mysql -h "hostname" -u usr_name -pPASSWD "db_name" < sql_script_file

(use full path for sql_script_file if needed)

If you want to redirect the out put to a file

mysql -h "hostname" -u usr_name -pPASSWD "db_name" < sql_script_file > out_file

Here is a good example in Python3.

  >>> a = input("What is your name?")
  What is your name?Peter

  >>> b = input("Where are you from?")
  Where are you from?DE

  >>> print("So you are %s of %s" % (a, b))
  So you are Peter of DE

Try using Ctrl-click on the multiple places you want the cursors. Ctrl-D is for multiple incremental finds.

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

As explained in short C# (but also for other language compilers as well, like Java)

There is a predefined implicit conversion from short to int, long, float, double, or decimal.

You cannot implicitly convert nonliteral numeric types of larger storage size to short (see Integral Types Table for the storage sizes of integral types). Consider, for example, the following two short variables x and y:

short x = 5, y = 12;

The following assignment statement will produce a compilation error, because the arithmetic expression on the right-hand side of the assignment operator evaluates to int by default.

short z = x + y;   // Error: no conversion from int to short

To fix this problem, use a cast:

short z = (short)(x + y);   // OK: explicit conversion

It is possible though to use the following statements, where the destination variable has the same storage size or a larger storage size:

int m = x + y;
long n = x + y;

A good follow-up question is:

"why arithmetic expression on the right-hand side of the assignment operator evaluates to int by default" ?

A first answer can be found in:

Classifying and Formally Verifying Integer Constant Folding

The Java language specification defines exactly how integer numbers are represented and how integer arithmetic expressions are to be evaluated. This is an important property of Java as this programming language has been designed to be used in distributed applications on the Internet. A Java program is required to produce the same result independently of the target machine executing it.

In contrast, C (and the majority of widely-used imperative and object-oriented programming languages) is more sloppy and leaves many important characteristics open. The intention behind this inaccurate language specification is clear. The same C programs are supposed to run on a 16-bit, 32-bit, or even 64-bit architecture by instantiating the integer arithmetics of the source programs with the arithmetic operations built-in in the target processor. This leads to much more e?cient code because it can use the available machine operations directly. As long as the integer computations deal only with numbers being “sufficiently small”, no inconsistencies will arise.

In this sense, the C integer arithmetic is a placeholder which is not defined exactly by the programming language specification but is only completely instantiated by determining the target machine.

Java precisely defines how integers are represented and how integer arithmetic is to be computed.

      Java Integers
--------------------------
Signed         |  Unsigned
--------------------------
long  (64-bit) |
int   (32-bit) |
short (16-bit) |  char (16-bit)
byte  (8-bit)  |

Char is the only unsigned integer type. Its values represent Unicode characters, from \u0000 to \uffff, i.e. from 0 to 2¹⁶-1.

If an integer operator has an operand of type long, then the other operand is also converted to type long. Otherwise the operation is performed on operands of type int, if necessary shorter operands are converted into int. The conversion rules are exactly specified.

putting a quick example, should be a sufficient starting point

Code in Form A

public event EventHandler<EventArgs> RowAdded;

private void btnRowAdded_Click(object sender, EventArgs e)
{
     // insert data
     // if successful raise event
     OnRowAddedEvent();
}

private void OnRowAddedEvent()
{
     var listener = RowAdded;
     if (listener != null)
         listener(this, EventArgs.Empty);
}

Code in Form B

private void button1_Click(object sender, EventArgs e)
{
     var frm = new Form2();
     frm.RowAdded += new EventHandler<EventArgs>(frm_RowAdded);
     frm.Show();
}

void frm_RowAdded(object sender, EventArgs e)
{
     // retrieve data again
}

You can even consider creating your own EventArgs class that can contain the newly added data. You can then use this to directly add the data to a new row in DatagridView

Java arrays, like C++ arrays, have the fixed length that after initializing it, you cannot change it. But, like class template vector - vector <T> - in C++ you can use Java class ArrayList that has many more utilities than Java arrays have.

This worked for me.

$ echo 54657374696e672031203220330 | xxd -r -p
Testing 1 2 3$

-r tells it to convert hex to ascii as opposed to its normal mode of doing the opposite

-p tells it to use a plain format.

I just tried all of these, and for IE11, the only thing that seems to work is disabled="true". Values of disabled or no value given didnt work. As a matter of fact, the jsp got an error that equal is required for all fields, so I had to specify disabled="true" for this to work.

There are a lot of very good answers, but I just want to touch on one major difference between IE9 and IE < 9 when using event.button.

According to the old Microsoft specification for event.button the codes differ from the ones used by W3C. W3C considers only 3 cases:

1. Left mouse button is clicked - event.button === 1
2. Right mouse button is clicked - event.button === 3
3. Middle mouse button is clicked - event.button === 2

In older Internet Explorers however Microsoft are flipping a bit for the pressed button and there are 8 cases:

1. No button is clicked - event.button === 0 or 000
2. Left button is clicked - event.button === 1 or 001
3. Right button is clicked - event.button === 2 or 010
4. Left and right buttons are clicked - event.button === 3 or 011
5. Middle button is clicked - event.button === 4 or 100
6. Middle and left buttons are clicked - event.button === 5 or 101
7. Middle and right buttons are clicked - event.button === 6 or 110
8. All 3 buttons are clicked - event.button === 7 or 111

Despite the fact that this is theoretically how it should work, no Internet Explorer has ever supported the cases of two or three buttons simultaneously pressed. I am mentioning it because the W3C standard cannot even theoretically support this.

Basically the Kernel is the interface between hardware (devices which are available in Computer) and Application software is like MS Office, Visual Studio, etc.

If I answer "what is an OS?" then the answer could be the same. Hence the kernel is the part & core of the OS.

The very sensitive tasks of an OS like memory management, I/O management, process management are taken care of by the kernel only.

So the ultimate difference is:

1. Kernel is responsible for Hardware level interactions at some specific range. But the OS is like hardware level interaction with full scope of computer.
2. Kernel triggers SystemCalls to tell the OS that this resource is available at this point of time. The OS is responsible to handle those system calls in order to utilize the resource.

If a method doesn't return anything, it's either one of the following

• imperative - You're either asking the object to do something to itself.. e.g change state (without expecting any confirmation.. its assumed that it will be done)
• informational - just notifying someone that something happened (without expecting action or response) respectively.

Imperative methods - you can verify if the task was actually performed. Verify if state change actually took place. e.g.

void DeductFromBalance( dAmount ) 

can be tested by verifying if the balance post this message is indeed less than the initial value by dAmount

Informational methods - are rare as a member of the public interface of the object... hence not normally unit-tested. However if you must, You can verify if the handling to be done on a notification takes place. e.g.

void OnAccountDebit( dAmount )  // emails account holder with info

can be tested by verifying if the email is being sent

Post more details about your actual method and people will be able to answer better.
Update: Your method is doing 2 things. I'd actually split it into two methods that can now be independently tested.

string[] ExamineLogFileForX( string sFileName );
void InsertStringsIntoDatabase( string[] );

String[] can be easily verified by providing the first method with a dummy file and expected strings. The second one is slightly tricky.. you can either use a Mock (google or search stackoverflow on mocking frameworks) to mimic the DB or hit the actual DB and verify if the strings were inserted in the right location. Check this thread for some good books... I'd recomment Pragmatic Unit Testing if you're in a crunch.
In the code it would be used like

InsertStringsIntoDatabase( ExamineLogFileForX( "c:\OMG.log" ) );

The Heroku CLI has an easy shortcut for this. For an app named 'falling-wind-1624':

$ heroku git:remote -a falling-wind-1624
Git remote heroku added.

You can also use JSON.generate:

require 'json'

JSON.generate({ foo: "bar" })
=> "{\"foo\":\"bar\"}"

Or its alias, JSON.unparse:

require 'json'

JSON.unparse({ foo: "bar" })
=> "{\"foo\":\"bar\"}"

Setting a min-width on child elements will also create a breakpoint. For example breaking every 3 elements,

flex-grow: 1;
min-width: 33%; 

If there are 4 elements, this will have the 4th element wrap taking the full 100%. If there are 5 elements, the 4th and 5th elements will wrap and take each 50%.

Make sure to have parent element with,

flex-wrap: wrap

First, a short description of $on(), $broadcast() and $emit():

• .$on(name, listener) - Listens for a specific event by a given name
• .$broadcast(name, args) - Broadcast an event down through the $scope of all children
• .$emit(name, args) - Emit an event up the $scope hierarchy to all parents, including the $rootScope

Based on the following HTML (see full example here):

<div ng-controller="Controller1">
    <button ng-click="broadcast()">Broadcast 1</button>
    <button ng-click="emit()">Emit 1</button>
</div>

<div ng-controller="Controller2">
    <button ng-click="broadcast()">Broadcast 2</button>
    <button ng-click="emit()">Emit 2</button>
    <div ng-controller="Controller3">
        <button ng-click="broadcast()">Broadcast 3</button>
        <button ng-click="emit()">Emit 3</button>
        <br>
        <button ng-click="broadcastRoot()">Broadcast Root</button>
        <button ng-click="emitRoot()">Emit Root</button>
    </div>
</div>

The fired events will traverse the $scopes as follows:

• Broadcast 1 - Will only be seen by Controller 1 $scope
• Emit 1 - Will be seen by Controller 1 $scope then $rootScope
• Broadcast 2 - Will be seen by Controller 2 $scope then Controller 3 $scope
• Emit 2 - Will be seen by Controller 2 $scope then $rootScope
• Broadcast 3 - Will only be seen by Controller 3 $scope
• Emit 3 - Will be seen by Controller 3 $scope, Controller 2 $scope then $rootScope
• Broadcast Root - Will be seen by $rootScope and $scope of all the Controllers (1, 2 then 3)
• Emit Root - Will only be seen by $rootScope

JavaScript to trigger events (again, you can see a working example here):

app.controller('Controller1', ['$scope', '$rootScope', function($scope, $rootScope){
    $scope.broadcastAndEmit = function(){
        // This will be seen by Controller 1 $scope and all children $scopes 
        $scope.$broadcast('eventX', {data: '$scope.broadcast'});

        // Because this event is fired as an emit (goes up) on the $rootScope,
        // only the $rootScope will see it
        $rootScope.$emit('eventX', {data: '$rootScope.emit'});
    };
    $scope.emit = function(){
        // Controller 1 $scope, and all parent $scopes (including $rootScope) 
        // will see this event
        $scope.$emit('eventX', {data: '$scope.emit'});
    };

    $scope.$on('eventX', function(ev, args){
        console.log('eventX found on Controller1 $scope');
    });
    $rootScope.$on('eventX', function(ev, args){
        console.log('eventX found on $rootScope');
    });
}]);

The result of equals in your example is obviously false because you are comparing the map a with some values in it with an empty map b (probably a copy and paste error). I recommend to use proper variable names (so you can avoid these kinds of errors) and make use of generics, too.

    Map<String, String> first = new HashMap<String, String>();
    first.put("f"+"oo", "bar"+"bar");
    first.put("fo"+"o", "bar"+"bar");

    Map second = new HashMap();
    second.put("f"+"oo", "bar"+"bar");
    second.put("fo"+"o", "bar"+"bar");

    System.out.println("equals: " + first.equals(second));

The concatenation of your strings doesn't have any effect because it will be done at compile time.

Use std::equal algorithm from <algorithms> with reverse iteration:

std::string LogExt = ".log";
if (std::equal(LogExt.rbegin(), LogExt.rend(), filename.rbegin())) {
   …
}

You can use ng-repeat with option like this:

<form>
    <select ng-model="yourSelect" 
        ng-options="option as option for option in ['var1', 'var2', 'var3']"
        ng-init="yourSelect='var1'"></select>
    <input type="hidden" name="yourSelect" value="{{yourSelect}}" />
</form>

When you submit your form you can get value of input hidden.

ng-selected ng-repeat

What type of variable is format?

From a java POV, format is an implemtation of an anonymous interface. This interface has one method named for each mime type. When you invoke one of those methods (passing it a block), then if rails feels that the user wants that content type, then it will invoke your block.

The twist, of course, is that this anonymous glue object doesn't actually implement an interface - it catches the method calls dynamically and works out if its the name of a mime type that it knows about.

Personally, I think it looks weird: the block that you pass in is executed. It would make more sense to me to pass in a hash of format labels and blocks. But - that's how its done in RoR, it seems.

Start your IDE with administrative privilege( Windows: right click and run as admin), so that it has read write access to tomact folder for deployment. It worked for me.

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

I do not think that you can do this easily. you should consider this answer here:

How can I display a pdf document into a Webview?

basically you'll be able to see a pdf if it is hosted online via google documents, but not if you have it in your device (you'll need a standalone reader for that)

I'm trying this before

cd /opt/lampp/phpmyadmin

Then

gedit config.inc.php

Find this

$cfg['Servers'][$i]['host'] = 

If there is localhost change it to 127.0.0.1

Note : if there is '//' remove // before $cfg['Servers'][$i]['host']

I checked again http://localhost/phpmyadmin/

Mysqli said:

"phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server."

I'm opening again config.inc.php and I found

$cfg['Servers'][$i]['password'] =

Fill the password with your password

It worked for me. It may work for you too.

From executing the first query (by passing source DB and table name) you will get a pre-created execution query for the second SP, all you have to do is define is the column from your source: + Stable + Value (will be used to concentrate values based on that) + Dim (column you want to use to pivot by)

Names and datatypes will be defined automatically!

I cant recommend it for any production environments but does the job for adhoc BI requests.

you have an type error in example of code. You forget curlybracket after success

$.ajax({
 type: "POST",
 url: '@Url.Action("Search","Controller")',
 data: "{queryString:'" + searchVal + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "html",
 success: function (data) {
     alert("here" + data.d.toString());
 }
})

;

Change the 5 to 5.0. You're getting integer division.

While the accepted answer is correct, I'll add a more elegant version (in my opinion):

boolean idExists = tabPane.getTabs().stream()
    .map(Tab::getId)
    .anyMatch(idToCheck::equals);

Don't neglect using Stream#map() which allows to flatten the data structure before applying the Predicate.

If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:

next(obj for obj in objs if obj.val == 5)

This is however faster than a complete list comprehension. Compare these two:

[i for i in xrange(100000) if i == 1000][0]

next(i for i in xrange(100000) if i == 1000)

The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).

In addition to Varun Achar's answer, this is the Java 8 variant I came up with, that uses java.time.LocalDate and ZonedDateTime instead of the old java.util.Date classes.

public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {

    @Override
    public LocalDate deserialize(JsonParser jsonparser, DeserializationContext deserializationcontext) throws IOException {

        String string = jsonparser.getText();

        if(string.length() > 20) {
            ZonedDateTime zonedDateTime = ZonedDateTime.parse(string);
            return zonedDateTime.toLocalDate();
        }

        return LocalDate.parse(string);
    }
  }

This has been so frustrating, My problem was that within a newly constructed conda python36 environment, jupyter refused to load “seaborn” - even though seaborn was installed within that environment. It seemed to be able to import plenty of other files from the same environment — for example numpy and pandas but just not seaborn. I tried many of the fixes suggested here and on other threads without success. Until I realised that Jupyter was not running kernel python from within that environment but running the system python as kernel. Even though a decent looking kernel and kernel.json were already present in the environment. It was only after reading this part of the ipython documentation: https://ipython.readthedocs.io/en/latest/install/kernel_install.html#kernels-for-different-environments and using these commands:

source activate other-env
python -m ipykernel install --user --name other-env --display-name "Python (other-env)"

I was able to get everything going nicely. (I didn’t actually use the —user variable).

One thing I have not yet figured is how to set the default python to be the "Python (other-env)" one. At present an existing .ipynb file opened from the Home screen will use the system python. I have to use the Kernel menu “Change kernel” to select the environment python.

This answer is based on this excellent answer by 18446744073709551615. Their solution, though helpful, does not size the image icon with the surrounding text. It also doesn't set the icon colour to that of the surrounding text.

The solution below takes a white, square icon and makes it fit the size and colour of the surrounding text.

    }

        final Spannable spannable = Spannable.Factory.getInstance().newSpannable(text);
        addImages(context, spannable, lineHeight, colour);
        return spannable;
    }

        while (matcher.find()) {
            boolean set = true;
            for (ImageSpan span : spannable.getSpans(matcher.start(), matcher.end(), ImageSpan.class)) {
                if (spannable.getSpanStart(span) >= matcher.start()
                        && spannable.getSpanEnd(span) <= matcher.end()) {
                    spannable.removeSpan(span);
                } else {
                    set = false;
                    break;
                }
            }
            final String resName = spannable.subSequence(matcher.start(1), matcher.end(1)).toString().trim();
            final int id = context.getResources().getIdentifier(resName, DRAWABLE, context.getPackageName());
            if (set) {
                hasChanges = true;
                spannable.setSpan(makeImageSpan(context, id, lineHeight, colour),
                        matcher.start(),
                        matcher.end(),
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE

    private static ImageSpan makeImageSpan(Context context, int drawableResId, int size, int colour) {
        final Drawable drawable = context.getResources().getDrawable(drawableResId);
        drawable.mutate();

        drawable.setBounds(0, 0, size, size);
        return new ImageSpan(drawable, ImageSpan.ALIGN_BOTTOM);
    }

}

How to use:

Simply embed references to the desired icons in the text. It doesn't matter whether the text is set programatically through textView.setText(R.string.string_resource); or if it's set in xml.

To embed a drawable icon named example.png, include the following string in the text: [img src=example/].

For example, a string resource might look like this:

<string name="string_resource">This [img src=example/] is an icon.</string>

This style is also possible:

$.get("mypage.html")
    .done(function(result){
        alert("done. read "+result.length+" characters.");
    })
    .fail(function(jqXHR, textStatus, errorThrown){
        alert("fail. status: "+textStatus);
    })

var pixelFromTop = 500;     
$('html, body').animate({ scrollTop: pixelFromTop  }, 1);

So when page open it is automatically scroll down after 1 milisecond

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

To add spacing between entries in a legend, adjust the margins of the theme element legend.text.

To add 30pt of space to the right of each legend label (may be useful for a horizontal legend):

p + theme(legend.text = element_text(
    margin = margin(r = 30, unit = "pt")))

To add 30pt of space to the left of each legend label (may be useful for a vertical legend):

p + theme(legend.text = element_text(
    margin = margin(l = 30, unit = "pt")))

for a ggplot2 object p. The keywords are legend.text and margin.

[Note about edit: When this answer was first posted, there was a bug. The bug has now been fixed]

The original question asked for the exponent and mantissa, rather than the fractional and whole part.

To get the exponent and mantissa from a double you can convert it into the IEEE 754 representation and extract the bits like this:

long bits = Double.doubleToLongBits(3.25);

boolean isNegative = (bits & 0x8000000000000000L) != 0; 
long exponent      = (bits & 0x7ff0000000000000L) >> 52;
long mantissa      =  bits & 0x000fffffffffffffL;

I asked a similar question. Based on @sawa's answer, the most succinct way to represent an integer in a string in binary format is to use the string formatter:

"%b" % 245
=> "11110101"

You can also choose how long the string representation to be, which might be useful if you want to compare fixed-width binary numbers:

1.upto(10).each { |n| puts "%04b" % n }
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010

If you have an ES2015 environment (as of this writing: io.js, IE11, Chrome, Firefox, WebKit nightly), then the following will work, and will be fast (viz. O(n)):

function hasDuplicates(array) {
    return (new Set(array)).size !== array.length;
}

If you only need string values in the array, the following will work:

function hasDuplicates(array) {
    var valuesSoFar = Object.create(null);
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (value in valuesSoFar) {
            return true;
        }
        valuesSoFar[value] = true;
    }
    return false;
}

We use a "hash table" valuesSoFar whose keys are the values we've seen in the array so far. We do a lookup using in to see if that value has been spotted already; if so, we bail out of the loop and return true.

If you need a function that works for more than just string values, the following will work, but isn't as performant; it's O(n²) instead of O(n).

function hasDuplicates(array) {
    var valuesSoFar = [];
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (valuesSoFar.indexOf(value) !== -1) {
            return true;
        }
        valuesSoFar.push(value);
    }
    return false;
}

The difference is simply that we use an array instead of a hash table for valuesSoFar, since JavaScript "hash tables" (i.e. objects) only have string keys. This means we lose the O(1) lookup time of in, instead getting an O(n) lookup time of indexOf.

31-DEC-95 isn't a string, nor is 20-JUN-94. They're numbers with some extra stuff added on the end. This should be '31-DEC-95' or '20-JUN-94' - note the single quote, '. This will enable you to do a string comparison.

However, you're not doing a string comparison; you're doing a date comparison. You should transform your string into a date. Either by using the built-in TO_DATE() function, or a date literal.

TO_DATE()

select employee_id
  from employee
 where employee_date_hired > to_date('31-DEC-95','DD-MON-YY')

This method has a few unnecessary pitfalls

• As a_horse_with_no_name noted in the comments, DEC, doesn't necessarily mean December. It depends on your NLS_DATE_LANGUAGE and NLS_DATE_FORMAT settings. To ensure that your comparison with work in any locale you can use the datetime format model MM instead
• The year '95 is inexact. You know you mean 1995, but what if it was '50, is that 1950 or 2050? It's always best to be explicit

select employee_id
  from employee
 where employee_date_hired > to_date('31-12-1995','DD-MM-YYYY')

Date literals

A date literal is part of the ANSI standard, which means you don't have to use an Oracle specific function. When using a literal you must specify your date in the format YYYY-MM-DD and you cannot include a time element.

select employee_id
  from employee
 where employee_date_hired > date '1995-12-31'

Remember that the Oracle date datatype includes a time elemement, so the date without a time portion is equivalent to 1995-12-31 00:00:00.

If you want to include a time portion then you'd have to use a timestamp literal, which takes the format YYYY-MM-DD HH24:MI:SS[.FF0-9]

select employee_id
  from employee
 where employee_date_hired > timestamp '1995-12-31 12:31:02'

Further information

NLS_DATE_LANGUAGE is derived from NLS_LANGUAGE and NLS_DATE_FORMAT is derived from NLS_TERRITORY. These are set when you initially created the database but they can be altered by changing your inialization parameters file - only if really required - or at the session level by using the ALTER SESSION syntax. For instance:

alter session set nls_date_format = 'DD.MM.YYYY HH24:MI:SS';

This means:

• DD numeric day of the month, 1 - 31
• MM numeric month of the year, 01 - 12 ( January is 01 )
• YYYY 4 digit year - in my opinion this is always better than a 2 digit year YY as there is no confusion with what century you're referring to.
• HH24 hour of the day, 0 - 23
• MI minute of the hour, 0 - 59
• SS second of the minute, 0-59

You can find out your current language and date language settings by querying V$NLS_PARAMETERSs and the full gamut of valid values by querying V$NLS_VALID_VALUES.

• Format models

Incidentally, if you want the count(*) you need to group by employee_id

select employee_id, count(*)
  from employee
 where employee_date_hired > date '1995-12-31'
 group by employee_id

This gives you the count per employee_id.

I posted another solution here Which is the best approach to insert an vector (svg) graph into a react native application, This approach use a vector font(from svg) instead a svg file. PS: Its works great in ios and android, and you also can change the color and size of your vector icon.

If you want to insert a svg directly into your app, you can try a 3rd party library : react-native-svg. With more than 3k stars in github it's one of the best approach.

• install:
  • npm i react-native-svg
  • npm i react-native-svg-uri
• link the to native:
  • react-native link react-native-svg

And here's a sample:

import * as React from 'react';
import SvgUri from 'react-native-svg-uri';
import testSvg from './test.svg';
export default () => (
  <SvgUri
    width="200"
    height="200"
    svgXmlData={testSvg}
  />
);

Convert an integer directly to long by adding 'L' to the end of Integer.

Long i = 1234L;

sentence.sub! 'Robert', 'Joe'

Won't cause an exception if the replaced word isn't in the sentence (the []= variant will).

How to replace all instances?

The above replaces only the first instance of "Robert".

To replace all instances use gsub/gsub! (ie. "global substitution"):

sentence.gsub! 'Robert', 'Joe'

The above will replace all instances of Robert with Joe.

A simple BFS and DFS recursion in Java:
Just push/offer the root node of the tree in the stack/queue and call these functions.

public static void breadthFirstSearch(Queue queue) {

    if (queue.isEmpty())
        return;

    Node node = (Node) queue.poll();

    System.out.println(node + " ");

    if (node.right != null)
        queue.offer(node.right);

    if (node.left != null)
        queue.offer(node.left);

    breadthFirstSearch(queue);
}

public static void depthFirstSearch(Stack stack) {

    if (stack.isEmpty())
        return;

    Node node = (Node) stack.pop();

    System.out.println(node + " ");

    if (node.right != null)
        stack.push(node.right);

    if (node.left != null)
        stack.push(node.left);

    depthFirstSearch(stack);
}

Google Places API also provides REST api including Places Autocomplete. https://developers.google.com/places/documentation/autocomplete

But the data retrieve from the service must use for a map.

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

array_map and trim can do the job

$trimmed_array = array_map('trim', $fruit);
print_r($trimmed_array);

In a fresh spreadsheet (US locale) with 12/19/11 in A1 and DT 30 in B1 then:

=A1+right(B1,2)

in say C1 returns 1/18/12.

As a string function RIGHT returns Text but that can be coerced into a number when adding. In adding a number to dates unity is treated as one day. Within (very wide) limits, months and even years are adjusted automatically.

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

Consider the following code

    int a[10];
    a[0] = 0;
    a[1] = 0;
    a[2] = 0;
    a[3] = 0;
    int i = 0;
    a[i++] = i++;
    a[i++] = i++;
    a[i++] = i++;

since i++ gets evaluated twice the output is (from vs2005 debugger)

    [0] 0   int
    [1] 0   int
    [2] 2   int
    [3] 0   int
    [4] 4   int

Now consider the following code :

    int a[10];
    a[0] = 0;
    a[1] = 0;
    a[2] = 0;
    a[3] = 0;
    int i = 0;
    a[++i] = ++i;
    a[++i] = ++i;
    a[++i] = ++i;

Notice that the output is the same. Now you might think that ++i and i++ are the same. They are not

    [0] 0   int
    [1] 0   int
    [2] 2   int
    [3] 0   int
    [4] 4   int

Finally consider this code

    int a[10];
    a[0] = 0;
    a[1] = 0;
    a[2] = 0;
    a[3] = 0;
    int i = 0;
    a[++i] = i++;
    a[++i] = i++;
    a[++i] = i++;

The output is now :

    [0] 0   int
    [1] 1   int
    [2] 0   int
    [3] 3   int
    [4] 0   int
    [5] 5   int

So they are not the same, mixing both result in not so intuitive behavior. I think that for loops are ok with ++, but watch out when you have multiple ++ symbols on the same line or same instruction

using indices, for loops and formatting:

import numpy as np

def printMatrix(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print "%6.f" %a[i,j],
      print
   print      


def printMatrixE(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print("%6.3f" %a[i,j]),
      print
   print      


inf = float('inf')
A = np.array( [[0,1.,4.,inf,3],
     [1,0,2,inf,4],
     [4,2,0,1,5],
     [inf,inf,1,0,3],
     [3,4,5,3,0]])

printMatrix(A)    
printMatrixE(A)    

which yields the output:

Matrix[5][5]
     0      1      4    inf      3
     1      0      2    inf      4
     4      2      0      1      5
   inf    inf      1      0      3
     3      4      5      3      0

Matrix[5][5]
 0.000  1.000  4.000    inf  3.000
 1.000  0.000  2.000    inf  4.000
 4.000  2.000  0.000  1.000  5.000
   inf    inf  1.000  0.000  3.000
 3.000  4.000  5.000  3.000  0.000

Thiago answer is correct, adding sample more specific to question, @ElementCollection will create new table in your database, but without mapping two tables, It means that the collection is not a collection of entities, but a collection of simple types (Strings, etc.) or a collection of embeddable elements (class annotated with @Embeddable).

Here is the sample to persist list of String

@ElementCollection
private Collection<String> options = new ArrayList<String>();

Here is the sample to persist list of Custom object

@Embedded
@ElementCollection
private Collection<Car> carList = new ArrayList<Car>();

For this case we need to make class Embeddable

@Embeddable
public class Car {
}

class DayOfWeek {
    static $values = array(
        self::MONDAY,
        self::TUESDAY,
        // ...
    );

    const MONDAY  = 0;
    const TUESDAY = 1;
    // ...
}

$today = DayOfWeek::MONDAY;

// If you want to check if a value is valid
assert( in_array( $today, DayOfWeek::$values ) );

Don't use reflection. It makes it extremely difficult to reason about your code and track down where something is being used, and tends to break static analysis tools (eg what's built into your IDE).

Get number of threads using jstack

jstack <PID> | grep 'java.lang.Thread.State' | wc -l

The result of the above code is quite different from top -H -p <PID> or ps -o nlwp <PID> because jstack gets only threads from created by the application.

In other words, jstack will not get GC threads

There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:

cat /proc/cpuinfo

Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.

The model fields contained by _meta are listed in multiple locations as lists of the respective field objects. It may be easier to work with them as a dictionary where the keys are the field names.

In my opinion, this is most irredundant and expressive way to collect and organize the model field objects:

def get_model_fields(model):
  fields = {}
  options = model._meta
  for field in sorted(options.concrete_fields + options.many_to_many + options.virtual_fields):
    fields[field.name] = field
  return fields

(See This example usage in django.forms.models.fields_for_model.)

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

I make an alternative that the user don’t need to know the values, the system get and use variables to update.

The universal tool for string formatting, sprintf:

$stamp = sprintf('%s%02s', $year, $month);

http://php.net/manual/en/function.sprintf.php

This makes callbacks sound like return statements at the end of methods.

I'm not sure that's what they are.

I think Callbacks are actually a call to a function, as a consequence of another function being invoked and completing.

I also think Callbacks are meant to address the originating invocation, in a kind of "hey! that thing you asked for? I've done it - just thought I would let you know - back over to you".

I made a custom button class to achieve this.

CustomButton.java

public class CustomButton extends android.support.v7.widget.AppCompatButton {

    private Drawable mDrawable;

    public CustomButton(Context context, AttributeSet attrs) {
        super(context, attrs);

        TypedArray a = context.getTheme().obtainStyledAttributes(
                attrs,
                R.styleable.CustomButton,
                0, 0);

        try {
            float mWidth = a.getDimension(R.styleable.CustomButton_drawable_width, 0);
            float mHeight = a.getDimension(R.styleable.CustomButton_drawable_width, 0);

            Drawable[] drawables = this.getCompoundDrawables();
            Drawable[] resizedDrawable = new Drawable[4];

            for (int i = 0; i < drawables.length; i++) {
                if (drawables[i] != null) {
                    mDrawable = drawables[i];
                }
                resizedDrawable[i] = getResizedDrawable(drawables[i], mWidth, mHeight);
            }

            this.setCompoundDrawables(resizedDrawable[0], resizedDrawable[1], resizedDrawable[2], resizedDrawable[3]);
        } finally {
            a.recycle();
        }
    }

    public Drawable getmDrawable() {
        return mDrawable;
    }

    private Drawable getResizedDrawable(Drawable drawable, float mWidth, float mHeight) {
        if (drawable == null) {
            return null;
        }

        try {
            Bitmap bitmap;

            bitmap = Bitmap.createBitmap((int)mWidth, (int)mHeight, Bitmap.Config.ARGB_8888);

            Canvas canvas = new Canvas(bitmap);
            drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
            drawable.draw(canvas);
            return drawable;
        } catch (OutOfMemoryError e) {
            // Handle the error
            return null;
        }
    }
}

How much shorter do you want it to be? It is only an extra 2 lines AND it is clear and concise logic.

I think the more important thing you need to decide is if null is a valid value or not. If they are not valid, you should write you code to prevent it from happening. Then you would not need this kind of check. If you go get an exception while doing a foreach loop, that is a sign that there is a bug somewhere else in your code.

You can resolve the issue by forcing the collation used in a query to be a particular collation, e.g. SQL_Latin1_General_CP1_CI_AS or DATABASE_DEFAULT. For example:

SELECT MyColumn
FROM FirstTable a
INNER JOIN SecondTable b
ON a.MyID COLLATE SQL_Latin1_General_CP1_CI_AS = 
b.YourID COLLATE SQL_Latin1_General_CP1_CI_AS

In the above query, a.MyID and b.YourID would be columns with a text-based data type. Using COLLATE will force the query to ignore the default collation on the database and instead use the provided collation, in this case SQL_Latin1_General_CP1_CI_AS.

Basically what's going on here is that each database has its own collation which "provides sorting rules, case, and accent sensitivity properties for your data" (from http://technet.microsoft.com/en-us/library/ms143726.aspx) and applies to columns with textual data types, e.g. VARCHAR, CHAR, NVARCHAR, etc. When two databases have differing collations, you cannot compare text columns with an operator like equals (=) without addressing the conflict between the two disparate collations.

So you want the next multiple of 6, is that it?

You can divide your number by 6, then ceil it, and multiply it again:

$answer = ceil($foo / 6) * 6;

Using an absolute or relative string as the filename.

name_of_file = input("What is the name of the file: ")
completeName = '/home/user/Documents'+ name_of_file + ".txt"
file1 = open(completeName , "w")
toFile = input("Write what you want into the field")
file1.write(toFile)
file1.close()

This supplemental answer shows the effect of changing the line spacing.

You can set the multiplier and/or extra spacing with

textView.setLineSpacing(float add, float mult)

Or you can get the values with

int lineHeight = textView.getLineHeight();
float add = tvSampleText.getLineSpacingExtra();          // API 16+
float mult = tvSampleText.getLineSpacingMultiplier();    // API 16+

where the formula is

lineHeight = fontMetricsLineHeight * mult + add

The default multiplier is 1 and the default extra spacing is 0.

I also faced the same problem and the problem was that the libraries were missing in some of the following files.

settings.gradle, app/build.gradle, package.json, MainApplication.java

Suppose the library is react-native-vector-icons then it should be mentioned in following files;

In app/build.gradle file under dependencies section add:

compile project(':react-native-vector-icons')

In settings.gradle file under android folder, add the following:

include ':react-native-vector-icons' project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')

In MainApplication.java, add the following:

Import the dependency: import com.oblador.vectoricons.VectorIconsPackage;

and then add: new VectorIconsPackage() in getPackages() method.

To create and save an object in a single step, use the create() method.

Without the need to install the grep variant pcregrep, you can do multiline search with grep.

$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c

Explanation:

-P activate perl-regexp for grep (a powerful extension of regular expressions)

-z suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.

-o print only matching. Because we're using -z, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.

In regexp:

(?s) activate PCRE_DOTALL, which means that . finds any character or newline

\N find anything except newline, even with PCRE_DOTALL activated

.*? find . in non-greedy mode, that is, stops as soon as possible.

^ find start of line

\1 backreference to the first group (\s*). This is a try to find the same indentation of method.

As you can imagine, this search prints the main method in a C (*.c) source file.

import pkg_resources
packages = [dist.project_name for dist in pkg_resources.working_set]
try:
   for count, item in enumerate(packages):
      print(item, pkg_resources.get_distribution(item).version)
except:
    pass here

The indentations might not be perfect. The reason I am using a Try- Except block is that few library names will throw errors because of parsing the library names to process the versions. even though packages variable will contain all the libraries install in your environment.

Anonymous classes must extend or implement something, like any other Java class, even if it's just java.lang.Object.

For example:

Runnable r = new Runnable() {
   public void run() { ... }
};

Here, r is an object of an anonymous class which implements Runnable.

An anonymous class can extend another class using the same syntax:

SomeClass x = new SomeClass() {
   ...
};

What you can't do is implement more than one interface. You need a named class to do that. Neither an anonymous inner class, nor a named class, however, can extend more than one class.

Another modification:

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

The difference with this is that it waits 10 seconds AFTER the ajax call is one. So really the time between refreshes is 10 seconds + length of ajax call. The benefit of this is if your server takes longer than 10 seconds to respond, you don't get two (and eventually, many) simultaneous AJAX calls happening.

Also, if the server fails to respond, it won't keep trying.

I've used a similar method in the past using .ajax to handle even more complex behaviour:

function update() {
  $("#notice_div").html('Loading..'); 
  $.ajax({
    type: 'GET',
    url: 'response.php',
    timeout: 2000,
    success: function(data) {
      $("#some_div").html(data);
      $("#notice_div").html(''); 
      window.setTimeout(update, 10000);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      $("#notice_div").html('Timeout contacting server..');
      window.setTimeout(update, 60000);
    }
}

This shows a loading message while loading (put an animated gif in there for typical "web 2.0" style). If the server times out (in this case takes longer than 2s) or any other kind of error happens, it shows an error, and it waits for 60 seconds before contacting the server again.

This can be especially beneficial when doing fast updates with a larger number of users, where you don't want everyone to suddenly cripple a lagging server with requests that are all just timing out anyways.

I've also found this error can be caused when writing json_encoded() data to MySQL. To get around it I base64_encode() the JSON. Please not that when decoded, the JSON encoding can change values. Nb. 24 can become 24.00

Since this is the first Stackoverflow question that appears on Google when searching for Error: $injector:unpr Unknown Provider I'll add this here.

Make sure that in your index.html any modules/dependencies are not being loaded after they are needed.

For example in my code customFactory.factory.js begins like this:

angular
   .module("app.module1")
   .factory("customFactory", customFactory);

However the index.html looked like this:

    <script src="/src/client/app/customFactory.factory.js"></script>
    <script src="/src/client/app/module1.module.js"></script>

Where it should've really looked like this:

    <script src="/src/client/app/module1.module.js"></script>
    <script src="/src/client/app/customFactory.factory.js"></script>

Since customFactory.factory.js is declared as part of module1, it needs to be loaded before customFactory

Try this: (source: http://just-another-blog.net/programming/powershell-and-the-net-framework/)

Add-Type -AssemblyName System.Windows.Forms 

$position = [System.Windows.Forms.Cursor]::Position  
$position.X++  
[System.Windows.Forms.Cursor]::Position = $position 

    while(1) {  
    $position = [System.Windows.Forms.Cursor]::Position  
    $position.X++  
    [System.Windows.Forms.Cursor]::Position = $position  

    $time = Get-Date;  
    $shorterTimeString = $time.ToString("HH:mm:ss");  

    Write-Host $shorterTimeString "Mouse pointer has been moved 1 pixel to the right"  
    #Set your duration between each mouse move
    Start-Sleep -Seconds 150  
    }  

Try :

Msg * "insert your message here" 

If you are using Windows XP's command.com, this will open a message box.

Opening a new cmd window isn't quite what you were asking for, I gather. You could also use VBScript, and use this with your .bat file. You would open it from the bat file with this command:

cd C:\"location of vbscript"

What this does is change the directory command.com will search for files from, then on the next line:

"insert name of your vbscript here".vbs

Then you create a new Notepad document, type in

<script type="text/vbscript">
    MsgBox "your text here"
</script>

You would then save this as a .vbs file (by putting ".vbs" at the end of the filename), save as "All Files" in the drop down box below the file name (so it doesn't save as .txt), then click Save!

range creates a list, so if you do range(1, 10000000) it creates a list in memory with 10000000 elements. xrange is a generator, so it evaluates lazily.

This brings you two advantages:

1. You can iterate longer lists without getting a MemoryError.
2. As it resolves each number lazily, if you stop iteration early, you won't waste time creating the whole list.

one of the simplest, fastest, more reusable and flexible is:

Array.prototype.sum = function () {
    for(var total = 0,l=this.length;l--;total+=this[l]); return total;
}

// usage
var array = [1,2,3,4,5,6,7,8,9,10];
array.sum()

It's a limitation of hive.

1.You cannot update data after it is inserted

2.There is no "insert into table values ... " statement

3.You can only load data using bulk load

4.There is not "delete from " command

5.You can only do bulk delete

But you still want to insert record from hive console than you can do select from statck. refer this

You can use UNION ALL instead.

SELECT mt.ID, mt.ParentID, ot.MasterID FROM dbo.MainTable AS mt Union ALL SELECT mt.ID, mt.ParentID, ot.MasterID FROM dbo.OtherTable AS ot

User creation with password for a specific database to secure database access :

use dbName

db.createUser(
   {
     user: "dbUser",
     pwd: "dbPassword",
     roles: [ "readWrite", "dbAdmin" ]
   }
)

I moved configuration to code to enable easy modification from CI using system variable. I used this code for file name and result is 'Log_03-23-2020.log'

            log4net.Repository.ILoggerRepository repository = LogManager.GetRepository(Assembly.GetEntryAssembly());
            Hierarchy hierarchy = (Hierarchy)repository;
            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = "%date %level - %message%newline%exception";
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = true;
            roller.File = "Log_";
            roller.DatePattern = "MM-dd-yyyy'.log'";
            roller.Layout = patternLayout;
            roller.MaxFileSize = 1024*1024*10;
            roller.MaxSizeRollBackups = 10;
            roller.StaticLogFileName = false;
            roller.RollingStyle = RollingFileAppender.RollingMode.Composite;
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

first use this:

LayoutInflater inflater = (LayoutInflater) Read_file.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Read file is current activity in which you want your context.

View layout = inflater.inflate(R.layout.your_layout_name,(ViewGroup)findViewById(R.id.layout_name_id));

then you can use this to find any element in layout.

ImageView myImage = (ImageView) layout.findViewById(R.id.my_image);

By default, IUSR account is used for anonymous user.

All you need to do is:

IIS -> Authentication --> Set Anonymous Authentication to Application Pool Identity.

Problem solved :)

In Angular2+ for anyone interested:

<input type="text" placeholder="My Date" [ngModel]="myDate | date: 'longDate'">

with type of filters in DatePipe Angular.

As it's 2019 I'd like to give an updated answer to this question. It is possible to achieve the same result as nested forms, but without nesting them. HTML5 introduced the form attribute. You can add the form attribute to form controls outside of a form to link them to a specific form element (by id).

https://www.impressivewebs.com/html5-form-attribute/

This way you can structure your html like this:

<form id="main-form" action="/main-action" method="post"></form>
<form id="sub-form"  action="/sub-action"  method="post"></form>

<div class="main-component">
    <input type="text" name="main-property1" form="main-form" />
    <input type="text" name="main-property2" form="main-form" />

    <div class="sub-component">
        <input type="text" name="sub-property1" form="sub-form" />
        <input type="text" name="sub-property2" form="sub-form" />
        <input type="submit" name="sub-save" value="Save" form="sub-form" />
    </div>

    <input type="submit" name="main-save" value="Save" form="main-form" />
</div>

The form attribute is supported by all modern browsers. IE does not support this though but IE is not a browser anymore, rather a compatibility tool, as confirmed by Microsoft itself: https://www.zdnet.com/article/microsoft-security-chief-ie-is-not-a-browser-so-stop-using-it-as-your-default/. It's about time we stop caring about making things work in IE.

https://caniuse.com/#feat=form-attribute
https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#attr-fae-form

From the html spec:

This feature allows authors to work around the lack of support for nested form elements.

Slicing a list

top5 = array[:5]

• To slice a list, there's a simple syntax: array[start:stop:step]
• You can omit any parameter. These are all valid: array[start:], array[:stop], array[::step]

Slicing a generator

 import itertools
 top5 = itertools.islice(my_list, 5) # grab the first five elements

• You can't slice a generator directly in Python. itertools.islice() will wrap an object in a new slicing generator using the syntax itertools.islice(generator, start, stop, step)

• Remember, slicing a generator will exhaust it partially. If you want to keep the entire generator intact, perhaps turn it into a tuple or list first, like: result = tuple(generator)

This for me is the best way SWIFT

        let myString = "  ciao   \n              ciao     "
        var finalString = myString as NSString

        for character in myString{
        if character == " "{

            finalString = finalString.stringByReplacingOccurrencesOfString(" ", withString: "")

        }else{
            finalString = finalString.stringByReplacingOccurrencesOfString("\n", withString: "")

        }

    }
     println(finalString)

and the result is : ciaociao

But the trick is this!

 extension String {

    var NoWhiteSpace : String {

    var miaStringa = self as NSString

    if miaStringa.containsString(" "){

      miaStringa =  miaStringa.stringByReplacingOccurrencesOfString(" ", withString: "")
    }
        return miaStringa as String

    }
}

let myString = "Ciao   Ciao       Ciao".NoWhiteSpace  //CiaoCiaoCiao

I personally prefer to use the other approach, when you have 2 different classes. So you don't need any static class. This is basically to avoid write Class.Builder when you has to create a new instance.

public class Person {
    private String attr1;
    private String attr2;
    private String attr3;

    // package access
    Person(PersonBuilder builder) {
        this.attr1 = builder.getAttr1();
        // ...
    }

    // ...
    // getters and setters 
}

public class PersonBuilder (
    private String attr1;
    private String attr2;
    private String attr3;

    // constructor with required attribute
    public PersonBuilder(String attr1) {
        this.attr1 = attr1;
    }

    public PersonBuilder setAttr2(String attr2) {
        this.attr2 = attr2;
        return this;
    }

    public PersonBuilder setAttr3(String attr3) {
        this.attr3 = attr3;
        return this;
    }

    public Person build() {
        return new Person(this);
    }
    // ....
}

So, you can use your builder like this:

Person person = new PersonBuilder("attr1")
                            .setAttr2("attr2")
                            .build();

I was facing a similar problem. The solution that I found out was :

1. Declare an interface in your DialogFragment just like James McCracken has explained above.

2. Implement the interface in your activity (not fragment! That is not a good practice).

3. From the callback method in your activity, call a required public function in your fragment which does the job that you want to do.

Thus, it becomes a two-step process : DialogFragment -> Activity and then Activity -> Fragment

You can use both .content and .container to overflow:auto. Means if it's text is exceed automatically scroll will come x-axis and y-axis. (no need to give separete x-axis and y-axis commonly give overflow:auto)

.content {overflow:auto;}

It looks like you're running this on Windows (given your H://log.txt file path).

Try using \r\n instead of just \n.

Honestly, \n is fine; you're probably viewing the log file in notepad or something else that doesn't render non-Windows newlines. Try opening it in a different viewer/editor (e.g. Wordpad).

urllib went through some changes in Python3 and can now be imported from the parse submodule

>>> from urllib.parse import quote  
>>> quote('"')                      
'%22'                               

You can convert a number to a string with n decimal places using the SPRINTF command:

>> x = 1.23;
>> sprintf('%0.6f', x)

ans =

1.230000

>> x = 1.23456789;
>> sprintf('%0.6f', x)

ans =

1.234568

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

For those of you who would rather not go with Regex and are on the .NET 2.0 Framework (AKA no LINQ):

Only Letters:

public static bool IsAllLetters(string s)
{
    foreach (char c in s)
    {
        if (!Char.IsLetter(c))
            return false;
    }
    return true;
}

Only Numbers:

    public static bool IsAllDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters:

    public static bool IsAllLettersOrDigits(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c))
                return false;
        }
        return true;
    }

Only Numbers Or Letters Or Underscores:

    public static bool IsAllLettersOrDigitsOrUnderscores(string s)
    {
        foreach (char c in s)
        {
            if (!Char.IsLetterOrDigit(c) && c != '_')
                return false;
        }
        return true;
    }

Specify title to each ViewController and then get the title of current ViewController by the code given below.

-(void)viewDidUnload {
  NSString *currentController = self.navigationController.visibleViewController.title;

Then check it by your title like this

  if([currentController isEqualToString:@"myViewControllerTitle"]){
    //write your code according to View controller.
  }
}

Use that Code

 $('#button').submit(function(e) {
    e.preventDefault();
    // Coding
    $('#IDModal').modal('toggle'); //or  $('#IDModal').modal('hide');
    return false;
});

The explanation below from the official documentation helped me understand kubectl apply.

This command will compare the version of the configuration that you’re pushing with the previous version and apply the changes you’ve made, without overwriting any automated changes to properties you haven’t specified.

kubectl create on the other hand will create (should be non-existing) resources.

Find a complete working example below:

The code by @Android is very good but has few issues, namely:

1. Populating to ListView code needs to be moved to onReceive of BroadCastReceiver where only the result will be available. In the case result is obtained at 2nd attempt.
2. BroadCastReceiver needs to be unregistered after the results are obtained.
3. size = size -1 seems unnecessary.

Find below the modified code of @Android as a working example:

Don't get confused with other option the snippet below I am using and will be useful for you too. Put the below htacces in your root.

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteRule    ^$    public/    [L]
    RewriteRule    (.*) public/$1    [L]
</IfModule>

Go to your public directory and put another htaccess file with the code snippet below

<IfModule mod_rewrite.c>
    RewriteEngine On
    # Removes index.php from ExpressionEngine URLs  
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?url=$1 [PT,L]

</IfModule>

Its working... !!!

Laravel Uses below .htaccess

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

You may be able to fix this error by name spacing :: the function call

comparison.cloud(colors = c("red", "green"), max.words = 100)

to

wordcloud::comparison.cloud(colors = c("red", "green"), max.words = 100)

closest() only looks for parents, I'm guessing what you really want is .find()

$(this).closest('.row').children('.column').find('.inputQty').val();

If you want to use Varun's ROBOCOPY command line in the Explorer context menu (i.e. right-click) here is a Windows registry import. I tried adding this as a comment to his answer, but the inline markup wasn't feasible.

I've tested this on my own Windows 10 PC, but use at your own risk. It will open a new command prompt, run the command, and pause so you can see the output.

1. Copy into a new text file:

   Windows Registry Editor Version 5.00

   [HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"

   [HKEY_CURRENT_USER\Software\Classes\directory\shell\Delete Empty Folders\command] @="C:\Windows\System32\Cmd.exe /C \"C:\Windows\System32\Robocopy.exe \"%V\" \"%V\" /s /move\" && PAUSE"

2. Rename the .txt extension to .reg

3. Double click to import.

If you don't have cocoa pods installed you need to sudo gem install cocoapods

1. run cd ios
2. run pod install
3. cd ..
4. delete build folder
5. run react-native run-ios

if error persists, 1. delete build folder again 2. open the /ios folder in x-code 3. navigate File -> Project Settings -> Build System -> change (Shared workspace settings and Per-User workspace settings): Build System -> Legacy Build System

If you creat user normally, you will not be able to login as password creation method may b different You can use default signup form for that

from django.contrib.auth.forms import UserCreationForm

You can extend that also

from django.contrib.auth.forms import UserCreationForm

class UserForm(UserCreationForm):
    mobile = forms.CharField(max_length=15, min_length=10)
    email = forms.EmailField(required=True)
    class Meta:
        model = User
        fields = ['username', 'password', 'first_name', 'last_name', 'email', 'mobile' ]

Then in view use this class

class UserCreate(CreateView):
    form_class = UserForm
    template_name = 'registration/signup.html'
    success_url = reverse_lazy('list')

    def form_valid(self, form):
        user = form.save()

The examples to os.walk in the documentation show how to do this:

for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        log = open(os.path.join(root, f),'r')

How did you expect the "open" function to know that the string "1" is supposed to mean "/home/des/test/1" (unless "/home/des/test" happens to be your current working directory)?

The mktemp(1) man page explains it fairly well:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win. A safer, though still inferior, approach is to make a temporary directory using the same naming scheme. While this does allow one to guarantee that a temporary file will not be subverted, it still allows a simple denial of service attack. For these reasons it is suggested that mktemp be used instead.

In a script, I invoke mktemp something like

mydir=$(mktemp -d "${TMPDIR:-/tmp/}$(basename $0).XXXXXXXXXXXX")

which creates a temporary directory I can work in, and in which I can safely name the actual files something readable and useful.

mktemp is not standard, but it does exist on many platforms. The "X"s will generally get converted into some randomness, and more will probably be more random; however, some systems (busybox ash, for one) limit this randomness more significantly than others

By the way, safe creation of temporary files is important for more than just shell scripting. That's why python has tempfile, perl has File::Temp, ruby has Tempfile, etc…

Obviously '12/01/2012 13:16:32.000' doesn't match 'DD-MON-YYYY hh24:mi' format.

Update:

You need 'MM/DD/YYYY hh24:mi:ss.ff' format and to use TO_TIMESTAMP instead of TO_DATE cause dates don't hold millis in oracle.

I usually use padding to resolve this issue. The padding will be added when border disappears and removed when border appears. Sample code:

.good-border {
  padding: 1px;
}

.good-border:hover {
  padding: 0px;
  border: 1px solid blue;
}

Actually this is the path and you should mention a valid path for this to work. If your data directory is in current directory then instead of my-data you should mention ./my-data, otherwise it will give you that error in mysql and mariadb also.

volumes:
 ./my-data:/var/lib/mysql

NOTE: I include this answer for completeness since the OP didn't mention what the data source is and we shouldn't make any assumptions.

This query gives the correct answer, but could be slower since it might have to sort all the items in People, depending on what data structure People is:

var oldest = People.OrderBy(p => p.DateOfBirth ?? DateTime.MaxValue).First();

UPDATE: Actually I shouldn't call this solution "naive", but the user does need to know what he is querying against. This solution's "slowness" depends on the underlying data. If this is a array or List<T>, then LINQ to Objects has no choice but to sort the entire collection first before selecting the first item. In this case it will be slower than the other solution suggested. However, if this is a LINQ to SQL table and DateOfBirth is an indexed column, then SQL Server will use the index instead of sorting all the rows. Other custom IEnumerable<T> implementations could also make use of indexes (see i4o: Indexed LINQ, or the object database db4o) and make this solution faster than Aggregate() or MaxBy()/MinBy() which need to iterate the whole collection once. In fact, LINQ to Objects could have (in theory) made special cases in OrderBy() for sorted collections like SortedList<T>, but it doesn't, as far as I know.

Setting null values can be done with np.nan:

import numpy as np
df.replace('-', np.nan)

Advantage is that df.last_valid_index() recognizes these as invalid.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

I don't know why, but if you use

(...)Formula = "=SUM(D2,E2)"

(',' instead of ';'), it works.

If you step through your sub in the VB script editor (F8), you can add Range("F2").Formula to the watch window and see what the formular looks like from a VB point of view. It seems that the formular shown in Excel itself is sometimes different from the formular that VB sees...

Testing $? is an anti-pattern.

if ./somecommand | grep -q 'string'; then
  echo "matched"
fi

If you can use .NET 4 or higher than use HasFlag() method

examples

letter.HasFlag(Letters.A | Letters.B) // both A and B must be set

same as

letter.HasFlag(Letters.AB)

You may use Map.entrySet() method:

for (Map.Entry entry : objectSet.entrySet())
{
    System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}

This is not right. Here's how you should use Runtime.exec(). You might also try its more modern cousin, ProcessBuilder:

Java Runtime.getRuntime().exec() alternatives

Matplotlib can handle directly and transparently jpg if you have installed PIL. You don't need to call it, it will do it by itself. If Python cannot find PIL, it will raise an error.

I ran into a similar situation trying to convert a table with several 100k rows with a C++ program (MFC/ODBC).

Since this operation took a very long time, I figured bundling multiple inserts into one (up to 1000 due to MSSQL limitations). My guess that a lot of single insert statements would create an overhead similar to what is described here.

However, it turns out that the conversion took actually quite a bit longer:

        Method 1       Method 2     Method 3 
        Single Insert  Multi Insert Joined Inserts
Rows    1000           1000         1000
Insert  390 ms         765 ms       270 ms
per Row 0.390 ms       0.765 ms     0.27 ms

So, 1000 single calls to CDatabase::ExecuteSql each with a single INSERT statement (method 1) are roughly twice as fast as a single call to CDatabase::ExecuteSql with a multi-line INSERT statement with 1000 value tuples (method 2).

Update: So, the next thing I tried was to bundle 1000 separate INSERT statements into a single string and have the server execute that (method 3). It turns out this is even a bit faster than method 1.

Edit: I am using Microsoft SQL Server Express Edition (64-bit) v10.0.2531.0

Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=http://download.java.net/maven/2/ \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT

The fundamental way to think about this subject is as follows:

A URI is a resource identifier that uniquely identifies a specific instance of a resource TYPE. Like everything else in life, every object (which is an instance of some type), have set of attributes that are either time-invariant or temporal.

In the example above, a car is a very tangible object that has attributes like make, model and VIN - that never changes, and color, suspension etc. that may change over time. So if we encode the URI with attributes that may change over time (temporal), we may end up with multiple URIs for the same object:

GET /cars/honda/civic/coupe/{vin}/{color=red}

And years later, if the color of this very same car is changed to black:

GET /cars/honda/civic/coupe/{vin}/{color=black}

Note that the car instance itself (the object) has not changed - it's just the color that changed. Having multiple URIs pointing to the same object instance will force you to create multiple URI handlers - this is not an efficient design, and is of course not intuitive.

Therefore, the URI should only consist of parts that will never change and will continue to uniquely identify that resource throughout its lifetime. Everything that may change should be reserved for query parameters, as such:

GET /cars/honda/civic/coupe/{vin}?color={black}

Bottom line - think polymorphism.

I reselected the Key(pfx) file in the "Choose a Strong Name Key File" drop-down box, Then provided password in the "ENTER PASSWORD" Popup Window. Saved my project and did rebuild.build succeeded.

• Open Project Properties.
• Click on the Signing section.
• Where it says ‘Choose a strong name key file:’, reselect the current value from the drop-down box:

• Visual Studio will now prompt you for the password. Enter it.

• Save your project and do a rebuild.

• If get error message:”An attempt was made to reference a token that does not exist” just ignore it and Continue the below steps

• Click the ‘Change Password” button:

• Enter the original password in all three boxes and click OK. If you’d like to change your password (or if your old password doesn’t meet complexity requirements), you can do so now.

• Save your project and do a rebuild.

You should not directly call the function exit(0) as it will quit the application immediately and will look like your app is crashed. So better to show users a confirmation alert and let them do this themselves.

Swift 4.2

func askForQuit(_ completion:@escaping (_ canQuit: Bool) -> Void) {
    let alert = UIAlertController(title: "Confirmation!", message: "Do you want to quit the application", preferredStyle: .alert)
    alert.addAction(UIAlertAction(title: "Yes", style: UIAlertAction.Style.default, handler: { (action) in
        alert.dismiss(animated: true, completion: nil)
        completion(true)
    }))
    alert.addAction(UIAlertAction(title: "No", style: UIAlertAction.Style.cancel, handler: { (action) in
        alert.dismiss(animated: true, completion: nil)
        completion(false)
    }))
    self.present(alert, animated: true, completion: nil)
}

/// Will quit the application with animation
func quit() {
    UIApplication.shared.perform(#selector(NSXPCConnection.suspend))
    /// Sleep for a while to let the app goes in background
    sleep(2)
    exit(0)
}

Usage:

self.askForQuit { (canQuit) in
     if canQuit {
         self.quit()
     }
}

Following are the steps to push Docker Image to Private Repository of DockerHub

1- First check Docker Images using command

docker images

2- Check Docker Tag command Help

docker tag help

3- Now Tag a name to your created Image

docker tag localImgName:tagName DockerHubUser\Private-repoName:tagName(tag name is optional. Default name is latest)

4- Before pushing Image to DockerHub Private Repo, first login to DockerHub using command

docker login [provide dockerHub username and Password to login]

5- Now push Docker Image to your private Repo using command

docker push [options] ImgName[:tag] e.g docker push DockerHubUser\Private-repoName:tagName

6- Now navigate to the DockerHub Private Repo and you will see Docker image is pushed on your private Repository with name written as TagName in previous steps

Memory leak: When there is a memory area in a heap but no variable in the stack pointing to that memory.

char *myarea=(char *)malloc(10);

char *newarea=(char *)malloc(10);

myarea=newarea;

Dangling pointer: When a pointer variable in a stack but no memory in heap.

char *p =NULL;

A dangling pointer trying to dereference without allocating space will result in a segmentation fault.

If you just need to set precision quantity and round the value, the right way to do this is use it's own object for this.

BigDecimal value = new BigDecimal("10.0001");
value = value.setScale(4, RoundingMode.HALF_UP);
System.out.println(value); //the return should be "10.0001"

One of the pillars of Oriented Object Programming (OOP) is "encapsulation", this pillar also says that an object should deal with it's own operations, like in this way:

In addition to all the mentions of StopIteration, the Python "for" loop simply does what you want:

>>> it = iter("hello")
>>> for i in it:
...     print i
...
h
e
l
l
o

First solution:
1. switch off Xorg access control: xhost +
2. Now start google chrome as normal user "anonymous" :
sudo -i -u anonymous /opt/google/chrome/chrome
3. When done browsing, re-enable Xorg access control:
xhost -
More info : Howto run google-chrome as root

Second solution:
1. Edit the file /opt/google/chrome/google-chrome
2. find exec -a "$0" "$HERE/chrome" "$@"
or exec -a "$0" "$HERE/chrome" "$PROFILE_DIRECTORY_FLAG" \ "$@"
3. change as
exec -a "$0" "$HERE/chrome" "$@" --user-data-dir ”/root/.config/google-chrome”

Third solution:
Run Google Chrome Browser as Root on Ubuntu Linux systems

There's a handy function, oidvectortypes, that makes this a lot easier.

SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes)) 
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

Credit to Leo Hsu and Regina Obe at Postgres Online for pointing out oidvectortypes. I wrote similar functions before, but used complex nested expressions that this function gets rid of the need for.

See related answer.

(edit in 2016)

Summarizing typical report options:

-- Compact:
SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes))

-- With result data type: 
SELECT format(
       '%I.%I(%s)=%s', 
       ns.nspname, p.proname, oidvectortypes(p.proargtypes),
       pg_get_function_result(p.oid)
)

-- With complete argument description: 
SELECT format('%I.%I(%s)', ns.nspname, p.proname, pg_get_function_arguments(p.oid))

-- ... and mixing it.

-- All with the same FROM clause:
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

NOTICE: use p.proname||'_'||p.oid AS specific_name to obtain unique names, or to JOIN with information_schema tables — see routines and parameters at @RuddZwolinski's answer.

The function's OID (see pg_catalog.pg_proc) and the function's specific_name (see information_schema.routines) are the main reference options to functions. Below, some useful functions in reporting and other contexts.

--- --- --- --- ---
--- Useful overloads: 

CREATE FUNCTION oidvectortypes(p_oid int) RETURNS text AS $$
    SELECT oidvectortypes(proargtypes) FROM pg_proc WHERE oid=$1;
$$ LANGUAGE SQL IMMUTABLE;

CREATE FUNCTION oidvectortypes(p_specific_name text) RETURNS text AS $$
    -- Extract OID from specific_name and use it in oidvectortypes(oid).
    SELECT oidvectortypes(proargtypes) 
    FROM pg_proc WHERE oid=regexp_replace($1, '^.+?([^_]+)$', '\1')::int;
$$ LANGUAGE SQL IMMUTABLE;

CREATE FUNCTION pg_get_function_arguments(p_specific_name text) RETURNS text AS $$
    -- Extract OID from specific_name and use it in pg_get_function_arguments.
    SELECT pg_get_function_arguments(regexp_replace($1, '^.+?([^_]+)$', '\1')::int)
$$ LANGUAGE SQL IMMUTABLE;

--- --- --- --- ---
--- User customization: 

CREATE FUNCTION pg_get_function_arguments2(p_specific_name text) RETURNS text AS $$
    -- Example of "special layout" version.
    SELECT trim(array_agg( op||'-'||dt )::text,'{}') 
    FROM (
        SELECT data_type::text as dt, ordinal_position as op
        FROM information_schema.parameters 
        WHERE specific_name = p_specific_name 
        ORDER BY ordinal_position
    ) t
$$ LANGUAGE SQL IMMUTABLE;

I guess you mean this:

class Value:
    def __init__(self, v=None):
        self.v = v

v1 = Value(1)
v2 = Value(2)

d = {'a': v1, 'b': v1, 'c': v2, 'd': v2}
d['a'].v += 1

d['b'].v == 2 # True

• Python's strings and numbers are immutable objects,
• So, if you want d['a'] and d['b'] to point to the same value that "updates" as it changes, make the value refer to a mutable object (user-defined class like above, or a dict, list, set).
• Then, when you modify the object at d['a'], d['b'] changes at same time because they both point to same object.

In Java you can't. Interface has to do with methods and signature, it does not have to do with the internal state of an object -- that is an implementation question. And this makes sense too -- I mean, simply because certain attributes exist, it does not mean that they have to be used by the implementing class. getHeight could actually point to the width variable (assuming that the implementer is a sadist).

(As a note -- this is not true of all languages, ActionScript allows for declaration of pseudo attributes, and I believe C# does too)

The most flexible approach would be using this method

Arr::sortByKeys(array $array, $keys, bool $assoc = true): array

here's why:

• You can sort by any key (also nested like 'key1.key2.key3' or ['k1', 'k2', 'k3'])

• Works both on associative and not associative arrays ($assoc flag)

• It doesn't use reference - return new sorted array

In your case it would be as simple as:

$sortedArray = Arr::sortByKeys($array, 'order');

This method is a part of this library.

By using pandas we can read excel easily.

import pandas as pd 
from pandas import ExcelWriter
from pandas import ExcelFile 

DataF=pd.read_excel("Test.xlsx",sheet_name='Sheet1')

print("Column headings:")
print(DataF.columns)

Test at :https://repl.it Reference: https://pythonspot.com/read-excel-with-pandas/

There is an errno module that defines standard exit codes:

For example, Permission denied is error code 13:

import errno, sys

if can_access_resource():
    do_something()
else:
    sys.exit(errno.EACCES)

In my case, we had several projects in one solution and had selected a different start project than in the package manager console when running the "Update-Database" Command with Code-First Migrations. Make sure to select the proper start project.

try this

    $("#mprDetailDataTable tr:gt(0)").each(function () {
        var this_row = $(this);
        var productId = $.trim(this_row.find('td:eq(0)').html());//td:eq(0) means first td of this row
        var product = $.trim(this_row.find('td:eq(1)').html())
        var Quantity = $.trim(this_row.find('td:eq(2)').html())
    });

Call "setWarningMsg()" Method and pass the text that you want to show.

exm:- setWarningMsg("thank you for using java");


public static void setWarningMsg(String text){
    Toolkit.getDefaultToolkit().beep();
    JOptionPane optionPane = new JOptionPane(text,JOptionPane.WARNING_MESSAGE);
    JDialog dialog = optionPane.createDialog("Warning!");
    dialog.setAlwaysOnTop(true);
    dialog.setVisible(true);
}

Or Just use

JOptionPane optionPane = new JOptionPane("thank you for using java",JOptionPane.WARNING_MESSAGE);
JDialog dialog = optionPane.createDialog("Warning!");
dialog.setAlwaysOnTop(true); // to show top of all other application
dialog.setVisible(true); // to visible the dialog

You can use JOptionPane. (WARNING_MESSAGE or INFORMATION_MESSAGE or ERROR_MESSAGE)

This my variant of the solution based on LINQ and the Descendants method of the XDocument class

using System;
using System.Linq;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XDocument xml = XDocument.Parse(@"
        <root>
          <child id='1'/>
          <child id='2'>
            <subChild id='3'>
                <extChild id='5' />
                <extChild id='6' />
            </subChild>
            <subChild id='4'>
                <extChild id='7' />
            </subChild>
          </child>
        </root>");

        xml.Descendants().Where(p => p.Name.LocalName == "extChild")
                         .ToList()
                         .ForEach(e => Console.WriteLine(e));

        Console.ReadLine();
    }
}

Results:

For more details on the Desendants method take a look here.

You could use the count() function to see how many entries there are in the $_SESSION array. This is not good practice. You should instead set the id of the user (or something similar) to check wheter the session was initialised or not.

if( !isset($_SESSION['uid']) )
    die( "Login required." );

(Assuming you want to check if someone is logged in)

It is also possible to round negative integers

// performing d = c * 3/4 where d can be pos or neg
d = ((c * a) + ((c>0? (b>>1):-(b>>1)))) / b;
// explanation:
// 1.) multiply:          c * a  
// 2.) if c is negative:  (c>0? subtract half of the dividend 
//                              (b>>1) is bit shift right = (b/2)
//     if c is positive:  else  add half of the dividend 
// 3.) do the division
// on a C51/52 (8bit embedded) or similar like ATmega the below code may execute in approx 12cpu cycles (not tested)

Extended from a tip somewhere else in here. Sorry, missed from where.

   int s=c;
   int e=c+10;


   for(int f=s; f<=e; f++) {
      printf("%d\t",f);

      double cd=f, ad=a, bd=b , dd;

      // d = c * 3/4  with double
      dd = cd * ad / bd;

      printf("%.2f\t",dd);
      printf("%.1f\t",dd);        
      printf("%.0f\t",dd);

      // try again with typecast have used that a lot in Borland C++ 35 years ago....... maybe evolution has overtaken it ;) ***
      // doing div before mul on purpose
      dd =(double)c * ((double)a / (double)b);
      printf("%.2f\t",dd);

      c=f;
      // d = c * 3/4  with integer rounding
      d = ((c * a) + ((c>0? (b>>1):-(b>>1)))) / b;
      printf("%d\t",d);
      puts("");
  }
 return 0;

This was confirmed in the Chromedriver issue tracker: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1797#c1

Yes, Chromedriver works on 64-bit Windows and against 64-bit Chrome successfully.

I came here while searching for the answer to if it works on 64-bit Chrome following the announcement that from version 58 Chrome will default to 64-bit on Windows provided certain conditions are met:
https://chromereleases.googleblog.com/2017/05/stable-channel-update-for-desktop.html

In order to improve stability, performance, and security, users who are currently on 32-bit version of Chrome, and 64-bit Windows with 4GB or more of memory and auto-update enabled will be automatically migrated to 64-bit Chrome during this update. 32-bit Chrome will still be available via the Chrome download page.

Don't Return Empty Json

In My Case I was returning Empty Json String in .Net Core Web API Project.

So I Changed My Code

From

 return Ok();

To

 return Ok("Done");

It seems you have to return some string or object.

Hope this helps.

It's simple please follow the below step.

1. On IntelliJ press 'Ctrl Alt + S' [ press ctrl alt and S together], this will open 'Setting popup'
2. In Search panel 'left top search 'Theme' keyword.
3. In left panel itself you can see 'Appearance', click on this

4. Right side panel you can see Theme: and drop down with following option

   • Dracula
   • IntelliJ
   • Windows

just select which ever you want and click on apply and Ok.

I hope this may work for you..

I misunderstood question. Sorry. for editor - File->Settings->Editor->Colors &Fonts and choose your scheme.... :)

Well previously, I used the approach that you can find inside the WebElement:

WebElement baseTable = driver.findElement(By.tagName("table"));
WebElement tableRow = baseTable.findElement(By.xpath("//tr[2]")); //should be the third row
webElement cellIneed = tableRow.findElement(By.xpath("//td[2]"));
String valueIneed = cellIneed.getText();

Please note that I find inside the found WebElement instance.

The above is Java code, assuming that driver variable is healthy instance of WebDriver

For the sake of completion: if you want to convert fixed point representation to its binary equivalent you can perform the following operations:

1. Get the integer and fractional part.

   from decimal import *
   a = Decimal(3.625)
   a_split = (int(a//1),a%1)
   

2. Convert the fractional part in its binary representation. To achieve this multiply successively by 2.

   fr = a_split[1]
   str(int(fr*2)) + str(int(2*(fr*2)%1)) + ...
   

You can read the explanation here.

from pathlib import Path
import os

sorted(Path('./').iterdir(), key=lambda t: t.stat().st_mtime)

or

sorted(Path('./').iterdir(), key=os.path.getmtime)

or

sorted(os.scandir('./'), key=lambda t: t.stat().st_mtime)

where m time is modified time.

Just document it here on Windows you need to escape the \ character:

"e:\\directory\\-"

Set equal name attributes to create a group;

<form>_x000D_
  <fieldset id="group1">_x000D_

    <input type="radio" value="value2" name="group1">_x000D_
  </fieldset>_x000D_
_x000D_
  <fieldset id="group2">_x000D_
    <input type="radio" value="value1" name="group2">_x000D_
    <input type="radio" value="value2" name="group2">_x000D_
    <input type="radio" value="value3" name="group2">_x000D_
  </fieldset>_x000D_
</form>

I would personally use an <svg> tag because if you do you have full control over it. If you do use it in <img> you don't get to control the innards of the SVG with CSS etc.

another thing is browser support.

Just open your svg file and paste it straight into the template.

Seeing a user banging away at a control that overrides her decisions is a sad sight. Set the control's Enabled property to False. If you don't like that then change its Items property so only one item is selectable.

As other answers suggest... Some guy (for whatever reason) decided that your old code should not work when you upgrade your PHP, because he knows better than you and don't care about what your code does or how simple it is for you to upgrade.

Well, if you can't upgrade your project overnight you can

downgrade your version of PHP to whatever version that worked

or...

use a shim (kind of polyfill) such as https://github.com/dshafik/php7-mysql-shim or https://github.com/dotpointer/mysql-shim, and then find a place for include_once("choice_shim.php"); somewhere in your code

That will keep your old PHP code up and running until you are in a mood to update...

There is another javascript library based on SVG. It is called Protovis and it comes from Stanford Visualization Group

It also allows making nice interactive graphics and visualizations.

http://vis.stanford.edu/protovis/ex/

Although it is only for modern web browsers

UPDATE: The protovis team has moved to another library called d3.js (Data Driven Documents) as they said:

"The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. D3 builds on many of the concepts in Protovis"

The new library can now be found in:

http://mbostock.github.com/d3/

UPDATE 2:

"Rickshaw" is a JavaScript toolkit for creating interactive time series graphs. Based on d3.js that simplifies a lot the work with d3.js although is a little bit less powerful.

The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:

pip install xlrd==1.2.0

There are several options... assuming you found your TD by var td = document.getElementyById('myTD_ID'); you can do:

• td.innerHTML = "mytext";

• td.textContent= "mytext";

• td.innerText= "mytext"; - this one may not work outside IE? Not sure

• Use firstChild or children array as previous poster noted.

If it's just the text that needs to be changed, textContent is faster and less prone to XSS attacks (https://developer.mozilla.org/en-US/docs/Web/API/Node.textContent)

Personally I extract the POST array and then have if(!$login || !$password) then echo fill out the form :)

I need a regex able to match everything but except a string starting with index.php a specific pattern (specifically index.php and what follows, like index.php?id=2342343)

Use method Exec

    let match,_x000D_
        arr = [],_x000D_
        myRe = /([\s\S]+?)(?:index\.php\?id.+)/g;_x000D_
_x000D_
    var str = 'http://regular-viragenia/index.php?id=2342343';_x000D_
_x000D_
    while ((match = myRe.exec(str)) != null) {_x000D_
         arr.push(match[1]);_x000D_
    } _x000D_
    _x000D_
    console.log(arr);

var myRe = /([\s\S]+?)(?:index\.php\?id=.+)/g;_x000D_
var str = 'http://regular-viragenia/index.php?id=2342343';_x000D_
var matches_array = myRe.exec(str);_x000D_
console.log(matches_array[1]);

OR OTHER MATCH

let match,_x000D_
            arr = [],_x000D_
            myRe = /index.php\?id=((?:(?!index)[\s\S])*)/g;_x000D_
_x000D_
        var str = 'http://regular-viragenia/index.php?id=2342343index.php?id=111index.php?id=222';_x000D_
_x000D_
        while ((match = myRe.exec(str)) != null) {_x000D_
             arr.push(match[1]);_x000D_
        } _x000D_
_x000D_
        console.log(arr);

The most important thing to realize is that, using Linq, the query does not get evaluated immediately. It is only run as part of iterating through the resulting IEnumerable<T> in a foreach - that's what all the weird delegates are doing.

So, the first example evaluates the query immediately by calling ToList and putting the query results in a list.
The second example returns an IEnumerable<T> that contains all the information needed to run the query later on.

In terms of performance, the answer is it depends. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable<T> to take a long time) use a list. Else use an IEnumerable<T>. The default should be to use the on-demand evaluation in the second example, as that generally uses less memory, unless there is a specific reason to store the results in a list.

The Android Developer Guide has a section called Building Custom Components. Unfortunately, the discussion of XML attributes only covers declaring the control inside the layout file and not actually handling the values inside the class initialisation. The steps are as follows:

1. Declare attributes in values\attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="MyCustomView">
        <attr name="android:text"/>
        <attr name="android:textColor"/>            
        <attr name="extraInformation" format="string" />
    </declare-styleable>
</resources>

Notice the use of an unqualified name in the declare-styleable tag. Non-standard android attributes like extraInformation need to have their type declared. Tags declared in the superclass will be available in subclasses without having to be redeclared.

2. Create constructors

Since there are two constructors that use an AttributeSet for initialisation, it is convenient to create a separate initialisation method for the constructors to call.

private void init(AttributeSet attrs) { 
    TypedArray a=getContext().obtainStyledAttributes(
         attrs,
         R.styleable.MyCustomView);

    //Use a
    Log.i("test",a.getString(
         R.styleable.MyCustomView_android_text));
    Log.i("test",""+a.getColor(
         R.styleable.MyCustomView_android_textColor, Color.BLACK));
    Log.i("test",a.getString(
         R.styleable.MyCustomView_extraInformation));

    //Don't forget this
    a.recycle();
}

R.styleable.MyCustomView is an autogenerated int[] resource where each element is the ID of an attribute. Attributes are generated for each property in the XML by appending the attribute name to the element name. For example, R.styleable.MyCustomView_android_text contains the android_text attribute for MyCustomView. Attributes can then be retrieved from the TypedArray using various get functions. If the attribute is not defined in the defined in the XML, then null is returned. Except, of course, if the return type is a primitive, in which case the second argument is returned.

If you don't want to retrieve all of the attributes, it is possible to create this array manually.The ID for standard android attributes are included in android.R.attr, while attributes for this project are in R.attr.

int attrsWanted[]=new int[]{android.R.attr.text, R.attr.textColor};

Please note that you should not use anything in android.R.styleable, as per this thread it may change in the future. It is still in the documentation as being to view all these constants in the one place is useful.

3. Use it in a layout files such as layout\main.xml

Include the namespace declaration xmlns:app="http://schemas.android.com/apk/res-auto" in the top level xml element. Namespaces provide a method to avoid the conflicts that sometimes occur when different schemas use the same element names (see this article for more info). The URL is simply a manner of uniquely identifying schemas - nothing actually needs to be hosted at that URL. If this doesn't appear to be doing anything, it is because you don't actually need to add the namespace prefix unless you need to resolve a conflict.

<com.mycompany.projectname.MyCustomView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:text="Test text"
    android:textColor="#FFFFFF"
    app:extraInformation="My extra information"
/> 

Reference the custom view using the fully qualified name.

Android LabelView Sample

If you want a complete example, look at the android label view sample.

LabelView.java

 TypedArray a=context.obtainStyledAttributes(attrs, R.styleable.LabelView);
 CharSequences=a.getString(R.styleable.LabelView_text);

attrs.xml

<declare-styleable name="LabelView">
    <attr name="text"format="string"/>
    <attr name="textColor"format="color"/>
    <attr name="textSize"format="dimension"/>
</declare-styleable>

custom_view_1.xml

<com.example.android.apis.view.LabelView
    android:background="@drawable/blue"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    app:text="Blue" app:textSize="20dp"/>

This is contained in a LinearLayout with a namespace attribute: xmlns:app="http://schemas.android.com/apk/res-auto"

Github blog spoke yesterday about Egit plugin:

http://freshmeat.net/projects/jgit/

You can add the model error on any property of your model, I suggest if there is nothing related to create a new property.

As an exemple we check if the email is already in use in DB and add the error to the Email property in the action so when I return the view, they know that there's an error and how to show it up by using

<%: Html.ValidationSummary(true)%>
<%: Html.ValidationMessageFor(model => model.Email) %>

and

ModelState.AddModelError("Email", Resources.EmailInUse);

You can use the Path api:

Path p = Paths.get(yourFileNameUri);
Path folder = p.getParent();

The Maven Dependency Plugin will help, especially the dependency:analyze goal:

dependency:analyze analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.

Another thing that might help to do some cleanup is the Dependency Convergence report from the Maven Project Info Reports Plugin.

Procedural Implementation of Marc B's Answer after refining Sergey Telshevsky's Answer.

function strip_param_from_url( $url, $param )
{
    $base_url = strtok($url, '?');              // Get the base url
    $parsed_url = parse_url($url);              // Parse it 
    $query = $parsed_url['query'];              // Get the query string
    parse_str( $query, $parameters );           // Convert Parameters into array
    unset( $parameters[$param] );               // Delete the one you want
    $new_query = http_build_query($parameters); // Rebuilt query string
    return $base_url.'?'.$new_query;            // Finally url is ready
}

// Usage
echo strip_param_from_url( 'http://url.com/search/?location=london&page_number=1', 'location' )

the first command is correct but change from convert to export to csv, as below,

Get-ADUser -Filter * -Properties * `
    | Select-Object -Property Name,SamAccountName,Description,EmailAddress,LastLogonDate,Manager,Title,Department,whenCreated,Enabled,Organization `
    | Sort-Object -Property Name `
    | Export-Csv -path  C:\Users\*\Desktop\file1.csv

Yes you can, with public static members on an outer public class, like so:

public class Foo {

    public static class FooChild extends Z {
        String foo;
    }

    public static class ZeeChild extends Z {

    }

}

and another file that references the above:

public class Bar {

    public static void main(String[] args){

        Foo.FooChild f = new Foo.FooChild();
        System.out.println(f);

    }
}

put them in the same folder. Compile with:

javac folder/*.java

and run with:

 java -cp folder Bar

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

You can adjust the subplot geometry in the very tight_layout call as follows:

fig.tight_layout(rect=[0, 0.03, 1, 0.95])

As it's stated in the documentation (https://matplotlib.org/users/tight_layout_guide.html):

tight_layout() only considers ticklabels, axis labels, and titles. Thus, other artists may be clipped and also may overlap.

function formatBytes($bytes, $precision = 2) { 
    $units = array('B', 'KB', 'MB', 'GB', 'TB'); 

    $bytes = max($bytes, 0); 
    $pow = floor(($bytes ? log($bytes) : 0) / log(1024)); 
    $pow = min($pow, count($units) - 1); 

    // Uncomment one of the following alternatives
    // $bytes /= pow(1024, $pow);
    // $bytes /= (1 << (10 * $pow)); 

    return round($bytes, $precision) . ' ' . $units[$pow]; 
} 

(Taken from php.net, there are many other examples there, but I like this one best :-)

You can use java.util.Calendar class to get time in milliseconds. Example:

Calendar cal = Calendar.getInstance();
int milliSec = cal.get(Calendar.MILLISECOND);
// print milliSec

java.util.Date date = cal.getTime();
System.out.println("Output: " +  new SimpleDateFormat("yyyy/MM/dd-HH:mm:ss:SSS").format(date));

Try to upgrade and install new packages

sudo apt-get update && sudo apt-get upgrade -y

Using regular ng-view module you cannot have more than one dynamic template.

However, this project enables you to do so (look for ui-router).

I can tell you for Windows.

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

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

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

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

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

Note: Do not add package in your main class.

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

6. Check the output in the console.

Done, hope this helps.

Try this:

select CONVERT(VARCHAR(5), ' 4:07PM', 108) + ' ' + RIGHT(CONVERT(VARCHAR(30), ' 4:07PM', 9),2) as ConvertedTime

What about

typeof(IWhatever).GetTypeInfo().IsInterface

ArrayList<ArrayList> arrObjList = new ArrayList<ArrayList>();
ArrayList<Double> arrObjInner1= new ArrayList<Double>();
arrObjInner1.add(100);
arrObjInner1.add(100);
arrObjInner1.add(100);
arrObjInner1.add(100);

arrObjList.add(arrObjInner1);

You can have as many ArrayList inside the arrObjList. I hope this will help you.

Try this,

1. If you want to skip a particular iteration, use continue.

2. If you want to break out of the immediate loop use break

3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from the inner loop, use break with label.

eg:

continue

for(int i=0 ; i<5 ; i++){

    if (i==2){

      continue;
    }
 }

eg:

break

for(int i=0 ; i<5 ; i++){

        if (i==2){

          break;
        }
     }

eg:

break with label

lab1: for(int j=0 ; j<5 ; j++){
     for(int i=0 ; i<5 ; i++){

        if (i==2){

          break lab1;
        }
     }
  }

this.donorsTableAdapter.Fill(this.sbmsDataSet.donors);

As mentioned here, you might need to disable the loopback

Loopback check can be removed by adding a registry entry as follows:

• Edit the registry using regedit. (Start –> Run > Regedit )
• Navigate to: HKLM\System\CurrentControlSet\Control\LSA
• Add a DWORD value called “DisableLoopbackCheck” Set this value to 1

You can specify any extra header you may need with -a

$mail -s "Some random subject" -a "From: [email protected]" [email protected]

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

Following bootstrap 4 classes helped me solve this

<div class="col text-center justify-content-center align-self-center">

Mongoose Models inherit from Documents, which have a toObject() method. I believe what you're looking for should be the result of doc.toObject().

http://mongoosejs.com/docs/api.html#document_Document-toObject

Based on the same idea as Super Type Tokens, you could create a typed id to use instead of a string:

public abstract class TypedID<T extends Animal> {
  public final Type type;
  public final String id;

  protected TypedID(String id) {
    this.id = id;
    Type superclass = getClass().getGenericSuperclass();
    if (superclass instanceof Class) {
      throw new RuntimeException("Missing type parameter.");
    }
    this.type = ((ParameterizedType) superclass).getActualTypeArguments()[0];
  }
}

But I think this may defeat the purpose, since you now need to create new id objects for each string and hold on to them (or reconstruct them with the correct type information).

Mouse jerry = new Mouse();
TypedID<Dog> spike = new TypedID<Dog>("spike") {};
TypedID<Duck> quacker = new TypedID<Duck>("quacker") {};

jerry.addFriend(spike, new Dog());
jerry.addFriend(quacker, new Duck());

But you can now use the class in the way you originally wanted, without the casts.

jerry.callFriend(spike).bark();
jerry.callFriend(quacker).quack();

This is just hiding the type parameter inside the id, although it does mean you can retrieve the type from the identifier later if you wish.

You'd need to implement the comparison and hashing methods of TypedID too if you want to be able to compare two identical instances of an id.

Give your body tag an overflow: scroll;

body {
    overflow: scroll;
}

or if you only want a vertical scrollbar use overflow-y

body {
    overflow-y: scroll;
}

i had same problem and i am using a wamp

Solution : Open file : config/database.php

'engine' => null, => 'engine' => 'InnoDB',

Thanks

Some time when we use Environ() function we may get the Library or property not found error. Use VBA.Environ() or VBA.Environ$() to avoid the error.
