It seems, it is an issue in the old versions, I installed the last version :

Docker version 19.03.5, build 633a0ea

and it worked for me without any configuration.

it is always good to restrict the DOM search. so better to use a parent also, so that the entire DOM won't be traversed.

IT IS VERY FAST

<div id="radioBtnDiv">
  <input name="myButton" type="radio" class="radioClass" value="manual" checked="checked"/>
 <input name="myButton" type="radio" class="radioClass" value="auto" checked="checked"/>
</div>



 $("input[name='myButton']",$('#radioBtnDiv')).change(
    function(e)
    {
        // your stuffs go here
    });

Using the stat.* bit masks does seem to me the most portable and explicit way of doing this. But on the other hand, I often forget how best to handle that. So, here's an example of masking out the 'group' and 'other' permissions and leaving 'owner' permissions untouched. Using bitmasks and subtraction is a useful pattern.

import os
import stat
def chmodme(pn):
    """Removes 'group' and 'other' perms. Doesn't touch 'owner' perms."""
    mode = os.stat(pn).st_mode
    mode -= (mode & (stat.S_IRWXG | stat.S_IRWXO))
    os.chmod(pn, mode)

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

I ran into a problem where the typical position: fixed and bottom: 0 didn't work. Discovered a neat functionality with position: sticky. Note it's "relatively" new so it won't with IE/Edge 15 and earlier.

Here's an example for w3schools.

<!DOCTYPE html>
<html>
<head>
<style>
div.sticky {
  position: sticky;
  bottom: 0;
  background-color: yellow;
  padding: 30px;
  font-size: 20px;
}
</style>
</head>

I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()

My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:

{{'0' if linked_contacts == None else linked_contacts|length}}

/var/www/html is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf file (usually located in /etc/apache/conf) and changing the DocumentRoot attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)

Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

It means "no value". You use void to indicate that a function doesn't return a value or that it has no parameters or both.It's much consistent with typical uses of word void in English.

Void should not be confused with null. Null means for the variable whose address is on stack, the value on the heap for that address is empty.

You'd have to use WebSockets (or some similar protocol module e.g. as supported by the Flash plugin) because a normal browser application simply can't open a pure TCP socket.

The Socket.IO module available for node.js can help a lot, but note that it is not a pure WebSocket module in its own right.

It's actually a more generic communications module that can run on top of various other network protocols, including WebSockets, and Flash sockets.

Hence if you want to use Socket.IO on the server end you must also use their client code and objects. You can't easily make raw WebSocket connections to a socket.io server as you'd have to emulate their message protocol.

join is not a jQuery function .Its a javascript function.

The join() method joins the elements of an array into a string, and returns the string.The elements will be separated by a specified separator. The default separator is comma (,).

Steve Smith did two great blog posts which demonstrate how to use his CachedRepository pattern in ASP.NET MVC. It uses the repository pattern effectively and allows you to get caching without having to change your existing code.

http://ardalis.com/Introducing-the-CachedRepository-Pattern

http://ardalis.com/building-a-cachedrepository-via-strategy-pattern

In these two posts he shows you how to set up this pattern and also explains why it is useful. By using this pattern you get caching without your existing code seeing any of the caching logic. Essentially you use the cached repository as if it were any other repository.

Use following interface to communicate between activity and fragment

public interface BundleListener {
    void update(Bundle bundle);
    Bundle getBundle();
}

Or use following this generic listener for two way communication using interface

 /**
 * Created by Qamar4P on 10/11/2017.
 */
public interface GenericConnector<T,E> {
    T getData();
    void updateData(E data);
    void connect(GenericConnector<T,E> connector);
}

fragment show method

public static void show(AppCompatActivity activity) {
        CustomValueDialogFragment dialog = new CustomValueDialogFragment();
        dialog.connector = (GenericConnector) activity;
        dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
    }

you can cast your context to GenericConnector in onAttach(Context) too

in your activity

CustomValueDialogFragment.show(this);

in your fragment

...
@Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        connector.connect(new GenericConnector() {
            @Override
            public Object getData() {
                return null;
            }

            @Override
            public void updateData(Object data) {

            }

            @Override
            public void connect(GenericConnector connector) {

            }
        });
    }
...
    public static void show(AppCompatActivity activity, GenericConnector connector) {
            CustomValueDialogFragment dialog = new CustomValueDialogFragment();
            dialog.connector = connector;
            dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
        }

Note: Never use it like "".toString().toString().toString(); way.

for ST3

$language = "language u wish"

if exists,

go to ~/.config/sublime-text-3/Packages/User/$language.sublime-settings

else

create ~/.config/sublime-text-3/Packages/User/$language.sublime-settings

and set

{ "extensions": [ "yourextension" ] }

This way allows you to enable syntax for composite extensions (e.g. sql.mustache, js.php, etc ... )

try this worked for me :

checkValue(event: any) {
    this.siteSelected.majeur = event;
}

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

Why use GROUP BY at all?

SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players
ORDER BY player_salary DESC

you can do it only in one line as below:

$cnt = mysql_num_rows(mysql_query("SELECT COUNT(1) FROM TABLE"));
echo $cnt;

Page reload can be done using javascript code. Use either a HTML button and implement it like...

<input type="button" value="Reload Page" onClick="document.location.reload(true)">

In .Net Core 3+ and .Net 5+:

string escapedJsonString = JsonEncodedText.Encode(jsonString);

There is a new library called ipyvolume that may do what you want, the documentation shows live demos. The current version doesn't do meshes and lines, but master from the git repo does (as will version 0.4). (Disclaimer: I'm the author)

The problem with the accepted answer is that it cannot signal failure. There's strtol (STRing TO Long) which can. It's part of a larger family: wcstol (Wide Character String TO Long, e.g. Unicode), strtoull (TO Unsigned Long Long, 64bits+), wcstoull, strtof (TO Float) and wcstof.

I case your observations are classes from Real numbers and you expect that the mode to be 2.5 when your observations are 2, 2, 3, and 3 then you could estimate the mode with mode = l1 + i * (f1-f0) / (2f1 - f0 - f2) where l1..lower limit of most frequent class, f1..frequency of most frequent class, f0..frequency of classes before most frequent class, f2..frequency of classes after most frequent class and i..Class interval as given e.g. in 1, 2, 3:

#Small Example
x <- c(2,2,3,3) #Observations
i <- 1          #Class interval

z <- hist(x, breaks = seq(min(x)-1.5*i, max(x)+1.5*i, i), plot=F) #Calculate frequency of classes
mf <- which.max(z$counts)   #index of most frequent class
zc <- z$counts
z$breaks[mf] + i * (zc[mf] - zc[mf-1]) / (2*zc[mf] - zc[mf-1] - zc[mf+1])  #gives you the mode of 2.5


#Larger Example
set.seed(0)
i <- 5          #Class interval
x <- round(rnorm(100,mean=100,sd=10)/i)*i #Observations

z <- hist(x, breaks = seq(min(x)-1.5*i, max(x)+1.5*i, i), plot=F)
mf <- which.max(z$counts)
zc <- z$counts
z$breaks[mf] + i * (zc[mf] - zc[mf-1]) / (2*zc[mf] - zc[mf-1] - zc[mf+1])  #gives you the mode of 99.5

In case you want the most frequent level and you have more than one most frequent level you can get all of them e.g. with:

x <- c(2,2,3,5,5)
names(which(max(table(x))==table(x)))
#"2" "5"

Here a code that works with windows office 2010. This script will ask you for input filtered range of cells and then the paste range.

Please, both ranges should have the same number of cells.

Sub Copy_Filtered_Cells()

Dim from As Variant
Dim too As Variant
Dim thing As Variant
Dim cell As Range

'Selection.SpecialCells(xlCellTypeVisible).Select

    'Set from = Selection.SpecialCells(xlCellTypeVisible)
    Set temp = Application.InputBox("Copy Range :", Type:=8)
    Set from = temp.SpecialCells(xlCellTypeVisible)
    Set too = Application.InputBox("Select Paste range selected cells ( Visible cells only)", Type:=8)



    For Each cell In from
        cell.Copy
        For Each thing In too
            If thing.EntireRow.RowHeight > 0 Then
                thing.PasteSpecial
                Set too = thing.Offset(1).Resize(too.Rows.Count)
                Exit For
            End If
        Next
    Next


End Sub

Enjoy!

Also you can use this

private static final String ALLOWED_URI_CHARS = "@#&=*+-_.,:!?()/~'%";
String urlEncoded = Uri.encode(path, ALLOWED_URI_CHARS);

it's the most simple method

Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:

Public Sub SubA()
  On Error Goto ProcError

  Connection.Open
  Open File for Writing
  SomePreciousResource.GrabIt

ProcExit:  
  Connection.Close
  Connection = Nothing
  Close File
  SomePreciousResource.Release

  Exit Sub

ProcError:  
  MsgBox Err.Description  
  Resume ProcExit
End Sub

Here's a simplified version with extended explanation for beginners like me who are trying to learn how to put more than one command in one line.

If you were to write out the problem in steps, it would look like this:

// For every file in this directory
// Check the filetype
// If it's an ASCII file, then print out the filename

To achieve this, we can use three UNIX commands: find, file, and grep.

find will check every file in the directory.

file will give us the filetype. In our case, we're looking for a return of 'ASCII text'

grep will look for the keyword 'ASCII' in the output from file

So how can we string these together in a single line? There are multiple ways to do it, but I find that doing it in order of our pseudo-code makes the most sense (especially to a beginner like me).

find ./ -exec file {} ";" | grep 'ASCII'

Looks complicated, but not bad when we break it down:

find ./ = look through every file in this directory. The find command prints out the filename of any file that matches the 'expression', or whatever comes after the path, which in our case is the current directory or ./

The most important thing to understand is that everything after that first bit is going to be evaluated as either True or False. If True, the file name will get printed out. If not, then the command moves on.

-exec = this flag is an option within the find command that allows us to use the result of some other command as the search expression. It's like calling a function within a function.

file {} = the command being called inside of find. The file command returns a string that tells you the filetype of a file. Regularly, it would look like this: file mytextfile.txt. In our case, we want it to use whatever file is being looked at by the find command, so we put in the curly braces {} to act as an empty variable, or parameter. In other words, we're just asking for the system to output a string for every file in the directory.

";" = this is required by find and is the punctuation mark at the end of our -exec command. See the manual for 'find' for more explanation if you need it by running man find.

| grep 'ASCII' = | is a pipe. Pipe take the output of whatever is on the left and uses it as input to whatever is on the right. It takes the output of the find command (a string that is the filetype of a single file) and tests it to see if it contains the string 'ASCII'. If it does, it returns true.

NOW, the expression to the right of find ./ will return true when the grep command returns true. Voila.

I was facing the same issue. I tried both $http_my_custom_header and $sent_http_my_custom_header but it did not work for me.

Although solved this issue by using $upstream_http_my_custom_header.

I'm sitting at a computer with none of the relevant bits of software, but from memory that code looks wrong. You're executing the command but discarding the RecordSet that objMyCommand.Execute returns.

I'd do:

Set objMyRecordset = objMyCommand.Execute

...and then lose the "open recordset" part.

I solved it as follows:

1) try to locate ctr1.o and ctri.o files by using find -name ctr1.o

I got the following in my computer: $/usr/lib/i386-linux/gnu

2) Add that path to PATH (also LIBRARY_PATH) environment variable (in order to see which is the name: type env command in the Terminal):

$PATH=/usr/lib/i386-linux/gnu:$PATH
$export PATH

You can attach a SLOT to the

void aboutToQuit();

signal of your QApplication. This signal should be raised just before app closes.

Maybe i dont understand , why cant you just get the element.text and then convert it before using it ? for instance (dont know why you would do this but...) find all label elements of the web page and iterate between them until you find one called MyText

        avail = []
        avail = driver.find_elements_by_class_name("label");
        for i in avail:
                if  i.text == "MyText":

Convert the string from i and do whatever you wanted to do ... maybe im missing something in the original message ? or was this what you were looking for ?

Here is what backup in this sense really means:

Android's backup service allows you to copy your persistent application data to remote "cloud" storage, in order to provide a restore point for the application data and settings. If a user performs a factory reset or converts to a new Android-powered device, the system automatically restores your backup data when the application is re-installed. This way, your users don't need to reproduce their previous data or application settings.

~Taken from http://developer.android.com/guide/topics/data/backup.html

You can register for this backup service as a developer here: https://developer.android.com/google/backup/signup.html

The type of data that can be backed up are files, databases, sharedPreferences, cache, and lib. These are generally stored in your device's /data/data/[com.myapp] directory, which is read-protected and cannot be accessed unless you have root privileges.

UPDATE: You can see this flag listed on BackupManager's api doc: BackupManager

According to others said, you cannot instantiate from abstract class. but it exist 2 way to use it. 1. make another non-abstact class that extends from abstract class. So you can instantiate from new class and use the attributes and methods in abstract class.

    public class MyCustomClass extends YourAbstractClass {

/// attributes, methods ,...
}

2. work with interfaces.

You can always use the DATALENGTH Function to determine if you have extra white space characters in text fields. This won't make the text visible but will show you where there are extra white space characters.

    SELECT DATALENGTH('MyTextData ') AS BinaryLength, LEN('MyTextData ') AS TextLength

This will produce 11 for BinaryLength and 10 for TextLength.

In a table your SQL would like this:

    SELECT * 
    FROM tblA
    WHERE DATALENGTH(MyTextField) > LEN(MyTextField)

This function is usable in all versions of SQL Server beginning with 2005.

java -jar server-0.0.1-SNAPSHOT.jar --spring.config.location=application-prod.properties

Well you understood it partially. You have to tailor the beans according to your need and inform Spring container to manage it when required, by using a methodology populalrly known as IoC (Inversion of Control) coined by Martin Fowler, also known as Dependency Injection (DI).

You wire the beans in a way, so that you do not have to take care of the instantiating or evaluate any dependency on the bean. This is popularly known as Hollywood Principle.

Google is the best tool to explore more on this in addition to the links you would get flooded with here in this question. :)

Shuffling the numbers from 1 to 100 is the right basic strategy, but if you need only 8 shuffled numbers, there's no need to shuffle all 100 numbers.

I don't know Javascript very well, but I believe it's easy to create an array of 100 nulls quickly. Then, for 8 rounds, you swap the n'th element of the array (n starting at 0) with a randomly selected element from n+1 through 99. Of course, any elements not populated yet mean that the element would really have been the original index plus 1, so that's trivial to factor in. When you're done with the 8 rounds, the first 8 elements of your array will have your 8 shuffled numbers.

Try using System.getProperty("line.separator") to get a new line.

For Kotlin on fragment just do this

activity?.runOnUiThread(Runnable {
        //on main thread
    })

Multiple questions require input for several integers on single line. The best way is to input the whole string of numbers one one line and then split them to integers. Here is a Python 3 version:

a = []
p = input()
p = p.split()      
for i in p:
    a.append(int(i))

Also a list comprehension can be used

p = input().split("whatever the seperator is")

And to convert all the inputs from string to int we do the following

x = [int(i) for i in p]
print(x, end=' ')

shall print the list elements in a straight line.

With Guava 15 you can also simply use:

Set s = Sets.newConcurrentHashSet();

One option is to use an attribute on the image, and modify that using jQuery. Then take that value in CSS:

HTML (note I'm assuming .cloumn is a div but it could be anything):

<div class="column" bf-width=100 >
    <img src="..." />
</div>

jQuery:

// General use:
$('.column').attr('bf-width', 100);
// With your image, along the lines of:
$('.column').attr('bf-width', $('img').width());

And then in order to use that value in CSS:

.column:before {
    content: attr(data-content) 'px';
    /* ... */
}

This will grab the attribute value from .column, and apply it on the before.

Sources: CSS attr (note the examples with before), jQuery attr.

try componentDidMount() lifecycle when fetching data

You can use GET variables in the action parameter of your form element. Example:

<form method="post" action="script.php?foo=bar">
    <input name="quu" ... />
    ...
</form>

This will give you foo as a GET variable and quu as a POST variable.

Hope this code helps you out :)

In my case, none of the code above with bundle-operate works; Here is my decision (I don't know if it is proper code or not, but it works in my case):

public class DialogMessageType extends DialogFragment {
    private static String bodyText;

    public static DialogMessageType addSomeString(String temp){
        DialogMessageType f = new DialogMessageType();
        bodyText = temp;
        return f;
    };

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final String[] choiseArray = {"sms", "email"};
        String title = "Send text via:";
        final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle(title).setItems(choiseArray, itemClickListener);
        builder.setCancelable(true);
        return builder.create();
    }

    DialogInterface.OnClickListener itemClickListener = new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch (which){
                case 0:
                    prepareToSendCoordsViaSMS(bodyText);
                    dialog.dismiss();
                    break;
                case 1:
                    prepareToSendCoordsViaEmail(bodyText);
                    dialog.dismiss();
                    break;
                default:
                    break;
            }
        }
    };
[...]
}

public class SendObjectActivity extends FragmentActivity {

DialogMessageType dialogMessageType = DialogMessageType.addSomeString(stringToSend);
dialogMessageType.show(getSupportFragmentManager(),"dialogMessageType");

[...]
}

Debugging build step failures is indeed very annoying.

The best solution I have found is to make sure that each step that does real work succeeds, and adding a check after those that fails. That way you get a committed layer that contains the outputs of the failed step that you can inspect.

nice one guys!

If you have a list and you want to know where within the list an element exists that matches a given criteria, you can use the FindIndex instance method. Such as

int index = list.FindIndex(f => f.Bar == 17);

Where f => f.Bar == 17 is a predicate with the matching criteria.

In your case you might write

int index = pricePublicList.FindIndex(item => item.Size == 200);
if (index >= 0) 
{
    // element exists, do what you need
}

Download Androidx86 from this This is an iso file, so you'd
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux instead of Other.

After creating the virtual machine set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot.

Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.

Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.

Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.

In VirtualBox screen, go to Devices>USB devices. Select your dongle.

Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.

Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.

Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .

For anybody interested in Titanium i must say that they don't have a very good documentation some classes, properties, methods are missing. But a lot is "documented" in their sample app the KitchenSink so it is not THAT bad.

You can solve the problem by checking if your date matches a REGEX pattern. If not, then NULL (or something else you prefer).

In my particular case it was necessary because I have >20 DATE columns saved as CHAR, so I don't know from which column the error is coming from.

Returning to your query:

1. Declare a REGEX pattern.
It is usually a very long string which will certainly pollute your code (you may want to reuse it as well).

define REGEX_DATE = "'your regex pattern goes here'"

Don't forget a single quote inside a double quote around your Regex :-)

A comprehensive thread about Regex date validation you'll find here.

2. Use it as the first CASE condition:

To use Regex validation in the SELECT statement, you cannot use REGEXP_LIKE (it's only valid in WHERE. It took me a long time to understand why my code was not working. So it's certainly worth a note.

Instead, use REGEXP_INSTR
For entries not found in the pattern (your case) use REGEXP_INSTR (variable, pattern) = 0 .

    DEFINE REGEX_DATE = "'your regex pattern goes here'"

    SELECT   c.contract_num,
         CASE
            WHEN REGEXP_INSTR(c.event_dt, &REGEX_DATE) = 0 THEN NULL
            WHEN   (  MAX (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                    - MIN (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                 / COUNT (c.event_occurrence) < 32
            THEN
              'Monthly'
            WHEN       (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                        - MIN (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                     / COUNT (c.event_occurrence) >= 32
                 AND   (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))

var b = document.getElementById("c").previousElementSibling;

You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:

lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)

Then you can get hold of the axes objects (an array of axes):

axes = lm.axes

After that you can tweak the axes properties

axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)

creates:

You have to use v-html directive for displaying html content inside a vue component

<div v-html="html content data property"></div>

sklearn.cross_validation is now changed to sklearn.model_selection

Just use

from sklearn.model_selection import train_test_split

I think that will work.

Coarse-grained granularity does not always mean bigger components, if you go by literally meaning of the word coarse, it means harsh, or not appropriate. e.g. In software projects management, if you breakdown a small system into few components, which are equal in size, but varies in complexities and features, this could lead to a coarse-grained granularity. In reverse, for a fine-grained breakdown, you would divide the components based on their cohesiveness of the functionalities each component is providing.

There is no "canonical" way to do the matrix in C++, STL does not provide classes like "matrix". However there are some 3rd party libraries that do. You are encouraged to use them or write your own implementation. You can try my implementation derived from some public implementation found on the internet.

simply you can use jquery plugin to get/set the content of the div.

var divContent = $('#'DIV1).html(); $('#'DIV2).html(divContent );

for this you need to include jquery library.

Add the following line in your Dockerfile then rebuild the docker image.

You need a loop over the lines of a file, you need to learn about string methods

with open(filename,'r') as f:
    for line in f.readlines():
        # python can do regexes, but this is for s fixed string only
        if "something" in line:
            idx1 = line.find('"')
            idx2 = line.find('"', idx1+1)
            field = line[idx1+1:idx2-1]
            print(field)

and you need a method to pass the filename to your python program and while you are at it, maybe also the string to search for...

For the future, try to ask more focused questions if you can,

I once had a json that had ids that needed to be incremented by one since they were 0-indexed and that was breaking Mysql auto-increment.

So for each object I wrote this code - might be helpful to someone:

public static void  incrementValue(JSONObject obj, List<String> keysToIncrementValue) {
        Set<String> keys = obj.keySet();
        for (String key : keys) {
            Object ob = obj.get(key);

            if (keysToIncrementValue.contains(key)) {
                obj.put(key, (Integer)obj.get(key) + 1);
            }

            if (ob instanceof JSONObject) {
                incrementValue((JSONObject) ob, keysToIncrementValue);
            }
            else if (ob instanceof JSONArray) {
                JSONArray arr = (JSONArray) ob;
                for (int i=0; i < arr.length(); i++) {
                    Object arrObj = arr.get(0);
                    if (arrObj instanceof JSONObject) {
                        incrementValue((JSONObject) arrObj, keysToIncrementValue);
                    }
                }
            }
        }
    }

usage:

JSONObject object = ....
incrementValue(object, Arrays.asList("id", "product_id", "category_id", "customer_id"));

this can be transformed to work for JSONArray as parent object too

There are several ways to do it This is the better way

res.download('/report-12345.pdf')

or in your case this might be

app.get('/download', function(req, res){
  const file = `${__dirname}/upload-folder/dramaticpenguin.MOV`;
  res.download(file); // Set disposition and send it.
});

yes you can by using static class. like this:

static class Global
{
    private static string _globalVar = "";

    public static string GlobalVar
    {
        get { return _globalVar; }
        set { _globalVar = value; }
    }
}

and for using any where you can write:

GlobalClass.GlobalVar = "any string value"

Have your server listen on 0.0.0.0 instead of localhost.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

NAs also appear if there are attributes with zero variance (with all elements equal); see for instance:

cor(cbind(a=runif(10),b=rep(1,10)))

which returns:

   a  b
a  1 NA
b NA  1
Warning message:
In cor(cbind(a = runif(10), b = rep(1, 10))) :
  the standard deviation is zero

.navigationLevel2 li { color: #aa0000 }

1. Close the project
2. Just delete the modules.xml in .idea folder.
3. Open the project again.

Combining the answers from @Ortomala Lokni and @rogerdpack, another alternative is to have the dependent service monitor when the first one has started / done the thing you're waiting for.

For example, here's how I am making the fail2ban service wait for Docker to open port 443 (so that fail2ban's iptables entries take priority over Docker's):

[Service]
ExecStartPre=/bin/bash -c '(while ! nc -z -v -w1 localhost 443 > /dev/null; do echo "Waiting for port 443 to open..."; sleep 2; done); sleep 2'

Simply replace nc -z -v -w1 localhost 443 with a command that fails (non-zero exit code) while the first service is starting and succeeds once it is up.

For the Cassandra case, the ideal would be a command that only returns 0 when the cluster is available.

As per the documentation: This allows you to switch from the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.

This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, sitecustomize.py, After this module has been evaluated, the setdefaultencoding() function is removed from the sys module.

The only way to actually use it is with a reload hack that brings the attribute back.

Also, the use of sys.setdefaultencoding() has always been discouraged, and it has become a no-op in py3k. The encoding of py3k is hard-wired to "utf-8" and changing it raises an error.

I suggest some pointers for reading:

• http://blog.ianbicking.org/illusive-setdefaultencoding.html

For Angular 7, I followed these steps to directly import json data:

In tsconfig.app.json:

add "resolveJsonModule": true in "compilerOptions"

In a service or component:

import * as exampleData from '../example.json';

And then

private example = exampleData;

So, I had this recently also, for integrated security, It turns out that my issue was actually fairly simple to fix but mainly because I had forgotten to add "Trusted_Connection=True" to my connection string.

I know that may seem fairly obvious but it had me going for 20 minutes or so until I realised that I had copied my connection string format from connectionstrings.com and that portion of the connection string was missing.

Simple and I feel a bit daft, but it was the answer for me.

An interface defines behavior. For example, a Vehicle interface might define the move() method.

A Car is a Vehicle, but has additional behavior. For example, the Car interface might define the startEngine() method. Since a Car is also a Vehicle, the Car interface extends the Vehicle interface, and thus defines two methods: move() (inherited) and startEngine().

The Car interface doesn't have any method implementation. If you create a class (Volkswagen) that implements Car, it will have to provide implementations for all the methods of its interface: move() and startEngine().

An interface may not implement any other interface. It can only extend it.

Two options I just ran into:

• http://sojo.sourceforge.net/
• http://supercsv.sourceforge.net/

Create a file named filesize.cmd (and put into folder C:\Windows\System32):

@echo %~z1

I came across this error on linux environment. If not using headless then you will need

from sys import platform
    if platform != 'win32':
        from pyvirtualdisplay import Display
        display = Display(visible=0, size=(800, 600))
        display.start()

Label1.Text = dt.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");

will output:

07 Mai 2009 | 08:16 | 13 | +02:00 | +02 | +2

I'm in Denmark, my Offset from GMT is +2 hours, witch is correct.

if you need to get the CLIENT Offset, I recommend that you check a little trick that I did. The Page is in a Server in UK where GMT is +00:00 and, as you can see you will get your local GMT Offset.

Regarding you comment, I did:

DateTime dt1 = DateTime.Now;
DateTime dt2 = dt1.ToUniversalTime();

Label1.Text = dt1.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");
Label2.Text = dt2.ToString("dd MMM yyyy | hh:mm | FF | ZZZ | ZZ | Z");

and I get this:

07 Mai 2009 | 08:24 | 14 | +02:00 | +02 | +2
07 Mai 2009 | 06:24 | 14 | ZZZ | ZZ | Z 

I get no Exception, just ... it does nothing with capital Z :(

I'm sorry, but am I missing something?

Reading carefully the MSDN on Custom Date and Time Format Strings

there is no support for uppercase 'Z'.

a piece of code who work with python to read rs232 just in case somedoby else need it

ser = serial.Serial('/dev/tty.usbserial', 9600, timeout=0.5)
ser.write('*99C\r\n')
time.sleep(0.1)
ser.close()

If you really need the indices you can just do what you said again for the inner list:

l = [[2,2,2],[3,3,3],[4,4,4]]
for index1 in xrange(len(l)):
    for index2 in xrange(len(l[index1])):
        print index1, index2, l[index1][index2]

But it is more pythonic to iterate through the list itself:

for inner_l in l:
    for item in inner_l:
        print item

If you really need the indices you can also use enumerate:

for index1, inner_l in enumerate(l):
    for index2, item in enumerate(inner_l):
        print index1, index2, item, l[index1][index2]

import time 

...

def stopwatch(mins):
   # complete this whole code in some mins.
   time.sleep(60*mins)

...

To only allow numbers:

password1.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_CLASS_NUMBER);

To transform (hide) the password:

password1.setTransformationMethod(PasswordTransformationMethod.getInstance());

You're trying to access a JSON, not JSONP.

Notice the difference between your source:

https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59&callback=?

And actual JSONP (a wrapping function):

http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=processJSON&tags=monkey&tagmode=any&format=json

Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.

Rxjs v 6.*

It got simplified with newer version of rxjs .

1) Operators

import {map} from 'rxjs/operators';

2) Others

import {Observable,of, from } from 'rxjs';

Instead of chaining we need to pipe . For example

Old syntax :

source.map().switchMap().subscribe()

New Syntax:

source.pipe(map(), switchMap()).subscribe()

Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:

do -> tap,

catch -> catchError

switch -> switchAll

finally -> finalize

Rxjs v 5.*

I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.

1) import { Rx } from 'rxjs/Rx';

This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.

public cache = new Rx.BehaviorSubject('');

Or you can import individual operators .

This will Optimize your app to use only those files :

2) import { _______ } from 'rxjs/_________';

This syntax usually used for main Object like Rx itself or Observable etc.,

Keywords which can be imported with this syntax

 Observable, Observer, BehaviorSubject, Subject, ReplaySubject

3) import 'rxjs/add/observable/__________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';

These are usually accompanied with Observable directly. For example

Observable.from()
Observable.of()

Other such keywords which can be imported using this syntax:

concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of, 
range, throw, timer, using, zip

4) import 'rxjs/add/operator/_________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';

These usually come in the stream after the Observable is created. Like flatMap in this code snippet:

Observable.of([1,2,3,4])
          .flatMap(arr => Observable.from(arr));

Other such keywords using this syntax:

audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay, 
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck, 
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take, 
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip

FlatMap: flatMap is alias to mergeMap so we need to import mergeMap to use flatMap.

Note for /add imports :

We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.

When I used the Scaffold-DbContext command, it didn't include the "[key]" annotation in the model files or the "entity.HasKey(..)" entry in the "modelBuilder.Entity" blocks. My solution was to add a line like this in every "modelBuilder.Entity" block in the *Context.cs file:

entity.HasKey(X => x.Id);

I'm not saying this is better, or even the right way. I'm just saying that it worked for me.

On windows, you can use PuttyGen to load the private key file, remove the passphrase and then overwrite the existing private key file.

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

Stub, Fakes and Mocks have different meanings across different sources. I suggest you to introduce your team internal terms and agree upon their meaning.

I think it is important to distinguish between two approaches: - behaviour validation (implies behaviour substitution) - end-state validation (implies behaviour emulation)

Consider email sending in case of error. When doing behaviour validation - you check that method Send of IEmailSender was executed once. And you need to emulate return result of this method, return Id of the sent message. So you say: "I expect that Send will be called. And I will just return dummy (or random) Id for any call". This is behaviour validation: emailSender.Expect(es=>es.Send(anyThing)).Return((subject,body) => "dummyId")

When doing state validation you will need to create TestEmailSender that implements IEmailSender. And implement Send method - by saving input to some data structure that will be used for future state verification like array of some objects SentEmails and then it tests you will check that SentEmails contains expected email. This is state validation: Assert.AreEqual(1, emailSender.SentEmails.Count)

From my readings I understood that Behaviour validation usually called Mocks. And State validation usually called Stubs or Fakes.

From Microsoft's Choosing Between Class and Struct ...

As a rule of thumb, the majority of types in a framework should be classes. There are, however, some situations in which the characteristics of a value type make it more appropriate to use structs.

? CONSIDER a struct instead of a class:

• If instances of the type are small and commonly short-lived or are commonly embedded in other objects.

X AVOID a struct unless the type has all of the following characteristics:

• It logically represents a single value, similar to primitive types (int, double, etc.).
• It has an instance size under 16 bytes.
• It is immutable. (cannot be changed)
• It will not have to be boxed frequently.

If your DB table already exists and you do NOT want to include all the table's columns in your CSV file, then when you run PHP Admin Import, you'll need fill in the Column Names field in the Format-Specific Options for CSV - Shown here at the bottom of the following screenshot.

In summary:

• Choose a CSV file
• Set the Format to CSV
• Fill in the Column Names field with the names of the columns in your CSV
• If your CSV file has the column names listed in row 1, set "Skip this number of queries (for SQL) or lines (for other formats), starting from the first one" to 1

Usually that will give you the top view, but there's no guarantee that it's visible to the user. It could be off the screen, have an alpha of 0.0, or could be have size of 0x0 for example.

It could also be that the keyWindow has no subviews, so you should probably test for that first. This would be unusual, but it's not impossible.

UIWindow is a subclass of UIView, so if you want to make sure your notification is visible to the user, you can add it directly to the keyWindow using addSubview: and it will instantly be the top most view. I'm not sure if this is what you're looking to do though. (Based on your question, it looks like you already know this.)

You may want to use setArray method as mentioned in the javadoc below:

http://docs.oracle.com/javase/6/docs/api/java/sql/PreparedStatement.html#setArray(int, java.sql.Array)

Sample Code:

PreparedStatement pstmt = 
                conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", new Object[]{"1", "2","3"});
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();

Using the amazing moment.js library:

function humanizeDuration(input, units ) { 
  // units is a string with possible values of y, M, w, d, h, m, s, ms
  var duration = moment().startOf('day').add(units, input),
    format = "";

  if(duration.hour() > 0){ format += "H [hours] "; }

  if(duration.minute() > 0){ format += "m [minutes] "; }

  format += " s [seconds]";

  return duration.format(format);
}

This allows you to specify any duration be it hours, minutes, seconds, mills, and returns a human readable version.

Also, you may want to try Data::Dumper. Example:

use Data::Dumper;

# simple procedural interface
print Dumper($foo, $bar);

All I'm really interested in is the ownership and permissions information for the first level subdirectories.

I found a easy solution while playing my fish, which fits your need perfectly.

ll `ls`

or

ls -l $(ls)

The unintuitive thing about passing parameters in JSF is that you do not decide what to send (in the action), but rather what you wish to receive (in the target page).

When you do an action that ends with a redirect, the target page metadata is loaded and all required parameters are read and appended to the url as params.

Note that this is exactly the same mechanism as with any other JSF binding: you cannot read inputText's value from one place and have it write somewhere else. The value expression defined in viewParam is used both for reading (before the redirect) and for writing (after the redirect).

With your bean you just do:

@ManagedBean
@RequestScoped
public class MyBean {

private int id;

public String submit() {
    //Does stuff
    id = setID();
    return "success?faces-redirect=true&includeViewParams=true";
}

// setter and getter for id

If the receiving side has:

    <f:metadata>
        <f:viewParam name="id" value="#{myBean.id}" />
    </f:metadata>

It will do exactly what you want.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

If the data is on multiple lines then you may have to use the following,

/My cow ([\s\S]*)milk/gm

My cow always gives 
milk

Regex 101 example

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

Assuming that the items in your CheckedListBox are strings:

  for (int i = 0; i < checkedListBox1.Items.Count; i++)
  {
    if ((string)checkedListBox1.Items[i] == value)
    {
      checkedListBox1.SetItemChecked(i, true);
    }
  }

Or

  int index = checkedListBox1.Items.IndexOf(value);

  if (index >= 0)
  {
    checkedListBox1.SetItemChecked(index, true);
  }

You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:

Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
        .thenComparingInt(SomeEntity::getProperty2)
        .thenComparing(SomeEntity::getProperty3, reverseOrder());

update 2 ::slotted

::slotted is now supported by all new browsers and can be used with ViewEncapsulation.ShadowDom

https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted

update 1 ::ng-deep

/deep/ was deprecated and replaced by ::ng-deep.

::ng-deep is also already marked deprecated, but there is no replacement available yet.

When ViewEncapsulation.Native is properly supported by all browsers and supports styling accross shadow DOM boundaries, ::ng-deep will probably be discontinued.

original

Angular adds all kinds of CSS classes to the HTML it adds to the DOM to emulate shadow DOM CSS encapsulation to prevent styles of bleeding in and out of components. Angular also rewrites the CSS you add to match these added classes. For HTML added using [innerHTML] these classes are not added and the rewritten CSS doesn't match.

As a workaround try

• for CSS added to the component

/* :host /deep/ mySelector { */
:host ::ng-deep mySelector { 
  background-color: blue;
}

• for CSS added to index.html

/* body /deep/ mySelector { */
body ::ng-deep mySelector {
  background-color: green;
}

>>> (and the equivalent/deep/ but /deep/ works better with SASS) and ::shadow were added in 2.0.0-beta.10. They are similar to the shadow DOM CSS combinators (which are deprecated) and only work with encapsulation: ViewEncapsulation.Emulated which is the default in Angular2. They probably also work with ViewEncapsulation.None but are then only ignored because they are not necessary. These combinators are only an intermediate solution until more advanced features for cross-component styling is supported.

Another approach is to use

@Component({
  ...
  encapsulation: ViewEncapsulation.None,
})

for all components that block your CSS (depends on where you add the CSS and where the HTML is that you want to style - might be all components in your application)

Update

Example Plunker

I encountered a similar problem, with a syntax error that I knew should not be a syntax error. In my case it turned out that a Python 2 interpreter was trying to run Python 3 code, or vice versa; I think that my shell had a PYTHONPATH with a mixture of Python 2 and Python 3.

When just a single result is needed, then no loop should be used. Just fetch the row right away.

• In case you need to fetch the entire row into associative array:

    $row = $result->fetch_assoc();
  

• in case you need just a single value

    $row = $result->fetch_row();
    $value = $row[0] ?? false;
  

The last example will return the first column from the first returned row, or false if no row was returned. It can be also shortened to a single line,

$value = $result->fetch_row()[0] ?? false;

Below are complete examples for different use cases

Variables to be used in the query

When variables are to be used in the query, then a prepared statement must be used. For example, given we have a variable $id:

$query = "SELECT ssfullname, ssemail FROM userss WHERE ud=?";
$stmt = $conn->prepare($query);
$stmt->bind_param("s", $id);
$stmt->execute()
$result = $stmt->get_result();
$row = $result->fetch_assoc();

// in case you need just a single value
$query = "SELECT count(*) FROM userss WHERE id=?";
$stmt = $conn->prepare($query);
$stmt->bind_param("s", $id);
$stmt->execute()
$result = $stmt->get_result();
$value = $result->fetch_row()[0] ?? false;

The detailed explanation of the above process can be found in my article. As to why you must follow it is explained in this famous question

No variables in the query

In your case, where no variables to be used in the query, you can use the query() method:

$query = "SELECT ssfullname, ssemail FROM userss ORDER BY ssid";
$result = $conn->query($query);
// in case you need an array
$row = $result->fetch_assoc();
// OR in case you need just a single value
$value = $result->fetch_row()[0] ?? false;

By the way, although using raw API while learning is okay, consider using some database abstraction library or at least a helper function in the future:

// using a helper function
$sql = "SELECT email FROM users WHERE id=?";
$value = prepared_select($conn, $sql, [$id])->fetch_row[0] ?? false;

// using a database helper class
$email = $db->getCol("SELECT email FROM users WHERE id=?", [$id]);

As you can see, although a helper function can reduce the amount of code, a class' method could encapsulate all the repetitive code inside, making you to write only meaningful parts - the query, the input parameters and the desired result format (in the form of the method's name).

Use a library instead

We don't have to reinvent the wheel. Just use a library to save the time and headache.

js-base64

https://github.com/dankogai/js-base64 is good and I confirm it supports unicode very well.

Base64.encode('dankogai');  // ZGFua29nYWk=
Base64.encode('???');    // 5bCP6aO85by+
Base64.encodeURI('???'); // 5bCP6aO85by-

Base64.decode('ZGFua29nYWk=');  // dankogai
Base64.decode('5bCP6aO85by+');  // ???
// note .decodeURI() is unnecessary since it accepts both flavors
Base64.decode('5bCP6aO85by-');  // ???

Short answer for fast need

1. Implement your Class to Serializable.

If you have any inner Classes don't forget to implement them to Serializable too!!

public class SportsData implements  Serializable
public class Sport implements  Serializable

List<Sport> clickedObj;

2. Put your object into Intent

 Intent intent = new Intent(SportsAct.this, SportSubAct.class);
            intent.putExtra("sport", clickedObj);
            startActivity(intent);

3. And receive your object in the other Activity Class

Intent intent = getIntent();
    Sport cust = (Sport) intent.getSerializableExtra("sport");

You can use MutationObserver class.

MutationObserver provides developers a way to react to changes in a DOM. It is designed as a replacement for Mutation Events defined in the DOM3 Events specification.

Example (source)

// select the target node
var target = document.querySelector('#some-id');

// create an observer instance
var observer = new MutationObserver(function(mutations) {
  mutations.forEach(function(mutation) {
    console.log(mutation.type);
  });    
});

// configuration of the observer:
var config = { attributes: true, childList: true, characterData: true };

// pass in the target node, as well as the observer options
observer.observe(target, config);

// later, you can stop observing
observer.disconnect();

Now a days phonegap and cordova is owned by Adobe. Only name conversation was different. For install plugin functionality , we should use same command for phonegap and cordova too.

Command : cordova plugin add cordova-plugin-photo-library

Here,

• cordova - keyword for initiator
• plugin - initialize a plugin
• cordova plugin photo library - plugin name.

You can also find more plugin from https://cordova.apache.org/docs/en/latest/

Yup, BOOL is a typedef for a signed char according to objc.h.

I don't know about bool, though. That's a C++ thing, right? If it's defined as a signed char where 1 is YES/true and 0 is NO/false, then I imagine it doesn't matter which one you use.

Since BOOL is part of Objective-C, though, it probably makes more sense to use a BOOL for clarity (other Objective-C developers might be puzzled if they see a bool in use).

If its just a natty little app with one or two ListViews I normally just create a little helper property:

private ListViewItem SelectedItem { get { return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null); } }

If I have loads, then move it out to a helper class:

internal static class ListViewEx
{
    internal static ListViewItem GetSelectedItem(this ListView listView1)
    {
        return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null);
    }
}

so:

ListViewItem item = lstFixtures.GetSelectedItem();

The ListView interface is a bit rubbish so I normally find the helper class grows quite quickly.

The function that I use to find the length of the string is length, used as follows:

SELECT * FROM table ORDER BY length(column);

edit please see the answer further down, which is about 18 months newer, and actually solves the problem. This historically once-accurate answer is no longer as accurate. Leaving intact after the break for this reason. - thanks - jcolebrand

What edition of VS do you use? VS2008 Express, Standard, Pro or Team System? VS2010 Professional, Premium or Ultimate? I would expect that the project you downloaded was created using a higher edition of Visual Studio and uses some of those advanced features. Thus you can not open it.

EDIT: It is also possible that you lack some advanced frameworks like newer versions of Windows Mobile SDK, but if I recall correctly,the error message in such case is different.

This is an example of how to post string and file stream with HTTPClient using MultipartFormDataContent. The Content-Disposition and Content-Type need to be specified for each HTTPContent:

Here's my example. Hope it helps:

private static void Upload()
{
    using (var client = new HttpClient())
    {
        client.DefaultRequestHeaders.Add("User-Agent", "CBS Brightcove API Service");

        using (var content = new MultipartFormDataContent())
        {
            var path = @"C:\B2BAssetRoot\files\596086\596086.1.mp4";

            string assetName = Path.GetFileName(path);

            var request = new HTTPBrightCoveRequest()
                {
                    Method = "create_video",
                    Parameters = new Params()
                        {
                            CreateMultipleRenditions = "true",
                            EncodeTo = EncodeTo.Mp4.ToString().ToUpper(),
                            Token = "x8sLalfXacgn-4CzhTBm7uaCxVAPjvKqTf1oXpwLVYYoCkejZUsYtg..",
                            Video = new Video()
                                {
                                    Name = assetName,
                                    ReferenceId = Guid.NewGuid().ToString(),
                                    ShortDescription = assetName
                                }
                        }
                };

            //Content-Disposition: form-data; name="json"
            var stringContent = new StringContent(JsonConvert.SerializeObject(request));
            stringContent.Headers.Add("Content-Disposition", "form-data; name=\"json\"");
            content.Add(stringContent, "json");

            FileStream fs = File.OpenRead(path);

            var streamContent = new StreamContent(fs);
            streamContent.Headers.Add("Content-Type", "application/octet-stream");
            //Content-Disposition: form-data; name="file"; filename="C:\B2BAssetRoot\files\596090\596090.1.mp4";
            streamContent.Headers.Add("Content-Disposition", "form-data; name=\"file\"; filename=\"" + Path.GetFileName(path) + "\"");
            content.Add(streamContent, "file", Path.GetFileName(path));

            //content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");

            Task<HttpResponseMessage> message = client.PostAsync("http://api.brightcove.com/services/post", content);

            var input = message.Result.Content.ReadAsStringAsync();
            Console.WriteLine(input.Result);
            Console.Read();
        }
    }
}

Import lodash using

$ npm i --save lodash

var _ = require('lodash'); 

var objArrayList = 
    [
         { name: "user1"},
         { name: "user2"}, 
         { name: "user2"}
    ];

var Obj = _.find(objArrayList, { name: "user2" });

// Obj ==> { name: "user2"}

Use single class name something like class="active" and add it only to current page instead of all pages. If you are at Home something like below:

<ul id="navigation">
<li class="active"><a href="/">Home</a></li>
<li class=""><a href="theatre.php">Theatre</a></li>
<li class=""><a href="programming.php">Programming</a></li> 
</ul>

and your CSS like

li.active{
color: #640200;
}

Have you tried val?

$("textarea#ExampleMessage").val(result.exampleMessage);

Here's a full sample of how to parse Json content. The example takes the Android versions statistics (found from Android Studio source code here, which links to here).

Copy the "distributions.json" file you get from there into res/raw, as a fallback.

build.gradle

    implementation 'com.google.code.gson:gson:2.8.6'

manifest

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

MainActivity.kt

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        if (savedInstanceState != null)
            return
        thread {
            // https://cs.android.com/android/platform/superproject/+/studio-master-dev:tools/adt/idea/android/src/com/android/tools/idea/stats/DistributionService.java
            var root: JsonArray
            Log.d("AppLog", "loading...")
            try {
                HttpURLConnection.setFollowRedirects(true)
                val statsUrl = "https://dl.google.com/android/studio/metadata/distributions.json" //just a string
                val url = URL(statsUrl)
                val request: HttpURLConnection = url.openConnection() as HttpURLConnection
                request.connectTimeout = 3000
                request.connect()
                InputStreamReader(request.content as InputStream).use {
                    root = JsonParser.parseReader(it).asJsonArray
                }
            } catch (e: Exception) {
                Log.d("AppLog", "error while loading from Internet, so using fallback")
                e.printStackTrace()
                InputStreamReader(resources.openRawResource(R.raw.distributions)).use {
                    root = JsonParser.parseReader(it).asJsonArray
                }
            }
            val decimalFormat = DecimalFormat("0.00")
            Log.d("AppLog", "result:")

            root.forEach {
                val androidVersionInfo = it.asJsonObject
                val versionNickName = androidVersionInfo.get("name").asString
                val versionName = androidVersionInfo.get("version").asString
                val versionApiLevel = androidVersionInfo.get("apiLevel").asInt
                val marketSharePercentage = androidVersionInfo.get("distributionPercentage").asFloat * 100f
                Log.d("AppLog", "\"$versionNickName\" - $versionName - API$versionApiLevel - ${decimalFormat.format(marketSharePercentage)}%")
            }
        }
    }
}

As alternative to the dependency, you can also use this instead:

InputStreamReader(request.content as InputStream).use {
    val jsonArray = JSONArray(it.readText())
}

and the fallback:

InputStreamReader(resources.openRawResource(R.raw.distributions)).use {
    val jsonArray = JSONArray(it.readText())
}

The result of running this:

loading...

• but i already assigned values such that irp.WrmVersion = "10.4";

J.Random Coder's answer and initialize version field.

private string version = "10.4';

For anyone using Bootstrap and having this problem, they use :active:focus as well as just :active and :focus so you'll need:

element:active:focus {
    outline: 0;
}

Hopefully saved someone some time figuring that one out, banged my head for bit wondering why such a simple thing wasn't working.

I guess I'll post this answer for some variety. This technique for purging duplicates is something I picked up on for a project in Flash I'm currently working on about a month or so ago.

What you do is make an object and fill it with both a key and a value utilizing each array item. Since duplicate keys are discarded, duplicates are removed.

var nums = [1, 1, 2, 3, 3, 4, 5, 5, 6, 7, 7, 8, 9, 9, 10];
var newNums = purgeArray(nums);

function purgeArray(ar)
{
    var obj = {};
    var temp = [];
    for(var i=0;i<ar.length;i++)
    {
        obj[ar[i]] = ar[i];
    }
    for (var item in obj)
    {
        temp.push(obj[item]);
    }
    return temp;
}

There's already 5 other answers, so I don't see a need to post a sorting function.

For thoose who want to use a better maintainable solution than disruptive lightyear-long RegEx matches, I wrote up a few lines of code. Thoose who want to save bytes, stick to the RegEx variant :)

This restricts:

• No @ in string
• No dot in string
• More than 2 dots after @
• Bad chars in the username (before @)
• More than 2 @ in string
• Bad chars in domain
• Bad chars in subdomain
• Bad chars in TLD
• TLD - addresses

Anyways, it's still possible to leak through, so be sure you combine this with a server-side validation + email-link verification.

Here's the JSFiddle

 //validate email

var emailInput = $("#email").val(),
    emailParts = emailInput.split('@'),
    text = 'Enter a valid e-mail address!';

//at least one @, catches error
if (emailParts[1] == null || emailParts[1] == "" || emailParts[1] == undefined) { 

    yourErrorFunc(text);

} else {

    //split domain, subdomain and tld if existent
    var emailDomainParts = emailParts[1].split('.');

    //at least one . (dot), catches error
    if (emailDomainParts[1] == null || emailDomainParts[1] == "" || emailDomainParts[1] == undefined) { 

        yourErrorFunc(text); 

     } else {

        //more than 2 . (dots) in emailParts[1]
        if (!emailDomainParts[3] == null || !emailDomainParts[3] == "" || !emailDomainParts[3] == undefined) { 

            yourErrorFunc(text); 

        } else {

            //email user
            if (/[^a-z0-9!#$%&'*+-/=?^_`{|}~]/i.test(emailParts[0])) {

               yourErrorFunc(text);

            } else {

                //double @
                if (!emailParts[2] == null || !emailParts[2] == "" || !emailParts[2] == undefined) { 

                        yourErrorFunc(text); 

                } else {

                     //domain
                     if (/[^a-z0-9-]/i.test(emailDomainParts[0])) {

                         yourErrorFunc(text); 

                     } else {

                         //check for subdomain
                         if (emailDomainParts[2] == null || emailDomainParts[2] == "" || emailDomainParts[2] == undefined) { 

                             //TLD
                             if (/[^a-z]/i.test(emailDomainParts[1])) {

                                 yourErrorFunc(text);

                              } else {

                                 yourPassedFunc(); 

                              }

                        } else {

                             //subdomain
                             if (/[^a-z0-9-]/i.test(emailDomainParts[1])) {

                                 yourErrorFunc(text); 

                             } else {

                                  //TLD
                                  if (/[^a-z]/i.test(emailDomainParts[2])) {

                                      yourErrorFunc(text); 

                                  } else {

                                      yourPassedFunc();
}}}}}}}}}

del parentpath (or just place the .bat file inside parent folder) *.txt /s

That will delete all .txt files in the parent and all sub folders. If you want to delete multiple file extensions just add a space and do the same thing. Ex. *.txt *.dll *.xml

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

Label's aren't form elements. They don't have a value. They have innerHTML and textContent.

Thus,

$('#telefon').html() 
// or
$('#telefon').text()

or

var telefon = document.getElementById('telefon');
telefon.innerHTML;

If you are starting with your form element, check out the labels list of it. That is,

var el = $('#myformelement');
var label = $( el.prop('labels') );
// label.html();
// el.val();
// blah blah blah you get the idea

Try this code:

<form id="myform">
  <!-- form elements -->
  <a href="#" onclick="document.getElementById('myform').submit()">Submit</a>
</form>

But users with disabled JavaScript won't be able to submit the form, so you could add the following code:

<noscript>
  <input type="submit" value="Submit form!" />
</noscript>

Add a delay before focus(). 200 ms is enough

function focusAndCursor(selector){
  var input = $(selector);
  setTimeout(function() {
    // this focus on last character if input isn't empty
    tmp = input.val(); input.focus().val("").blur().focus().val(tmp);
  }, 200);
}

If you look at the documentation for JObject, you will see that it implements IEnumerable<KeyValuePair<string, JToken>>. So, you can iterate over it simply using a foreach:

foreach (var x in obj)
{
    string name = x.Key;
    JToken value = x.Value;
    …
}

$form->getErrors() works for me.

Dim connString as String ="server=localhost;userid=root;password=123456;database=uni_park_db"
Dim conn as MySqlConnection(connString)
Dim cmd as MysqlCommand
Dim dt as New DataTable
Dim ireturn as Boolean

Private Sub Insert_Car()

Dim sql as String = "insert into members_car (car_id, member_id, model, color, chassis_id, plate_number, code) values (@car_id,@member_id,@model,@color,@chassis_id,@plate_number,@code)"

Dim cmd = new MySqlCommand(sql, conn)

    cmd.Paramaters.AddwithValue("@car_id", txtCar.Text)
    cmd.Paramaters.AddwithValue("@member_id", txtMember.Text)

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

You can compile your C programs with an ARM cross-compiler:

arm-linux-gnueabi-gcc -static -march=armv7-a test.c -o test

Then you can push your compiled binary file to somewhere (don't push it in to the SD card):

adb push test /data/local/tmp/test

If you still can't access the management console after a fresh install, check if the management console was enabled. To enable it:

1. Go to the RabbitMQ command prompt.

2. Type:

   rabbitmq-plugins enable rabbitmq_management
   

UPDATE: installation without root privileges below

I advise you to not install packages manually on ubuntu system if there is already a (semi-official) repository able to solve your problem. Further, use Oracle JDK for development, just to avoid (very sporadic) compatibility issues (i've tried many years ago, it's surely better now).

Add the webupd8 repo to your system:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Install your preferred version of jdk (versions from java-6 to java-9 available):

sudo apt-get install oracle-java8-installer

You can also install multiple version of jdk, mixing openjdk and oracle versions. Then you can use the command update-java-alternatives to switch between installed version:

# list available jdk
update-java-alternatives --list

# use jdk7
sudo update-java-alternatives --set java-7-oracle

# use jdk8
sudo update-java-alternatives --set java-8-oracle

Requirements

If you get add-apt-repository: command not found be sure to have software-properties-common installed:

sudo apt-get install software-properties-common

If you're using an older version Ubuntu:

sudo apt-get install python-software-properties

JDK installation without root privileges

If you haven't administrator rights on your target machine your simplest bet is to use sdkman to install the zulu certified openjdk:

curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java

NOTE: sdkman allow to install also the official Oracle JDK, although it's not a the default option. View available versions with:

sdk ls java

Install the chosen version with:

sdk install java <version>

For example:

sdk install java 9.0.1-oracle

Glossary of commands

• sudo <command> [command_arguments]: execute a command with the superuser privilege.

• add-apt-repository <PPA_id>: Ubuntu (just like every Debian derivatives and generally speaking every Linux distribution) has a main repository of packages that handle things like package dependencies and updating. In Ubuntu is possible to extend the main repository using a PPA (Personal Package Archive) that usually contains packages not available in the system (just like oracle jdk) or updated versions of available ones (example: LibreOffice 5 in LTS is available only through this PPA).

• apt-get [install|update|upgrade|purge|...]: it's "the" command-line package handler used to manipulate the state of every repository on the system (installing / updating / upgrading can be viewed as an alteration of the repository current state).

In our case: with the command sudo add-apt-repository ppa:webupd8team/java we inform the system that the next repository update must retrieve packages information also from webupd8 repo.

With sudo apt-get update we actually update the system repository (all this operations requires superuser privileges, so we prepend sudo to the commands).

sudo apt-get install oracle-java8-installer

• update-java-alternatives (a specific java version of update-alternatives): in Ubuntu several packages provides the same functionality (browse the internet, compile mails, edit a text file or provides java/javac executables...). To allows the system to choose the user favourites tool given a specific task a mechanism using symlinks under /etc/alternatives/ is used. Try to update the jdk as indicated above (switch between java 7 and java 8) and view how change the output of this command:

  ls -l /etc/alternatives/java*

In our case: sudo update-java-alternatives --set java-8-oracle update symlinks under /etc/alternatives to point to java-8-oracle executables.

Extras:

• man <command>: start using man to read a really well written and detailed help on (almost) every shell command and its options (every command i mention in this little answer has a man page, try man update-java-alternatives).

• apt-cache search <search_key>: query the APT cache to search for a package related with the search_key provided (can be the package name or some word in package description).

• apt-cache show <package>: provides APT information for a specific package (package version, installed or not, description).

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

Add textColorHint property to your edit text

android:textColorHint="#F6F6F6"

or whichever color you want

In my case the JWT is created by a separate API so ASP.NET need only decode and validate it. In contrast to the accepted answer we're using RSA which is a non-symmetric algorithm, so the SymmetricSecurityKey class mentioned above won't work.

Here's the result.

using Microsoft.IdentityModel.Protocols;
using Microsoft.IdentityModel.Protocols.OpenIdConnect;
using Microsoft.IdentityModel.Tokens;
using System;
using System.IdentityModel.Tokens.Jwt;
using System.Threading;
using System.Threading.Tasks;

    public static async Task<JwtSecurityToken> VerifyAndDecodeJwt(string accessToken)
    {
        try
        {
            var configurationManager = new ConfigurationManager<OpenIdConnectConfiguration>($"{securityApiOrigin}/.well-known/openid-configuration", new OpenIdConnectConfigurationRetriever());
            var openIdConfig = await configurationManager.GetConfigurationAsync(CancellationToken.None);
            var validationParameters = new TokenValidationParameters()
            {
                ValidateLifetime = true,
                ValidateAudience = false,
                ValidateIssuer = false,
                RequireSignedTokens = true,
                IssuerSigningKeys = openIdConfig.SigningKeys,
            };
            new JwtSecurityTokenHandler().ValidateToken(accessToken, validationParameters, out var validToken);
            // threw on invalid, so...
            return validToken as JwtSecurityToken;
        }
        catch (Exception ex)
        {
            logger.Info(ex.Message);
            return null;
        }
    }

You may do as follows. one line of code will be enough

• let array = $('ul>li').toArray().map(item => $(item).html());

• Get the interested element

  1. get children

  2. get the array from toArray() method

  3. filter out the results you want

let array = $('ul>li').toArray().map(item => $(item).html());_x000D_
console.log(array);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<ul>_x000D_
  <li>text1</li>_x000D_
  <li>text2</li>_x000D_
  <li>text3</li>_x000D_
</ul>

I dont know if you solved this issue, but i had same issue, if the instance is local you must check the permission to access the file, but if you are accessing from your computer to a server (remote access) you have to specify the path in the server, so that means to include the file in a server directory, that solved my case

example:

BULK INSERT Table
FROM 'C:\bulk\usuarios_prueba.csv' -- This is server path not local
WITH 
  (
     FIELDTERMINATOR =',',
     ROWTERMINATOR ='\n'
  );

For Kramdown, you can use {:refdef: style="text-align: center;"} to align center

{:refdef: style="text-align: center;"}
![example](https://upload.wikimedia.org/wikipedia/en/a/a9/Example.jpg){: width="50%" .shadow}
{: refdef}
{:refdef: style="text-align: center;"}

This script will add a div that covers the entire window as the page loads. It will show a CSS-only loading spinner automatically. It will wait until the window (not the document) finishes loading, then it will wait an optional extra few seconds.

• Works with jQuery 3 (it has a new window load event)
• No image needed but it's easy to add one
• Change the delay for more branding or instructions
• Only dependency is jQuery.

My answer comes from here

You can make a derived class, which will set the timeout property of the base WebRequest class:

using System;
using System.Net;

public class WebDownload : WebClient
{
    /// <summary>
    /// Time in milliseconds
    /// </summary>
    public int Timeout { get; set; }

    public WebDownload() : this(60000) { }

    public WebDownload(int timeout)
    {
        this.Timeout = timeout;
    }

    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address);
        if (request != null)
        {
            request.Timeout = this.Timeout;
        }
        return request;
    }
}

and you can use it just like the base WebClient class.

Remove

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.16</version>
</dependency> 

slf4j-log4j12 is the log4j binding for slf4j you dont need to add another log4j dependency.

Added
Provide the log4j configuration in log4j.properties and add it to your class path. There are sample configurations here

or you can change your binding to

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.6.1</version>
</dependency>

if you are configuring slf4j due to some dependencies requiring it.

Here is another solution I have just build with css grids based on the answers in here:

In normally html5 video player will support mp4, WebM, 3gp and OGV format directly.

    <video controls>
      <source src=http://techslides.com/demos/sample-videos/small.webm type=video/webm>
      <source src=http://techslides.com/demos/sample-videos/small.ogv type=video/ogg>
      <source src=http://techslides.com/demos/sample-videos/small.mp4 type=video/mp4>
      <source src=http://techslides.com/demos/sample-videos/small.3gp type=video/3gp>
    </video>

We can add an external HLS js script in web application.

    <!DOCTYPE html>
    <html>
    <head>
    <meta charset=utf-8 />
    <title>Your title</title>
      
    
      <link href="https://unpkg.com/video.js/dist/video-js.css" rel="stylesheet">
      <script src="https://unpkg.com/video.js/dist/video.js"></script>
      <script src="https://unpkg.com/videojs-contrib-hls/dist/videojs-contrib-hls.js"></script>
       
    </head>
    <body>
      <video id="my_video_1" class="video-js vjs-fluid vjs-default-skin" controls preload="auto"
      data-setup='{}'>
        <source src="https://cdn3.wowza.com/1/ejBGVnFIOW9yNlZv/cithRSsv/hls/live/playlist.m3u8" type="application/x-mpegURL">
      </video>
      
    <script>
    var player = videojs('my_video_1');
    player.play();
    </script>
      
    </body>
    </html>

One other difference not mentioned so far is that

• with Clone() the destination array need not exist yet since a new one is created from scratch.
• with CopyTo() not only does the destination array need to already exist, it needs to be large enough to hold all the elements in the source array from the index you specify as the destination.

Copying the answer from Chris:

Got it working:

import {AfterViewInit} from 'angular2/core';    

export class HomeCmp implements AfterViewInit {    

    ngAfterViewInit() {
       //Copy in all the js code from the script.js. Typescript will complain but it works just fine
    }

Because the second element is null after you clear the list.

Use:

String s = myList.get(0);

And remember, index 0 is the first element.

If you just want to pass a class to a function, so that this function can create new instances of that class, just treat the class like any other value you would give as a parameter:

def printinstance(someclass):
  print someclass()

Result:

>>> printinstance(list)
[]
>>> printinstance(dict)
{}

String value = YourEditText.getText().toString;

I met very rare case, but hopely it could help to someone: made a proxy service, which proxied requests to another service. And every request's error was "unable to verify the first certificate" even when i added all expected certificates.

The reason was pretty simple - i accidently re-sent also the "host" header. Just make sure you don't send "host" header explicitly.

if you guys want to make a non-overflow scrollview or listview, just but it on a RelativeLayout with a topview and bottomview on top and bottom for it:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/topview"
    android:layout_below="@+id/bottomview" >

If you type:

?sample

If will launch a help menu to explain what the parameters of the sample function mean.

I am not an expert, but here is some code I have:

data <- data.frame(matrix(rnorm(400), nrow=100))
splitdata <- split(data[1:nrow(data),],sample(rep(1:4,as.integer(nrow(data)/4))))
test <- splitdata[[1]]
train <- rbind(splitdata[[1]],splitdata[[2]],splitdata[[3]])

This will give you 75% train and 25% test.

A variant of Marks (excellent) answer

• Add "using"s
• Make the class IDisposable
• Remove the URL encoding code to make the example simpler.
• Add a simple test fixture to demonstrate usage

Hope this helps

Check if there is a file called maintenance.flag and if so delete it.

Magento 1.x : maintenance.flag file is in : magento root directory

Magento 2.x : maintenance.flag file is in : var folder

When Magento is performing certain tasks it temporarily creates this file. Magento checks for its existence and if it's there will send users to the page you described.

It's supposed to automatically delete this file when done processing whatever task it was doing, but I've experienced occasions where something went wrong and it failed to delete it.

Here is an example that demonstrates the differences between pass by value - pointer value - reference:

void swap_by_value(int a, int b){
    int temp;

    temp = a;
    a = b;
    b = temp;
}   
void swap_by_pointer(int *a, int *b){
    int temp;

    temp = *a;
    *a = *b;
    *b = temp;
}    
void swap_by_reference(int &a, int &b){
    int temp;

    temp = a;
    a = b;
    b = temp;
}

int main(void){
    int arg1 = 1, arg2 = 2;

    swap_by_value(arg1, arg2);
    cout << arg1 << " " << arg2 << endl;    //prints 1 2

    swap_by_pointer(&arg1, &arg2);
    cout << arg1 << " " << arg2 << endl;    //prints 2 1

    arg1 = 1;                               //reset values
    arg2 = 2;
    swap_by_reference(arg1, arg2);
    cout << arg1 << " " << arg2 << endl;    //prints 2 1
}

The “passing by reference” method has an important limitation. If a parameter is declared as passed by reference (so it is preceded by the & sign) its corresponding actual parameter must be a variable.

An actual parameter referring to “passed by value” formal parameter may be an expression in general, so it is allowed to use not only a variable but also a literal or even a function invocation's result.

The function is not able to place a value in something other than a variable. It cannot assign a new value to a literal or force an expression to change its result.

PS: You can also check Dylan Beattie answer in the current thread that explains it in plain words.

The File class represents the "idea" of a file, not an actual handle to use for I/O. This is why the File class has a .exists() method, to tell you if the file exists or not. (How can you have a File object that doesn't exist?)

By contrast, constructing a new FileInputStream(new File("/my/file")) gives you an actual stream to read bytes from.

jQuery is a JavaScript library, The purpose of jQuery is to make code much easier to use JavaScript.

The jQuery syntax is tailor-made for selecting, A $ sign to define/access jQuery.

Its in declaration sequence must be on top then any other script included which uses jQuery

Correct position to jQuery declaration :

$(document).ready(function(){_x000D_
    console.log('hi from jQuery!');_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.3.0/js/bootstrap-datepicker.js"></script>

Above example will work perfectly because jQuery library is initialized before any other library which is using jQuery functions, including $

But if you apply it somewhere else, jQuery functions will not initialize in browser DOM and it will not able to identify any code related to jQuery, and its code starts with $ sign, so you will receive $ is not a function error.

Incorrect position for jQuery declaration:

$(document).ready(function(){_x000D_

Above code will not work because, jQuery is not declared on the top of any library which uses jQuery ready function.

If you want to insert only few rows and u have JPA Setup. You can use below

    @SpringBootApplication
        @Slf4j
        public class HospitalManagementApplication {

            public static void main(String[] args) {
                SpringApplication.run(HospitalManagementApplication.class, args);
            }            

            @Bean
            ApplicationRunner init(PatientRepository repository) {
                return (ApplicationArguments args) ->  dataSetup(repository);
            } 

            public void dataSetup(PatientRepository repository){
            //inserts

     }

Use: $("<p>Test</p>").prependTo(".inner"); Check out the .prepend documentation on jquery.com

WebKit browsers (ie Google Chrome and Safari) have a CSS solution similar to Mozilla's -moz-user-select:none

.no-select{    
    -webkit-user-select: none;
    cursor:not-allowed; /*makes it even more obvious*/
}

If you want the style to apply globally you could use the adjacent sibling combinator from css.

.my-button-style + .my-button-style {
  margin-left: 40px;
}

/* general button style */
.my-button-style {
  height: 100px;
  width: 150px;
}

Here is a fiddle: https://jsfiddle.net/caeLosby/10/

It is similar to some of the existing answers but it does not set the margin on the first button. For example in the case

<button id="btn1" class="my-button-style"/>
<button id="btn2" class="my-button-style"/>

only btn2 will get the margin.

For further information see https://developer.mozilla.org/en-US/docs/Web/CSS/Adjacent_sibling_combinator

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

You have to use Javascript submit function on your form object. Take a look in other functions.

<form action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

$a = 0;
if (isset($a)) { //$a is set because it has some value ,eg:0
    echo '$a has value';
}
if (!empty($a)) { //$a is empty because it has value 0
    echo '$a is not empty';
} else {
    echo '$a is empty';
}

I would use buildAndExpand from UriComponentsBuilder to pass all types of URI parameters.

For example:

String url = "http://test.com/solarSystem/planets/{planet}/moons/{moon}";

// URI (URL) parameters
Map<String, String> urlParams = new HashMap<>();
urlParams.put("planets", "Mars");
urlParams.put("moons", "Phobos");

// Query parameters
UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
        // Add query parameter
        .queryParam("firstName", "Mark")
        .queryParam("lastName", "Watney");

System.out.println(builder.buildAndExpand(urlParams).toUri());
/**
 * Console output:
 * http://test.com/solarSystem/planets/Mars/moons/Phobos?firstName=Mark&lastName=Watney
 */

restTemplate.exchange(builder.buildAndExpand(urlParams).toUri() , HttpMethod.PUT,
        requestEntity, class_p);

/**
 * Log entry:
 * org.springframework.web.client.RestTemplate Created PUT request for "http://test.com/solarSystem/planets/Mars/moons/Phobos?firstName=Mark&lastName=Watney"
 */

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

Use a normal javascript timer:

$(function(){
   function show_popup(){
      $("#message").slideUp();
   };
   window.setTimeout( show_popup, 5000 ); // 5 seconds
});

This will wait 5 seconds after the DOM is ready. If you want to wait until the page is actually loaded you need to use this:

$(window).load(function(){
   function show_popup(){
      $("#message").slideUp();
   };
   window.setTimeout( show_popup, 5000 ); // 5 seconds
})

EDIT: In answer to the OP's comment asking if there is a way to do it in jQuery and not use setTimeout the answer is no. But if you wanted to make it more "jQueryish" you could wrap it like this:

$.wait = function( callback, seconds){
   return window.setTimeout( callback, seconds * 1000 );
}

You could then call it like this:

$.wait( function(){ $("#message").slideUp() }, 5);

You can use this example to handle your problem:

System.out.printf( "%-15s %15s %n", "name", "lastname");
System.out.printf( "%-15s %15s %n", "Bill", "Smith");

You can play with the "%" until you find the right alignment to satisfy your needs

Gigablast offers a cheap web search API: http://www.gigablast.com/searchfeed.html

There are two possible reasons 1. If you are using HttpClient in your service you need to import HttpClientModule in your module file and mention it in the imports array.

import { HttpClientModule } from '@angular/common/http';

2. If you are using normal Http in your services you need to import HttpModule in your module file and mention it in the imports array.

   import { HttpModule } from '@angular/http'

By default, this is not available in the angular then you need to install @angular/http

If you wish you can use both HttpClientModule and HttpModule in your project.

On 6/19/2017 This worked perfect for me.

import React, { Component } from 'react'

class PrintThisComponent extends Component {
  render() {
    return (
      <div>
        <button onClick={() => window.print()}>PRINT</button>
        <p>Click above button opens print preview with these words on page</p>
      </div>
    )
  }
}

export default PrintThisComponent

If anyone is running into the default value occasionally being not populated on the page in Chrome, IE 10/11, Firefox -- try adding this attribute to your input/select field checking for the populated variable in the HTML, like so:

<input data-ng-model="vm.x" data-ng-if="vm.x !== '' && vm.x !== undefined && vm.x !== null" />

1. Android Studio users.

After running the emulator goto Tools->Android->Android device monitor

Click the Emulator Control Tab change from the location controls group.

2. Eclipse users.

First In Eclipse In Menu Select "Window" then Select "Open Perspective" then Select "DDMS". i.e Window->Open Prespective->DDMS.

You will see on Left Side Devices Panel and on Right Side you will see different tabs. Select "Emulator Control" Tab.

At bottom you will see Location Controls Panel. Select "Manual" Tab.

Enter Longitude and Latitude in Textboxs then Click Send Button. It will send the position to you emulator and the application.

3. Using telnet.

In the run command type this.

telnet localhost 5554

If you are not using windows you can use any telnet client.

After connecting with telnet use the following command to send your position to emulator.

geo fix long lat    
geo fix -121.45356 46.51119 4392

4. Use the browser based Google maps tool

There is a program that uses GWT and the Google Maps API to launch a browser-based map tool to set the GPS location in the emulator:

android-gps-emulator

Use waitpid() like this:

pid_t childPid;  // the child process that the execution will soon run inside of. 
childPid = fork();

if(childPid == 0)  // fork succeeded 
{   
   // Do something   
   exit(0); 
}

else if(childPid < 0)  // fork failed 
{    
   // log the error
}

else  // Main (parent) process after fork succeeds 
{    
    int returnStatus;    
    waitpid(childPid, &returnStatus, 0);  // Parent process waits here for child to terminate.

    if (returnStatus == 0)  // Verify child process terminated without error.  
    {
       printf("The child process terminated normally.");    
    }

    if (returnStatus == 1)      
    {
       printf("The child process terminated with an error!.");    
    }
}

Well, the first question is easy. There are many ens (Englishes) but (mostly) only one US English. One would guess there are en-CN, en-GB, en-AU. Guess there might even be Austrian English but that's more yes you can than yes there is.

To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.

JPA 1.0

With JPA 1.0, you'd have to use EntityManager#getDelegate(). But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:

org.hibernate.Session session = (Session) manager.getDelegate();

But with GlassFish, you'd have to do:

org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); 

I agree, that's horrible, and the spec is to blame here (not clear enough).

JPA 2.0

With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>) method that is to be preferred over EntityManager#getDelegate() for new applications.

So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:

Session session = entityManager.unwrap(Session.class);

I think the largely correct way, is to set css to this:

html
{
    overflow: hidden;
}

body
{
    margin: 0;
    box-sizing: border-box;
}

html, body
{
    height: 100%;
}

From the documentation:

datetime.datetime.date()

Return date object with same year, month and day.

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

specifying sdk.dir=<SDK_PATH> in local.properties in root folder solved my problem.

Well, with a quite similar task I stumbled upon this Thread. I did not see any programming language restriction and since groovy runs on a java vm: Here is how I was able to solve my Problem using Groovy.

"a.b.c.".count(".")

done.

The easiest way is probably to check the PATH environment variable of the process that is connecting to the database. Most likely the tnsnames.ora file is in first Oracle bin directory in path..\network\admin. TNS_ADMIN environment variable or value in registry (for the current Oracle home) may override this.

Using filemon like suggested by others will also do the trick.

if anyone cares there is a much better way to capture focus now, $(foo).focus(...)

>>> from datetime import datetime
>>> print(datetime.today().strftime("%H:%M %p"))
15:31 AM

Try replacing %I with %H.

The tibble package now has a dedicated function that converts row names to an explicit variable.

library(tibble)

Besides the third party products listed here, there is another one: NetLib Encryptionizer. However it works in a different way than the obfuscators. Obfuscators modify the assembly itself with a deobfuscation "engine" built into it. Encryptionizer encrypts the DLLs (Managed or Unmanaged) at the file level. So it does not modify the DLL except to encrypt it. The "engine" in this case is a kernel mode driver that sits between your application and the operating system. (Disclaimer: I am from NetLib Security)

1. It's good practice to give a parent to your QTimer to use Qt's memory management system.

2. update() is a QWidget function - is that what you are trying to call or not? http://qt-project.org/doc/qt-4.8/qwidget.html#update.

3. If number 2 does not apply, make sure that the function you are trying to trigger is declared as a slot in the header.

4. Finally if none of these are your issue, it would be helpful to know if you are getting any run-time connect errors.

USE BINARY_CHECKSUM

SELECT

    AND BINARY_CHECKSUM(Password) = BINARY_CHECKSUM(@Password)

remove href attribute:

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

just use display: table; on your case.

Building on Der Wolfs tip, I uninstalled the Oracle client and installed it again, right-clicking on the setup program, and running it as Administrator. It worked.
