You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

The easier way to accept all accents is this:

[A-zÀ-ú] // accepts lowercase and uppercase characters
[A-zÀ-ÿ] // as above but including letters with an umlaut (includes [ ] ^ \ × ÷)
[A-Za-zÀ-ÿ] // as above but not including [ ] ^ \
[A-Za-zÀ-ÖØ-öø-ÿ] // as above but not including [ ] ^ \ × ÷

See https://unicode-table.com/en/ for characters listed in numeric order.

I did that mistake once - embedding PDF files in HTML pages. I will suggest that you use a JavaScript library for displaying the content of the PDF. Like https://github.com/mozilla/pdf.js/

JSON in any HTML tag except <script> tag would be a mere text. Thus it's like you add a story to your HTML page.

However, about formatting, that's another matter. I guess you should change the title of your question.

Take a look at this question. Also see this page.

<div id="google_translate_element"></div><script type="text/javascript">
function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: 'fr', layout: google.translate.TranslateElement.FloatPosition.TOP_RIGHT}, 'google_translate_element');
}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

The reason 'addPane' is assigned to this is because of the <pane> directive.

The pane directive does require: '^tabs', which puts the tabs controller object from a parent directive, into the link function.

addPane is assigned to this so that the pane link function can see it. Then in the pane link function, addPane is just a property of the tabs controller, and it's just tabsControllerObject.addPane. So the pane directive's linking function can access the tabs controller object and therefore access the addPane method.

I hope my explanation is clear enough.. it's kind of hard to explain.

From the documentation:

Cmd] and Cmd[ navigates among split panes in order of use.

Use it for correct result

$dom = new DOMDocument();
$dom->loadHTML('<meta http-equiv="Content-Type" content="text/html; charset=utf-8">' . $profile);
echo $dom->saveHTML();
echo $profile;

This operation

mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8');

It is bad way, because special symbols like &lt ; , &gt ; can be in $profile, and they will not convert twice after mb_convert_encoding. It is the hole for XSS and incorrect HTML.

With SQL Developer 4.x, the language option is to be added to ..\sqldeveloper\bin\sqldeveloper.conf, rather than ..\sqldeveloper\bin\ide.conf:

# ----- MODIFICATION BEGIN -----
AddVMOption -Duser.language=en
# ----- MODIFICATION END -----

public static String readFile(String fn)   throws IOException 
{
    File f = new File(fn);

    byte[] buffer = new byte[(int)f.length()];
    FileInputStream is = new FileInputStream(fn);
    is.read(buffer);
    is.close();

    return  new String(buffer, "UTF-8"); // use desired encoding
}

just uncomment this lines in libraries/database_interface.lib.php

if (! empty($GLOBALS['collation_connection'])) {
       // PMA_DBI_query("SET CHARACTER SET 'utf8';", $link, PMA_DBI_QUERY_STORE);
       //PMA_DBI_query("SET collation_connection = '" .
       //PMA_sqlAddslashes($GLOBALS['collation_connection']) . "';", $link, PMA_DBI_QUERY_STORE);
} else {
       //PMA_DBI_query("SET NAMES 'utf8' COLLATE 'utf8_general_ci';", $link, PMA_DBI_QUERY_STORE);
 }

if you store data in utf8 without storing charset you do not need phpmyadmin to re-convert again the connection. This will work.

To expand this question into the realm of use outside of Excel s own VBA, the ActiveWindow property must be addressed as a child of the Excel.Application object.

Example for creating an Excel workbook from Access:

Using the Excel.Application object in another Office application's VBA project will require you to add Microsoft Excel 15.0 Object library (or equivalent for your own version).

Option Explicit

Sub xls_Build__Report()
    Dim xlApp As Excel.Application, ws As Worksheet, wb As Workbook
    Dim fn As String

    Set xlApp = CreateObject("Excel.Application")
    xlApp.DisplayAlerts = False
    xlApp.Visible = True

    Set wb = xlApp.Workbooks.Add
    With wb
        .Sheets(1).Name = "Report"
        With .Sheets("Report")

            'report generation here

        End With

        'This is where the Freeze Pane is dealt with
        'Freezes top row
        With xlApp.ActiveWindow
            .SplitColumn = 0
            .SplitRow = 1
            .FreezePanes = True
        End With

        fn = CurrentProject.Path & "\Reports\Report_" & Format(Date, "yyyymmdd") & ".xlsx"
        If CBool(Len(Dir(fn, vbNormal))) Then Kill fn
        .SaveAs FileName:=fn, FileFormat:=xlOpenXMLWorkbook
    End With

Close_and_Quit:
    wb.Close False
    xlApp.Quit
End Sub

The core process is really just a reiteration of previously submitted answers but I thought it was important to demonstrate how to deal with ActiveWindow when you are not within Excel's own VBA. While the code here is VBA, it should be directly transcribable to other languages and platforms.

OS version: 10.14.6 MYSQL version: 8.0.14

Goto System preferences -> MYSQL

Stop MySQL server

One option will be shown here to uninstall MYSQL 8 after stopping Mysql server

Check out jQuery.floatThead (demos available) which is very cool, can work with DataTables too, and can even work inside an overflow: auto container.

It's a very difficult problem to validate something like a name due to all the corner cases possible.

Corner Cases

• Anything anything here

Sanitize the inputs and let them enter whatever they want for a name, because deciding what is a valid name and what is not is probably way outside the scope of whatever you're doing; given the range of potential strange - and legal names is nearly infinite.

If they want to call themselves Tricyclopltz^2-Glockenschpiel, that's their problem, not yours.

I think LayeredPane is your best bet here. You would need a third panel though to contain A and B. This third panel would be the layeredPane and then panel A and B could still have a nice LayoutManagers. All you would have to do is center B over A and there is quite a lot of examples in the Swing trail on how to do this. Tutorial for positioning without a LayoutManager.

public class Main {
    private JFrame frame = new JFrame();
    private JLayeredPane lpane = new JLayeredPane();
    private JPanel panelBlue = new JPanel();
    private JPanel panelGreen = new JPanel();
    public Main()
    {
        frame.setPreferredSize(new Dimension(600, 400));
        frame.setLayout(new BorderLayout());
        frame.add(lpane, BorderLayout.CENTER);
        lpane.setBounds(0, 0, 600, 400);
        panelBlue.setBackground(Color.BLUE);
        panelBlue.setBounds(0, 0, 600, 400);
        panelBlue.setOpaque(true);
        panelGreen.setBackground(Color.GREEN);
        panelGreen.setBounds(200, 100, 100, 100);
        panelGreen.setOpaque(true);
        lpane.add(panelBlue, new Integer(0), 0);
        lpane.add(panelGreen, new Integer(1), 0);
        frame.pack();
        frame.setVisible(true);
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main();
    }

}

You use setBounds to position the panels inside the layered pane and also to set their sizes.

Edit to reflect changes to original post You will need to add component listeners that detect when the parent container is being resized and then dynamically change the bounds of panel A and B.

TL;DR

If you target modern browsers and don't have extravagant styling needs: http://jsfiddle.net/dPixie/byB9d/3/ ... Although the big four version is pretty sweet as well this version handles fluid width a lot better.

Good news everyone!

With the advances of HTML5 and CSS3 this is now possible, at least for modern browsers. The slightly hackish implementation I came up with can be found here: http://jsfiddle.net/dPixie/byB9d/3/. I have tested it in FX 25, Chrome 31 and IE 10 ...

But how?!

Simply put you have a table header, that you visually hide by making it 0px high, that also contains divs used as the fixed header. The table's container leaves enough room at the top to allow for the absolutely positioned header, and the table with scrollbars appear as you would expect.

The code above uses the positioned class to position the table absolutely (I'm using it in a popup style dialog) but you can use it in the flow of the document as well by removing the positioned class from the container.

But ...

It's not perfect. Firefox refuses to make the header row 0px (at least I did not find any way) but stubbornly keeps it at minimum 4px ... It's not a huge problem, but depending on your styling it will mess with your borders etc.

The table is also using a faux column approach where the background color of the container itself is used as the background for the header divs, that are transparent.

Summary

All in all there might be styling issues depending on your requirements, especially borders or complicated backgrounds. There might also be problems with computability, I haven't checked it in a wide variety of browsers yet (please comment with your experiences if you try it out), but I didn't find anything like it so I thought it was worth posting anyway ...

You'd have to test it but if you embedded an iframe within your page then used CSS to absolutely position the 1st row & column at 0,0 in the iframe page would that solve your problem?

Mainly join is used exclusively to join based on the index,not on the attribute names,so change the attributes names in two different dataframes,then try to join,they will be joined,else this error is raised

i had the same issues a longtime then i got the solution by the below code. please use

parent.jQuery.fancybox.close()

Only one thing needs to be done to solve the problem: upgrade TeamCity to version 8.1.x or higher because support for Visual Studio 2012/2013 and MSBuild Tools 2013 was only introduced in TeamCity 8.1. Once you've upgraded your TeamCity modify MSBuild Tools Version setting in your build step accordingly ans the problem will disappear. For more info read here: http://blog.turlov.com/2014/07/upgrade-teamcity-to-enable-support-for.html

Dude... exit() function is defined under stdlib.h

So you need to add a preprocessor.

Put include stdlib.h in the header section

Then use exit(); wherever you like but remember to put an interger number in the parenthesis of exit.

for example:

exit(0);

Many of the Python 2 implementations here will fail if there is no controlling terminal when you call this script. You can check sys.stdout.isatty() to determine if this is in fact a terminal, but that will exclude a bunch of cases, so I believe the most pythonic way to figure out the terminal size is to use the builtin curses package.

import curses
w = curses.initscr()
height, width = w.getmaxyx()

I would like to add a solution, that have helpt me to solve this problem in entity framework:

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
                .Where(x =>  x.DateTimeStart.Year == currentDateTime.Year &&
                             x.DateTimeStart.Month== currentDateTime.Month &&
                             x.DateTimeStart.Day == currentDateTime.Day
    );

I hope that it helps.

The ifelse function is best for simple logic like this.

> x <- seq(1950, 1960, 1)

    ifelse(x == 1957, 1, 0)
    ifelse(x <= 1957, 1, 0)

>  [1] 0 0 0 0 0 0 0 1 0 0 0
>  [1] 1 1 1 1 1 1 1 1 0 0 0

Also, if you want it to return character data then you can do so.

> x <- seq(1950, 1960, 1)

    ifelse(x == 1957, "foo", "bar")
    ifelse(x <= 1957, "foo", "bar")

>  [1] "bar" "bar" "bar" "bar" "bar" "bar" "bar" "foo" "bar" "bar" "bar"
>  [1] "foo" "foo" "foo" "foo" "foo" "foo" "foo" "foo" "bar" "bar" "bar"

Categorical variables with nesting...

> x <- seq(1950, 1960, 1)

    ifelse(x == 1957, "foo", ifelse(x == 1958, "bar","baz"))

>  [1] "baz" "baz" "baz" "baz" "baz" "baz" "baz" "foo" "bar" "baz" "baz"

This is the most straightforward option.

This works with Windows 10, 8.x, 7, and possibly further back:

@echo Started: %date% %time%
.
.
.
@echo Completed: %date% %time%

emplace_back conforming implementation will forward arguments to the vector<Object>::value_typeconstructor when added to the vector. I recall Visual Studio didn't support variadic templates, but with variadic templates will be supported in Visual Studio 2013 RC, so I guess a conforming signature will be added.

With emplace_back, if you forward the arguments directly to vector<Object>::value_type constructor, you don't need a type to be movable or copyable for emplace_back function, strictly speaking. In the vector<NonCopyableNonMovableObject> case, this is not useful, since vector<Object>::value_type needs a copyable or movable type to grow.

But note that this could be useful for std::map<Key, NonCopyableNonMovableObject>, since once you allocate an entry in the map, it doesn't need to be moved or copied ever anymore, unlike with vector, meaning that you can use std::map effectively with a mapped type that is neither copyable nor movable.

For version 3 of the API, this is simple and working:

var latlngList = [];
latlngList.push(new google.maps.LatLng(lat, lng));

var bounds = new google.maps.LatLngBounds();
latlngList.each(function(n) {
    bounds.extend(n);
});

map.setCenter(bounds.getCenter()); //or use custom center
map.fitBounds(bounds);

and some optional tricks:

//remove one zoom level to ensure no marker is on the edge.
map.setZoom(map.getZoom() - 1); 

// set a minimum zoom 
// if you got only 1 marker or all markers are on the same address map will be zoomed too much.
if(map.getZoom() > 15){
    map.setZoom(15);
}

Programmatically (Swift 4 & 5)

self.passwordTextField.isSecureTextEntry = true

This simple solution works, but not for deep object check.

function isset(str) {
    return window[str] !== undefined;
}

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">
  <div class="row justify-content-center align-items-center">
    <h1>Form</h1>

  <div class="row justify-content-center align-items-center h-100">
    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>
        <div class="form-group text-center">

I hope this helps someone. Thank you.

Use MouseDown event

if(e.Button == MouseButton.Right)

app.use(path, middleware) is used to call middleware function that needs to be called before the route is hit for the corresponding path. Multiple middleware functions can be invoked via an app.use.

app.use(‘/fetch’, enforceAuthentication) -> enforceAuthentication middleware fn will be called when a request starting with ‘/fetch’ is received. It can be /fetch/users, /fetch/ids/{id}, etc

Some middleware functions might have to be called irrespective of the request. For such cases, a path is not specified, and since the the path defaults to / and every request starts with /, this middleware function will be called for all requests.

app.use(() => { // Initialize a common service })

next() fn needs to be called within each middleware function when multiple middleware functions are passed to app.use, else the next middleware function won’t be called.

reference : http://expressjs.com/en/api.html#app.use

Note: The documentation says we can bypass middleware functions following the current one by calling next('route') within the current middleware function, but this technique didn't work for me within app.use but did work with app.METHOD like below. So, fn1 and fn2 were called but not fn3.

app.get('/fetch', function fn1(req, res, next)  {
    console.log("First middleware function called"); 
        next();
    }, 
    function fn2(req, res, next) {
        console.log("Second middleware function called"); 
        next("route");
    }, 
    function fn3(req, res, next) {
        console.log("Third middleware function will not be called"); 
        next();
    })

You're missing a close paren in this line:

fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494

There are three ( and only two ).
I hope This will help you.

Every SQL statement executed by the Oracle database has a cursor associated with it, which is a private work area to store processing information. Implicit cursors are implicitly created by the Oracle server for all DML and SELECT statements.

You can declare and use Explicit cursors to name the private work area, and access its stored information in your program block.

JSF 1.0 / 1.1

Just put the desired logic in the constructor of the request scoped bean associated with the JSF page.

public Bean() {
    // Do your stuff here.
}

JSF 1.2 / 2.x

Use @PostConstruct annotated method on a request or view scoped bean. It will be executed after construction and initialization/setting of all managed properties and injected dependencies.

@PostConstruct
public void init() {
    // Do your stuff here.
}

This is strongly recommended over constructor in case you're using a bean management framework which uses proxies, such as CDI, because the constructor may not be called at the times you'd expect it.

JSF 2.0 / 2.1

Alternatively, use <f:event type="preRenderView"> in case you intend to initialize based on <f:viewParam> too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct is perfectly fine too.

<f:metadata>
    <f:viewParam name="foo" value="#{bean.foo}" />
    <f:event type="preRenderView" listener="#{bean.onload}" />
</f:metadata>

public void onload() { 
    // Do your stuff here.
}

JSF 2.2+

Alternatively, use <f:viewAction> in case you intend to initialize based on <f:viewParam> too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct is perfectly fine too.

<f:metadata>
    <f:viewParam name="foo" value="#{bean.foo}" />
    <f:viewAction action="#{bean.onload}" />
</f:metadata>

public void onload() { 
    // Do your stuff here.
}

Note that this can return a String navigation case if necessary. It will be interpreted as a redirect (so you do not need a ?faces-redirect=true here).

public String onload() { 
    // Do your stuff here.
    // ...
    return "some.xhtml";
}

While I'd suggest using expect, too, for non-interactive use the normal shell commands might suffice. Telnet accepts its command on stdin, so you just need to pipe or write the commands into it:

telnet 10.1.1.1 <<EOF
remotecommand 1
remotecommand 2
EOF

(Edit: Judging from the comments, the remote command needs some time to process the inputs or the early SIGHUP is not taken gracefully by the telnet. In these cases, you might try a short sleep on the input:)

{ echo "remotecommand 1"; echo "remotecommand 2"; sleep 1; } | telnet 10.1.1.1

In any case, if it's getting interactive or anything, use expect.

I opted to use the CFURLCreateStringByAddingPercentEscapes call as given by accepted answer, however in newest version of XCode (and IOS), it resulted in an error, so used the following instead:

NSString *apiKeyRaw = @"79b|7Qd.jW=])(fv|M&W0O|3CENnrbNh4}2E|-)J*BCjCMrWy%dSfGs#A6N38Fo~";

NSString *apiKey = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)apiKeyRaw, NULL, (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8));

As per https://kb.informatica.com/solution/23/Pages/69/570664.aspx adding this property works

CryptoProtocolVersion=TLSv1.2

entering a command after you logged in can be done by going through SSH section at the bottom of putty and you should have an option Remote command (data to send to the server) separate the two commands with ;

You can simply use raw html tags like

foo <font color='red'>bar</font> foo

Be aware that this will not survive a conversion of the notebook to latex.

As there are some complaints about the deprecation of the proposed solution. They are totally valid and Scott has already answered the question with a more recent, i.e. CSS based approach. Nevertheless, this answer shows some general approach to use html tags within IPython to style markdown cell content beyond the available pure markdown capabilities.

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])

In SQL, this problem could be solved by several methods:

select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)

or join and then unpivot (possible in SQL server)

select
    df1.user_id,
    c.rating
from df1
    inner join df2 on df2.user_i = df1.user_id
    outer apply (
        select df1.rating union all
        select df2.rating
    ) as c

Second one could be written in pandas with something like:

>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
   user_id  rating
0        3      20
0        3      30

None of the above changes worked for me. Please see my worked configuration below:

I was trying to put a transparent HTML overlay over my GL view but it has always black flickering which covers my GL view. After several days trying to get rid of this flickering I found this workaround which is acceptable for me (but a shame for android).

The problem is that I need hardware acceleration for my nice CSS animations and so webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); is not an option for me.

The trick was to put a second (empty) WebView between my GL view and the HTML overlay. This dummyWebView I told to render in SW mode, and now my HTML overlays renders smooth in HW and no more black flickering.

I don't know if this works on other devices than My Acer Iconia A700, but I hope I could help someone with this.

public class MyActivity extends Activity {

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        RelativeLayout layout = new RelativeLayout(getApplication());
        setContentView(layout);

        MyGlView glView = new MyGlView(this);

        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);

        dummyWebView = new WebView(this);
        dummyWebView.setLayoutParams(params);
        dummyWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        dummyWebView.loadData("", "text/plain", "utf8");
        dummyWebView.setBackgroundColor(0x00000000);

        webView = new WebView(this);
        webView.setLayoutParams(params);
        webView.loadUrl("http://10.0.21.254:5984/ui/index.html");
        webView.setBackgroundColor(0x00000000);


        layout.addView(glView);
        layout.addView(dummyWebView);
        layout.addView(webView);
    }
}

google.maps.event.addListener(marker, 'dblclick', function () {
    var oldZoom = map.getZoom(); 
    map.setCenter(this.getPosition());
    map.setZoom(parseInt(oldZoom) + 1);
});

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

Off the top of my head, you might try using the "margin: 0 auto" for #outer rather than #inner.

I often add background-color to my DIVs to see how they're laying out on the view. That might be a good way to diagnose what's going onn here.

The server directive has to be in the http directive. It should not be outside of it.

Incase if you need detailed information, refer this.

I had the same problem with a dummy app that happened to have the same name as my final app and couldn't publish because the App Name is already in use

To fix it, instead of deleting it(which you can't) I just changed the name of the dummy app to something random and hit SAVE. Then I was able to add the new app with the proper name

This solved my issue,

Try adding parentheses around the row in table1 e.g.

DELETE 
  FROM table1
 WHERE (stn, year(datum)) IN (SELECT stn, jaar FROM table2);

The above is Standard SQL-92 code. If that doesn't work, it could be that your SQL product of choice doesn't support it.

Here's another Standard SQL approach that is more widely implemented among vendors e.g. tested on SQL Server 2008:

MERGE INTO table1 AS t1
   USING table2 AS s1
      ON t1.stn = s1.stn
         AND s1.jaar = YEAR(t1.datum)
WHEN MATCHED THEN DELETE;

Use repr()[1:-1]. In this case, the double quotes don't need to be escaped. The [-1:1] slice is to remove the single quote from the beginning and the end.

>>> x = raw_input()
I'm "stuck" :\
>>> print x
I'm "stuck" :\
>>> print repr(x)[1:-1]
I\'m "stuck" :\\

Or maybe you just want to escape a phrase to paste into your program? If so, do this:

>>> raw_input()
I'm "stuck" :\
'I\'m "stuck" :\\'

lxml provides etree.DTD

from the tests on http://lxml.de/api/lxml.tests.test_dtd-pysrc.html

...
root = etree.XML(_bytes("<b/>")) 
dtd = etree.DTD(BytesIO("<!ELEMENT b EMPTY>")) 
self.assert_(dtd.validate(root)) 

This works in awk as well.

awk '!/^$/' file

Usually, the correct way of updating certain fields in one or more model instances is to use the update() method on the respective queryset. Then you do something like this:

affected_surveys = Survey.objects.filter(
    # restrict your queryset by whatever fits you
    # ...
    ).update(active=True)

This way, you don't need to call save() on your model anymore because it gets saved automatically. Also, the update() method returns the number of survey instances that were affected by your update.

You can use the files from debug folder,however if you look at app debug informations with some inspection software,you can clearly see "Symbols File Name" which can reveals not wanted informations in path to the original exe file.

onClick="javascript:this.form.submit();">

this in div onclick don't have attribute form, you may try this.parentNode.submit() or document.forms[0].submit() will do

Also, onClick, should be onclick, some browsers don't work with onClick

Simple command to check keras version:

(py36) C:\WINDOWS\system32>python
Python 3.6.8 |Anaconda custom (64-bit) 

>>> import keras
Using TensorFlow backend.

Save this class in the file StaticDemo.java. Also you cant have more than one public classes in one file.

From PEP 8 -- Style Guide for Python Code:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. Long lines can be broken over multiple lines by wrapping expressions in parentheses. These should be used in preference to using a backslash for line continuation.

Backslashes may still be appropriate at times. For example, long, multiple with-statements cannot use implicit continuation, so backslashes are acceptable:

with open('/path/to/some/file/you/want/to/read') as file_1, \
        open('/path/to/some/file/being/written', 'w') as file_2:
    file_2.write(file_1.read())

Another such case is with assert statements.

Make sure to indent the continued line appropriately. The preferred place to break around a binary operator is after the operator, not before it. Some examples:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

PEP8 now recommends the opposite convention (for breaking at binary operations) used by mathematicians and their publishers to improve readability.

Donald Knuth's style of breaking before a binary operator aligns operators vertically, thus reducing the eye's workload when determining which items are added and subtracted.

From PEP8: Should a line break before or after a binary operator?:

Donald Knuth explains the traditional rule in his Computers and Typesetting series: "Although formulas within a paragraph always break after binary operations and relations, displayed formulas always break before binary operations"[3].

Following the tradition from mathematics usually results in more readable code:

# Yes: easy to match operators with operands
income = (gross_wages
          + taxable_interest
          + (dividends - qualified_dividends)
          - ira_deduction
          - student_loan_interest)

In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. For new code Knuth's style is suggested.

[3]: Donald Knuth's The TeXBook, pages 195 and 196

Use:

git log --graph --abbrev-commit --decorate  --first-parent <branch_name>

It is only for the target branch (of course --graph, --abbrev-commit --decorate are more polishing).

The key option is --first-parent: "Follow only the first parent commit upon seeing a merge commit" (https://git-scm.com/docs/git-log)

It prevents the commit forks from being displayed.

The following code snippet enables/disables a button depending on whether at least one checkbox on the page has been checked.

$('input[type=checkbox]').change(function () {
    $('#test > tbody  tr').each(function () {
        if ($('input[type=checkbox]').is(':checked')) {
            $('#btnexcellSelect').removeAttr('disabled');
        } else {
            $('#btnexcellSelect').attr('disabled', 'disabled');
        }
        if ($(this).is(':checked')){
            console.log( $(this).attr('id'));
         }else{
             console.log($(this).attr('id'));
         }
     });
});

It's better to try to simulate a webbrowser by yourself.You don't have to stick with Chrome or IE or else thing.

If you're using Python,you can try package pyQt4 which helps you to simulate a webbrowser. By doing this,there will not be any security reasons and you can set the webbrowser to show in full screen mode automatically.

For me texBoxName.Clear();is the best method because I have textboxs in binding and if I use other methods I do not have a good day

Mostly personal preference, though one could make the argument that NULL makes it quite obvious that the object is a pointer which currently doesn't point to anything, e.g.

void *ptr = &something;
/* lots o' code */
ptr = NULL; // more obvious that it's a pointer and not being used

IIRC, the standard does not require NULL to be 0, so using whatever is defined in <stddef.h> is probably best for your compiler.

Another facet to the argument is whether you should use logical comparisons (implicit cast to bool) or explicity check against NULL, but that comes down to readability as well.

I can confirm that I have the same bug on Windows 7 using Chrome Version 35 but I share my partial solution who is open a new tab on Chrome and showing a dialog.

For other browser when the user click on cancel automatically close the new print window.

//Chrome's versions > 34 is some bug who stop all javascript when is show a prints preview
//http://stackoverflow.com/questions/23071291/javascript-window-print-in-chrome-closing-new-window-or-tab-instead-of-cancel
if(navigator.userAgent.toLowerCase().indexOf('chrome') > -1) {
    var popupWin = window.open();
    popupWin.window.focus();
    popupWin.document.write('<!DOCTYPE html><html><head>' +
        '<link rel="stylesheet" type="text/css" href="style.css" />' +
        '</head><body onload="window.print()"><div class="reward-body">' + printContents + '</div></html>');
    popupWin.onbeforeunload = function (event) {
        return 'Please use the cancel button on the left side of the print preview to close this window.\n';
    };
}else {
    var popupWin = window.open('', '_blank', 'width=600,height=600,scrollbars=no,menubar=no,toolbar=no,location=no,status=no,titlebar=no');
    popupWin.document.write('<!DOCTYPE html><html><head>' +
        '<link rel="stylesheet" type="text/css" href="style.css" />' +
        '</head><body onload="window.print()"><div class="reward-body">' + printContents + '</div>' +
        '<script>setTimeout(function(){ window.parent.focus(); window.close() }, 100)</script></html>');
}
popupWin.document.close();

I appreciate this question and all the info with it. I have something in mind that's kind of a question and an answer when it comes to String.Index.

I'm trying to see if there is an O(1) way to access a Substring (or Character) inside a String because string.index(startIndex, offsetBy: 1) is O(n) speed if you look at the definition of index function. Of course we can do something like:

let characterArray = Array(string)

then access any position in the characterArray however SPACE complexity of this is n = length of string, O(n) so it's kind of a waste of space.

I was looking at Swift.String documentation in Xcode and there is a frozen public struct called Index. We can initialize is as:

let index = String.Index(encodedOffset: 0)

Then simply access or print any index in our String object as such:

print(string[index])

Note: be careful not to go out of bounds`

This works and that's great but what is the run-time and space complexity of doing it this way? Is it any better?

var data="your data";//ex data="id="+id;
      $.ajax({
       method : "POST",
       url : "file name",  //url: "demo.php"
       data : "data",
       success : function(result){
               //set result to div or target 
              //ex $("#divid).html(result)
        }
   });

You can also calculate correlations for all variables but exclude selected ones, for example:

mtcars <- data.frame(mtcars)
# here we exclude gear and carb variables
cors <- cor(subset(mtcars, select = c(-gear,-carb)))

Also, to calculate correlation between each variable and one column you can use sapply()

# sapply effectively calls the corelation function for each column of mtcars and mtcars$mpg
cors2 <- sapply(mtcars, cor, y=mtcars$mpg)

By default Windows defines the following prefix that is available to everyone: http://+:80/Temporary_Listen_Addresses/

So you can register your HttpListener via:

Prefixes.Add("http://+:80/Temporary_Listen_Addresses/" + Guid.NewGuid().ToString("D") + "/";

This sometimes causes problems with software such as Skype which will try to utilise port 80 by default.

You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.

I installed Eclipse and created a Java project. Created new Java file outside the 'src' directory and tried to run that. I got the same error "Editor does not contain a main type". I just moved the java file into the 'src' folder and could simply run the program. I couldn't understand what other answers were asking to try. It was so simple.

simply used the + operator. Javascript concats strings with +

First, we need GOPATH

The $GOPATH is a folder (or set of folders) specified by its environment variable. We must notice that this is not the $GOROOT directory where Go is installed.

export GOPATH=$HOME/gocode
export PATH=$PATH:$GOPATH/bin

We used ~/gocode path in our computer to store the source of our application and its dependencies. The GOPATH directory will also store the binaries of their packages.

Then check Go env

You system must have $GOPATH and $GOROOT, below is my Env:

GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/elpsstu/gocode"
GORACE=""
GOROOT="/home/pravin/go"
GOTOOLDIR="/home/pravin/go/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"

Now, you run download go package:

go get [-d] [-f] [-fix] [-t] [-u] [build flags] [packages]

Get downloads and installs the packages named by the import paths, along with their dependencies. For more details you can look here.

Public Sub LinqToSqlJoin07()
Dim q = From e In db.Employees _
        Group Join o In db.Orders On e Equals o.Employee Into ords = Group _
        From o In ords.DefaultIfEmpty _
        Select New With {e.FirstName, e.LastName, .Order = o}

ObjectDumper.Write(q) End Sub

Check http://msdn.microsoft.com/en-us/vbasic/bb737929.aspx

Use modulo

whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use

if (j % 4 == 0) 

I use this mnemonic:

• Single quotes are for strings (one thing)
• Double quotes are for tables names and column names (two things)

This is not 100% correct according to the specs, but this mnemonic helps me (human being).

You can test with jQuery if any child div has a certain class. Then by applying that class when you mouse over and out out a certain div, you can test whether your mouse is over it, even when you mouse over a different element on the page Much less code this way. I used this because I had spaces between divs in a pop-up, and I only wanted to close the pop up when I moved off of the pop up, not when I was moving my mouse over the spaces in the pop up. So I called a mouseover function on the content div (which the pop up was over), but it would only trigger the close function when I moused-over the content div, AND was outside the pop up!

$(".pop-up").mouseover(function(e)
    {
    $(this).addClass("over");
    });

$(".pop-up").mouseout(function(e)
    {
    $(this).removeClass("over");
    });


$("#mainContent").mouseover(function(e){
            if (!$(".expanded").hasClass("over")) {
            Drupal.dhtmlMenu.toggleMenu($(".expanded"));
        }
    });

For web applications there is another issue which is important and it is selecting correct configuration during application publish process.

You may build your app in debug mode, but it might happen you publish it in release mode which omptimzes code by default but IDE may mislead you since it shows debug mode while published code is in release mode. You can see details in below snapshot:

If only you want the first letter:

>>> 'hello world'.capitalize()
'Hello world'

But to capitalize each word:

>>> 'hello world'.title()
'Hello World'

Another approach to this would be to download Jan Karel Pieterse's free Open XML class module from this page: Editing elements in an OpenXML file using VBA

With this added to your VBA project, you can unzip the Excel file, use VBA to modify the XML, then use the class to rezip the files.

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

RewriteEngine, DirectoryIndex in .htaccess file of CodeIgniter apps

I just changed the .htaccess file contents and as shown in the following links answer. And tried refreshing the page (which didn't work, and couldn't find the request to my controller) it worked.

Then just because of my doubt I undone the changes I did to my .htaccess inside my public_html folder back to original .htaccess content. So it's now as follows (which is originally it was):

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]

And now also it works.

Hint: Seems like before the Rewrite Rules haven't been clearly setup within the Server context.

My file structure is as follows:

/
|- gheapp
|    |- application
|    L- system
|
|- public_html
|    |- .htaccess
|    L- index.php

And in the index.php I have set up the following paths to the system and the application:

$system_path = '../gheapp/system';
$application_folder = '../gheapp/application';

Note: by doing so, our application source code becomes hidden to the public at first.

Please, if you guys find anything wrong with my answer, comment and re-correct me!
Hope beginners would find this answer helpful.

Thanks!

If you go to C:\Windows\system32\Windowspowershell\v1.0 (and C:\Windows\syswow64\Windowspowershell\v1.0 on x64 machines) in Windows Explorer and double-click powershell.exe you will see that it opens PowerShell with a black background. The PowerShell console shows up as blue when opened from the start menu because the console properties for shortcuts to powershell.exe can be set independently from the default properties.

To set the default options, font, colors and layout, open a PowerShell console, type Alt-Space, and select the Defaults menu option.

Running start powershell from cmd.exe should start a new console with your default settings.

Alternatively we can use lxml, it support xpath and very fast!

from lxml import html, etree 

attr = html.fromstring(html_text)#passing the raw html
handles = attr.xpath('//div[@class="stylelistrow"]')#xpath exresssion to find that specific class

for each in handles:
    print(etree.tostring(each))#printing the html as string

Arrays in C++ cannot change size at runtime. For that purpose, you should use vector<int> instead.

vector<int> arr;
arr.push_back(1);
arr.push_back(2);

// arr.size() will be the number of elements in the vector at the moment.

As mentioned in the comments, vector is defined in vector header and std namespace. To use it, you should:

#include <vector>

and also, either use std::vector in your code or add

using std::vector; 

or

using namespace std;

after the #include <vector> line.

The accepted answer by Adam (flex: 1 1 0) works perfectly for flexbox containers whose width is either fixed, or determined by an ancestor. Situations where you want the children to fit the container.

However, you may have a situation where you want the container to fit the children, with the children equally sized based on the largest child. You can make a flexbox container fit its children by either:

• setting position: absolute and not setting width or right, or
• place it inside a wrapper with display: inline-block

For such flexbox containers, the accepted answer does NOT work, the children are not sized equally. I presume that this is a limitation of flexbox, since it behaves the same in Chrome, Firefox and Safari.

The solution is to use a grid instead of a flexbox.

Demo: https://codepen.io/brettdonald/pen/oRpORG

<p>Normal scenario — flexbox where the children adjust to fit the container — and the children are made equal size by setting {flex: 1 1 0}</p>

<div id="div0">
  <div>
    Flexbox
  </div>
  <div>
    Width determined by viewport
  </div>
  <div>
    All child elements are equal size with {flex: 1 1 0}
  </div>
</div>

<p>Now we want to have the container fit the children, but still have the children all equally sized, based on the largest child. We can see that {flex: 1 1 0} has no effect.</p>

<div class="wrap-inline-block">
<div id="div1">
  <div>
    Flexbox
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div2">
  <div>
    Flexbox
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>

<br><br><br><br><br><br>
<p>So let's try a grid instead. Aha! That's what we want!</p>

<div class="wrap-inline-block">
<div id="div3">
  <div>
    Grid
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div4">
  <div>
    Grid
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>

In case anyone was still looking and came across this SO post like I did.

<input type="submit" name="open" value="Open">
<input type="submit" name="close" value="Close">

def contact():
    if "open" in request.form:
        pass
    elif "close" in request.form:
        pass
    return render_template('contact.html')

Simple, concise, and it works. Don't even need to instantiate a form object.

Use SHOW VARIABLES:

show variables like 'version';

Do you need any other information except the date? If not:

SELECT DISTINCT start_date FROM table;

public class CustomCollection : List<Object>
{
    public Object this[int index]
    {
        // ...
    }
}

Judging from everything you've said, it seems like the original Odómetro string you're dealing with is encoded with ISO 8859-1, not UTF-8.

Here's why I think so:

• json_encode produced parseable output after you ran the input string through utf8_encode, which converts from ISO 8859-1 to UTF-8.
• You did say that you got "mangled" output when using print_r after doing utf8_encode, but the mangled output you got is actually exactly what would happen by trying to parse UTF-8 text as ISO 8859-1 (ó is \x63\xb3 in UTF-8, but that sequence is ó in ISO 8859-1.
• Your htmlentities hackaround solution worked. htmlentities needs to know what the encoding of the input string to work correctly. If you don't specify one, it assumes ISO 8859-1. (html_entity_decode, confusingly, defaults to UTF-8, so your method had the effect of converting from ISO 8859-1 to UTF-8.)
• You said you had the same problem in Python, which would seem to exclude PHP from being the issue.

PHP will use the \uXXXX escaping, but as you noted, this is valid JSON.

So, it seems like you need to configure your connection to Postgres so that it will give you UTF-8 strings. The PHP manual indicates you'd do this by appending options='--client_encoding=UTF8' to the connection string. There's also the possibility that the data currently stored in the database is in the wrong encoding. (You could simply use utf8_encode, but this will only support characters that are part of ISO 8859-1).

Finally, as another answer noted, you do need to make sure that you're declaring the proper charset, with an HTTP header or otherwise (of course, this particular issue might have just been an artifact of the environment where you did your print_r testing).

If you are sure that it is not a typo spelling-wise, perhaps it is a typo case-wise.

What collation are you using? Check it.

Try:

$('li.current_sub').prevAll("li.par_cat:first");

Tested it with your markup:

$('li.current_sub').prevAll("li.par_cat:first").text("woohoo");

will fill up the closest previous li.par_cat with "woohoo".

1. for error: unescaped apostrophe in string

what I found is that AAPT2 tool points to wrong row in xml, sometimes. So you should correct whole strings.xml file

In Android Studio, in problem file use :

Edit->find->replace

Then write in first field \' (or \&,>,\<,\")
in second put '(or &,>,<,")
then replace each if needed.(or "reptlace all" in case with ')
Then in first field again put '(or &,>,<,")
and in second write \'
then replace each if needed.(or "replace all" in case with ')

2. for other problematic symbols
I use to comment each next half part +rebuild until i won't find the wrong sign.

E.g. an escaped word "\update" unexpectedly drops such error :)

Method 1 (Easiest Way): If you have your image on Mac

You can drag an image from the Finder on your Mac to Simulator, and it is saved to the Saved Photos album.

Method 2: If its on any URL

To save an image from a webpage to the Photos app

1. Place the pointer on the image you want to save, and hold down the mouse button or trackpad.
2. When the menu appears, click Save Image to save the image to the Photos app in an iOS simulator.
3. The image is saved to the Saved Photos album in the Photos app.

The easiest way I've found to place objects on the left is using FlowLayout.

JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));

adding a component normally to this panel will place it on the left

My solution is:

import threading, time

def a():
    t = threading.currentThread()
    while getattr(t, "do_run", True):
    print('Do something')
    time.sleep(1)

def getThreadByName(name):
    threads = threading.enumerate() #Threads list
    for thread in threads:
        if thread.name == name:
            return thread

threading.Thread(target=a, name='228').start() #Init thread
t = getThreadByName('228') #Get thread by name
time.sleep(5)
t.do_run = False #Signal to stop thread
t.join()

Or maybe:

names = ['Jasmine', 'Alberto', 'Ross', 'dig-dog']
print ("The solution for this is about this names being sorted:",sorted(names, key=lambda name:name.lower()))

You can split them very easily using JUnit categories and Maven.
This is shown very, very briefly below by splitting unit and integration tests.

Define A Marker Interface

public interface IntegrationTest {}

Mark your test classes

Add the category annotation to the top of your test class. It takes the name of your new interface.

import org.junit.experimental.categories.Category;

@Category(IntegrationTest.class)
public class ExampleIntegrationTest{

    @Test
    public void longRunningServiceTest() throws Exception {
    }

}

Configure Maven Unit Tests

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.11</version>
    <configuration>
        <includes>
            <include>**/*.class</include>
        </includes>
        <excludedGroups>
            com.test.annotation.type.IntegrationTest
        </excludedGroups>
    </configuration>
</plugin>

When you do a mvn clean test, only your unmarked unit tests will run.

Configure Maven Integration Tests

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <includes>
            <include>**/*.class</include>
        </includes>
        <groups>
            com.test.annotation.type.IntegrationTest
        </groups>
    </configuration>
</plugin>

The configuration uses a standard execution goal to run the failsafe plugin during the integration-test phase of the build.

You can now do a mvn clean install.
This time as well as the unit tests running, the integration tests are run during the integration-test phase.

You messed up the second part of your if condition. That should be a <= 90.

Also, FYI, there is a C library function tolower that does this already:

#include <ctype.h>
#include <stdio.h>

int main() {
    putchar(tolower('A'));
}

select to_char(tran_datetime,'HH24') from test;

TO_CHAR(tran_datetime,'HH24')

Pure bash solution for comparing floats without exponential notation, leading or trailing zeros:

if [ ${FOO%.*} -eq ${BAR%.*} ] && [ ${FOO#*.} \> ${BAR#*.} ] || [ ${FOO%.*} -gt ${BAR%.*} ]; then
  echo "${FOO} > ${BAR}";
else
  echo "${FOO} <= ${BAR}";
fi

Order of logical operators matters. Integer parts are compared as numbers and fractional parts are intentionally compared as strings. Variables are split into integer and fractional parts using this method.

Won't compare floats with integers (without dot).

For the line-end thingie, refer to man git-merge:

--ignore-space-change 
--ignore-all-space 
--ignore-space-at-eol

Be sure to add autocrlf = false and/or safecrlf = false to the windows clone (.git/config)

Using git mergetool

If you configure a mergetool like this:

git config mergetool.cp.cmd '/bin/cp -v "$REMOTE" "$MERGED"'
git config mergetool.cp.trustExitCode true

Then a simple

git mergetool --tool=cp
git mergetool --tool=cp -- paths/to/files.txt
git mergetool --tool=cp -y -- paths/to/files.txt # without prompting

Will do the job

Using simple git commands

In other cases, I assume

git checkout HEAD -- path/to/myfile.txt

should do the trick

Edit to do the reverse (because you screwed up):

git checkout remote/branch_to_merge -- path/to/myfile.txt

for 32-bit Python, the installer is here. after you run the installer, you will have easy_install.exe in your \Python27\Scripts directory

if you are looking for 64-bit installers, this is an excellent resource:

http://www.lfd.uci.edu/~gohlke/pythonlibs/

the author has installers for both Setuptools and Distribute. Either one will give you easy_install.exe

Subquery is the name.

At times it's required, but good/bad depends on how it's applied.

I needed to represent PHP multidimensional array in HTML input format.

$test = [
    'a' => [
        'b' => [
            'c' => ['a', 'b']
        ]
    ],
    'b' => 'c',
    'c' => [
        'd' => 'e'
    ]
];

$flatten = function ($input, $parent = []) use (&$flatten) {
    $return = [];

    foreach ($input as $k => $v) {
        if (is_array($v)) {
            $return = array_merge($return, $flatten($v, array_merge($parent, [$k])));
        } else {
            if ($parent) {
                $key = implode('][', $parent) . '][' . $k . ']';

                if (substr_count($key, ']') != substr_count($key, '[')) {
                    $key = preg_replace('/\]/', '', $key, 1);
                }
            } else {
                $key = $k;
            }           

            $return[$key] = $v;
        }
    }

    return $return;
};

die(var_dump( $flatten($test) ));

array(4) {
  ["a[b][c][0]"]=>
  string(1) "a"
  ["a[b][c][1]"]=>
  string(1) "b"
  ["b"]=>
  string(1) "c"
  ["c[d]"]=>

}

We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups.

Random Tip

NOTE: We use an alias that overloads kafka-consumer-groups like so in our /etc/profile.d/kafka.sh:

alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\"  kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=40760

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

You could also use deconstruction and tuples and try something like this:

@foreach (var (index, member) in @Model.Members.Select((member, i) => (i, member)))
{
  <div>@index - @member.anyProperty</div>

  if(index > 0 && index % 4 == 0) { // display clear div every 4 elements
      @: <div class="clear"></div>
  }
}

For more info you can have a look at this link

You can try this: In my case i am loading menu from database based on role based access, Write the code on your every view which menu your want to active based on your view.

<script type="text/javascript">
        $(document).ready(function () {         
            $('li.active active-menu').removeClass('active active-menu');
            $('a[href="/MgtCustomer/Index"]').closest('li').addClass('active active-menu');
        });
</script>

Any - boolean function that returns true when any of object in list satisfies condition set in function parameters. For example:

List<string> strings = LoadList();
boolean hasNonEmptyObject = strings.Any(s=>string.IsNullOrEmpty(s));

Where - function that returns list with all objects in list that satisfy condition set in function parameters. For example:

IEnumerable<string> nonEmptyStrings = strings.Where(s=> !string.IsNullOrEmpty(s));

Exists - basically the same as any but it's not generic - it's defined in List class, while Any is defined on IEnumerable interface.

I know that this is an old question, but I'm surprised that no answer mentions GetDateTime:

Gets the value of the specified column as a DateTime object.

Which you can use like:

while (MyReader.Read())
{
    TextBox1.Text = MyReader.GetDateTime(columnPosition).ToString("dd/MM/yyyy");
}

String timestamp = "2019-09-18 21.42.05.000705";
String sub1 = timestamp.substring(0, 19).replace('.', ':'); 
String sub2 = timestamp.substring(19, timestamp.length());
System.out.println("Original String "+ timestamp);      
System.out.println("Replaced Value "+ sub1+sub2);

Use object to represent val/var/method to make static. You can use object instead of singleton class also. You can use companion if you wanted to make static inside of a class

object Abc{
     fun sum(a: Int, b: Int): Int = a + b
    }

If you need to call it from Java:

int z = Abc.INSTANCE.sum(x,y);

In Kotlin, ignore INSTANCE.

Yes. You need to Deep Copy your object.

I have found answers to my confusions.

There is a very important difference between the root and the alias directives. This difference exists in the way the path specified in the root or the alias is processed.

In case of the root directive, full path is appended to the root including the location part, whereas in case of the alias directive, only the portion of the path NOT including the location part is appended to the alias.

To illustrate:

Let's say we have the config

location /static/ {
    root /var/www/app/static/;
    autoindex off;
}

In this case the final path that Nginx will derive will be

/var/www/app/static/static

This is going to return 404 since there is no static/ within static/

This is because the location part is appended to the path specified in the root. Hence, with root, the correct way is

location /static/ {
    root /var/www/app/;
    autoindex off;
}

On the other hand, with alias, the location part gets dropped. So for the config

location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ?
}                            |
                             pay attention to this trailing slash

the final path will correctly be formed as

/var/www/app/static

The case of trailing slash for alias directive

There is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.

A few more places have discussed this, not conclusively though.

https://serverfault.com/questions/376162/how-can-i-create-a-location-in-nginx-that-works-with-and-without-a-trailing-slas

You cannot create a table with a name that is identical to an existing table or view in the cluster. To modify an existing table, use ALTER TABLE (link), or to drop all data currently in the table and create an empty table with the desired schema, issue DROP TABLE before CREATE TABLE.

It could be that the sequence you are creating is the culprit. In PostgreSQL, sequences are implemented as a table with a particular set of columns. If you already have the sequence defined, you should probably skip creating it. Unfortunately, there's no equivalent in CREATE SEQUENCE to the IF NOT EXISTS construct available in CREATE TABLE. By the looks of it, you might be creating your schema unconditionally, anyways, so it's reasonable to use

DROP TABLE IF EXISTS csd_relationship;
DROP SEQUENCE IF EXISTS csd_relationship_csd_relationship_id_seq;

before the rest of your schema update; In case it isn't obvious, This will delete all of the data in the csd_relationship table, if there is any

you can use InsertHelper, it is easy and fast

if you want to extract the contents of an already-loaded UIWebView, -stringByEvaluatingJavaScriptFromString. For example:

NSString  *html = [webView stringByEvaluatingJavaScriptFromString: @"document.body.innerHTML"];

Maybe you're not doing it as root?

Try sudo nginx -s reload, if it still doesn't work, you might want to try sudo pkill -HUP nginx.

To display the current branch you're on, without the other branches listed, you can do the following:

git rev-parse --abbrev-ref HEAD

Reference:

• Show just the current branch in Git (Sep 2009)

You are allowed to use IDs that start with a digit in your HTML5 documents:

The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.

There are no other restrictions on what form an ID can take; in particular, IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc.

But querySelector method uses CSS3 selectors for querying the DOM and CSS3 doesn't support ID selectors that start with a digit:

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.

Use a value like b22 for the ID attribute and your code will work.

Since you want to select an element by ID you can also use .getElementById method:

document.getElementById('22')

Private Sub CommandButton1_Click()

    Workbooks("Textfile_Receiving").Sheets("menu").Range("g1").Value = PROV.Text
    Workbooks("Textfile_Receiving").Sheets("menu").Range("g2").Value = MUN.Text
    Workbooks("Textfile_Receiving").Sheets("menu").Range("g3").Value = CAT.Text
    Workbooks("Textfile_Receiving").Sheets("menu").Range("g4").Value = Label5.Caption

    Me.Hide

    Run "filename"

End Sub

Private Sub MUN_Change()
    Dim r As Integer
    r = 2

    While Range("m" & CStr(r)).Value <> ""
        If Range("m" & CStr(r)).Value = MUN.Text Then
        Label5.Caption = Range("n" & CStr(r)).Value
        End If
        r = r + 1
    Wend

End Sub

Private Sub PROV_Change()
    If PROV.Text = "LAGUNA" Then
        MUN.Text = ""
        MUN.RowSource = "Menu!M26:M56"
    ElseIf PROV.Text = "CAVITE" Then
        MUN.Text = ""
        MUN.RowSource = "Menu!M2:M25"
    ElseIf PROV.Text = "QUEZON" Then
        MUN.Text = ""
        MUN.RowSource = "Menu!M57:M97"
    End If
End Sub

I tried a lot many things, but my drop down was inside a table and I was not able to perform a simple select operation. Only the below solution worked. Here I am highlighting drop down elem and pressing down arrow until getting the desired value -

        #identify the drop down element
        elem = browser.find_element_by_name(objectVal)
        for option in elem.find_elements_by_tag_name('option'):
            if option.text == value:
                break

            else:
                ARROW_DOWN = u'\ue015'
                elem.send_keys(ARROW_DOWN)

change your method to:

$scope.toggleChecked = function (index) {
    $scope.checked.push($scope.items[index]);
    $scope.items.splice(index, 1);
};

Working Demo

I got the error "The table/view 'dbo.vMyView' does not have a primary key defined" after I created a view in SQL server query designer. I solved the problem by using ISNULL on a column to force entity framework to use it as a primary key. You might have to restart visual studio to get the warnings to go away.

CREATE VIEW [dbo].[vMyView]
AS
SELECT ISNULL(Id, -1) AS IdPrimaryKey, Name
FROM  dbo.MyTable

If you are using this inside Codeigniter, you can use the methods:

usort($jobs, array($this->job_model, "sortJobs"));  // function inside Model
usort($jobs, array($this, "sortJobs")); // Written inside Controller.

I think this is a solution that solves your problem easily: (return true if any of the parameters is not null)

  public boolean isUserEmpty(){ 
boolean isEmpty;
isEmpty =  isEmpty = Stream.of(id,
            name)
        .anyMatch(userParameter -> userParameter != null);

return isEmpty;}

Another solution to the same task is:(you can change it to if(isEmpty==0) checks if all the parameters are null.

public boolean isUserEmpty(){  
       long isEmpty;
            isEmpty = Stream.of(id,
                    name)
                    .filter(userParameter -> userParameter != null).count();

            if (isEmpty > 0) {
                return true;
            } else {
                return false;
            }
    }

use toUpperCase() or toLowerCase() method of String class.

You need to add below code in your AppDelegate applicationDidBecomeActive method.

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];

Lets see, numeric (3,2). That means you have 3 places for data and two of them are to the right of the decimal leaving only one to the left of the decimal. 15 has two places to the left of the decimal. BTW if you might have 100 as a value I'd increase that to numeric (5, 2)

Doesn't contain @: /(^[^@]*$)/

Combining works if the intended result of combination is that any of them matching results in the whole regexp matching.

To mark a lambda async, simply prepend async before its argument list:

// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
    SQLiteUtils slu = new SQLiteUtils();
    await slu.DeleteGroupAsync(groupName);
}));

An answer from AlexGo did the trick for me:

getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
         messages.add(m);
         adapter.notifyDataSetChanged();
         getListView().setSelection(messages.size()-1);
        }
});

List Update worked for me before when the update was triggered from a GUI event, thus being in the UI thread.

However, when I update the list from another event/thread - i.e. a call from outside the app, the update would not be in the UI thread and it ignored the call to getListView. Calling the update with runOnUiThread as above did the trick for me. Thanks!!

            // C:\\databaseFileName.accdb" - location of your database 
           String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + "C:\\emp.accdb";

            // specify url, username, pasword - make sure these are valid 
            Connection conn = DriverManager.getConnection(url, "username", "password");

            System.out.println("Connection Succesfull");
         } 
         catch (Exception e) 
         {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());

          }
      }
  }

I was also facing same issue. Below are the steps to resolve it.

1. check your openssl version

openssl version

2. If your version is below

OpenSSL 1.1.1h 22 Sep 2020

3. go to below link and download latest full version of openssl. openssl windows installer
4. After installation add openssl path at the top of 'PATH' variable in system path.
5. confirm your version is latest by opening new command prompt and running command in step 1
6. Now you're ready to run the command again and this time it will work.

You can get a really nice, visual output of how your branches differ with this

git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative master..branch-X

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

We can use _.difference function to see if there is any difference or not.

function isSame(arrayOne, arrayTwo) {
   var a = _.uniq(arrayOne),
   b = _.uniq(arrayTwo);
   return a.length === b.length && 
          _.isEmpty(_.difference(b.sort(), a.sort()));
}

// examples
console.log(isSame([1, 2, 3], [1, 2, 3])); // true
console.log(isSame([1, 2, 4], [1, 2, 3])); // false
console.log(isSame([1, 2], [2, 3, 1])); // false
console.log(isSame([2, 3, 1], [1, 2])); // false

// Test cases pointed by Mariano Desanze, Thanks.
console.log(isSame([1, 2, 3], [1, 2, 2])); // false
console.log(isSame([1, 2, 2], [1, 2, 2])); // true
console.log(isSame([1, 2, 2], [1, 2, 3])); // false

I hope this will help you.

Adding example link at StackBlitz

If you would like a bash function that works both on Mac OS X and Linux:

#
# Convert one date format to another
# 
# Usage: convert_date_format <input_format> <date> <output_format>
#
# Example: convert_date_format '%b %d %T %Y %Z' 'Dec 10 17:30:05 2017 GMT' '%Y-%m-%d'
convert_date_format() {
  local INPUT_FORMAT="$1"
  local INPUT_DATE="$2"
  local OUTPUT_FORMAT="$3"
  local UNAME=$(uname)

  if [[ "$UNAME" == "Darwin" ]]; then
    # Mac OS X
    date -j -f "$INPUT_FORMAT" "$INPUT_DATE" +"$OUTPUT_FORMAT"
  elif [[ "$UNAME" == "Linux" ]]; then
    # Linux
    date -d "$INPUT_DATE" +"$OUTPUT_FORMAT"
  else
    # Unsupported system
    echo "Unsupported system"
  fi
}

# Example: 'Dec 10 17:30:05 2017 GMT' => '2017-12-10'
convert_date_format '%b %d %T %Y %Z' 'Dec 10 17:30:05 2017 GMT' '%Y-%m-%d'

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

I'm not sure if you can make a TextBlock selectable, but another option would be to use a RichTextBox - it is like a TextBox as you suggested, but supports the formatting you want.

Go for the full installation of Git for windows (with Unix tool), and bison and flex would come with it in the bin folder.

We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.

So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.

    String input = null;

    // we have to store the string, which can only be read one time, because when the
    // servlet awakens an AsyncContext, it reposts the request and returns here empty handed
    if ((input = (String) request.getAttribute("com.xp.input")) == null) {
        StringBuilder buffer = new StringBuilder();
        BufferedReader reader = request.getReader();

        String line;
        while((line = reader.readLine()) != null){
            buffer.append(line);
        }
        // reqBytes = buffer.toString().getBytes();

        input = buffer.toString();
        request.setAttribute("com.xp.input", input);
    }

    if (input == null) {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
    }       

I would use this syntax

Delete a

The problem with your solution is you're putting a scrollbar around a ListBox where you probably want to put it inside the ListBox.

If you want to force a scrollbar in your ListBox, use the ScrollBar.VerticalScrollBarVisibility attached property.

<ListBox 
    ItemsSource="{Binding}" 
    ScrollViewer.VerticalScrollBarVisibility="Visible">
</ListBox>

Setting this value to Auto will popup the scrollbar on an as needed basis.

I found that it would work to reset the month to January for both dates (the provided date and the present):

Here is something to try, using interface and destructuring with default values. Please note that "lastName" is optional.

interface IName {
  firstName: string
  lastName?: string
}

function sayName(params: IName) {
  const { firstName, lastName = "Smith" } = params
  const fullName = `${firstName} ${lastName}`

  console.log("FullName-> ", fullName)
}

sayName({ firstName: "Bob" })

As library requires minSdkVersion 17 then you can change the same in build.gradle(Module:Application) file:

defaultConfig {
        minSdkVersion 17 
        targetSdkVersion 25
}

and after that building the project should not throw any build error.

This can be done easily by first using tr to replace the newlines with some other character:

tr '\n' '\a' | grep -o 'abc.*def' | tr '\a' '\n'

Here, I am using the alarm character, \a (ASCII 7) in place of a newline. This is almost never found in your text, and grep can match it with a ., or match it specifically with \a.

You can use REINDEX to do that.

Reindex does not attempt to set up the destination index. It does not copy the settings of the source index. You should set up the destination index prior to running a _reindex action, including setting up mappings, shard counts, replicas, etc.

1. First copy the index to a new name

POST /_reindex
{
  "source": {
    "index": "twitter"
  },
  "dest": {
    "index": "new_twitter"
  }
}

2. Now delete the Index

DELETE /twitter

It's the new feature in C# 6 called Interpolated Strings.

The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.

For more details about this, please take a look at MSDN.

Now, think a little bit more about it. Why this feature is great?

For example, you have class Point:

public class Point
{
    public int X { get; set; }

    public int Y { get; set; }
}

Create 2 instances:

var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };

Now, you want to output it to the screen. The 2 ways that you usually use:

Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");

As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:

Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));

This creates a new problem:

1. You have to maintain the number of arguments and index yourself. If the number of arguments and index are not the same, it will generate a runtime error.

For those reasons, we should use new feature:

Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");

The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

For the full post, please read this blog.

Another possibility is not having emitDecoratorMetadata set to true in tsconfig.json

{
  "compilerOptions": {

     ...

    "emitDecoratorMetadata": true,

     ...

    }

}

An important difference is that some UARTs (16550 notably) will stop receiving characters immediately if their host instructs them to set DSR to be inactive. In contrast, characters will still be received if CTS is inactive. I believe that the intention here is that DSR indicates that the device is no longer listening and so sending any further characters is pointless, while CTS indicates that a buffer is getting full; the latter allows for a certain amount of 'skid' where the flow control line changed state between the DTE sampling it and the next character being transmitted. In (relatively) later devices that support a hardware FIFO it's possible that a number of characters could be transmitted after the DCE has set CTS to be inactive.

If all you need is a subject line (as in an alert message) simply do:

mailx -s "This is all she wrote" < /dev/null "myself@myaddress"

var $th = $td.closest('tbody').prev('thead').find('> tr > th:eq(' + $td.index() + ')');

Or a little bit simplified

var $th = $td.closest('table').find('th').eq($td.index());

Assuming that "a" and "b" are bean properties

rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"

You may look at JSF EL operators

For Java 8 this is one right way to do it:

Files.walk(new File("D:/temp").toPath())
                .map(f -> f.toFile())
                .filter(f -> f.isFile())
                .mapToLong(f -> f.length()).sum()

It is important to filter out all directories, because the length method isn't guaranteed to be 0 for directories.

At least this code delivers the same size information like Windows Explorer itself does.

What about that?

HTML

<div class="chart" id="graph" data-percent="88"></div>

var el = document.getElementById('graph'); // get canvas

var options = {
    percent:  el.getAttribute('data-percent') || 25,
    size: el.getAttribute('data-size') || 220,
    lineWidth: el.getAttribute('data-line') || 15,
    rotate: el.getAttribute('data-rotate') || 0
}

var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';

if (typeof(G_vmlCanvasManager) !== 'undefined') {
    G_vmlCanvasManager.initElement(canvas);
}

var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;

el.appendChild(span);
el.appendChild(canvas);

ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg

//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;

var drawCircle = function(color, lineWidth, percent) {
        percent = Math.min(Math.max(0, percent || 1), 1);
        ctx.beginPath();
        ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
        ctx.strokeStyle = color;
        ctx.lineCap = 'round'; // butt, round or square
        ctx.lineWidth = lineWidth
        ctx.stroke();
};

drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle('#555555', options.lineWidth, options.percent / 100);

    margin:80px;

Basic code was taken from Simple PIE Chart http://rendro.github.io/easy-pie-chart/

What does it mean?

It means that you should not try to use the same iterator in two threads. If you have two threads that need to iterate over the keys, values or entries, then they each should create and use their own iterators.

What happens if I try to iterate the map with two threads at the same time?

It is not entirely clear what would happen if you broke this rule. You could just get confusing behavior, in the same way that you do if (for example) two threads try to read from standard input without synchronizing. You could also get non-thread-safe behavior.

But if the two threads used different iterators, you should be fine.

What happens if I put or remove a value from the map while iterating it?

That's a separate issue, but the javadoc section that you quoted adequately answers it. Basically, the iterators are thread-safe, but it is not defined whether you will see the effects of any concurrent insertions, updates or deletions reflected in the sequence of objects returned by the iterator. In practice, it probably depends on where in the map the updates occur.

Many good answers here, but I use a simple one using Exists, as below:

foreach (var setting in FullList)
{
    if(cleanList.Exists(x => x.ProcedureName == setting.ProcedureName)) 
       setting.IsActive = true; // do you business logic here 
    else
       setting.IsActive = false;
    updateList.Add(setting);
}

You can use cat if installed, with the > caracter. Here is the manipulation :

cat > file_to_edit
#1 Write or Paste you text
#2 don't forget to leave a blank line at the end of file
#3 Ctrl + C to apply configuration

Now you can see the result with the command

cat file

You can do the access control at the Web server level using HTTP Basic authentication and htpasswd. There are a number of problems with this:

1. It's not very secure (username and password are trivially encoded on the wire)
2. It's difficult to maintain (you have to log into the server to add or remove users)
3. You have no control over the login dialog box presented by the browser
4. There is no way of logging out, short of restarting the browser.

Unless you're building a site for internal use with few users, I wouldn't really recommend it.

To install the GPL version of PyQt5, run (see PyQt5 Project):

pip3 install pyqt5

This will install the Python wheel for your platform and your version of Python (assuming both are supported).

(The wheel will be automatically downloaded from the Python Package Index.)

The PyQt5 wheel includes the necessary parts of the LGPL version of Qt. There is no need to install Qt yourself.

(The required sip is packaged as a separate wheel and will be downloaded and installed automatically.)

Note:

If you get an error message saying something as

No downloads could be found that satisfy the requirement 

then you are probably using an unsupported version of Python.

    onPressed: () { },
  );

  // set up the AlertDialog
  AlertDialog alert = AlertDialog(
    title: Text("My title"),
    content: Text("This is my message."),
    actions: [
      okButton,
    ],
  );

  // show the dialog
  showDialog(
    context: context,
    builder: (BuildContext context) {
      return alert;
    },
  );
}

Two Buttons

showAlertDialog(BuildContext context) {

  // set up the buttons
  Widget cancelButton = FlatButton(
    child: Text("Cancel"),
    onPressed:  () {},
  );
  Widget continueButton = FlatButton(
    child: Text("Continue"),
    onPressed:  () {},
  );

  // set up the AlertDialog
  AlertDialog alert = AlertDialog(
    title: Text("AlertDialog"),
    content: Text("Would you like to continue learning how to use Flutter alerts?"),
    actions: [
      cancelButton,
      continueButton,
    ],
  );

  // show the dialog
  showDialog(
    context: context,
    builder: (BuildContext context) {
      return alert;
    },
  );
}

Three Buttons

showAlertDialog(BuildContext context) {

  // set up the buttons
  Widget remindButton = FlatButton(
    child: Text("Remind me later"),
    onPressed:  () {},
  );
  Widget cancelButton = FlatButton(
    child: Text("Cancel"),
    onPressed:  () {},
  );
  Widget launchButton = FlatButton(
    child: Text("Launch missile"),
    onPressed:  () {},
  );

  // set up the AlertDialog
  AlertDialog alert = AlertDialog(
    title: Text("Notice"),
    content: Text("Launching this missile will destroy the entire universe. Is this what you intended to do?"),
    actions: [
      remindButton,
      cancelButton,
      launchButton,
    ],
  );

  // show the dialog
  showDialog(
    context: context,
    builder: (BuildContext context) {
      return alert;
    },
  );
}

Handling button presses

The onPressed callback for the buttons in the examples above were empty, but you could add something like this:

Widget launchButton = FlatButton(
  child: Text("Launch missile"),
  onPressed:  () {
    Navigator.of(context).pop(); // dismiss dialog
    launchMissile();
  },
);

If you make the callback null, then the button will be disabled.

onPressed: null,

Supplemental code

Here is the code for main.dart in case you weren't getting the functions above to run.

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter'),
        ),
        body: MyLayout()),
    );
  }
}

class MyLayout extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(8.0),
      child: RaisedButton(
        child: Text('Show alert'),
        onPressed: () {
          showAlertDialog(context);
        },
      ),
    );
  }
}

// replace this function with the examples above
showAlertDialog(BuildContext context) { ... }

What about using the change event of Jquery?

$(function() {
    $('input:radio[name="myRadios"]').change(function() {
        if ($(this).val() == '1') {
            alert("You selected the first option and deselected the second one");
        } else {
            alert("You selected the second option and deselected the first one");
        }
    });
});

Your code looks correct. Try logging in through your browser and if you are able to access your account come back and try your code again. Just make sure that you have typed your username and password correct

To me a simple

sudo apt-get update

solved the issue. It was a clock issue and with this command it resets to the current date/time and everything worked

Here is yet another way which fits in one line but is not particularly elegant:

dt = datetime.datetime.fromordinal(datetime.date.today().toordinal())

Adding this for diversity and clean approach.

This code uses functional style approach. I have used onresize instead of addEventListener as mentioned in other answers.

import { useState, useEffect } from "react";

export default function App() {
  const [size, setSize] = useState({
    x: window.innerWidth,
    y: window.innerHeight
  });
  const updateSize = () =>
    setSize({
      x: window.innerWidth,
      y: window.innerHeight
    });
  useEffect(() => (window.onresize = updateSize), []);
  return (
    <>
      <p>width is : {size.x}</p>
      <p>height is : {size.y}</p>
    </>
  );
}

With your current requirement this would work :

    def start_html():
        return '<html>'

    def end_html():
        return '</html>'

    def print_html(text):
        text = str(text)
        text = text.replace('\n', '<br>')
        return '<p>' + str(text) + '</p>'
if __name__ == '__main__':
        webpage_data =  start_html()
        webpage_data += print_html("Hi Welcome to Python test page\n")
        webpage_data += fd.write(print_html("Now it will show a calculation"))
        webpage_data += print_html("30+2=")
        webpage_data += print_html(30+2)
        webpage_data += end_html()
        with open('index.html', 'w') as fd: fd.write(webpage_data)

open the index.html and you will see what you want

If you are trying to

1. Use multiple delimiters
2. Filter any empty strings
3. Trim leading/trailing spaces

following should work:

string str = "Tom Cruise, Scott, ,Bob | at";
IEnumerable<string> names = str
                            .Split(new char[]{',', '|'})
                            .Where(x=>x!=null && x.Trim().Length > 0)
                            .Select(x=>x.Trim());

Output

• Tom
• Cruise
• Scott
• Bob
• at

Now you can obviously reverse the order as others suggested.

Here is an alternative way to get an object's property value:

write-host $(get-something).SomeProp

Try this

new DropdownButton<String>(
  items: <String>['A', 'B', 'C', 'D'].map((String value) {
    return new DropdownMenuItem<String>(
      value: value,
      child: new Text(value),
    );
  }).toList(),
  onChanged: (_) {},
)

Just in case, if someone is looking for a similar problem...

Most solutions given here are one line and are quite readable and simple. Just wanted to add one more that does not need the use of lambda(I am assuming that you are trying to use lambda just for the sake of making it a one line code). Instead, you can use a simple list comprehension.

[print(i) for i in x]

BTW, the return values will be a list on None s.

You can simply handle the NO_DATA_FOUND exception by setting your variable to NULL. This way, only one query is required.

    v_column my_table.column%TYPE;

BEGIN

    BEGIN
      select column into v_column from my_table where ...;
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        v_column := NULL;
    END;

    ... use v_column here
END;

In C++17, we can use variants.

To use std::variant, you need to include the header:

#include <variant>

After that, you may add std::variant in your code like this:

using Type = std::variant<Animal, Person>;

template <class T>
void foo(Type type) {
    if (std::is_same_v<type, Animal>) {
        // Do stuff...
    } else {
        // Do stuff...
    }
}

The way you are using await/async is poor at best, and it makes it hard to follow. You are mixing await with Task'1.Result, which is just confusing. However, it looks like you are looking at a final task result, rather than the contents.

I've rewritten your function and function call, which should fix your issue:

async Task<string> GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = await httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters));
    var contents = await response.Content.ReadAsStringAsync();

    return contents;
}

And your final function call:

Task<string> result = GetResponseString(text);
var finalResult = result.Result;

Or even better:

var finalResult = await GetResponseString(text);

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

I was just struggling with same situation. Following solved the issue:

If you have directory structure like this:

folders:
    - map: /Users/me/code/exampleproject
      to: /home/vagrant/code/exampleproject

Just create 'public' folder within exampleproject on your host machine.

Many thanks to Dorian and Phrogz for reminding me about the array (and hash) method #replace, which can "replace the contents of an array or hash."

The notion that a CONSTANT's value can be changed, but with an annoying warning, is one of Ruby's few conceptual mis-steps -- these should either be fully immutable, or dump the constant idea altogether. From a coder's perspective, a constant is declarative and intentional, a signal to other that "this value is truly unchangeable once declared/assigned."

But sometimes an "obvious declaration" actually forecloses other, future useful opportunities. For example...

There are legitimate use cases where a "constant's" value might really need to be changed: for example, re-loading ARGV from a REPL-like prompt-loop, then rerunning ARGV thru more (subsequent) OptionParser.parse! calls -- voila! Gives "command line args" a whole new dynamic utility.

The practical problem is either with the presumptive assumption that "ARGV must be a constant", or in optparse's own initialize method, which hard-codes the assignment of ARGV to the instance var @default_argv for subsequent processing -- that array (ARGV) really should be a parameter, encouraging re-parse and re-use, where appropriate. Proper parameterization, with an appropriate default (say, ARGV) would avoid the need to ever change the "constant" ARGV. Just some 2¢-worth of thoughts...

You can use int() function to convert float64 type data to an int. Similarly you can use float64()

Example:

func check(n int) bool { 
    // count the number of digits 
    var l int = countDigit(n)
    var dup int = n 
    var sum int = 0 

    // calculates the sum of digits 
    // raised to power 
    for dup > 0 { 
        **sum += int(math.Pow(float64(dup % 10), float64(l)))** 
        dup /= 10 
    } 

    return n == sum
} 

In addition to kieran's answer, apparently, modern browsers have an Object.keys function. In this case, you could do this:

Object.keys(jsonArray).length;

If you try to console log query object directly you will get error TypeError: Cannot convert object to primitive value

So I would suggest use JSON.stringify

const http = require('http');
const url = require('url');

const server = http.createServer((req, res) => {
    const parsedUrl = url.parse(req.url, true);

    const path = parsedUrl.pathname, query = parsedUrl.query;
    const method = req.method;

    res.end("hello world\n");

    console.log(`Request received on: ${path} + method: ${method} + query: 
    ${JSON.stringify(query)}`);
    console.log('query: ', query);
  });


  server.listen(3000, () => console.log("Server running at port 3000"));

So doing curl http://localhost:3000/foo\?fizz\=buzz will return Request received on: /foo + method: GET + query: {"fizz":"buzz"}

When to use each

@staticmethod function is nothing more than a function defined inside a class. It is callable without instantiating the class first. It’s definition is immutable via inheritance.

• Python does not have to instantiate a bound-method for object.
• It eases the readability of the code: seeing @staticmethod, we know that the method does not depend on the state of object itself;

@classmethod function also callable without instantiating the class, but its definition follows Sub class, not Parent class, via inheritance, can be overridden by subclass. That’s because the first argument for @classmethod function must always be cls (class).

• Factory methods, that are used to create an instance for a class using for example some sort of pre-processing.
• Static methods calling static methods: if you split a static methods in several static methods, you shouldn't hard-code the class name but use class methods

This grants root access with the same password from any machine in *.example.com:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%.example.com' 
    IDENTIFIED BY 'some_characters' 
    WITH GRANT OPTION;
FLUSH PRIVILEGES;

If name resolution is not going to work, you may also grant access by IP or subnet:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.%'
    IDENTIFIED BY 'some_characters'  
    WITH GRANT OPTION;

Use

This should work ^^

The font tag has been deprecated for some time now.

That being said, the reason why both of your tables display with the same font size is that the 'size' attribute only accepts values ranging from 1 - 7. The smallest size is 1. The largest size is 7. The default size is 3. Any values larger than 7 will just display the same as if you had used 7, because 7 is the maximum value allowed.

And as @Alex H said, you should be using CSS for this.

If your button is loading from an AJAX call, you should use

$(document).on("click", ".delegate_update_success", function(){
    location.reload(true);
});

instead of

$( ".delegate_update_success" ).click(function() {
    location.reload();
});

Also note the true parameter for the location.reload function.

The onunload event won't fire if the onload event did not fire. Unfortunately the onload event waits for all binary content (e.g. images) to load, and inline scripts run before the onload event fires. DOMContentLoaded fires when the page is visible, before onload does. And it is now standard in HTML 5, and you can test for browser support but note this requires the <!DOCTYPE html> (at least in Chrome). However, I can not find a corresponding event for unloading the DOM. And such a hypothetical event might not work because some browsers may keep the DOM around to perform the "restore tab" feature.

The only potential solution I found so far is the Page Visibility API, which appears to require the <!DOCTYPE html>.

Friend. Use this way, There will be no "Undefined variable message" and it will work fine.

<?php
    if(isset($_POST['SubmitButton'])){
        $price = $_POST["price"];
        $qty = $_POST["qty"];
        $message = $price*$qty;
    }

        ?>

    <!DOCTYPE html>
    <html>
    <head>
        <title></title>
    </head>
    <body>
        <form action="#" method="post">
            <input type="number" name="price"> <br>
            <input type="number" name="qty"><br>
            <input type="submit" name="SubmitButton">
        </form>
        <?php echo "The Answer is" .$message; ?>

    </body>
    </html>

Unfortunately for MSForms list box looping through the list items and checking their Selected property is the only way. However, here is an alternative. I am storing/removing the selected item in a variable, you can do this in some remote cell and keep track of it :)

Dim StrSelection As String

Private Sub ListBox1_Change()
    If ListBox1.Selected(ListBox1.ListIndex) Then
        If StrSelection = "" Then
            StrSelection = ListBox1.List(ListBox1.ListIndex)
        Else
            StrSelection = StrSelection & "," & ListBox1.List(ListBox1.ListIndex)
        End If
    Else
        StrSelection = Replace(StrSelection, "," & ListBox1.List(ListBox1.ListIndex), "")
    End If
End Sub

Section 2 of RFC 2368 says that the body field is supposed to be in text/plain format, so you can't do HTML.

However even if you use plain text it's possible that some modern mail clients would render a URL as a clickable link anyway, though.

In Ruby, a block is basically a chunk of code that can be passed to and executed by any method. Blocks are always used with methods, which usually feed data to them (as arguments).

Blocks are widely used in Ruby gems (including Rails) and in well-written Ruby code. They are not objects, hence cannot be assigned to variables.

Basic Syntax

A block is a piece of code enclosed by { } or do..end. By convention, the curly brace syntax should be used for single-line blocks and the do..end syntax should be used for multi-line blocks.

{ # This is a single line block }

do
  # This is a multi-line block
end 

Any method can receive a block as an implicit argument. A block is executed by the yield statement within a method. The basic syntax is:

def meditate
  print "Today we will practice zazen"
  yield # This indicates the method is expecting a block
end 

# We are passing a block as an argument to the meditate method
meditate { print " for 40 minutes." }

Output:
Today we will practice zazen for 40 minutes.

When the yield statement is reached, the meditate method yields control to the block, the code within the block is executed and control is returned to the method, which resumes execution immediately following the yield statement.

When a method contains a yield statement, it is expecting to receive a block at calling time. If a block is not provided, an exception will be thrown once the yield statement is reached. We can make the block optional and avoid an exception from being raised:

def meditate
  puts "Today we will practice zazen."
  yield if block_given? 
end meditate

Output:
Today we will practice zazen. 

It is not possible to pass multiple blocks to a method. Each method can receive only one block.

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

You can also use pygooglechart, which uses the Google Chart API. This isn't something you'd always want to use, but if you want a small number of good, simple, charts, and are always online, and especially if you're displaying in a browser anyway, it's a good choice.

You can't set the field having data-type "text". Only because of that thing you are getting this error. Try to change the data-type with int
