Description
#   Encode data according to
#       RFC 1738: "Uniform Resource Locators (URL)" and
#       RFC 1866: "Hypertext Markup Language - 2.0" (HTML)
#
#   This encoding is used i.e. for the MIME type
#   "application/x-www-form-urlencoded"
#
# Notes
#    o  The default behaviour is not to encode the line endings. This
#   may not be what was intended, because the result will be
#   multiple lines of output (which cannot be used in an URL or a
#   HTTP "POST" request). If the desired output should be one
#   line, use the "-l" option.
#
#    o  The "-l" option assumes, that the end-of-line is denoted by
#   the character LF (ASCII 10). This is not true for Windows or
#   Mac systems, where the end of a line is denoted by the two
#   characters CR LF (ASCII 13 10).
#   We use this for symmetry; data processed in the following way:
#       cat | urlencode -l | urldecode -l
#   should (and will) result in the original data
#
#    o  Large lines (or binary files) will break many AWK
#       implementations. If you get the message
#       awk: record `...' too long
#        record number xxx
#   consider using GNU AWK (gawk).
#
#    o  urlencode will always terminate it's output with an EOL
#       character
#
# Thanks to Stefan Brozinski for pointing out a bug related to non-standard
# locales.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

for some reason I couldn't get it to work with the outer join.

So I used:

SELECT * from t1 where not Id in (SELECT DISTINCT t2.id from t2)

When including files in PHP, it acts like the code exists within the file they are being included from. Imagine copy and pasting the code from within each of your included files directly into your index.php. That is how PHP works with includes.

So, in your example, since you've set a variable called $name in your front.inc file, and then included both front.inc and end.inc in your index.php, you will be able to echo the variable $name anywhere after the include of front.inc within your index.php. Again, PHP processes your index.php as if the code from the two files you are including are part of the file.

When you place an echo within an included file, to a variable that is not defined within itself, you're not going to get a result because it is treated separately then any other included file.

In other words, to do the behavior you're expecting, you will need to define it as a global.

DISTINCT is the keyword you're looking for.

In MSSQL, copying unique rows from a table to another can be done like this:

SELECT DISTINCT column_name
INTO newTable
FROM srcTable

The column_name is the column you're searching the unique values from.

Tested and works.

Workaround....

In VS 2015 Professional (and probably other versions). Go to Tools / Options / Environment / Fonts and Colours. In the "Show Settings For" drop-down, select "CodeLens" Choose the smallest font you can find e.g. Calibri 6. Change the foreground colour to your editor foreground colour (say "White") Click OK.

for this approach, you will need to add system.IO to your references by adding the next line of code below the other references near the top of the c# file(where the other using ****.** stand).

using System.IO;

this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))

both should be quite easy to understand and use.

    string pathToFile = "";//to save the location of the selected object
    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        OpenFileDialog theDialog = new OpenFileDialog();
        theDialog.Title = "Open Text File";
        theDialog.Filter = "TXT files|*.txt";
        theDialog.InitialDirectory = @"C:\";
        if (theDialog.ShowDialog() == DialogResult.OK)
        {
            MessageBox.Show(theDialog.FileName.ToString());
            pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object

        }

        if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
        {
            //method1
            string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
            string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();

            //method2
            string text = "";
            using(StreamReader sr =new StreamReader(pathToFile))
            {
                text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
            }
        }
    }

To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.

to add the data to your class you can use the constructor to add the data like:

  public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
        {
            EmployeeNum = EMPLOYEENUM;
            Name = NAME;
            Address = ADRESS;
            Wage = WAGE;
            Hours = HOURS;
        }

or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).

If you are using CentOS, then you need to use

1. yum install python34-devel.x86_64
2. yum groupinstall -y 'development tools'
3. pip3 install mysql-connector
4. pip install mysqlclient

To parse a date, look at Date::Parse in CPAN.

Easiest way to export Excel to Html table

$file_name ="file_name.xls";
$excel_file="Your Html Table Code";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file_name");
echo $excel_file;

You could try Trevor, which uses Docker to run your Travis build.

From its description:

I often need to run tests for multiple versions of Node.js. But I don't want to switch versions manually using n/nvm or push the code to Travis CI just to run the tests.

That's why I created Trevor. It reads .travis.yml and runs tests in all versions you requested, just like Travis CI. Now, you can test before push and keep your git history clean.

mylist = [1,2,3]

def multiple_appends(listname, *element):
    listname.extend(element)

multiple_appends(mylist, 4, 5, "string", False)
print(mylist)

OUTPUT:

[1, 2, 3, 4, 5, 'string', False]

In Angular UI Bootstrap 0.13.X, tooltip-html-unsafe has been deprecated. You should now use tooltip-html and $sce.trustAsHtml() to accomplish a tooltip with html.

For Hibernate 5.2 and above, use CriteriaBuilder as follows

CriteriaBuilder builder = sessionFactory.getCriteriaBuilder();
CriteriaQuery<Cat> query = builder.createQuery(Cat.class);
Root<Cat> rootCat = query.from(Cat.class);
Join<Cat,Mother> joinMother = rootCat.join("mother");  // <-attribute name
Join<Mother,Kind> joinMotherKind = joinMother.join("kind");
query.select(rootCat).orderBy(builder.asc(joinMotherKind.get("value")));
Query<Cat> q = sessionFactory.getCurrentSession().createQuery(query);
List<Cat> cats = q.getResultList();

I always assumed that banned characters in Windows filenames meant that all exotic characters would also be outlawed. The inability to use ?, / and : in particular irked me. One day I discovered that it was virtually only those chars which were banned. Other Unicode characters may be used. So the nearest Unicode characters to the banned ones I could find were identified and MS Word macros were made for them as Alt-?, Alt-: etc. Now I form the filename in Word, using the substitute chars, and copy it to the Windows filename. So far I have had no problems.

Here are the substitute chars (Alt - the decimal Unicode) :

? Alt-8432
/ Alt-8260
? Alt-8421
| Alt-8739
? Alt-11622 ? Alt-11162
? Alt-8253 ? Alt 4961 " Alt-8246 " Alt-8243

As a test I formed a filename using all of those chars and Windows accepted it.

This is what I put as a menu option where I made a button on a JFrame to display another JFrame. I wanted only the new frame to be visible, and not to destroy the one behind it. I initially hid the first JFrame, while the new one became visible. Upon closing of the new JFrame, I disposed of it followed by an action of making the old one visible again.

Note: The following code expands off of Ravinda's answer and ng is a JButton:

ng.addActionListener((ActionEvent e) -> {
    setVisible(false);
    JFrame j = new JFrame("NAME");
    j.setVisible(true);
    j.addWindowListener(new java.awt.event.WindowAdapter() {
        @Override
        public void windowClosing(java.awt.event.WindowEvent windowEvent) {
            setVisible(true);
        }
    });
});

Ignoring newlines is ignoring security and good coding. wnoise had the only good answer. Here is a variation on his that puts the filenames in an array $x

while IFS= read -rd ''; do 
    x+=("${REPLY#* }"); 
done < <(find . -maxdepth 1 -printf '%T@ %p\0' | sort -r -z -n )

The default value for a GUID is empty. (eg: 00000000-0000-0000-0000-000000000000)

This can be invoked using Guid.Empty or new Guid()

If you want a new GUID, you use Guid.NewGuid()

My steps:

1. Delete the pods folder and the 'Pods' file.
2. Type "pod install" into Terminal.
3. Type "pod update" into Terminal.

In addition to making sure "Build Active Architectures" was set to YES as mentioned in previous answers, this was what had done it for me.

Often in Node.js applications a .json is needed. With TypeScript 2.9, --resolveJsonModule allows for importing, extracting types from and generating .json files.

While doing my own server side JS experimentation I ended up using teajs. It conforms to common.js, is based on V8 AND is the only project that I know of that provides 'mod_teajs' apache server module.

In my opinion Node.js server is not production ready and lacks too many features - Apache is battle tested and the right way to do SSJS.

From ggplot 2.2.0 labels can easily be stacked by using position = position_stack(vjust = 0.5) in geom_text.

ggplot(Data, aes(x = Year, y = Frequency, fill = Category, label = Frequency)) +
  geom_bar(stat = "identity") +
  geom_text(size = 3, position = position_stack(vjust = 0.5))

Also note that "position_stack() and position_fill() now stack values in the reverse order of the grouping, which makes the default stack order match the legend."

Answer valid for older versions of ggplot:

Here is one approach, which calculates the midpoints of the bars.

library(ggplot2)
library(plyr)

# calculate midpoints of bars (simplified using comment by @DWin)
Data <- ddply(Data, .(Year), 
   transform, pos = cumsum(Frequency) - (0.5 * Frequency)
)

# library(dplyr) ## If using dplyr... 
# Data <- group_by(Data,Year) %>%
#    mutate(pos = cumsum(Frequency) - (0.5 * Frequency))

# plot bars and add text
p <- ggplot(Data, aes(x = Year, y = Frequency)) +
     geom_bar(aes(fill = Category), stat="identity") +
     geom_text(aes(label = Frequency, y = pos), size = 3)

just the plain command

You can check whether the target is not your div-element and then issue another click event on the parent after which you will "return" from the handle.

$('clickable').click(function (event) {
    let div = $(event.target);
    if (! div.is('div')) {
       div.parent().click();
       return;
    }
    // Then Implement your logic here
}

Static variable in a header file:

say 'common.h' has

static int zzz;

This variable 'zzz' has internal linkage (This same variable can not be accessed in other translation units). Each translation unit which includes 'common.h' has it's own unique object of name 'zzz'.

Static variable in a class:

Static variable in a class is not a part of the subobject of the class. There is only one copy of a static data member shared by all the objects of the class.

$9.4.2/6 - "Static data members of a class in namespace scope have external linkage (3.5).A local class shall not have static data members."

So let's say 'myclass.h' has

struct myclass{
   static int zzz;        // this is only a declaration
};

and myclass.cpp has

#include "myclass.h"

int myclass::zzz = 0           // this is a definition, 
                               // should be done once and only once

and "hisclass.cpp" has

#include "myclass.h"

void f(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

and "ourclass.cpp" has

#include "myclass.h"
void g(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

So, class static members are not limited to only 2 translation units. They need to be defined only once in any one of the translation units.

Note: usage of 'static' to declare file scope variable is deprecated and unnamed namespace is a superior alternate

SQLite table names are case insensitive, but comparison is case sensitive by default. To make this work properly in all cases you need to add COLLATE NOCASE.

SELECT name FROM sqlite_master WHERE type='table' AND name='table_name' COLLATE NOCASE

You have to use parseInt() to convert

For eg.

  var z = parseInt(x) + parseInt(y);

use parseFloat() if you want to handle float value.

Thank you #DangerDave this solved my problem on Magento 2, and this is how I did

I am on a vps

root@myvps [~]# cd /var/lib/mysql/mydatabasename/

root@myvps [~]# ls

check for tables with no .frm fie (only .idb) and delete them,

rm customer_grid_flat.ibd

System will regenerate tables after running index:reindex command

My answer is focused to a extended case derived from the one exposed at top.

Suppose you have group of elements from which you want to hide the child elements except first. As an example:

<html>
  <div class='some-group'>
     <div class='child child-0'>visible#1</div>
     <div class='child child-1'>xx</div>
     <div class='child child-2'>yy</div>
  </div>
  <div class='some-group'>
     <div class='child child-0'>visible#2</div>
     <div class='child child-1'>aa</div>
     <div class='child child-2'>bb</div>
  </div>
</html>

1. We want to hide all .child elements on every group. So this will not help because will hide all .child elements except visible#1:

   $('.child:not(:first)').hide();
   

2. The solution (in this extended case) will be:

   $('.some-group').each(function(i,group){
       $(group).find('.child:not(:first)').hide();
   });
   

The last part of the ternary operator allows you to specify the increment step size. For instance, i++ means increment by 1. i+=2 is same as i=i+2,... etc. Example:

let val= [];

for (let i = 0; i < 9; i+=2) {
  val = val + i+",";
}


console.log(val);

Expected results: "2,4,6,8"

'i' can be any floating point or whole number depending on the desired step size.

Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0))). This simulates the ELSE-IF operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF formula is the value to use if the condition evaluates to true. You can't chain conditions in that manner.

ArrayList<String> city=new ArrayList<String>();
city.add("rajkot");
city.add("gondal");
city.add("rajkot");
city.add("gova");
city.add("baroda");
city.add("morbi");
city.add("gova");

HashSet<String> hashSet = new HashSet<String>();
hashSet.addAll(city);
city.clear();
city.addAll(hashSet);
Toast.makeText(getActivity(),"" + city.toString(),Toast.LENGTH_SHORT).show();

Yes you can, but instead of blank, simply return null if you don't want to render anything from component, like this:

return (null);

Another important point is, inside JSX if you are rendering element conditionally, then in case of condition=false, you can return any of these values false, null, undefined, true. As per DOC:

booleans (true/false), null, and undefined are valid children, they will be Ignored means they simply don’t render.

All these JSX expressions will render to the same thing:

<div />

<div></div>

<div>{false}</div>

<div>{null}</div>

<div>{undefined}</div>

<div>{true}</div>

Example:

Only odd values will get rendered, because for even values we are returning null.

const App = ({ number }) => {_x000D_
  if(number%2) {_x000D_
    return (_x000D_
      <div>_x000D_
        Number: {number}_x000D_
      </div>_x000D_
    )_x000D_
  }_x000D_
  _x000D_
  return (null);           //===> notice here, returning null for even values_x000D_
}_x000D_
_x000D_
const data = [1,2,3,4,5,6];_x000D_

Use group_concat method in mysql

As @luqmaan pointed out in the comments, the documentation says that the filter exists doesn't filter out empty strings as they are considered non-null values.

So adding to @DrTech's answer, to effectively filter null and empty string values out, you should use something like this:

{
    "query" : {
        "constant_score" : {
            "filter" : {
                "bool": {
                    "must": {"exists": {"field": "<your_field_name_here>"}},
                    "must_not": {"term": {"<your_field_name_here>": ""}}
                }
            }
        }
    }
}

What you're doing is pretty error-prone. Just do:

git rebase -i master

which will automatically rebase only your branch's commits onto the current latest master.

I know this is an older post, but I'm leaving this for whomever else comes looking in the future.

You can't format line breaks into an option; however, you can use the title attibute to give a mouse-over tooltip to give the full info. Use a short descriptor in the option text and give the full skinny in the title.

<option value="1" title="This is my lengthy explanation of what this selection really means, so since you only see 1 on the drop down list you really know that you're opting to elect me as King of Willywarts!  Always be sure to read the fine print!">1</option>

You need to install it in a directory in your home folder, and somehow manipulate the PYTHONPATH so that directory is included.

The best and easiest is to use virtualenv. But that requires installation, causing a catch 22. :) But check if virtualenv is installed. If it is installed you can do this:

$ cd /tmp
$ virtualenv foo
$ cd foo
$ ./bin/python

Then you can just run the installation as usual, with /tmp/foo/python setup.py install. (Obviously you need to make the virtual environment in your a folder in your home directory, not in /tmp/foo. ;) )

If there is no virtualenv, you can install your own local Python. But that may not be allowed either. Then you can install the package in a local directory for packages:

$ wget http://pypi.python.org/packages/source/s/six/six-1.0b1.tar.gz#md5=cbfcc64af1f27162a6a6b5510e262c9d
$ tar xvf six-1.0b1.tar.gz 
$ cd six-1.0b1/
$ pythonX.X setup.py   install --install-dir=/tmp/frotz

Now you need to add /tmp/frotz/pythonX.X/site-packages to your PYTHONPATH, and you should be up and running!

Note that WebMvcConfigurerAdapter is deprecated now (see WebMvcConfigurerAdapter). Due to Java 8 default methods, you only have to implement WebMvcConfigurer.

See ?substring.

x <- 'hello stackoverflow'
substring(x, 1, 1)
## [1] "h"
substring(x, 2)
## [1] "ello stackoverflow"

The idea of having a pop method that both returns a value and has a side effect of updating the data stored in x is very much a concept from object-oriented programming. So rather than defining a pop function to operate on character vectors, we can make a reference class with a pop method.

PopStringFactory <- setRefClass(
  "PopString",
  fields = list(
    x = "character"  
  ),
  methods = list(
    initialize = function(x)
    {
      x <<- x
    },
    pop = function(n = 1)
    {
      if(nchar(x) == 0)
      {
        warning("Nothing to pop.")
        return("")
      }
      first <- substring(x, 1, n)
      x <<- substring(x, n + 1)
      first
    }
  )
)

x <- PopStringFactory$new("hello stackoverflow")
x
## Reference class object of class "PopString"
## Field "x":
## [1] "hello stackoverflow"
replicate(nchar(x$x), x$pop())
## [1] "h" "e" "l" "l" "o" " " "s" "t" "a" "c" "k" "o" "v" "e" "r" "f" "l" "o" "w"

I also had the similar problem while registering myinfo.dll file in windows 7. Following work for me: Create a short cut on your desktop C:\Windows\System32\regsvr32.exe c:\windows\system32\myinfo.dll right click on the short cut just created and select as Run as administrator.

You Can Try This

$("p:first").css("background-color", "#B2E0FF").css("border", "3px solid red");

[examine all threads backtraces to find the culprit]
Even fully expanded call stack can still hide the actual offending line of code from you when you use more than one thread!

Example: One thread is iterating ruby Hash, other thread is trying to modify it. BOOM! Exception! And the problem with the stack trace you get while trying to modify 'busy' hash is that it shows you chain of functions down to the place where you're trying to modify hash, but it does NOT show who's currently iterating it in parallel (who owns it)! Here's the way to figure that out by printing stack trace for ALL currently running threads. Here's how you do this:

# This solution was found in comment by @thedarkone on https://github.com/rails/rails/issues/24627
rescue Object => boom

    thread_count = 0
    Thread.list.each do |t|
      thread_count += 1
      err_msg += "--- thread #{thread_count} of total #{Thread.list.size} #{t.object_id} backtrace begin \n"
      # Lets see if we are able to pin down the culprit
      # by collecting backtrace for all existing threads:
      err_msg += t.backtrace.join("\n")
      err_msg += "\n---thread #{thread_count} of total #{Thread.list.size} #{t.object_id} backtrace end \n"
    end

    # and just print it somewhere you like:
    $stderr.puts(err_msg)

    raise # always reraise
end

The above code snippet is useful even just for educational purposes as it can show you (like x-ray) how many threads you actually have (versus how many you thought you have - quite often those two are different numbers ;)

In activity/fragment do use this

RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
CustomRequest jsObjRequest = new CustomRequest(Method.POST, url, params, this.createRequestSuccessListener(), this.createRequestErrorListener());

requestQueue.add(jsObjRequest);

Double check your manifest, your first activity should have tag

    <intent-filter>
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

inside of activity tag.

If that doesn't work, look for target build, which located in the left of run button (green-colored play button), it should be targeting "app" folder, not a particular activity. if it doesn't targeting "app", just click it and choose "app" from drop down list.

Hope it helps!

This is the check on which it fails:

• https://github.com/scikit-learn/scikit-learn/blob/0.17.X/sklearn/utils/validation.py#L51

Which says

def _assert_all_finite(X):
    """Like assert_all_finite, but only for ndarray."""
    X = np.asanyarray(X)
    # First try an O(n) time, O(1) space solution for the common case that
    # everything is finite; fall back to O(n) space np.isfinite to prevent
    # false positives from overflow in sum method.
    if (X.dtype.char in np.typecodes['AllFloat'] and not np.isfinite(X.sum())
            and not np.isfinite(X).all()):
        raise ValueError("Input contains NaN, infinity"
                         " or a value too large for %r." % X.dtype)

So make sure that you have non NaN values in your input. And all those values are actually float values. None of the values should be Inf either.

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

Is required that you have a form?
If not, then you could use this:

<div>
    <input type="hidden" value="ServletParameter" />
    <input type="button" id="callJavaScriptServlet" onclick="callJavaScriptServlet()" />
</div>

with the following JavaScript:

function callJavaScriptServlet() {
    this.form.action = "MyServlet";
    this.form.submit();
}

Suppose we have a df_data data frame as below

> df_data
   ID MONTH-YEAR VALUE
1 110   JAN.2012  1000
2 111   JAN.2012  2000
3 121   FEB.2012  3000
4 131   FEB.2012  4000
5 141   MAR.2012  5000

To count number of rows in df_data grouped by MONTH-YEAR column, you can use:

> summary(df_data$`MONTH-YEAR`)

FEB.2012 JAN.2012 MAR.2012 
   2        2        1 

summary function will create a table from the factor argument, then create a vector for the result (line 7 & 8)

I found this network scanner in python article and wrote this short code. It does what you want! You do however need to know accessible ports for your devices. Port 22 is ssh standard and what I am using. I suppose you could loop over all ports. Some defaults are:

linux: [20, 21, 22, 23, 25, 80, 111, 443, 445, 631, 993, 995]
windows: [135, 137, 138, 139, 445]
mac: [22, 445, 548, 631]

import socket

def connect(hostname, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    socket.setdefaulttimeout(1)
    result = sock.connect_ex((hostname, port))
    sock.close()
    return result == 0

for i in range(0,255):
    res = connect("192.168.1."+str(i), 22)
    if res:
        print("Device found at: ", "192.168.1."+str(i) + ":"+str(22))

Try this -

<table align="center" style="margin: 0px auto;"></table>

A reset button doesn't need any script at all (or name or id):

<input type="reset">

and you're done. But if you really must use script, note that every form control has a form property that references the form it's in, so you could do:

<input type="button" onclick="this.form.reset();">

But a reset button is a far better choice.

I wanted to encrypt and decrypt the string as a readable string.

Here is a very simple quick example in C# Visual Studio 2019 WinForms based on the answer from @Pradip.

Right click project > properties > settings > Create a username and password setting.

Now you can leverage those settings you just created. Here I save the username and password but only encrypt the password in it's respectable value field in the user.config file.

Example of the encrypted string in the user.config file.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <userSettings>
        <secure_password_store.Properties.Settings>
            <setting name="username" serializeAs="String">
                <value>admin</value>
            </setting>
            <setting name="password" serializeAs="String">
                <value>AQAAANCMnd8BFdERjHoAwE/Cl+sBAAAAQpgaPYIUq064U3o6xXkQOQAAAAACAAAAAAAQZgAAAAEAACAAAABlQQ8OcONYBr9qUhH7NeKF8bZB6uCJa5uKhk97NdH93AAAAAAOgAAAAAIAACAAAAC7yQicDYV5DiNp0fHXVEDZ7IhOXOrsRUbcY0ziYYTlKSAAAACVDQ+ICHWooDDaUywJeUOV9sRg5c8q6/vizdq8WtPVbkAAAADciZskoSw3g6N9EpX/8FOv+FeExZFxsm03i8vYdDHUVmJvX33K03rqiYF2qzpYCaldQnRxFH9wH2ZEHeSRPeiG</value>

Use a TreeMap, although having a map "look like that" is a bit nebulous--you could also just sort the keys based on your criteria and iterate over the map, retrieving each object.

I encountered the same problem, and I fix it by creating a new subclass of UIButton and overriding the layoutSubviews: method as below :

-(void)layoutSubviews {
    [super layoutSubviews];

    // Center image
    CGPoint center = self.imageView.center;
    center.x = self.frame.size.width/2;
    center.y = self.imageView.frame.size.height/2;
    self.imageView.center = center;

    //Center text
    CGRect newFrame = [self titleLabel].frame;
    newFrame.origin.x = 0;
    newFrame.origin.y = self.imageView.frame.size.height + 5;
    newFrame.size.width = self.frame.size.width;

    self.titleLabel.frame = newFrame;
    self.titleLabel.textAlignment = UITextAlignmentCenter;

}

I think that the Angel García Olloqui's answer is another good solution, if you place all of them manually with interface builder but I'll keep my solution since I don't have to modify the content insets for each of my button.

For the most part recursion is slower, and takes up more of the stack as well. The main advantage of recursion is that for problems like tree traversal it make the algorithm a little easier or more "elegant". Check out some of the comparisons:

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

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

The technical definitions (courtesy of Wikipedia) are:

API

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

Webservice

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

you can also use this if you know the name of the primary key

SELECT
    MAX(primary_key_name) + 1
FROM
    TABLE_NAME

Don't know exactly what kind of dataset you have, so I provide general answer.

Integrated application pool mode

When an application pool is in Integrated mode, you can take advantage of the integrated request-processing architecture of IIS and ASP.NET. When a worker process in an application pool receives a request, the request passes through an ordered list of events. Each event calls the necessary native and managed modules to process portions of the request and to generate the response.

There are several benefits to running application pools in Integrated mode. First the request-processing models of IIS and ASP.NET are integrated into a unified process model. This model eliminates steps that were previously duplicated in IIS and ASP.NET, such as authentication. Additionally, Integrated mode enables the availability of managed features to all content types.

Classic application pool mode

When an application pool is in Classic mode, IIS 7.0 handles requests as in IIS 6.0 worker process isolation mode. ASP.NET requests first go through native processing steps in IIS and are then routed to Aspnet_isapi.dll for processing of managed code in the managed runtime. Finally, the request is routed back through IIS to send the response.

This separation of the IIS and ASP.NET request-processing models results in duplication of some processing steps, such as authentication and authorization. Additionally, managed code features, such as forms authentication, are only available to ASP.NET applications or applications for which you have script mapped all requests to be handled by aspnet_isapi.dll.

Be sure to test your existing applications for compatibility in Integrated mode before upgrading a production environment to IIS 7.0 and assigning applications to application pools in Integrated mode. You should only add an application to an application pool in Classic mode if the application fails to work in Integrated mode. For example, your application might rely on an authentication token passed from IIS to the managed runtime, and, due to the new architecture in IIS 7.0, the process breaks your application.

Taken from: What is the difference between DefaultAppPool and Classic .NET AppPool in IIS7?

In a ngFor loop it must be look like this:

<div class="column" *ngFor="let u of events ">
                <div class="thumb">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                </div>
                <div class="info">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                    <p>{{u.text}}</p>
                </div>
            </div>

I can tell you for Windows.

1. Install Java Extension Pack and Code Runner Extension from VS Code Extensions.

2. Edit your java home location in VS Code settings, "java.home": "C:\\Program Files\\Java\\jdk-9.0.4".

3. Check if javac is recognized in VS Code internal terminal. If this check fails, try opening VS Code as administrator.

4. Create a simple Java program in Main.java file as:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");     
    }
}

Note: Do not add package in your main class.

5. Right click anywhere on the java file and select run code.

6. Check the output in the console.

Done, hope this helps.

In addition to DannySmurf's answer of laziness, I'll add that it's to encourage you to use the constants, such as Calendar.JANUARY.

You should really not do it this way, but I just find it way too cool:

>>> replacements = {'cond1':'text1', 'cond2':'text2'}
>>> cmd = 'answer = s'
>>> for k,v in replacements.iteritems():
>>>     cmd += ".replace(%s, %s)" %(k,v)

Now, answer is the result of all the replacements in turn

again, this is very hacky and is not something that you should be using regularly. But it's just nice to know that you can do something like this if you ever need to.

You can use this class instead :) (handles even lists , nested lists and json)

public class Utility {

    public static Map<String, Object> jsonToMap(Object json) throws JSONException {

        if(json instanceof JSONObject)
            return _jsonToMap_((JSONObject)json) ;

        else if (json instanceof String)
        {
            JSONObject jsonObject = new JSONObject((String)json) ;
            return _jsonToMap_(jsonObject) ;
        }
        return null ;
    }


   private static Map<String, Object> _jsonToMap_(JSONObject json) throws JSONException {
        Map<String, Object> retMap = new HashMap<String, Object>();

        if(json != JSONObject.NULL) {
            retMap = toMap(json);
        }
        return retMap;
    }


    private static Map<String, Object> toMap(JSONObject object) throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();

        Iterator<String> keysItr = object.keys();
        while(keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = object.get(key);

            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            map.put(key, value);
        }
        return map;
    }


    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for(int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }
        return list;
    }
}

To convert your JSON string to hashmap use this :

HashMap<String, Object> hashMap = new HashMap<>(Utility.jsonToMap(response)) ;

Safest method, which I use frequently:

git clean -fd

Syntax explanation as per /docs/git-clean page:

• -f (alias: --force). If the Git configuration variable clean.requireForce is not set to false, git clean will refuse to delete files or directories unless given -f, -n or -i. Git will refuse to delete directories with .git sub directory or file unless a second -f is given.
• -d. Remove untracked directories in addition to untracked files. If an untracked directory is managed by a different Git repository, it is not removed by default. Use -f option twice if you really want to remove such a directory.

As mentioned in the comments, it might be preferable to do a git clean -nd which does a dry run and tells you what would be deleted before actually deleting it.

Link to git clean doc page: https://git-scm.com/docs/git-clean

You would be best off using collections.defaultdict (added in Python 2.5). This allows you to specify the default object type of a missing key (such as a list).

So instead of creating a key if it doesn't exist first and then appending to the value of the key, you cut out the middle-man and just directly append to non-existing keys to get the desired result.

A quick example using your data:

>>> from collections import defaultdict
>>> data = [(2010, 2), (2009, 4), (1989, 8), (2009, 7)]
>>> d = defaultdict(list)
>>> d
defaultdict(<type 'list'>, {})
>>> for year, month in data:
...     d[year].append(month)
... 
>>> d
defaultdict(<type 'list'>, {2009: [4, 7], 2010: [2], 1989: [8]})

This way you don't have to worry about whether you've seen a digit associated with a year or not. You just append and forget, knowing that a missing key will always be a list. If a key already exists, then it will just be appended to.

After trying almost every key on my keyboard:

C:\Users\Tim>cd ^
Mehr? Desktop

C:\Users\Tim\Desktop>

So it seems to be the ^ key.

Starting in C++20, it should be possible to add a full set of default comparison operators (==, <=, etc.) to a class by declaring a default three-way comparison operator ("spaceship" operator), like this:

struct Point {
    int x;
    int y;
    auto operator<=>(const Point&) const = default;
};

With a compliant C++20 compiler, adding that line to MyStruct1 and MyStruct2 may be enough to allow equality comparisons, assuming the definition of MyStruct2 is compatible.

Managed to get answer after do some google..

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

on (release) {
  getURL("http://someurl/");
}

To make the button transparent you can place a square inside it that is moved to the hit-area frame of the button.

I think it would go too far to explain into depth with pictures how to go about in stackoverflow.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security;
using System.DirectoryServices.AccountManagement;

public struct Credentials
{
    public string Username;
    public string Password;
}

public class Domain_Authentication
{
    public Credentials Credentials;
    public string Domain;

    public Domain_Authentication(string Username, string Password, string SDomain)
    {
        Credentials.Username = Username;
        Credentials.Password = Password;
        Domain = SDomain;
    }

    public bool IsValid()
    {
        using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, Domain))
        {
            // validate the credentials
            return pc.ValidateCredentials(Credentials.Username, Credentials.Password);
        }
    }
}

I just improve the groovy script from above to write the property in the root parent properties file:

import java.io.*;
String p = project.properties['env-properties-file']
File f = new File(p)
if (f.exists()) {
try{
FileWriter fstream = new FileWriter(f.getAbsolutePath())
BufferedWriter out = new BufferedWriter(fstream)
String propToSet = f.getAbsolutePath().substring(0, f.getAbsolutePath().lastIndexOf(File.separator))
if (File.separator != "/") {
propToSet = propToSet.replace(File.separator,File.separator+File.separator+File.separator)
}
out.write("jacoco.agent = " + propToSet + "/lib/jacocoagent.jar")
out.close()
}catch (Exception e){
}
}
String ret = "../"
while (!f.exists()) {
f = new File(ret + p)
ret+= "../"
}
project.properties['env-properties-file-by-groovy'] = f.getAbsolutePath()

Replying to this 4 year old post, because this seems overcomplicated to me, at least if you're hosting on IIS.

Here's how I solved it:

using System;
using System.Net;
using System.Web;
using System.Web.Http;
...
[HttpPost]
[Route("ContactForm")]
public IHttpActionResult PostContactForm([FromBody] ContactForm contactForm)
    {
        var hostname = HttpContext.Current.Request.UserHostAddress;
        IPAddress ipAddress = IPAddress.Parse(hostname);
        IPHostEntry ipHostEntry = Dns.GetHostEntry(ipAddress);
        ...

Unlike OP, this gives me the client IP and client hostname, not the server. Perhaps they've fixed the bug since then?

Try doing this :

/Employees/Employee[@id=4]/*/text()

SIMPLE XML EXAMPLE:

<school>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</school>

XSD OF ABOVE XML(Explained):

<xs:element name="school">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="firstname" type="xs:string"/>
      <xs:element name="lastname" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

Here:

xs:element : Defines an element.

xs:sequence : Denotes child elements only appear in the order mentioned.

xs:complexType : Denotes it contains other elements.

xs:simpleType : Denotes they do not contain other elements.

type: string, decimal, integer, boolean, date, time,

• In simple words, xsd is another way to represent and validate XML data with the specific type.

• With the help of extra attributes, we can perform multiple operations.

• Performing any task on xsd is simpler than xml.

You can implement your own modulus function to do that for you:

double dmod(double x, double y) {
    return x - (int)(x/y) * y;
}

Then you can simply use dmod(6.3, 2) to get the remainder, 0.3.

You have to indent the docstring after the function definition there (line 3, 4):

def print_lol(the_list):
"""this doesn't works"""
    print 'Ain't happening'

Indented:

def print_lol(the_list):
    """this works!"""
    print 'Aaaand it's happening'

Or you can use # to comment instead:

def print_lol(the_list):
#this works, too!
    print 'Hohoho'

Also, you can see PEP 257 about docstrings.

Hope this helps!
