I had the same issue. I came up with a simple solution. Use fragment .replace instead of fragment .add. Replacing fragment doing the same thing as adding fragment and then removing it manually.

getFragmentManager().beginTransaction().replace(fragment).commit();

instead of

getFragmentManager().beginTransaction().add(fragment).commit();

Oh, god! After spending several hours and downloading the Android sources, I have finally come to a solution.

If you look at the Activity class, you will see, that finish() method only sends back the result if there is a mParent property set to null. Otherwise the result is lost.

public void finish() {
    if (mParent == null) {
        int resultCode;
        Intent resultData;
        synchronized (this) {
            resultCode = mResultCode;
            resultData = mResultData;
        }
        if (Config.LOGV) Log.v(TAG, "Finishing self: token=" + mToken);
        try {
            if (ActivityManagerNative.getDefault()
                .finishActivity(mToken, resultCode, resultData)) {
                mFinished = true;
            }
        } catch (RemoteException e) {
            // Empty
        }
    } else {
        mParent.finishFromChild(this);
    }
}

So my solution is to set result to the parent activity if present, like that:

Intent data = new Intent();
 [...]
if (getParent() == null) {
    setResult(Activity.RESULT_OK, data);
} else {
    getParent().setResult(Activity.RESULT_OK, data);
}
finish();

I hope that will be helpful if someone looks for this problem workaround again.

Going off of tbradley22's answer, but using .map instead:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});

    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    Date date = new Date();
    Date date2 = new Date("2014/08/06 15:59:48");

    String currentDate = dateFormat.format(date).toString();
    String anyDate = dateFormat.format(date2).toString();

    System.out.println(currentDate);
    System.out.println(anyDate);

for VS2008 with feature pack update, shared_ptr can be found under namespace std::tr1.

std::tr1::shared_ptr<int> MyIntSmartPtr = new int;

of

if you had boost installation path (for example @ C:\Program Files\Boost\boost_1_40_0) added to your IDE settings:

#include <boost/shared_ptr.hpp>

Declare @variable type(size);

Set @variable = 'String' or Int ;

Example:

 Declare @id int;
 set @id = 10;

 Declare @str char(50);
 set @str='Hello' ; 

They deprecated getToken() method in the below release notes. Instead, we have to use getInstanceId.

https://firebase.google.com/docs/reference/android/com/google/firebase/iid/FirebaseInstanceId

Task<InstanceIdResult> task = FirebaseInstanceId.getInstance().getInstanceId();
task.addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
      @Override
      public void onSuccess(InstanceIdResult authResult) {
          // Task completed successfully
          // ...
          String fcmToken = authResult.getToken();
      }
});

task.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
    // Task failed with an exception
    // ...
}
});

To handle success and failure in the same listener, attach an OnCompleteListener:

task.addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
@Override
public void onComplete(@NonNull Task<InstanceIdResult> task) {
    if (task.isSuccessful()) {
        // Task completed successfully
        InstanceIdResult authResult = task.getResult();
        String fcmToken = authResult.getToken();
    } else {
        // Task failed with an exception
        Exception exception = task.getException();
    }
}
});

Also, the FirebaseInstanceIdService Class is deprecated and they came up with onNewToken method in FireBaseMessagingService as replacement for onTokenRefresh,

you can refer to the release notes here, https://firebase.google.com/support/release-notes/android

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Use this code logic to send the info to your server.
    //sendRegistrationToServer(s);
}

I found the easiest way is using str(timedelta). It will return a sting formatted like 3 days, 21:06:40.001000, and you can parse hours and minutes using simple string operations or regular expression.

The event when user releases his finger is MotionEvent.ACTION_UP. I'm not aware if there are any guidelines which prohibit using View.OnTouchListener instead of onClick(), most probably it depends of situation.

Here's a sample code:

imageButton.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP){

            // Do what you want
            return true;
        }
        return false;
    }
});

Button click event only.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
        <script language="javascript" type="text/javascript">
            $(document).ready(function () {
                $("#btnext").click(function () {                    
                    window.open("HTMLPage.htm", "PopupWindow", "width=600,height=600,scrollbars=yes,resizable=no");
                });
            });
</script>

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

Thanks for the links, Chris. I've often wondered about the specific effects of privileges like "BypassTraverseChecking" but never bothered to look them up.

I was having interesting problems getting a service to run and discovered that it didn't have access to it's files after the initial installation had been done by the administrator. I was thinking it needed something in addition to Logon As A Service until I found the file issue.

1. Disabled simple file sharing.
2. Temporarily made my service account an administrator.
3. Used the service account to take ownership of the files.
4. Remove service account from the administrators group.
5. Reboot.

During Take Ownership, it was necessary to disable inheritance of permissions from the parent directories and apply permissions recursively down the tree.

Wasn't able to find a "give ownership" option to avoid making the service account an administrator temporarily, though.

Anyway, thought I'd post this in case anyone else was going down the same road I was looking for security policy issues when it was really just filesystem rights.

Another great solution to debug the Network calls before redirecting to other pages is to select the beforeunload event break point

This way you assure to break the flow right before it redirecting it to another page, this way all network calls, network data and console logs are still there.

This solution is best when you want to check what is the response of the calls

P.S: You can also use XHR break points if you want to stop right before a specific call or any call (see image example)

We've seen in our projects that a post request with JSON and files is creating a lot of confusion between the frontend and backend developers, leading to unnecessary wastage of time.

Here's a better approach: convert file bytes array to Base64 string and send it in the JSON.

public Class UserDTO {
    private String firstName;
    private String lastName;
    private FileDTO profilePic; 
}

public class FileDTO {
    private String base64;
    // just base64 string is enough. If you want, send additional details
    private String name;
    private String type;
    private String lastModified;
}

@PostMapping("/user")
public String saveUser(@RequestBody UserDTO user) {
    byte[] fileBytes = Base64Utils.decodeFromString(user.getProfilePic().getBase64());
    ....
}

JS code to convert file to base64 string:

var reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = function () {

  const userDTO = {
    firstName: "John",
    lastName: "Wick",
    profilePic: {
      base64: reader.result,
      name: file.name,
      lastModified: file.lastModified,
      type: file.type
    }
  }
  
  // post userDTO
};
reader.onerror = function (error) {
  console.log('Error: ', error);
};

Run java with -d64 or -d32 specified, it will give you an error message if it doesn't support 64-bit or 32-bit respectively. Your JVM may support both.

It's working for me (PHP 5.6 + PDO / MySQL Server 8.0 / Windows 7 64bits)

Edit the file C:\ProgramData\MySQL\MySQL Server 8.0\my.ini:

default_authentication_plugin=mysql_native_password

Reset MySQL service on Windows, and in the MySQL Shell...

ALTER USER my_user@'%' IDENTIFIED WITH mysql_native_password BY 'password';

I do this frequently using Table Types to ensure more consistency and simplify code. You can't technically return "a table", but you can return a result set and using INSERT INTO .. EXEC ... syntax, you can clearly call a PROC and store the results into a table type. In the following example I'm actually passing a table into a PROC along with another param I need to add logic, then I'm effectively "returning a table" and can then work with that as a table variable.

/****** Check if my table type and/or proc exists and drop them ******/
IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'returnTableTypeData')
DROP PROCEDURE returnTableTypeData
GO
IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'myTableType')
DROP TYPE myTableType
GO

/****** Create the type that I'll pass into the proc and return from it ******/
CREATE TYPE [dbo].[myTableType] AS TABLE(
    [someInt] [int] NULL,
    [somenVarChar] [nvarchar](100) NULL
)
GO

CREATE PROC returnTableTypeData
    @someInputInt INT,
    @myInputTable myTableType READONLY --Must be readonly because
AS
BEGIN

    --Return the subset of data consistent with the type
    SELECT
        *
    FROM
        @myInputTable
    WHERE
        someInt < @someInputInt

END
GO


DECLARE @myInputTableOrig myTableType
DECLARE @myUpdatedTable myTableType

INSERT INTO @myInputTableOrig ( someInt,somenVarChar )
VALUES ( 0, N'Value 0' ), ( 1, N'Value 1' ), ( 2, N'Value 2' )

INSERT INTO @myUpdatedTable EXEC returnTableTypeData @someInputInt=1, @myInputTable=@myInputTableOrig

SELECT * FROM @myUpdatedTable


DROP PROCEDURE returnTableTypeData
GO
DROP TYPE myTableType
GO

I tried Noah's suggestion which leads to the best solution up to now.

Just insert \let\cleardoublepage\clearpage before all the parts with the blank pages Especially when you use \documentclass[12pt,a4paper]{book}

frederic snyers's advice \documentclass[oneside]{book} is also very good and solves the problem, but if we just want to use the book.cls or article.cls, the one would make a big difference presenting your particles.

Hence, Big support to \let\cleardoublepage\clearpage for the people who will ask the same question in the future.

var sb = new StringBuilder();
sb.Append(first);
sb.AppendLine(); // which is equal to Append(Environment.NewLine);
sb.Append(second);
return sb.ToString();

You need to provide iterables as the values for the Pandas DataFrame columns:

df2 = pd.DataFrame({'A':[a],'B':[b]})

This actually is possible, and I discovered how quite by accident while designing my first large-scale responsive design site.

<div class="wrapper">
  <div class="box">
    <img src="/logo.png" alt="">
  </div>
</div>

.wrapper { position:relative; overflow:hidden; }

.box { float:left; } //Note: 'float:right' would work too

.box > img { width:50%; }

The overflow:hidden gives the wrapper height and width, despite the floating contents, without using the clearfix hack. You can then position your content using margins. You can even make the wrapper div an inline-block.

Something in the lines of

myString.split("\\s+");

This groups all white spaces as a delimiter.

So if I have the string:

"Hello[space character][tab character]World"

This should yield the strings "Hello" and "World" and omit the empty space between the [space] and the [tab].

As VonC pointed out, the backslash should be escaped, because Java would first try to escape the string to a special character, and send that to be parsed. What you want, is the literal "\s", which means, you need to pass "\\s". It can get a bit confusing.

The \\s is equivalent to [ \\t\\n\\x0B\\f\\r].

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

You do not even need lists if your "number" values are all of the same mode. If I take Dirk Eddelbuettel's example:

> foo <- c(12, 22, 33)
> names(foo) <- c("tic", "tac", "toe")
> foo
tic tac toe
 12  22  33
> names(foo)
[1] "tic" "tac" "toe"

Lists are only required if your values are either of mixed mode (for example characters and numbers) or vectors.

For both lists and vectors, an individual element can be subsetted by name:

> foo["tac"]
tac 
 22 

Or for a list:

> foo[["tac"]]
[1] 22

For python3 where -1 indicate the value that to be decremented in each step for n in range(6,0,-1): print(n)

Element.children returns only element children, while Node.childNodes returns all node children. Note that elements are nodes, so both are available on elements.

I believe childNodes is more reliable. For example, MDC (linked above) notes that IE only got children right in IE 9. childNodes provides less room for error by browser implementors.

Take a look at this link: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html

How they work is too broad of a subject to cover in one SO post.

Here is one of the best explanations of indexes I have seen. Unfortunately it is for SQL Server and not MySQL. I'm not sure how similar the two are...

CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.

Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.

 Constant   Value               Description
 ----------------------------------------------------------------
 vbCr       Chr(13)             Carriage return
 vbCrLf     Chr(13) & Chr(10)   Carriage return–linefeed combination
 vbLf       Chr(10)             Line feed

• vbCr : - return to line beginning
  Represents a carriage-return character for print and display functions.

• vbCrLf : - similar to pressing Enter
  Represents a carriage-return character combined with a linefeed character for print and display functions.

• vbLf : - go to next line
  Represents a linefeed character for print and display functions.

Date and time input is accepted in almost any reasonable format, including ISO 8601, SQL-compatible, traditional POSTGRES, and others. For some formats, ordering of month, day, and year in date input is ambiguous and there is support for specifying the expected ordering of these fields.

In other words: just write anything and it will work.

Or check this table with all the unambiguous formats.

Use the exec() method. For example, say you have a dictionary and you want to turn each key into a variable with its original dictionary value can do the following.

Python 2

>>> c = {"one": 1, "two": 2}
>>> for k,v in c.iteritems():
...    exec("%s=%s" % (k,v))

>>> one
1
>>> two
2

Python 3

>>> c = {"one": 1, "two": 2}
>>> for k,v in c.items():
...    exec("%s=%s" % (k,v))

>>> one
1
>>> two
2

Apparently anti-virus software can also cause this error. In my case I had Windows Security's Ransomware Protection protecting my user folders which caused this error.

I have the same problem, the difference is I don't have access to the source code. I've fixed my problem by putting correct version of EntityFramework.SqlServer.dll in the bin directory of the application.

From Apache Commons library:

Answering this has been good, as the comments have led to an improvement in my own understanding of Python variables.

As noted in the comments, when you loop over a list with something like for member in my_list the member variable is bound to each successive list element. However, re-assigning that variable within the loop doesn't directly affect the list itself. For example, this code won't change the list:

my_list = [1,2,3]
for member in my_list:
    member = 42
print my_list

Output:

[1, 2, 3]

If you want to change a list containing immutable types, you need to do something like:

my_list = [1,2,3]
for ndx, member in enumerate(my_list):
    my_list[ndx] += 42
print my_list

Output:

[43, 44, 45]

If your list contains mutable objects, you can modify the current member object directly:

class C:
    def __init__(self, n):
        self.num = n
    def __repr__(self):
        return str(self.num)

my_list = [C(i) for i in xrange(3)]
for member in my_list:
    member.num += 42
print my_list

[42, 43, 44]

Note that you are still not changing the list, simply modifying the objects in the list.

You might benefit from reading Naming and Binding.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

Have you tried using the stream_context_set_option() method ?

$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'local_cert', '/etc/ssl/certs/cacert.pem');
$fp = fsockopen($host, $port, $errno, $errstr, 20, $context);

In addition, try file_get_contents() for the pem file, to make sure you have permissions to access it, and make sure the host name matches the certificate.

        FROM    V_EMPLOYEE

WHERE   rn > 0
ORDER BY
        Employee_ID

Note that this filter is redundant: ROW_NUMBER() starts from 1 and is always greater than 0.

You can take a reference on the control on the ItemCreated event, and then use it later.

It depends on how often you insert or read. You can increase the array by more than one if needed.

numberOfItems = ??

' ...

If numberOfItems+1 >= arr.Length Then
    Array.Resize(arr, arr.Length + 10)
End If

arr(numberOfItems) = newItem
numberOfItems += 1

Also for A, you only need to get the array if needed.

Dim list As List(Of Integer)(arr) ' Do this only once, keep a reference to the list
                                  ' If you create a new List everything you add an item then this will never be fast

'...

list.Add(newItem)
arrayWasModified = True

' ...

Function GetArray()

    If arrayWasModified Then
        arr = list.ToArray()
    End If

    Return Arr
End Function

If you have the time, I suggest you convert it all to List and remove arrays.

The process is a little tedious but yes it does work.

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

Just use;

$('#selectedDueDate').val(dateText).trigger('input');

li{
    margin-left:50px;
}

or replace 50px with whatever you want.

After processing the POST page, redirect the user to the same page.

On http://test.com/test.php

header('Location: http://test.com/test.php');

This will get rid of the box, as refreshing the page will not resubmit the data.

For me it worked after removing the target folder

The best thing I have found (that seems to work in all browsers) for centering an image, or any element, horizontally is to create a CSS class and include the following parameters:

CSS

.center {
    position: relative;          /* where the next element will be automatically positioned */
    display: inline-block;       /* causes element width to shrink to fit content */
    left: 50%;                   /* moves left side of image/element to center of parent element */
    transform: translate(-50%);  /* centers image/element on "left: 50%" position */
}

You can then apply the CSS class you created to your tag as follows:

HTML

<img class="center" src="image.jpg" />

You can also inline the CSS in your element(s) by doing the following:

<img style="position: relative; display: inline-block; left: 50%; transform: translate(-50%);" src ="image.jpg" />

...but I wouldn't recommend writing CSS inline because then you have to make multiple changes in all your tags using your centering CSS code if you ever want to change the style.

To identify a WebElement using xpath and javascript you have to use the evaluate() method which evaluates an xpath expression and returns a result.

document.evaluate()

document.evaluate() returns an XPathResult based on an XPath expression and other given parameters.

The syntax is:

var xpathResult = document.evaluate(
  xpathExpression,
  contextNode,
  namespaceResolver,
  resultType,
  result
);

Where:

• xpathExpression: The string representing the XPath to be evaluated.
• contextNode: Specifies the context node for the query. Common practice is to pass document as the context node.
• namespaceResolver: The function that will be passed any namespace prefixes and should return a string representing the namespace URI associated with that prefix. It will be used to resolve prefixes within the XPath itself, so that they can be matched with the document. null is common for HTML documents or when no namespace prefixes are used.
• resultType: An integer that corresponds to the type of result XPathResult to return using named constant properties, such as XPathResult.ANY_TYPE, of the XPathResult constructor, which correspond to integers from 0 to 9.
• result: An existing XPathResult to use for the results. null is the most common and will create a new XPathResult

Demonstration

As an example the Search Box within the Google Home Page which can be identified uniquely using the xpath as //*[@name='q'] can also be identified using the google-chrome-devtools Console by the following command:

$x("//*[@name='q']")

Snapshot:

The same element can can also be identified using document.evaluate() and the xpath expression as follows:

document.evaluate("//*[@name='q']", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;

Snapshot:

By default, an inline definition is only valid in the current translation unit.

If the storage class is extern, the identifier has external linkage and the inline definition also provides the external definition.

If the storage class is static, the identifier has internal linkage and the inline definition is invisible in other translation units.

If the storage class is unspecified, the inline definition is only visible in the current translation unit, but the identifier still has external linkage and an external definition must be provided in a different translation unit. The compiler is free to use either the inline or the external definition if the function is called within the current translation unit.

As the compiler is free to inline (and to not inline) any function whose definition is visible in the current translation unit (and, thanks to link-time optimizations, even in different translation units, though the C standard doesn't really account for that), for most practical purposes, there's no difference between static and static inline function definitions.

The inline specifier (like the register storage class) is only a compiler hint, and the compiler is free to completely ignore it. Standards-compliant non-optimizing compilers only have to honor their side-effects, and optimizing compilers will do these optimizations with or without explicit hints.

inline and register are not useless, though, as they instruct the compiler to throw errors when the programmer writes code that would make the optimizations impossible: An external inline definition can't reference identifiers with internal linkage (as these would be unavailable in a different translation unit) or define modifiable local variables with static storage duration (as these wouldn't share state accross translation units), and you can't take addresses of register-qualified variables.

Personally, I use the convention to mark static function definitions within headers also inline, as the main reason for putting function definitions in header files is to make them inlinable.

In general, I only use static inline function and static const object definitions in addition to extern declarations within headers.

I've never written an inline function with a storage class different from static.

I was looking for something similar and the official answer is no. However, I was able to find an interesting concept by Daniel at ExcelHero.com.

I'll be the first to admit Java can be very verbose, but I don't think this is unreasonable:

This further reduces to

showMessageDialog(null, "This is even shorter");

For me, to cut a long story short, I had inadvertently downgraded to angular-beta-16.

The let ... syntax is ONLY valid in 2.0.0-beta.17+

If you try the let syntax on anything below this version. You will generate this error.

Either upgrade to angular-beta-17 or use the #item in items syntax.

another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.

<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="#55000000"
        android:paddingBottom="15dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:textColor="@android:color/white" />

</FrameLayout>

and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:

int width= context.getResources().getDisplayMetrics().widthPixels;
    com.squareup.picasso.Picasso
            .with(context)
            .load("some url")
            .centerCrop().resize(width/2,width/2)
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(item.drawableId);

now you dont need CustomImageView Class anymore.

P.S i recommend to use ImageView in place of Type Int in class Item.

hope this help..

I encountered same problem with ORACLE 11G express on Windows. After a long time waiting I got the same error message.

My solution is to make sure the hostname in tnsnames.ora (usually it's not "localhost") and the default hostname in sql developer(usually it's "localhost") same. You can either do this by changing it in the tnsnames.ora, or filling up the same in the sql developer.

Oh, of course you need to reboot all the oracle services (just to be safe).

Hope it helps.

I came across the similar problem again on another machine, but this time above solution doesn't work. After some trying, I found restarting all the oracle related services can fix the problem. Originally when the installation is done, connection can be made. Somehow after several reboot of computer, there is problem. I change all the oracle services with start time as auto. And once I could not connect, I restart them all over again (the core service should be restarted at last order), and works fine.

Some article says it might be due to the MTS problem. Microsoft's problem. Maybe!

1. Normal Class: A Java class

2. Java Beans:

   • All properties private (use getters/setters)
   • A public no-argument constructor
   • Implements Serializable.

3. Pojo: Plain Old Java Object is a Java object not bound by any restriction other than those forced by the Java Language Specification. I.e., a POJO should not have to

   • Extend prespecified classes
   • Implement prespecified interface
   • Contain prespecified annotations

I had this, but not sure if this is correct. Could try this out also.

mysql_query("START TRANSACTION");
$flag = true;
$query = "INSERT INTO testing (myid) VALUES ('test')";

$query2 = "INSERT INTO testing2 (myid2) VALUES ('test2')";

$result = mysql_query($query) or trigger_error(mysql_error(), E_USER_ERROR);
if (!$result) {
$flag = false;
}

$result = mysql_query($query2) or trigger_error(mysql_error(), E_USER_ERROR);
if (!$result) {
$flag = false;
}

if ($flag) {
mysql_query("COMMIT");
} else {        
mysql_query("ROLLBACK");
}

Idea from here: http://www.phpknowhow.com/mysql/transactions/

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

Checking the owner of /dev/console seems to work well.

stat -f "%Su" /dev/console

You're taking name in document.getElementById() Your cb should be txt206451 (ID Attribute) not name attribute.

Or

You can have it by document.getElementsByName()

var cb = document.getElementsByName('field206451')[0]; // First one

OR

var cb = document.getElementById('txt206451');

And for setting values into hidden use document.getElementsByName() like following

var cb = document.getElementById('txt206451');
var label = document.getElementsByName('label206451')[0]; // Get the first one of index
console.log(label);
cb.addEventListener('change', function (evt) { // use change here. not neccessarily
    if (this.checked) {
        label.value = 'Thanks'
    } else {
        label.value = '0'
    }
}, false);

Demo Fiddle

There are two methods to consider which achieve the same effect for handling null pointers to C-style strings.

The ternary operator

void setvalue(const char *value)
{
    std::string mValue = value ? value : "";

}

or the humble if statement

void setvalue(const char *value)
{
    std::string mValue;
    if(value) mValue = value;

}

In both cases, value is only assigned to mValue when value is not a null pointer. In all other cases (i.e. when value is null), mValue will contain an empty string.

The ternary operator method may be useful for providing an alternative default string literal in the absence of a value from value:

std::string mValue = value ? value : "(NULL)";

Like this:

for pet in pets :
  print(pet)

In fact, Python only has foreach style for loops.

There is a method update on BaseQuery object in SQLAlchemy, which is returned by filter_by.

num_rows_updated = User.query.filter_by(username='admin').update(dict(email='[email protected]')))
db.session.commit()

The advantage of using update over changing the entity comes when there are many objects to be updated.

If you want to give add_user permission to all the admins,

rows_changed = User.query.filter_by(role='admin').update(dict(permission='add_user'))
db.session.commit()

Notice that filter_by takes keyword arguments (use only one =) as opposed to filter which takes an expression.

@Naftule - with "defiant.js", it is possible to query a JSON structure with XPath expressions. Check out this evaluator to get an idea of how it works:

http://www.defiantjs.com/#xpath_evaluator

Unlike JSONPath, "defiant.js" delivers the full-scale support of the query syntax - of XPath on JSON structures.

Iconv to the rescue.

You may try the following:

System.Globalization.CultureInfo cultureinfo =
        new System.Globalization.CultureInfo("nl-NL");
DateTime dt = DateTime.Parse(date, cultureinfo);

Use serialize and deserialize methods in SerializationUtils from commons-lang.

Unless your functions are very slow, you're going to need a very high-resolution timer. The most accurate one I know is QueryPerformanceCounter. Google it for more info. Try pushing the following into a class, call it CTimer say, then you can make an instance somewhere global and just call .StartCounter and .TimeElapsed

Option Explicit

Private Type LARGE_INTEGER
    lowpart As Long
    highpart As Long
End Type

Private Declare Function QueryPerformanceCounter Lib "kernel32" (lpPerformanceCount As LARGE_INTEGER) As Long
Private Declare Function QueryPerformanceFrequency Lib "kernel32" (lpFrequency As LARGE_INTEGER) As Long

Private m_CounterStart As LARGE_INTEGER
Private m_CounterEnd As LARGE_INTEGER
Private m_crFrequency As Double

Private Const TWO_32 = 4294967296# ' = 256# * 256# * 256# * 256#

Private Function LI2Double(LI As LARGE_INTEGER) As Double
Dim Low As Double
    Low = LI.lowpart
    If Low < 0 Then
        Low = Low + TWO_32
    End If
    LI2Double = LI.highpart * TWO_32 + Low
End Function

Private Sub Class_Initialize()
Dim PerfFrequency As LARGE_INTEGER
    QueryPerformanceFrequency PerfFrequency
    m_crFrequency = LI2Double(PerfFrequency)
End Sub

Public Sub StartCounter()
    QueryPerformanceCounter m_CounterStart
End Sub

Property Get TimeElapsed() As Double
Dim crStart As Double
Dim crStop As Double
    QueryPerformanceCounter m_CounterEnd
    crStart = LI2Double(m_CounterStart)
    crStop = LI2Double(m_CounterEnd)
    TimeElapsed = 1000# * (crStop - crStart) / m_crFrequency
End Property

You can use time.time() or time.clock() before and after the block you want to time.

import time

t0 = time.time()
code_block
t1 = time.time()

total = t1-t0

This method is not as exact as timeit (it does not average several runs) but it is straightforward.

time.time() (in Windows and Linux) and time.clock() (in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average the time elapsed by several runs, you have to manually call the function multiple times (As I think you already do in you example code and timeit does automatically when you set its number argument)

import time

def myfast():
   code

n = 10000
t0 = time.time()
for i in range(n): myfast()
t1 = time.time()

total_n = t1-t0

In Windows, as Corey stated in the comment, time.clock() has much higher precision (microsecond instead of second) and is preferred over time.time().

via dict.update() function

In case you need a declarative solution, you can use dict.update() to change values in a dict.

Either like this:

my_dict.update({'key1': 'value1', 'key2': 'value2'})

or like this:

my_dict.update(key1='value1', key2='value2')

via dictionary unpacking

Since Python 3.5 you can also use dictionary unpacking for this:

my_dict = { **my_dict, 'key1': 'value1', 'key2': 'value2'}

Note: This creates a new dictionary.

via merge operator or update operator

Since Python 3.9 you can also use the merge operator on dictionaries:

my_dict = my_dict | {'key1': 'value1', 'key2': 'value2'}

Note: This creates a new dictionary.

Or you can use the update operator:

my_dict |= {'key1': 'value1', 'key2': 'value2'}

I have a solution to a problem that may also apply to you. My database was in a state where a DROP TABLE failed because it couldn't find the table... but a CREATE TABLE also failed because MySQL thought the table existed. (This state could easily mess with your IF NOT EXISTS clause).

I eventually found this solution:

sudo mysqladmin flush-tables

For me, without the sudo, I got the following error:

mysqladmin: refresh failed; error: 'Access denied; you need the RELOAD privilege for this operation'

(Running on OS X 10.6)

Here's an example:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def self.up
    rename_table :old_table_name, :new_table_name
  end

  def self.down
    rename_table :new_table_name, :old_table_name
  end
end

I had to go and rename the model declaration file manually.

Edit:

In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def change
    rename_table :old_table_name, :new_table_name
  end 
end

(You still have to go through and manually rename your files.)

I justed faced very similar problem... BUT RegExp_Count couldn't resolved it. How many times string '16,124,3,3,1,0,' contains ',3,'? As we see 2 times, but RegExp_Count returns just 1. Same thing is with ''bbaaaacc' and when looking in it 'aa' - should be 3 times and RegExp_Count returns just 2.

select REGEXP_COUNT('336,14,3,3,11,0,' , ',3,') from dual;
select REGEXP_COUNT('bbaaaacc' , 'aa') from dual;

I lost some time to research solution on web. Couldn't' find... so i wrote my own function that returns TRUE number of occurance. Hope it will be usefull.

CREATE OR REPLACE FUNCTION EXPRESSION_COUNT( pEXPRESSION VARCHAR2, pPHRASE VARCHAR2 ) RETURN NUMBER AS
  vRET NUMBER := 0;
  vPHRASE_LENGTH NUMBER := 0;
  vCOUNTER NUMBER := 0;
  vEXPRESSION VARCHAR2(4000);
  vTEMP VARCHAR2(4000);
BEGIN
  vEXPRESSION := pEXPRESSION;
  vPHRASE_LENGTH := LENGTH( pPHRASE );
  LOOP
    vCOUNTER := vCOUNTER + 1;
    vTEMP := SUBSTR( vEXPRESSION, 1, vPHRASE_LENGTH);
    IF (vTEMP = pPHRASE) THEN        
        vRET := vRET + 1;
    END IF;
    vEXPRESSION := SUBSTR( vEXPRESSION, 2, LENGTH( vEXPRESSION ) - 1);
  EXIT WHEN ( LENGTH( vEXPRESSION ) = 0 ) OR (vEXPRESSION IS NULL);
  END LOOP;
  RETURN vRET;
END;

An ambiguous case that breaks in the absence of a semicolon:

// define a function
var fn = function () {
    //...
} // semicolon missing at this line

// then execute some code inside a closure
(function () {
    //...
})();

This will be interpreted as:

var fn = function () {
    //...
}(function () {
    //...
})();

We end up passing the second function as an argument to the first function and then trying to call the result of the first function call as a function. The second function will fail with a "... is not a function" error at runtime.

The best choice would be to use a collection, but if that is out for some reason, use arraycopy. You can use it to copy from and to the same array at a slightly different offset.

For example:

public void removeElement(Object[] arr, int removedIdx) {
    System.arraycopy(arr, removedIdx + 1, arr, removedIdx, arr.length - 1 - removedIdx);
}

Edit in response to comment:

It's not another good way, it's really the only acceptable way--any tools that allow this functionality (like Java.ArrayList or the apache utils) will use this method under the covers. Also, you REALLY should be using ArrayList (or linked list if you delete from the middle a lot) so this shouldn't even be an issue unless you are doing it as homework.

To allocate a collection (creates a new array), then delete an element (which the collection will do using arraycopy) then call toArray on it (creates a SECOND new array) for every delete brings us to the point where it's not an optimizing issue, it's criminally bad programming.

Suppose you had an array taking up, say, 100mb of ram. Now you want to iterate over it and delete 20 elements.

Give it a try...

I know you ASSUME that it's not going to be that big, or that if you were deleting that many at once you'd code it differently, but I've fixed an awful lot of code where someone made assumptions like that.

Python 2.7 :

x = None
isinstance(x, type(None))

or

isinstance(None, type(None))

==> True

To convert a data frame column to numeric you just have to do:-

factor to numeric:-

data_frame$column <- as.numeric(as.character(data_frame$column))

Also your server might just be closed. On a Mac, navigate to mySQL preference panel through the spotlight. When there, check the box to start your server when your computer starts and start the server.

Use this code everywhere for unregisterReceiver:

if (batteryNotifyReceiver != null) {
    unregisterReceiver(batteryNotifyReceiver);
    batteryNotifyReceiver = null;
}

These two packages need to be installed separately and usually can't be installed using pip...Therefore, for FreeBSD:

Download a compressed snapshot of the Ports Collection into /var/db/portsnap:
# portsnap fetch
When running Portsnap for the first time, extract the snapshot into /usr/ports:
# portsnap extract
After the first use of Portsnap has been completed as shown above, /usr/ports can be updated as needed by running:
# portsnap fetch
# portsnap update

Now Install:
cd /usr/ports/textproc/libxml2
make install clean

cd /usr/ports/textproc/libxslt
make install clean

You should be good to go...

I think there is a way to do it at definition stage like this

create table employee( id int identity, name varchar(50), primary key(id) ).. I am trying to see if there is a way to alter an existing table and make the column as Identity which does not look possible theoretically (as the existing values might need modification)

Why not to use separate func?

def func(*args, **kwargs):
    return inst.method(args, kwargs)

print pool.map(func, arr)

As @Flash Gordon mentioned in his comment, you will need to define any custom tag (as a section) in your App.config file, under <configSections>. For example, you're working on a test automation project with SpecFlow & adding <specFlow> tag, then a simplest version of App.config will look like this:

System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(4)

This method return April

If you need some special language, you can add:

<system.web>
    <globalization culture="es-ES" uiCulture="es-ES"></globalization>
     <compilation debug="true"
</system.web>

Or your preferred language.

For example, with es-ES culture:

System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(4)

Returns: Abril

Returns: Abril (in spanish, because, we configured the culture as es-ES in our webconfig file, else, you will get April)

That should work.

This is a Matlab implementation using the polar form of the Box-Muller transformation:

Function randn_box_muller.m:

function [values] = randn_box_muller(n, mean, std_dev)
    if nargin == 1
       mean = 0;
       std_dev = 1;
    end

    r = gaussRandomN(n);
    values = r.*std_dev - mean;
end

function [values] = gaussRandomN(n)
    [u, v, r] = gaussRandomNValid(n);

    c = sqrt(-2*log(r)./r);
    values = u.*c;
end

function [u, v, r] = gaussRandomNValid(n)
    r = zeros(n, 1);
    u = zeros(n, 1);
    v = zeros(n, 1);

    filter = r==0 | r>=1;

    % if outside interval [0,1] start over
    while n ~= 0
        u(filter) = 2*rand(n, 1)-1;
        v(filter) = 2*rand(n, 1)-1;
        r(filter) = u(filter).*u(filter) + v(filter).*v(filter);

        filter = r==0 | r>=1;
        n = size(r(filter),1);
    end
end

And invoking histfit(randn_box_muller(10000000),100); this is the result:

Obviously it is really inefficient compared with the Matlab built-in randn.

Groovy accepts nearly all Java syntax, so there is a spectrum of choices, as illustrated below:

// Java syntax 

Map<String,List> map1  = new HashMap<>();
List list1 = new ArrayList();
list1.add("hello");
map1.put("abc", list1); 
assert map1.get("abc") == list1;

// slightly less Java-esque

def map2  = new HashMap<String,List>()
def list2 = new ArrayList()
list2.add("hello")
map2.put("abc", list2)
assert map2.get("abc") == list2

// typical Groovy

def map3  = [:]
def list3 = []
list3 << "hello"
map3.'abc'= list3
assert map3.'abc' == list3

A simpler approach to this

At the beginning of column B, type

=UNIQUE(A:A)

Then in column C, use

=COUNTIF(A:A, B1)

and copy them in all row column C.

Edit: If that doesn't work for you, try using semicolon instead of comma:

=COUNTIF(A:A; B1)

Not really a direct answer, but I'd highly recommend using LINQPad for this kind of "exploratory" C# programming.

I have the following as a saved "query" in LINQPad:

var p = new System.Diagnostics.Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/c echo Foo && echo Bar";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardOutput.ReadToEnd().Dump();

Feel free to adapt as needed.

As per the documentation: FROM (Transact-SQL):

<join_type> ::= 
    [ { INNER | { { LEFT | RIGHT | FULL } [ OUTER ] } } [ <join_hint> ] ]
    JOIN

The keyword OUTER is marked as optional (enclosed in square brackets). In this specific case, whether you specify OUTER or not makes no difference. Note that while the other elements of the join clause is also marked as optional, leaving them out will make a difference.

For instance, the entire type-part of the JOIN clause is optional, in which case the default is INNER if you just specify JOIN. In other words, this is legal:

SELECT *
FROM A JOIN B ON A.X = B.Y

Here's a list of equivalent syntaxes:

A LEFT JOIN B            A LEFT OUTER JOIN B
A RIGHT JOIN B           A RIGHT OUTER JOIN B
A FULL JOIN B            A FULL OUTER JOIN B
A INNER JOIN B           A JOIN B

Also take a look at the answer I left on this other SO question: SQL left join vs multiple tables on FROM line?.

Perhaps the best way to explain it is with an example:

1. Alice creates topic branch A, and works on it
2. Bob creates unrelated topic branch B, and works on it
3. Alice does git checkout master && git pull. Master is already up to date.
4. Bob does git checkout master && git pull. Master is already up to date.
5. Alice does git merge topic-branch-A
6. Bob does git merge topic-branch-B
7. Bob does git push origin master before Alice
8. Alice does git push origin master, which is rejected because it's not a fast-forward merge.
9. Alice looks at origin/master's log, and sees that the commit is unrelated to hers.
10. Alice does git pull --rebase origin master
11. Alice's merge commit is unwound, Bob's commit is pulled, and Alice's commit is applied after Bob's commit.
12. Alice does git push origin master, and everyone is happy they don't have to read a useless merge commit when they look at the logs in the future.

Note that the specific branch being merged into is irrelevant to the example. Master in this example could just as easily be a release branch or dev branch. The key point is that Alice & Bob are simultaneously merging their local branches to a shared remote branch.

The other answers and comments are correct in that to examine the contents of a stream, one must add a terminal operation, thereby "consuming" the stream. However, one can do this and turn the result back into a stream, without buffering up the entire contents of the stream. Here are a couple examples:

static <T> Stream<T> throwIfEmpty(Stream<T> stream) {
    Iterator<T> iterator = stream.iterator();
    if (iterator.hasNext()) {
        return StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0), false);
    } else {
        throw new NoSuchElementException("empty stream");
    }
}

static <T> Stream<T> defaultIfEmpty(Stream<T> stream, Supplier<T> supplier) {
    Iterator<T> iterator = stream.iterator();
    if (iterator.hasNext()) {
        return StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0), false);
    } else {
        return Stream.of(supplier.get());
    }
}

Basically turn the stream into an Iterator in order to call hasNext() on it, and if true, turn the Iterator back into a Stream. This is inefficient in that all subsequent operations on the stream will go through the Iterator's hasNext() and next() methods, which also implies that the stream is effectively processed sequentially (even if it's later turned parallel). However, this does allow you to test the stream without buffering up all of its elements.

There is probably a way to do this using a Spliterator instead of an Iterator. This potentially allows the returned stream to have the same characteristics as the input stream, including running in parallel.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

Just stumbled accross this post.

Some time ago I made a suggestion on Visual Studio Connect about adding a new ??? operator.

http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/4104392-add-as-an-recursive-null-reference-check-opera

This would require some work from the framework team but don't need to alter the language but just do some compiler magic. The idea was that the compiler should change this code (syntax not allowed atm)

string product_name = Order.OrderDetails[0].Product.Name ??? "no product defined";

into this code

Func<string> _get_default = () => "no product defined"; 
string product_name = Order == null 
    ? _get_default.Invoke() 
    : Order.OrderDetails[0] == null 
        ? _get_default.Invoke() 
        : Order.OrderDetails[0].Product == null 
            ? _get_default.Invoke() 
            : Order.OrderDetails[0].Product.Name ?? _get_default.Invoke()

For null check this could look like

bool isNull = (Order.OrderDetails[0].Product ??? null) == null;

NodeJS supports http.request as a standard module: http://nodejs.org/docs/v0.4.11/api/http.html#http.request

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

If you're wondering whether to type HEAD^ or HEAD~ in your command, just use either:

They're both names for the same commit - the first parent of the current commit.

Likewise with master~ and master^ - both names for the first parent of master.

In the same way as 2 + 2 and 2 x 2 are both 4 - they're different ways of getting there, but the answer is the same.

This answers the question: What's the difference between HEAD^ and HEAD~ in Git?

If you just did a merge (so your current commit has more than one parent), or you're still interested in how the caret and tilde work, see the other answers (which I won't duplicate here) for an in-depth explanation, as well as how to use them repeatedly (e.g.HEAD~~~), or with numbers (e.g.HEAD^2). Otherwise, I hope this answer saves you some time.

:: is the scope resolution operator. It's used to specify the scope of something.

For example, :: alone is the global scope, outside all other namespaces.

some::thing can be interpreted in any of the following ways:

• some is a namespace (in the global scope, or an outer scope than the current one) and thing is a type, a function, an object or a nested namespace;
• some is a class available in the current scope and thing is a member object, function or type of the some class;
• in a class member function, some can be a base type of the current type (or the current type itself) and thing is then one member of this class, a type, function or object.

You can also have nested scope, as in some::thing::bad. Here each name could be a type, an object or a namespace. In addition, the last one, bad, could also be a function. The others could not, since functions can't expose anything within their internal scope.

So, back to your example, ::thing can be only something in the global scope: a type, a function, an object or a namespace.

The way you use it suggests (used in a pointer declaration) that it's a type in the global scope.

I hope this answer is complete and correct enough to help you understand scope resolution.

Another solution:

\d equivalent to [0-9]

Here's a simple php4-friendly implementation:

/**
* Builds an http query string.
* @param array $query  // of key value pairs to be used in the query
* @return string       // http query string.
**/
function build_http_query( $query ){

    $query_array = array();

    foreach( $query as $key => $key_value ){

        $query_array[] = urlencode( $key ) . '=' . urlencode( $key_value );

    }

    return implode( '&', $query_array );

}

In my situation this helped:

Before proceeding to execute these commands close all VS Code instances.

1. clean cache with

    npm cache clean --force
   

2. install the latest version of npm globally as admin:

    npm install -g npm@latest --force
   

3. clean cache with

    npm cache clean --force
   

4. Try to install your component once again.

I hope this works for others, if not you may also try temporarily disabling antivirus software before trying again.

This happened with me because I was using Next JS which has server side rendering. When you are using server side rendering there is no browser. Hence, there will not be any variable window or document. Hence this error shows up.

Work around :

If you are using Next JS you can use the dynamic rendering to prevent server side rendering for the component.

import dynamic from 'next/dynamic'

const DynamicComponentWithNoSSR = dynamic(() => import('../components/List'), {
  ssr: false
})

export default () => <DynamicComponentWithNoSSR />

If you are using any other server side rendering library. Then add the code that you want to run at the client side in componentDidMount. If you are using React Hooks then use useEffects in the place of componentsDidMount.

import React, {useState, useEffects} from 'react';

const DynamicComponentWithNoSSR = <>Some JSX</>

export default function App(){

[a,setA] = useState();
useEffect(() => {
    setA(<DynamicComponentWithNoSSR/>)
  });


return (<>{a}<>)
}

You can use .add() and .subtract() method to get yesterday and tomorrow date. Then use format method to get only date .format("D/M/Y"), D stand for Day, M for Month, Y for Year. Check in Moment Docs

 let currentMilli = Date.now()
 let today = Moment(currentMilli).format("D/M/Y");
 let tomorrow = Moment(currentMilli).add(1, 'days').format("D/M/Y");
 let yesterday = Moment(currentMilli).subtract(1, 'days').format("D/M/Y");

Result will be:

Current Milli - 1576693800000
today - 19/12/2019
tomorrow - 18/12/2019
yesterday - 18/12/2019

You have to mark the single letter as optional too:

([A-Z]{1})? +.*? +

or make the whole part optional

(([A-Z]{1}) +.*? +)?

You can use pandas, by transforming the list to a pd.Series then simply use .value_counts()

import pandas as pd
a = ['1', '1', '1', '1', '1', '1', '2', '2', '2', '2', '7', '7', '7', '10', '10']
a_cnts = pd.Series(a).value_counts().to_dict()

Input  >> a_cnts["1"], a_cnts["10"]
Output >> (6, 2)

Humm, what? ssh is not something built in to Windows like in most *nix cases.

You'd probably want to use Putty to begin with. And: http://kb.siteground.com/how_to_generate_an_ssh_key_on_windows_using_putty/

this will subtract ten days of the current date (before Java 8):

int x = -10;
Calendar cal = GregorianCalendar.getInstance();
cal.add( Calendar.DAY_OF_YEAR, x);
Date tenDaysAgo = cal.getTime();

If you're using Java 8 you can make use of the new Date & Time API (http://www.oracle.com/technetwork/articles/java/jf14-date-time-2125367.html):

LocalDate tenDaysAgo = LocalDate.now().minusDays(10);

For converting the new to the old types and vice versa see: Converting between java.time.LocalDateTime and java.util.Date

  return 0
}

Usage:

# your long running proccess pushed to the background
sleep 20 &

# spinner capture-previous-proccess-id string
spinner $! 'Working!'

output example:

[04/06/2020 03:22:24][      Seeding!      ]

You have to leave at least one field without fixed field, for example:

$('.data-table').dataTable ({

 "bAutoWidth": false,
 "aoColumns" : [
    null,
    null,
    null,                    
    null,
    {"sWidth": "20px"},
    { "sWidth": "20px"}]
});

You can change all, but leave only one as null, so it can stretch. If you put widths on ALL it will not work. Hope I helped somebody today!

You should do it like this:

function getResults(str) {
  $.ajax({
        url:'suggest.html',
        type:'POST',
        data: 'q=' + str,
        dataType: 'json',
        success: function( json ) {
           $.each(json, function(i, optionHtml){
              $('#myselect').append(optionHtml);
           });
        }
    });
};

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

if val is not None:
    # ...

is the Pythonic idiom for testing that a variable is not set to None. This idiom has particular uses in the case of declaring keyword functions with default parameters. is tests identity in Python. Because there is one and only one instance of None present in a running Python script/program, is is the optimal test for this. As Johnsyweb points out, this is discussed in PEP 8 under "Programming Recommendations".

As for why this is preferred to

if not (val is None):
    # ...

this is simply part of the Zen of Python: "Readability counts." Good Python is often close to good pseudocode.

I deleted all .suo and .user files and restarted VS 2008. But it didn't worked for me. The following steps worked for me.

Open project file (.csproj) in notepad.
Removed all configurations from <Configurations></COnfigurations> tag.
Then add one by one configuration and reload project in VS.
Build the project or view project properties.

Use this CSS (jsFiddle example):

input:disabled.btn:hover,
input:disabled.btn:active,
input:disabled.btn:focus {
  color: green
}

You have to write the most outer element on the left and the most inner element on the right.

.btn:hover input:disabled would select any disabled input elements contained in an element with a class btn which is currently hovered by the user.

I would prefer :disabled over [disabled], see this question for a discussion: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?

By the way, Laravel (PHP) generates the HTML - not the browser.

From the shell if you want to show all results you could do db.collection.find().toArray() to get all results without it.

public class Main {
 public static void main(String args[]) {
   String format = "|%1$-10s|%2$-10s|%3$-20s|\n";
   System.out.format(format, "A", "AA", "AAA");
   System.out.format(format, "B", "", "BBBBB");
   System.out.format(format, "C", "CCCCC", "CCCCCCCC");

   String ex[] = { "E", "EEEEEEEEEE", "E" };

   System.out.format(String.format(format, (Object[]) ex));
 }
}

differece in sizes of input doesnt effect the output

It seems to me like using a REGEX in this case would just be overkill. Why not just just strpos to find the space character. Also, there's nothing special about the space character in regular expressions, you should be able to search for it the same as you would search for any other character. That is, unless you disabled pattern whitespace, which would hardly be necessary in this case.

1. Go into your home folder.

2. Press ctrl & h to show your hidden folders.

5. Move that file to a different folder.

6. Once done, reboot your computer.

In gcc, you can label the parameter with the unused attribute.

This attribute, attached to a variable, means that the variable is meant to be possibly unused. GCC will not produce a warning for this variable.

In practice this is accomplished by putting __attribute__ ((unused)) just before the parameter. For example:

void foo(workerid_t workerId) { }

becomes

void foo(__attribute__((unused)) workerid_t workerId) { }

The ? is to allow Parameterized Query. These parameterized query is to allow type-specific value when replacing the ? with their respective value.

That's all to it.

Here's a reason of why it's better to use Parameterized Query. Basically, it's easier to read and debug.

Lets say you want to unstage changes upto n commits,

Where commit hashes are as follows:

• h1
• h2 ...
• hn
• hn+1

Then run the following command:
git reset hn

Now the HEAD will be at hn+1. Changes from h1 to hn will be unstaged.

I am a beginner tinkering on somebody else's code so please be lenient and further correct my errors. I tried your code and played with the VBA help The following worked with me:

Function currAddressTest(dataRangeTest As Range) As String

    currAddressTest = ActiveSheet.Name & "$" & dataRangeTest.Address(False, False)

End Function

When I select data source argument for my function, it is turned into Sheet1$A1:G3 format. If excel changes it to Table1[#All] reference in my formula, the function still works properly

I then used it in your function (tried to play and add another argument to be injected to WHERE...

Function SQL(dataRange As Range, CritA As String)

Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim currAddress As String



currAddress = ActiveSheet.Name & "$" & dataRange.Address(False, False)

strFile = ThisWorkbook.FullName
strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile _
& ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"

Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")

cn.Open strCon


strSQL = "SELECT * FROM [" & currAddress & "]" & _
         "WHERE [A] =  '" & CritA & "'  " & _
         "ORDER BY 1 ASC"

rs.Open strSQL, cn

SQL = rs.GetString

End Function

Hope your function develops further, I find it very useful. Have a nice day!

As Marcelo suggests:

UPDATE mytable
SET new_column = <expr containing old_column>;

If this takes too long and fails due to "snapshot too old" errors (e.g. if the expression queries another highly-active table), and if the new value for the column is always NOT NULL, you could update the table in batches:

UPDATE mytable
SET new_column = <expr containing old_column>
WHERE new_column IS NULL
AND ROWNUM <= 100000;

Just run this statement, COMMIT, then run it again; rinse, repeat until it reports "0 rows updated". It'll take longer but each update is less likely to fail.

EDIT:

A better alternative that should be more efficient is to use the DBMS_PARALLEL_EXECUTE API.

Sample code (from Oracle docs):

DECLARE
  l_sql_stmt VARCHAR2(1000);
  l_try NUMBER;
  l_status NUMBER;
BEGIN

  -- Create the TASK
  DBMS_PARALLEL_EXECUTE.CREATE_TASK ('mytask');

  -- Chunk the table by ROWID
  DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('mytask', 'HR', 'EMPLOYEES', true, 100);

  -- Execute the DML in parallel
  l_sql_stmt := 'update EMPLOYEES e 
      SET e.salary = e.salary + 10
      WHERE rowid BETWEEN :start_id AND :end_id';
  DBMS_PARALLEL_EXECUTE.RUN_TASK('mytask', l_sql_stmt, DBMS_SQL.NATIVE,
                                 parallel_level => 10);

  -- If there is an error, RESUME it for at most 2 times.
  l_try := 0;
  l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
  WHILE(l_try < 2 and l_status != DBMS_PARALLEL_EXECUTE.FINISHED) 
  LOOP
    l_try := l_try + 1;
    DBMS_PARALLEL_EXECUTE.RESUME_TASK('mytask');
    l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
  END LOOP;

  -- Done with processing; drop the task
  DBMS_PARALLEL_EXECUTE.DROP_TASK('mytask');

END;

Oracle Docs: https://docs.oracle.com/database/121/ARPLS/d_parallel_ex.htm#ARPLS67333

you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

Another possibility is

var res = /!id-[^!]*/.exec("!"+windowArray.join("!"));
return res && res[0].substr(1);

that IMO may make sense if you can have a special char delimiter (here i used "!"), the array is constant or mostly constant (so the join can be computed once or rarely) and the full string isn't much longer than the prefix searched for.

This solution needs the jQuery's data method.

1. Open Chrome's console (although any browser with jQuery loaded will work)
2. Run $._data($(".example").get(0), "events")
3. Drill down the output to find the desired event handler.
4. Right-click on "handler" and select "Show function definition"

$._data() is just accessing jQuery's data method. A more readable alternative could be jQuery._data().

Interesting point by this SO answer:

As of jQuery 1.8, the event data is no longer available from the "public API" for data. Read this jQuery blog post. You should now use this instead:

jQuery._data( elem, "events" ); elem should be an HTML Element, not a jQuery object, or selector.

Please note, that this is an internal, 'private' structure, and shouldn't be modified. Use this for debugging purposes only.

In older versions of jQuery, you might have to use the old method which is:

jQuery( elem ).data( "events" );

A version agnostic jQuery would be: (jQuery._data || jQuery.data)(elem, 'events');

Your error is happening because Object is a module, not a class. So your inheritance is screwy.

Change your import statement to:

from Object import ClassName

and your class definition to:

class Visitor(ClassName):

or

change your class definition to:

class Visitor(Object.ClassName):
   etc

Try this

$("#globalsearchstr").focus(function(){
    $(this).parent().css("background", "url('../images/r-srchbg_white.png') no-repeat");
});

If you're trying to insert in to last_accessed_on, which is a DateTime2, then your issue is with the fact that you are converting it to a varchar in a format that SQL doesn't understand.

If you modify your code to this, it should work, note the format of your date has been changed to: YYYY-MM-DD hh:mm:ss:

UPDATE  student_queues 
SET  Deleted=0, 
     last_accessed_by='raja', 
     last_accessed_on=CONVERT(datetime2,'2014-07-23 09:37:00')
WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

Or if you want to use CAST, replace with:

CAST('2014-07-23 09:37:00.000' AS datetime2)

This is using the SQL ISO Date Format.

This is the answer, hope it helps someone :)

First there are two variations on how the xml can be written:

1

<row>
    <IdInvernadero>8</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>8</IdCaracteristica1>
    <IdCaracteristica2>8</IdCaracteristica2>
    <Cantidad>25</Cantidad>
    <Folio>4568457</Folio>
</row>
<row>
    <IdInvernadero>3</IdInvernadero>
    <IdProducto>3</IdProducto>
    <IdCaracteristica1>1</IdCaracteristica1>
    <IdCaracteristica2>2</IdCaracteristica2>
    <Cantidad>72</Cantidad>
    <Folio>4568457</Folio>
</row>

Answer:

SELECT  
       Tbl.Col.value('IdInvernadero[1]', 'smallint'),  
       Tbl.Col.value('IdProducto[1]', 'smallint'),  
       Tbl.Col.value('IdCaracteristica1[1]', 'smallint'),
       Tbl.Col.value('IdCaracteristica2[1]', 'smallint'),
       Tbl.Col.value('Cantidad[1]', 'int'),
       Tbl.Col.value('Folio[1]', 'varchar(7)')
FROM   @xml.nodes('//row') Tbl(Col)  

2.

<row IdInvernadero="8" IdProducto="3" IdCaracteristica1="8" IdCaracteristica2="8" Cantidad ="25" Folio="4568457" />                         
<row IdInvernadero="3" IdProducto="3" IdCaracteristica1="1" IdCaracteristica2="2" Cantidad ="72" Folio="4568457" />

Answer:

SELECT  
       Tbl.Col.value('@IdInvernadero', 'smallint'),  
       Tbl.Col.value('@IdProducto', 'smallint'),  
       Tbl.Col.value('@IdCaracteristica1', 'smallint'),
       Tbl.Col.value('@IdCaracteristica2', 'smallint'),
       Tbl.Col.value('@Cantidad', 'int'),
       Tbl.Col.value('@Folio', 'varchar(7)')

FROM   @xml.nodes('//row') Tbl(Col)

The only thing that helped is to use a file of JSON instead of json body text. Based on How to send file contents as body entity using cURL

we can use \b as a word boundary and then; \b\d+\b

Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes. Quoting from the documentation for __dict__

A dictionary or other mapping object used to store an object's (writable) attributes.

Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:

def func():
    pass

func.temp = 1

print(func.__dict__)

class TempClass:
    a = 1
    def temp_function(self):
        pass

print(TempClass.__dict__)

will output

{'temp': 1}
{'__module__': '__main__', 
 'a': 1, 
 'temp_function': <function TempClass.temp_function at 0x10a3a2950>, 
 '__dict__': <attribute '__dict__' of 'TempClass' objects>, 
 '__weakref__': <attribute '__weakref__' of 'TempClass' objects>, 
 '__doc__': None}

I've tried all of the above nothing was working.. so I had to make my ImageView static public static ImageView texture; and then texture = (ImageView) findViewById(R.id.texture_back); , I don't think it's a good approach though but this really worked for my case :)

here's a really simple regex for that:

\W|_

and used as you need it (with a forward / slash delimiter).

preg_replace("/\W|_/", '', $string);

Test it here with this great tool that explains what the regex is doing:

http://www.regexr.com/

Locate the installation path of GlassFish. Then move to domains/domain-dir/logs/ and you'll find there the log files. If you have created the domain with NetBeans, the domain-dir is most probably called domain1.

See this link for the official GlassFish documentation about logging.

Remember that your img is not really a DOM element but a javascript expression.

1. This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions

2. In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components

   /** @jsx React.DOM */
   
   var Hello = React.createClass({
       render: function() {
           return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
       }
   });
   
   React.renderComponent(<Hello name="World" />, document.body);
   

The returned data is the binary data of the image type. If you use JavaScript to retrieve the user photo, please get the photo data as blob type in a XMLHttpRequest, and then retrieve the blob URL from the response. For your reference:

 var request = new XMLHttpRequest;
 var photoUri=config.endpoints.graphApiUri + "/v1.0/me/photo/$value";
 request.open("GET",photoUri);
 request.setRequestHeader("Authorization","Bearer "+token);
 request.responseType = "blob";
 request.onload = function (){
        if(request.readyState == 4 && request.status == 200){
               var image = document.createElement("img");
               var url = window.URL || window.webkitURL;
               var blobUrl = url.createObjectURL(request.response);
               image.src = blobUrl;
               document.getElementById("UserShow").appendChild(image);
        }
 };
 request.send(null);

Agreed with Yuri Tkachenko's answer.

I wanna point this out.

It's a pretty specific scenario. BUT it happens.

When you copy a gif before its loaded fully in some site like google images. it just gives the preview image address of that gif. Which is clearly not a gif.

So, make sure it ends with .gif extension

Here is a better and less tightly coupled way to implement an OnClickListener for a RecyclerView.

Snippet of usage:

RecyclerView recyclerView = findViewById(R.id.recycler);
recyclerView.addOnItemTouchListener(
    new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() {
      @Override public void onItemClick(View view, int position) {
        // do whatever
      }

      @Override public void onLongItemClick(View view, int position) {
        // do whatever
      }
    })
);

RecyclerItemClickListener implementation:

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;


public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
  private OnItemClickListener mListener;

  public interface OnItemClickListener {
    public void onItemClick(View view, int position);

    public void onLongItemClick(View view, int position);
  }

  GestureDetector mGestureDetector;

  public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
    mListener = listener;
    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && mListener != null) {
                mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

  @Override public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
    View childView = view.findChildViewUnder(e.getX(), e.getY());
    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
      mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
      return true;
    }
    return false;
  }

  @Override public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { }

  @Override
  public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept){}
}

You can try this, it is fully customizable.

ClipOval(
  child: Material(
    color: Colors.blue, // button color
    child: InkWell(
      splashColor: Colors.red, // inkwell color
      child: SizedBox(width: 56, height: 56, child: Icon(Icons.menu)),
      onTap: () {},
    ),
  ),
)

Output:

Since you asked for decimal numbers validation, for completeness' sake, I'd use a regex that doesn't allow strings like 06.05.

^((0(\.\d{1,2})?)|([1-9]\d*(\.\d{1,2})?))$

Slightly more complicated, but returns false in that case.

I had all my settings covered in the accepted answer. The problem I had was that I was trying to update the Entity Framework entity type "Task" like:

public IHttpActionResult Post(Task task)

What worked for me was to create my own entity "DTOTask" like:

public IHttpActionResult Post(DTOTask task)

You should above all never manually copy/download/move/include the individual servletcontainer-specific libraries like servlet-api.jar

@BalusC,

I would prefer to use the exact classes that my application is going to use rather than one provided by Eclipse (when I am feeling like a paranoid developer).

Another solution would be to use Eclipse "Configure Build Path" > Libraries > Add External Jars, and add servlet api of whatever Container one chooses to use.

And follow @kaustav datta's solution when using ant to build - have a property like tomcat.home or weblogic.home. However it introduces another constraint that the developer must install Weblogic on his/her local machine if weblogic is being used ! Any other cleaner solution?

This worked for me on Windows

1. download PDFtk free from https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
   
2. drop folder (PDFtk) into the root of c:
   

3. add the following to your php code where $file1 is the location and name of the first PDF file, $file2 is the location and name of the second and $newfile is the location and name of the destination file

   $file1 = ' c:\\\www\\\folder1\\\folder2\\\file1.pdf';  
   $file2 = ' c:\\\www\\\folder1\\\folder2\\\file2.pdf';  
   $file3 = ' c:\\\www\\\folder1\\\folder2\\\file3.pdf';   
   
   $command =  'cmd /c C:\\\pdftk\\\bin\\\pdftk.exe '.$file1.$file2.$newfile;
   $result = exec($command);
   

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

WebApiConfig.Register(GlobalConfiguration.Configuration);

Should be first in App_start event. I have tried it at last position in APP_start event, but that did not work.

Most people here seem to be unaware that decimal considers trailing zeroes as significant for storage and printing.

So 0.1m, 0.10m and 0.100m may compare as equal, they are stored differently (as value/scale 1/1, 10/2 and 100/3, respectively), and will be printed as 0.1, 0.10 and 0.100, respectively, by ToString().

As such, the solutions that report "too high a precision" are actually reporting the correct precision, on decimal's terms.

In addition, math-based solutions (like multiplying by powers of 10) will likely be very slow (decimal is ~40x slower than double for arithmetic, and you don't want to mix in floating-point either because that's likely to introduce imprecision). Similarly, casting to int or long as a means of truncating is error-prone (decimal has a much greater range than either of those - it's based around a 96-bit integer).

While not elegant as such, the following will likely be one of the fastest way to get the precision (when defined as "decimal places excluding trailing zeroes"):

public static int PrecisionOf(decimal d) {
  var text = d.ToString(System.Globalization.CultureInfo.InvariantCulture).TrimEnd('0');
  var decpoint = text.IndexOf('.');
  if (decpoint < 0)
    return 0;
  return text.Length - decpoint - 1;
}

The invariant culture guarantees a '.' as decimal point, trailing zeroes are trimmed, and then it's just a matter of seeing of how many positions remain after the decimal point (if there even is one).

Edit: changed return type to int

Enter SQL*Plus with:

sqlplus /nolog

And then:

connect sys@<SID> AS sysdba

trainosais - you are right, validation should be done on a directive level. It's clean, modular and allows for reusability of code. When you have basic validation like that in a controller you have write it over and over again for different forms. That's super anti-dry.

I had a similar problem recently and sorted it out with a simple directive, which plugs in to the parsers pipeline, therefore stays consistent with Angular architecture. Chaining validators makes it very easy to reuse and that should be considered the only solution in my view.

Without further ado, here's the simplified markup:

<form novalidate="novalidate">
    <label>email</label>
    <input type="text"
        ng-model="email"
        name="email" />
    <label>email repeated</label>
    <input ng-model="emailRepeated"
        same-as="email"
        name="emailRepeated" />
</form>

And the JS code:

angular.module('app', [])
    .directive('sameAs', function() {
        return {
            require: 'ngModel',
            link: function(scope, elem, attrs, ngModel) {
                ngModel.$parsers.unshift(validate);

                // Force-trigger the parsing pipeline.
                scope.$watch(attrs.sameAs, function() {
                    ngModel.$setViewValue(ngModel.$viewValue);
                });

                function validate(value) {
                    var isValid = scope.$eval(attrs.sameAs) == value;

                    ngModel.$setValidity('same-as', isValid);

                    return isValid ? value : undefined;
                }
            }
        };
    });

The directive hooks into the parsers pipeline in order to get notified of any changes to the view value and set validity based on comparison of the new view value and the value of the reference field. That bit is easy. The tricky bit is sniffing for changes on the reference field. For that the directive sets a watcher on the reference value and force-triggeres the parsing pipeline, in order to get all the validators run again.

I made a bit more of a generic filter that I've used in multiple projects already:

• object = the object that needs to be filtered
• field = the field within that object that we'll filter on
• filter = the value of the filter that needs to match the field

HTML:

<input ng-model="customerNameFilter" />
<div ng-repeat="(key, value) in filter(customers, 'customerName', customerNameFilter" >
   <p>Number: {{value.customerNo}}</p>
   <p>Name: {{value.customerName}}</p>
</div>

JS:

  $scope.filter = function(object, field, filter) {
    if (!object) return {};
    if (!filter) return object;

    var filteredObject = {};
    Object.keys(object).forEach(function(key) {
      if (object[key][field] === filter) {
        filteredObject[key] = object[key];
      }
    });

    return filteredObject;
  };

Maybe you could find that out by looking at the query log.

jQuery's id selector only returns one result. The descendant and multiple selectors in the second and third statements are designed to select multiple elements. It's similar to:

Statement 1

var length = document.getElementById('a').length;

...Yields one result.

Statement 2

var length = 0;
for (i=0; i<document.body.childNodes.length; i++) {
    if (document.body.childNodes.item(i).id == 'a') {
        length++;
    }
}

...Yields two results.

Statement 3

var length = document.getElementById('a').length + document.getElementsByTagName('div').length;

...Also yields two results.

When you aren't sure which syntax to choose, especially when there doesn't seem to be much to separate the choices, consult a book on heuristics. As far as I know, the only heuristics book for SQL is 'Joe Celko's SQL Programming Style':

A correlation name is more often called an alias, but I will be formal. In SQL-92, they can have an optional AS operator, and it should be used to make it clear that something is being given a new name. [p16]

This way, if your team doesn't like the convention, you can blame Celko -- I know I do ;)

UPDATE 1: IIRC for a long time, Oracle did not support the AS (preceding correlation name) keyword, which may explain why some old timers don't use it habitually.

UPDATE 2: the term 'correlation name', although used by the SQL Standard, is inappropriate. The underlying concept is that of a ‘range variable’.

UPDATE 3: I just re-read what Celko wrote and he is wrong: the table is not being renamed! I now think:

A correlation name is more often called an alias, but I will be formal. In Standard SQL they can have an optional AS keyword but it should not be used because it may give the impression that something is being renamed when it is not. In fact, it should be omitted to enforce the point that it is a range variable.

In the term of SEO , 301 and 302 both are good it is depend on situation,

If only one version can be returned (i.e., the other redirects to it), that’s great! This behavior is beneficial because it reduces duplicate content. In the particular case of redirects to trailing slash URLs, our search results will likely show the version of the URL with the 200 response code (most often the trailing slash URL) -- regardless of whether the redirect was a 301 or 302.

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

Adding a 1px transparent border will trigger anti-aliasing

outline: 1px solid transparent;

Alternatively, add a 1px transparent box-shadow.

box-shadow: 0 0 1px rgba(255,255,255,0);

Flat Assembler does not need an extra linker. This makes assembler programming quite easy. It is also available for Linux.

This is hello.asm from the Fasm examples:

include 'win32ax.inc'

.code

  start:
    invoke  MessageBox,HWND_DESKTOP,"Hi! I'm the example program!",invoke GetCommandLine,MB_OK
    invoke  ExitProcess,0

.end start

Fasm creates an executable:

>fasm hello.asm
flat assembler  version 1.70.03  (1048575 kilobytes memory)
4 passes, 1536 bytes.

And this is the program in IDA:

You can see the three calls: GetCommandLine, MessageBox and ExitProcess.

If, like me, you are following the Android tutorial on http://developer.android.com/training/basics/actionbar/setting-up.html and keep getting this error, try to change the AppBaseTheme style in all styles.xml files. In detail:

1. In file res/values/styles.xml change the line:

   <style name="AppBaseTheme" parent="android:Theme.Light">
   

   to:

   <style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">
   

2. In file res/values-v11/styles.xml change the line:

   <style name="AppBaseTheme" parent="android:Theme.Holo.Light">
   

   to:

   <style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light">
   

3. In file res/values-v14/styles.xml change the line:

   <style name="AppBaseTheme" parent="android:Theme.Holo.Light.DarkActionBar">
   

   to:

   <style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
   

Now the application should run fine.

hope you are doing well. you can use my code to crop image.you just have to make a class and use this class into your XMl and java classes. Crop image. you can crop your selected image into circle and square into many of option. hope fully it will works for you.because this is totally manageable for you and you can change it according to you.

enjoy your work :)

Does playsinline attribute help?

This should be enough to answer your question: http://docs.oracle.com/javase/tutorial/java/IandI/objectclass.html

The equals() method compares two objects for equality and returns true if they are equal. The equals() method provided in the Object class uses the identity operator (==) to determine whether two objects are equal. For primitive data types, this gives the correct result. For objects, however, it does not. The equals() method provided by Object tests whether the object references are equal—that is, if the objects compared are the exact same object.

To test whether two objects are equal in the sense of equivalency (containing the same information), you must override the equals() method.

it is php version the problem, had the same issue upgraded my php version to 5.6 solved the problem

background: rgba(0,0,0,.5);

you can use rgba for opacity, will only work in ie9+ and better browsers

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

To populate the array:

int[] numbers = new int[100];
for (int i = 0; i < 100; i++) {
    numbers[i] = i+1;
}

and then to sum it:

int ans = 0;
for (int i = 0; i < numbers.length; i++) {
    ans += numbers[i];
}

or in short, if you want the sum from 1 to n:

( n ( n +1) ) / 2

This is a part from a REST-Service I´ve written recently.

var select = $("#productSelect")
for (var prop in data) {
    var option = document.createElement('option');
    option.innerHTML = data[prop].ProduktName
    option.value = data[prop].ProduktName;
    select.append(option)
}

The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.

You can set the timeout on the HTTP Client like this

int connectionTimeout=5000;
int socketTimeout=15000;
ApacheHttpClient.Factory clientFactory = new ApacheHttpClient.Factory(new HttpClientFactory(connectionTimeout, socketTimeout));
HttpCommandExecutor executor =
      new HttpCommandExecutor(new HashMap<String, CommandInfo>(), new URL(seleniumServerUrl), clientFactory);
RemoteWebDriver driver = new RemoteWebDriver(executor, capabilities);

With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:

http://bootply.com/74352

JS file:

var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();

ToEndDate.setDate(ToEndDate.getDate()+365);

$('.from_date').datepicker({

    weekStart: 1,
    startDate: '01/01/2012',
    endDate: FromEndDate, 
    autoclose: true
})
    .on('changeDate', function(selected){
        startDate = new Date(selected.date.valueOf());
        startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
        $('.to_date').datepicker('setStartDate', startDate);
    }); 
$('.to_date')
    .datepicker({

        weekStart: 1,
        startDate: startDate,
        endDate: ToEndDate,
        autoclose: true
    })
    .on('changeDate', function(selected){
        FromEndDate = new Date(selected.date.valueOf());
        FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
        $('.from_date').datepicker('setEndDate', FromEndDate);
    });

HTML:

<input class="from_date" placeholder="Select start date" contenteditable="false" type="text">
<input class="to_date" placeholder="Select end date" contenteditable="false" type="text" 

And do not forget to include bootstrap datepicker.js and .css files aswell.

You can also use the command line, Change directory where your folder is located then type the following :

     git init
     git add <folder1> <folder2> <etc.>
     git commit -m "Your message about the commit"
     git remote add origin https://github.com/yourUsername/yourRepository.git
     git push -u origin master
     git push origin master  

I don't think any of these answers meet my need, unless I am fundamentally misunderstanding something.

I have an app (originally an iPad app) that I want to run both on an iPad and on the Mac, under Catalyst. I'm using the plist option to scale the Mac interface to match the iPad, but would like to migrate to AppKit if that is reasonable. When running on a Mac, I believe that all of the aforementioned approaches tell me that I'm on an iPad. The Catalyst fake-out is pretty thorough.

For most concerns I indeed understand that the code should pretend it's on an iPad when thus running on a Mac. One exception is that the rolling picker is not available on the Mac under Catalyst, but is on the iPad. I want to figure out whether to create a UIPickerView or to do something different, at run time. Run-time selection is crucial because I want to use a single binary to run both on the iPad and Mac in the long term, while making the best use of the supported UI standards on each.

The APIs give potentially misleading results to the casual pre-Catalyst reader. For example, [UIDevice currentDevice].model returns @"iPad" when running under Catalyst on a Mac. The user interface idiom APIs sustain the same illusion.

I found that you really need to look deeper. I start with this information:

NSString *const deviceModel = [UIDevice currentDevice].model;
NSProcessInfo *const processInfo = [[NSProcessInfo alloc] init];
const bool isIosAppOnMac = processInfo.iOSAppOnMac;  // Note: this will be "no" under Catalyst
const bool isCatalystApp = processInfo.macCatalystApp;

Then you can combine these queries with expressions like [deviceModel hasPrefix: @"iPad"] to sort out the kinds of subtleties I'm facing. For my case, I explicitly want to avoid making a UIPickerView if the indicated isCatalystApp is true, independent of "misleading" information about the interface idiom, or the illusions sustained by isIosAppOnMac and deviceModel.

Now I'm curious what happens if I move the Mac app to run over on my iPad sidecar...

Some type of input hasn't got the :after or :before pseudo-element, so you can use a background-image with an SVG text element:

    input {
       background-image:url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' version='1.1' height='50px' width='120px'><text x='0' y='15' fill='gray' font-size='15'>Type Something...</text></svg>");
       background-repeat: no-repeat;
    }

    input:focus {
       background-image: none;
    }

Destructors in C++ automatically gets called in the order of their constructions (Derived then Base) only when the Base class destructor is declared virtual.

If not, then only the base class destructor is invoked at the time of object deletion.

Example: Without virtual Destructor

#include <iostream>

using namespace std;

class Base{
public:
  Base(){
    cout << "Base Constructor \n";
  }

  ~Base(){
    cout << "Base Destructor \n";
  }

};

class Derived: public Base{
public:
  int *n;
  Derived(){
    cout << "Derived Constructor \n";
    n = new int(10);
  }

  void display(){
    cout<< "Value: "<< *n << endl;
  }

  ~Derived(){
    cout << "Derived Destructor \n";
  }
};

int main() {

 Base *obj = new Derived();  //Derived object with base pointer
 delete(obj);   //Deleting object
 return 0;

}

Output

Base Constructor
Derived Constructor
Base Destructor

Example: With Base virtual Destructor

#include <iostream>

using namespace std;

class Base{
public:
  Base(){
    cout << "Base Constructor \n";
  }

  //virtual destructor
  virtual ~Base(){
    cout << "Base Destructor \n";
  }

};

class Derived: public Base{
public:
  int *n;
  Derived(){
    cout << "Derived Constructor \n";
    n = new int(10);
  }

  void display(){
    cout<< "Value: "<< *n << endl;
  }

  ~Derived(){
    cout << "Derived Destructor \n";
    delete(n);  //deleting the memory used by pointer
  }
};

int main() {

 Base *obj = new Derived();  //Derived object with base pointer
 delete(obj);   //Deleting object
 return 0;

}

Output

Base Constructor
Derived Constructor
Derived Destructor
Base Destructor

It is recommended to declare base class destructor as virtual otherwise, it causes undefined behavior.

Reference: Virtual Destructor

It's important to understand that there are two aspects to thread safety.

1. execution control, and
2. memory visibility

The first has to do with controlling when code executes (including the order in which instructions are executed) and whether it can execute concurrently, and the second to do with when the effects in memory of what has been done are visible to other threads. Because each CPU has several levels of cache between it and main memory, threads running on different CPUs or cores can see "memory" differently at any given moment in time because threads are permitted to obtain and work on private copies of main memory.

Using synchronized prevents any other thread from obtaining the monitor (or lock) for the same object, thereby preventing all code blocks protected by synchronization on the same object from executing concurrently. Synchronization also creates a "happens-before" memory barrier, causing a memory visibility constraint such that anything done up to the point some thread releases a lock appears to another thread subsequently acquiring the same lock to have happened before it acquired the lock. In practical terms, on current hardware, this typically causes flushing of the CPU caches when a monitor is acquired and writes to main memory when it is released, both of which are (relatively) expensive.

Using volatile, on the other hand, forces all accesses (read or write) to the volatile variable to occur to main memory, effectively keeping the volatile variable out of CPU caches. This can be useful for some actions where it is simply required that visibility of the variable be correct and order of accesses is not important. Using volatile also changes treatment of long and double to require accesses to them to be atomic; on some (older) hardware this might require locks, though not on modern 64 bit hardware. Under the new (JSR-133) memory model for Java 5+, the semantics of volatile have been strengthened to be almost as strong as synchronized with respect to memory visibility and instruction ordering (see http://www.cs.umd.edu/users/pugh/java/memoryModel/jsr-133-faq.html#volatile). For the purposes of visibility, each access to a volatile field acts like half a synchronization.

Under the new memory model, it is still true that volatile variables cannot be reordered with each other. The difference is that it is now no longer so easy to reorder normal field accesses around them. Writing to a volatile field has the same memory effect as a monitor release, and reading from a volatile field has the same memory effect as a monitor acquire. In effect, because the new memory model places stricter constraints on reordering of volatile field accesses with other field accesses, volatile or not, anything that was visible to thread A when it writes to volatile field f becomes visible to thread B when it reads f.

-- JSR 133 (Java Memory Model) FAQ

So, now both forms of memory barrier (under the current JMM) cause an instruction re-ordering barrier which prevents the compiler or run-time from re-ordering instructions across the barrier. In the old JMM, volatile did not prevent re-ordering. This can be important, because apart from memory barriers the only limitation imposed is that, for any particular thread, the net effect of the code is the same as it would be if the instructions were executed in precisely the order in which they appear in the source.

One use of volatile is for a shared but immutable object is recreated on the fly, with many other threads taking a reference to the object at a particular point in their execution cycle. One needs the other threads to begin using the recreated object once it is published, but does not need the additional overhead of full synchronization and it's attendant contention and cache flushing.

// Declaration
public class SharedLocation {
    static public SomeObject someObject=new SomeObject(); // default object
    }

// Publishing code
// Note: do not simply use SharedLocation.someObject.xxx(), since although
//       someObject will be internally consistent for xxx(), a subsequent 
//       call to yyy() might be inconsistent with xxx() if the object was 
//       replaced in between calls.
SharedLocation.someObject=new SomeObject(...); // new object is published

// Using code
private String getError() {
    SomeObject myCopy=SharedLocation.someObject; // gets current copy
    ...
    int cod=myCopy.getErrorCode();
    String txt=myCopy.getErrorText();
    return (cod+" - "+txt);
    }
// And so on, with myCopy always in a consistent state within and across calls
// Eventually we will return to the code that gets the current SomeObject.

Speaking to your read-update-write question, specifically. Consider the following unsafe code:

public void updateCounter() {
    if(counter==1000) { counter=0; }
    else              { counter++; }
    }

Now, with the updateCounter() method unsynchronized, two threads may enter it at the same time. Among the many permutations of what could happen, one is that thread-1 does the test for counter==1000 and finds it true and is then suspended. Then thread-2 does the same test and also sees it true and is suspended. Then thread-1 resumes and sets counter to 0. Then thread-2 resumes and again sets counter to 0 because it missed the update from thread-1. This can also happen even if thread switching does not occur as I have described, but simply because two different cached copies of counter were present in two different CPU cores and the threads each ran on a separate core. For that matter, one thread could have counter at one value and the other could have counter at some entirely different value just because of caching.

What's important in this example is that the variable counter was read from main memory into cache, updated in cache and only written back to main memory at some indeterminate point later when a memory barrier occurred or when the cache memory was needed for something else. Making the counter volatile is insufficient for thread-safety of this code, because the test for the maximum and the assignments are discrete operations, including the increment which is a set of non-atomic read+increment+write machine instructions, something like:

MOV EAX,counter
INC EAX
MOV counter,EAX

Volatile variables are useful only when all operations performed on them are "atomic", such as my example where a reference to a fully formed object is only read or written (and, indeed, typically it's only written from a single point). Another example would be a volatile array reference backing a copy-on-write list, provided the array was only read by first taking a local copy of the reference to it.

I personally prefer using char(1) with values 'Y' and 'N' for databases that don't have a native type for boolean. Letters are more user frendly than numbers which assume that those reading it will now that 1 corresponds to true and 0 corresponds to false.

'Y' and 'N' also maps nicely when using (N)Hibernate.

Here is a benchmark showing that using str.lower is faster than the accepted answer's proposed method (libc.strcasecmp):

#!/usr/bin/env python2.7
import random
import timeit

from ctypes import *
libc = CDLL('libc.dylib') # change to 'libc.so.6' on linux

with open('/usr/share/dict/words', 'r') as wordlist:
    words = wordlist.read().splitlines()
random.shuffle(words)
print '%i words in list' % len(words)

setup = 'from __main__ import words, libc; gc.enable()'
stmts = [
    ('simple sort', 'sorted(words)'),
    ('sort with key=str.lower', 'sorted(words, key=str.lower)'),
    ('sort with cmp=libc.strcasecmp', 'sorted(words, cmp=libc.strcasecmp)'),
]

for (comment, stmt) in stmts:
    t = timeit.Timer(stmt=stmt, setup=setup)
    print '%s: %.2f msec/pass' % (comment, (1000*t.timeit(10)/10))

typical times on my machine:

235886 words in list
simple sort: 483.59 msec/pass
sort with key=str.lower: 1064.70 msec/pass
sort with cmp=libc.strcasecmp: 5487.86 msec/pass

So, the version with str.lower is not only the fastest by far, but also the most portable and pythonic of all the proposed solutions here. I have not profiled memory usage, but the original poster has still not given a compelling reason to worry about it. Also, who says that a call into the libc module doesn't duplicate any strings?

NB: The lower() string method also has the advantage of being locale-dependent. Something you will probably not be getting right when writing your own "optimised" solution. Even so, due to bugs and missing features in Python, this kind of comparison may give you wrong results in a unicode context.

I'm not positive how the input fields did not trigger when I emptied the fields. But I managed to trigger each required field individually using:

        /*$.validator.unobtrusive.parse($('#saveForm'));*/
        $('#NodeZoomLevel').valid();
        $('#ZoomLevel').valid();
        $('#CenterLatitude').valid();
        $('#CenterLongitude').valid();
        $('#NodeIconSize').valid();
        $('#SaveDashboard').valid();

According to Documentation

git diff Shows changes between the working tree and the index or a tree, changes between the index and a tree, changes between two trees, changes resulting from a merge, changes between two blob objects, or changes between two files on disk.

In git diff - There's a significant difference between two dots .. and 3 dots ... in the way we compare branches or pull requests in our repository. I'll give you an easy example which demonstrates it easily.

Example: Let's assume we're checking out new branch from master and pushing some code in.

  G---H---I feature (Branch)
 /
A---B---C---D master (Branch)

• Two dots - If we want to show the diffs between all changes happened in the current time on both sides, We would use the git diff origin/master..feature or just git diff origin/master
  ,output: ( H, I against A, B, C, D )

• Three dots - If we want to show the diffs between the last common ancestor (A), aka the check point we started our new branch ,we use git diff origin/master...feature,output: (H, I against A ).

• I'd rather use the 3 dots in most circumstances.

Maybe not what you were looking for, but perhaps nice for someone to know:

If you are using .net Web Api 2 you could just do the following:

if (!ModelState.IsValid)
     return BadRequest(ModelState);

Depending on the model errors, you get this result:

{
   Message: "The request is invalid."
   ModelState: {
       model.PropertyA: [
            "The PropertyA field is required."
       ],
       model.PropertyB: [
             "The PropertyB field is required."
       ]
   }
}
